Anadarko submitted revised Exhibits A & B to the JLU Agreement reflecting the lease relinquishments. Under Anadarko's request, two leases - ADLs 389164 and 389165- would remain in the JLU until December 31, 2008. The Division accepts Anadarko's voluntary relinquishment of the JLU leases listed above. They expired, effective November 1, 2008. The JLU Agreement maybe terminated by an affirmative vote of the working interest owners and the Commissioner's approval. The Division approves the requested JLU termination effective December 31, 2008, under Article 14.5 of the Agreement and 11 AAC 83.336(c). Under Article 15.2 of the Agreement and 11 AAC 83.140, ADLs 389164 and 389165 will continue in full force and effect for 90 days from the date of the JLU termination, that is, until March 31, 2009, and so long thereafter as drilling or redrilling operations are being conducted on them and so long thereafter as oil or gas is produced in paying quantities. Ties unit termination approval does not relieve Anadarko from its obligations under Article 15.3 of the Agreement and the individual leases, including its responsibility for well and facility abandonment and lease surface restoration.

You alf did submit a 403 to re-enter the suspended well and a 407 was a requirement of that approval. The 407 submitted for Jacob's Ladder C-A is not applicable to the "C". I would expect that it should only be necessary to duplicate the 407 from last year and check a few more boxes. The operations reports would cover until the sidetrack was initiated. Thanks in advance. Call or message with any questions.

Mr. Maunder, Anadarko Petroleum Corp. drilled a significant portion of the captioned well last tundra travel season.. After setting 9-5/8" intermediate casing in the Kavik, 432' of new hole was drilled stopping in the top of the Lisburne. Subsequently, the operations were suspended (see diagrams) and the rig was de-mobilized back to Deadhorse. During the coming tundra travel season, Anadarko intends to finish drilling the suspended well. Since operations were suspended in April 2007, the bottom hole location (target) has changed. The new target is over 2000' away from the original target and it is 844' TVD deeper. Therefore, a revised (or new) application for permit to drill is required. A 10-403 for to re-enter a suspended well and a 10-401 are both attached. Pending approval of these applications, Anadarko intends to re-enter the original hole and clean it out to (or near to) its suspended TD. This will be a directionally drilled extension of the original wellbore that was never finished. The change in bottom hole location requires a revised 10-401. The re-entry of a suspended well requires a 10-403. A detailed program is attached. Operational steps 1 through 6 are applicable to the 10-403. The remaining steps are applicable to the 10-401. In general our operational program includes, building an ice road and pad, mobilizing Akita 63 back to location, drilling out to (or near to) the original TD, directionally drilling to the new target, completing and testing the well. When we are finished with the testing program, produced fluids will be re-injected back into the Lisburne formation and then the well will be plugged. Finally, Akita 63 will be de-mobilized back to Deadhorse. We respectfully request approval of this revised application for permit to drill and accompanying Sundry Notice including a BOP test pressure of 5000 psi (as was the case on the original permit to drill). The necessary data is attached. If you have any questions or comments, please direct them to Skip Coyner at (907) 273-6305.

Supervisor Alaska Oil and Gas Conservation Commission DATE: April 5, 2007 FROM: Jeff Jones Petroleum Inspector SUBJECT: P&A Jacobs LadderC Anadarko Petroleum PTD 206-152 Exploration April 5, 2007: I traveled to the Doyon-Akita Rig 63 at Anadarko Petroleum's Jacob's Ladder C exploratory well site to witness the deployment and pressure ~ test of a cement retainer plug for temporary abandonment of this well. Darrel Greene was the Anadarko representative for the test today. Mr. Green informed me that this well has a cement plug founded on bottom and the top of cement was tagged at 10,918' MD. The retainer was set via wire line at 10,893' MD per approval of Tom Maunder (AOGCC), the blind rams were closed and the well bore was pressured up to 2850 PSI. No pressure loss was observed over a a/ 20-minute period. Summary: I witnessed the successful deployment and pressure test of a wire line conveyed well bore retainer plug for temporary abandonment of Anadarko Petroleum's exploratory well Jacob's Ladder C.

Tom Maunder, PE AOGCC Rowe, Chuck wrote, On 4/5/2007 6:56 AM: Tom- We completed setting a balanced cement plug yesterday afternoon from TD @ 11,437' to back inside the 9 5/8" casing. We ran in with wireline and an 8" gauge ring this morning and tagged TOC at 10,918' which indicated 88' of cement inside the 9 5/8" casing which is 12' short of the required plug length inside the 9 5/8" casing. Following are the details of the job: • Well TD = 11,437 MD • 9 5/8" 53.5 ppf casing shoe set @11,006' MD • Required TOC (assuming 100' lap) inside 9 5/8" casing = 10,906' MD • Measured TOC = 10,918' WLM • Slurry volume required as per open hole caliper = 30.63 bbls • Open Hole Excess of 10% slurry mixed = 3.06 bbls • Slurry required for 100' lap inside 9 5/8" casing = 7.08 bbls • Total slurry mixed and pumped = 40.77 bbls (= 149.6 sxs @ yield of 1.53 cf/sx) I would like to request that a variance be granted on the top of cement required inside the 9 5/8" casing so that we may proceed with the suspension program as previously detailed in the Sundry Application.

Chuck, The document you provided contains the text contained below. Placing the plugs as planned should isolate the formations below the 9-5/8" shoe and preserve the wellbore for re-entry next year. By copy of this email you have "verbal" approval to proceed. When the actual cement calculations are available for the deep plug, please provide them via email. Have your Drilling Supervisor contact the Inspectors to for witness of the work. In particular, the Inspectors should be given an opportunity to witness the tagging of the cement plug and setting of the bridge plug. Call or message with any questions. Tom Maunder, PE AOGCC Thomas Maunder wrote, On 4/3/2007 7:46 AM: Good Morning Chuck,. The procedure is what. was discussed. With regard to the sundry, you do not need to have an exact sack count or specific depth for the plugs in order to submit the application for approval. It is understood that some adjustment in the volumes and depths may be necessary. I look forward to receiving the sundry. Call or message with any questions. Tom Maunder, PE AOGCC Rowe, Chuck wrote, On 4/2/2007 6:25 PM: Tom- As discussed via telecom earlier today, Anadarko reached a depth of 11,437' MD in the 8 1/2" hole section of the Jacob's Ladder well early this morning. Drilling was stopped at this point due to the bit dulling. Based on formation top picks from mud logs it is estimated that approximately 182 ft of penetration has been made into the Lisburne formation. Due to time constraints that result from the upcoming tundra closure Anadarko and its partners have elected to cease drilling on the Jacob's Ladder C well for the 2006 / 2007 winter season and begin wireline logging operations in the 8 1/2" hole section and ultimately begin steps to operationally suspend the well for this season. Following is a proposed plan for operational suspension of the Jacob's Ladder C well for the 2006 /2007 winter season: 1. POOH and lay down 8 1/2" BHA. 2.

(Note: the 9 5/8" x 13 3/8" annulus has already been freeze protected). 12. Set Christmas tree with a blanking plug and test tree, then install BPV. 13. Install AOGCC required signage at location. 14. RDMO Your review of and concurrence with this proposed program is requested. A Sundry Notice associated with the operational suspension of the well will be filed as soon as some of the final cement plug and bridge plug setting depths are established.

Either course of action will require a sundry notice and if it is possible, in advance would be appreciated. Please look at the regulation for suspended wells. One other freeze protection issue would be 9-5/8" x 13-3/8" annulus. You likely have that in mind, but I wanted to mention it. The actual deep plug could change too, depending on your drilling results. Call or message with any questions.

Good luck. I would certainly hope that it is not necessary to pump all the cement you have available. Call or message with any questions. Tom Maunder, PE AOGCC Rowe, Chuck wrote, On 3/8/2007 3:15 PM: Tom- Thanks for your consideration of Anadarko's proposal and for allowing us to proceed with operations at this point. Subsequent to submitting Anadarko's request for waiver to you earlier this afternoon, the 1"tubing was RIH and TOC was tagged at 289', considerably shallower than expected. The status at well site at the time of this writing is that we are in the annulus with 1" tbg just above our tag depth. We have sufficient quantities of cement to pump +/- 970 bbls of cement slurry. Since under the provisions of the waiver you have granted to Anadarko, we still have the obligation to cement the 20" x 13 3/8" annulus before the end of season, I have just recommended to Anadarko management and received approval to go ahead and pump the quantity of cement I have on location as described above. With the idea, that if we get cement returns to surface we have met all regulatory obligations for cementing the annulus and can continue with wellhead and BOP installation. If we do not receive cement returns to surface we would propose to POOH with 1" tbg. Cut a hole in the 20" casing to facilitate re-running the 1"tubing inside the 20" x 13 3/8" annulus as proposed in my eariier plan to you and plan on performing the remaining cementation of the annulus some time prior to the release of the Akita 63 rig from the Jacob's Ladder well this drilling season. Your concurrence with the revised plan as described above is respectfully requested.

Cc: AOGCC North Slope Office Subject: Re: Jacob's Ladder CWell -Request For Waiver On Cement Top Job Requirement For 20" x 13 3/8" Annulus Chuck, My colleagues and I have looked at your proposal and find it acceptable for Anadarko to proceed with plans to drill ahead. Your provision to install the 1 " for future cementing operations is appropriate.'-Please note that placing cement in the 20" (nominal?) x 13-3/8" annulus is not optional as stated in your proposed plan. It is acknowledged that the ultimate disposition of the well is dependent on determinations after reaching the objective formation, however plans to cement that annulus should still be maintained. Operations within the wellbore should provide heat sufficient to keep the annulus thawed for ultimate cementing. Good luck with the operations. Call or message with any questions. Tom Maunder, PE AOGCC Rowe, Chuck wrote, On 3/8/2007 12:46 PM: Tom- As you are aware from our prior. telephone communications, Anadarko failed to get cement returns to surface on the 20" x 13 3/8" annulus during the primary cementation of the 13 3/8" casing of the Jacob's Ladder C well. Subsequent to that, 1"tubing was run into the 20" x 13 3/8" annulus and TOC was tagged at 622'. The tubing was raised 12' (EOT = 610') to facilitate RU of cementing lines. A total of 625 sxs (506 bbls) of 10.7 ppg ASL cement was pumped. Full mud returns were ', observed during the cement top job, however, no cement returns were observed at surface. Final MW In = 9.3 ppg, MW Out = 9.9 ppg. Upon POOH w/ 1"tubing, cement was observed on the lower 120' of tubing. From this observation, it is estimated that the 506 bbls of slurry pumped effectively filled 132' of annular space, thus resulting in and estimated TOC now at 490' in the 20" x 13 3/8" annulus. ', The purpose of this communication is to request a waiver from AOGCC on the requirement to fill the 20" x 13 3/8" annulus with cement at this time. Jacob's Ladder C is an exploratory well. The well's objective is the Lisburne formation. If Anadarko is unsuccessful in finding commercial quantities of hydrocarbons in the Lisburne formation the well will be plugged and abandoned as per AOGCC regulations. Under this scenario there may be no technical need for Anadarko to fill the remainder of the 20" x 13 3/8" annulus with cement. If Anadarko is successful in finding commercial quantities of hydrocarbons in the Lisburne and it is determined that the well will be retained as a production or utility well, Anadarko would seek guidance from AOGCC on the need to fill the remainder of the 20" x 13 3/8" annulus at the time it is determined the well will be retained. Under this latter scenario, Anadarko would undertake the necessary operations to fill the 20" x 13 3/8" annulus as directed by AOGCC. To facilitate the cementing of the 20" x 13 3/8" annulus at a later date Anadarko proposes the following program for performing a future cement top job on the 20" x 13 3/8"annulus: • Cut a hole in the wall of the 20" conductor casing of sufficient size to allow 1" tubing to be run into the 20" x 13 3/8" annulus. • RIH with 1"tubing until TOC is tagged. PU 10' and RU lines to the top of the 1" tubing. Report the TOC to the Anadarko Drilling Manager and the AOGCC. • Break circulation thru the 1"tubing to insure that the tubing I.D. is clear. RD pumping lines. • Secure the 1"tubing at surface utilizing a "dog collar clamp" or suitable alternative method. Re: Jacob's Ladder CWell -Request For Waiv~ Cement Top Jo... • Cap the top of the 1"tubing to prohibit debris from getting inside the tubing. • Install a protective cover over the top of the 1" tubing to prohibit damage to the tubing during future drilling operations. • Report details of the 1"tubing installation in the 20" x 13 3/8" annulus in the Anadarko Daily Drilling Report, IADC Daily Drilling Report and AOGCC weekly report submitted by Anadarko. • At which time it is determined that the Jacob's Ladder C well will be retained as a production or utility well, consult with AOGCC on the requirement for performing a cement top job in the 20" x 13^3/8" annulus. Anadarko respectfully requests your consideration of this request to waive the requirements for cementing the remainder of the 20" x 13 3/8" annulus at this time.

I have not done the calculation, however since you indicated that dye was added about 100 bbls ahead of the cement and it was seen there is reason to believe that the cement should not be too far down. The wild card is the hole diameter. I understand that Inspector Lou Grimaldi has been in contact with Darrel and will likely be there when the job is pumped. I certainly hope that you only need a fraction of the 1 " you will have available. One other item, do you have values for the pressures while pumping and displacing the cement? For a good portion of the lead slurry the casing should have been full of cement. If you have a graph from Schlumberger I'd appreciate if you could send it. Is the 200' TOC based on lift pressure?

RE: [Fwd: RE: Anadarko Jacob's Ladder 13 3~ement Job] I must first apologize for providing you with two bits of incorrect information during our telephone conversation this morning. The first issue involves the casing setting depth. The actual casing setting depth is 3,429,14' and not 3442' as previously reported. 1 had forgotten that we set the shoe 13' high to allow sufficient rat hole to facilitate the landing of the 13 3/8" mandrel type casing hanger at surface. The second issue involved the type and density of the tail slurry. The actual slurry was Schlumberger Deep-Crete mixed at 12.5 ppg and not Class G at 15.8 ppg. We had a "cut and paste" error in the cement program document that I was reading from when I provided you the slurry information. You were correct in your initial assessment of the slurry. I've attached a spreadsheet showing the pre-job calculations utilized for the 13 3/8" casing job. The only deviation from that summary is the fact that we did not bump the wiper plug and as a result of this we pumped 7 bbls additional displacement (e.g.- 1/2 of the shoe track volume) over the theoretical displacement before shutting down pumps. With regards to our plan forward, we've mobilized an additional 1000' of 1"tubing bringing the quantity on location to 1,100'. We hope to begin RIH around 6 PM tonight. With respect to cement volumes, some initial calculations we've considered (based on volumes returned, etc.) estimate TOC around 200' which would require +/- 95 bbls of slurry to top up. As a contingency, we are in the process of mobilizing enough cement and hot mix water to mix and pump +/- 400 bbls of slurry. Obviously, well have to run tubing, see where we tag up, and estimate volumes accordingly prior to pumping a top job. Please advise if you require any additional information.

They did have dye in the spacer which he said was 100 bbl ahead of the cement and it is reported that they saw the dye. He has 100' of tubing (not sure what size) on rig and stated his intention to RIH to the base of the conductor. I informed him that simply going to the conductor shoe was not sufficient and he will let the rig know to mobilize more tubing. Darrell Green is on the rig and I asked Chuck to have him contact the Inspectors so one could be there if possible. I have asked Chuck to provide me more information regarding the actual job. It appears they pumped nearly 1400 bbls of cement via a normal plug job to cement 13-3/8" x 16". I understood they did have some sort of caliper, however I don't know that information.

On the 407, the 7" casing depth (7638') does not agree with the depth for the long string scenario (7713') or the contingency scenario (7012'). Would you please reconcile? 2. On the "Operational Considerations" page ... a. A gas gradient of 0.1 psi/ft is specified in the regulations for calculating MASP. Although the 0.11 gradient you use is not much different. Using the 0.1 factor gives a MASP of 3170 psi. b. Although the 7.71 EMW value used as the maximum expected formation pressure in the surface 2/23/2007 8:50 AM RE: Aklaq #6 • • hole is based on the pore pressure analysis, it is interesting that asub-normal value is used. It would seem that a water gradient would be appropriate. 3. Where MASP is calculated, experiencing a fracture at the last casing shoe during potential well control operations is used to limit the calculation. While it may be operationally valid to consider shoe fracture, the regulations do not consider this event. The value determined using a 0.1 psi/ft gradient helps determine the required BOP pressure rating. 4. Is your 7" cement job planned as a single stage (lead and tail) or a true 2-stage operation using a cementing tool in the string? 5. The cement volume planned for the 5" liner appears "short". I calculate a gauge volume of about 11 bbls using the depth, hole size, liner size and lengths given. Would you please confirm the liner cement volume. 6. Various tubular sizes will be run into the well after surface casing is set and the BOP installed. There is no mention in the procedural text regarding the necessary ram sizes. Could you provide some information as to what ram sizes are available? Will VBRs be employed? Thanks in advance for your reply. Call or message with any questions.

If something is urgent/critical, they will usually call me or (when we have one) the other engineer. Hope this answers your questions. I am in the office for a bit if you would like to call. Tom Maunder, PE AOGCC Alaska Environmental Coordinator wrote, On 1/28/2007 8:31 AM: Tom - I went away on rotation and it appears that this information did not get answered. Our spill plan lists 907-279-1433 for the main number and 907-659-3607 for the North Slope Pager, If this is not correct, please advise. I tried the NS pager, but didn't get an answer. However, it was 12/26, so that might have been the issue. What is your phone number(s)? Specifically who in town is the correct person to receive the notification? Other than the NS number, is there an after hours number in Anchorage? Do you ever get out to the sites? If so, I'm working the mid--end of month rotation.

Thanks in advance, Tom Maunder, PE AOGCC Alaska Environmental Coordinator wrote, On 1/2/2007 8:10 AM: To all concerned: This note confirms the telephone notifications that were made December 26, 2006. On that date there was a small fire in the mud pits of the Akita 63 rig that is mobilizing for the Jacob's Ladder project. The rig was not drilling at the time of the incident. The rig is located on the Veco Yard in Deadhorse Alaska. An incident investigation has been completed by Doyon. The fire is thought to have been associated with a welding incident. A fire watch was on duty and was the first observer. One individual was observed for smoke inhalation but he returned to work without difficulty. No spills were associated with the incident. Once the fire was observed the following actions occurred: 1. Afire notification was made to employees on the rig and in the camp, 2. Workers in the immediate area responded with fire extinguishers, 3. All persons were accounted for and non-essential persons removed from the immediate vicinity of the fire, and 4. The Prudhoe Bay Fire Department response to request for assistance. 5. Agency notifications were made by Anadarko and a report was made to the FPS by the Fire Department. If anyone requires additional information, please contact Thor Kallestad or Barbara VanderWende at 907-242-7133 or 907-771-0325.

ZO AAC 25.035 (h) (1) gives the Commission discretion to approve a BOP equipment variance if the variance provides at least an equally effective means of well control. Electrically powered actuators and controllers are routinely utilized on drilling rigs. If power were to be lost, the choke may be manually controlled or the other available manual controlled choke could be employed. Employing a choke with an electric actuator should not compromise the ability to perform well control operations Your request for a variance to the requirements of 20 AAC 25.035 (H) (i) is granted. Please feel free to contact Tom Maunder at 793-1250 with any questions or comments. Sincerely, John K.

[ts exemplary service record. sets a precedent for high mliability, low maintenance and ease of installation. Pason's [ightweight actuator installs easily, using the rig's standard 110-volt power supply. The actuator's compact l8-inch design 6ts easily in the cramped manifold shack, while its lightweight control box can be wall-mounted in both the manifold shack and doghouse for added con- venience. Cumbersome hydraulic lines and air hoses have been replaced with a single electrical cord, thereby eliminating the potential for freezing or leaking and in so doing, making the unit virtually mainte- nance-free. r ~~`~,E -; ~3 i ` ~ q[ ~~~Y ~ d Y The actuator is designed for use with two and three-inch i/~-turn Willis valves and ties directly into the Electronic Drilling Recorder (EDR), recording choke positions alongside pump and casing pressures. Extensive testing and field installations have proven the dependability of the actuator in critical well control situations.

This permit to drill does not exempt you from obtaining additional permits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. A weekly status report is required from the time the well is spudded until it is suspended or plugged and abandoned. The report should be a generalized synopsis of the week's activities and is exclusively for the Commission's internal use. All dry ditch sample sets submitted to the Commission must be in no greater than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. When providing notice for a representative of the C mission to witness any required test, contact the Commission's petroleum field~in ect rat (907) 659-3607 (pager).

Mudlo~~ing: Surface to T.D. Geologic Summary: Jacob's Ladder Lisburne Prospect targets a collapsed paleokarsted cave fades in the carbonate Pennsylvanian Wahoo Formation of the Lisburne group, as interpreted from 3-D seismic data. Literature suggests that successful rifting which opened the Canada Basin during the early Cretaceous 0132 MY), resulted in uplift of the Barrow Arch and development of an extensive fracture network. This uplift led to widespread erosion and subaerial exposure of previously deposited formations, including Lisburne carbonates. Based on Anadarko's interpretation of seismic data, it is believed that meteoric waters, which were preferentially focused along the fracture network, excavated cave systems in the Lisburne carbonates parallel to major fracture orientations. Data indicate that after continued deposition of sediments and reburial of the Lisburne, the cave systems were eventually unable to support the weight of overburden, and collapsed at 80-90 MY. This collapse resulted in the creation of the proposed Jacob's Ladder Lisburne target reservoir, a brecciated carbonate fades, trapped stratigraphically by tight unkarsted Lisburne carbonates. Generation and migration within of the self sourcing Lisburne Group would have occurred from 60 MY to the present using interbedded shales, the dolomite member of the Alapah Formation or fractures underlying and connected to the collapsed cave system as migration pathways. As this is a new play concept for the North Slope, there are currently no known wells which have penetrated this collapsed cave fades within the Wahoo. The brecciated cave fades could be highly cemented with relatively minor porosity (<10%) and permeability, or could contain cavernous solution channels and voids, as have been observed in other karst plays such as the Dollarhide Field in West Texas.

I have used the information you have provided along with our local knowledge about work in the Arctic. As you know most of the previous work was done quite some time ago and information is not readily available. However, Doug Hupp was able to glean some information from the Alpenglow exploration well. I based the intermediate proposal on this information. One question you asked about was temperature gradient. There aren't any formal gradients developed for that area that I have come across. However, I feel the temperature estimates that I have will be close. Typically, in the Kuparuk and Prudhoe Bay area, a gradient of 2.6/100' below the permafrost to about 7000' TVD works well. Past 7000' TVD a gradient from 2.0 - 2.2/100' works best. For the intermediate and potential liner we used 2.0 deg/100' below the permafrost. At the time of the job we can look at the logging temperatures (either a-line or MWD) and get a better feel for what we will be looking at during the cementing operations. have also not provided any information for the P&A operations. We can work those as they arise, as there is so much uncertainty concerning lengths and depths. On the following pages, I have summarized the primary or controlling factors in each strings designs- t have also included a summary sheet based on our CemCADE simulations. At the time of the jobs we can put actual parameters (mud weights, ECDs, temperatures, etc) into the models to assure we can achieve your objectives. For the intermediate cases the lead slurry is an extended slurry used for fill purposes only. We can provide a slurry based on our CemCRETE technology if you decide to place a competent slurry across any of your other targets. If there are any questions concerning these proposals for AFE purposes please contact me at 263-4207 (office) or 748-6900 (cell). I look forward to discussing these proposals with you when you return to Alaska R spectfully, `~' V Michael W.

This will allow for optimum screen performance during drilling operations. It is important to develop a good preventive maintenance schedule which includes replacing the decking rubber before it becomes a performance related issue. • Install XR Magnum screens (84 - 110 mesh). Ensure screens are properly tensioned, per M-I Swaco's best practice suggestions. Spray down new screens with fresh water before operating the shakers. • Set counterweights to 95% (8 G's) for optimum performance. • As fluid shears, screen up as necessary to higher mesh screen sizes. • Ensure jacking system on ALSII or equivalent shakers enables the fluid to flow to the center of the screens, adjust and lock as necessary. De-Silter- • Ensure cuttings trough bypasses shakers, and goes into cuttings ditch. Failure to do so will allow small particles to enter right back into system through the flow line shakers (84 - 110 mesh screens). • Verify that '/2" apexes are installed on all clones. '/" apexes will not make as fine of cut as 3/8" apexes, but due to the fact there is no De-Sander, larger particles will pack off the 3/8" apexes and result in poor performance. • Ensure that Feet of Head gauge is available at the De-Silter, not the pump. • Ensure that De-Silter feed pump can achieve 95' of head. CRITICAL! Changes can be made quickly to the impeller or speed of the pump to improve the head capabilities. Ensure that sufficient spares are located at rig site. These spares would include enough Apexes to install 5/8", '/", or 3/8" assemblies, depending on well formations, fluid rheology, and circulating rates. • Monitor discard, change apexes as necessary to improve solids content in mud (it may be determined that 3/8" apexes can be installed if cuttings in the system happen to be finer than presumed). Centrifuge- • Surface and Intermediate intervals require a greater through put during most operations, which require the centrifuge to run at a lower speed (2,500 rpm). This setting allows the centrifuge to process more fluid and discharge more cuttings. The only draw back of the lower rpm's, is the cut point is reduce from 3 - 6 micron cut, to approximately 6 - 10 micron. Swaco recommends and stands behind the suggestion to run the centrifuge at the lower speeds during the upper sections of hole. General- • Proper apex size on the desilter during this section will greatly improve the performance of the centrifuge and overall solids control performance of pit system. Drilling conditions may dictate the several apex adjustments; close supervision of mud cleaner will be highly rewarded. Location North Slope Alaska Confidential 5 Date: June 21, 2006 • • ~w~ Anadarko M~ SWQC,'~ , . .~~_ Jacobs Ladder #1 Surface Interval Overview . Surface to 3,500' MD Lithology through this zone is a composite of small gravel in the upper intervals with a grading downward to sand, clay, and some siltstone in the lower zones of this interval. Based upon work done on previous wells and to reduce haul-off costs a KCI/Klagard spud mud is recommended for the surface interval. Initial viscosities of 250 - 300 sec/qt should be used through the permafrost. Rheology should be maintained at the higher end of the recommendations throughout the interval due to the length of this interval. Hydrates may be an issue. Precautions may need to be taken for such an occurrence. The surface interval will enlarged to 16" with a hole opener before the 13.375" surface casing is run into the hole. Surface Interval Drilling Concerns: - Use as cold of water as possible for the initial make-up and for additions made to the mud system during the surface drilling operations to help prevent permafrost thawing. - Large gravel sizes can cause hole-cleaning problems. If larger than normal gravel is encountered be prepared to increase funnel viscosity to 300 sec/qt. Have Gelex available for an immediate response to this issue. - Sticky clays in the permafrost and also in the zone below the permafrost can slow ROP from bit and BHA balling. If needed add SKREENKi_EEN (at 0.5 - 1 %) and Nut Plug (as allowed by MWD tools) to minimize clay to metal sticking. - Swabbing in the clays may also be a problem. Maintain or slightly increase mud weight (.1 ppg) and continue additions of SKREErvKLEErv at 7 to 15 gallons per hour and wiper runs through these intervals may both be necessary to clear the wellbore of the problem clays. - Hydrates may be encountered beneath the permafrost. Increase mud weights to 9.4 - 9.6 ppg by 1,500' to help control the hydrates. Observe good drilling practices to determine severity of any influx and weight up as needed to maintain proper well control. See the "Hydrate Issues" enclosure. - To help ensure good hole integrity maintain the YP at above 20 - 25 prior to cementing the casing. Have water on hand to ensure the desired rheologies can be achieved. Location North Slope Alaska Confidential 6 Date: June 21, 2006 • Anadarko M~ .~7vvAV~-~ Jacobs Ladder #1 Surface Interval Operations Recommendations: 1. Spud mud will be mixed on the rig or delivered from the MI mud plant once the rig is spotted over the well. For the first batch (100 - 200 bbls) of fluid mixed add caustic or KOH and 2.5 ppb M-I Gel to the first batch of make-up water and allow the gel to hydrate as long as is possible prior to mixing the other products. Use as cold of water as possible for the initial make-up and for additions made to the mud system during the surface drilling operations. 2. Just prior to spud, add Gelex, as needed, to raise viscosity to 250 - 300 sec/gt. Maintain rheology as required using M-I Gel/telex to clean the hole. Make sure to maintain rheologies at the high end of the recommended parameters to ensure wellbore stability below the permafrost. 3. Drill ahead maintaining volume with additions of water. 4. Control the flow rates at 450 - 550 gpm in the upper interval to avoid washing out the conductor shoe. Target 650+ gpm in the remainder of the hole. Sustained drill rates above 100 fph should be monitored closely for hole cleaning issues if the flowrate cannot be maintained at 650+ gpm. 5. Run all solids control equipment as recommended in the solids control portion of this program. 6. If deemed necessary add Lecithin at 2 ppb prior to drilling in the hydrate zone at the base of the permafrost (1,956' TVD) and maintain this concentration to TD. Additions of Desco CF may be needed to control rheology after the Lecithin additions. 7. Lower API fluid loss with Drispac UL as needed to maintain hole stability. 8. Additions of MIX II may be needed while drilling through the Ugnu sands. Consult with geologist to determine if the Ugnu is fine grain or coarse grained and treat the fluid with MIX II to reduce relative permeability as needed. 9. To control rheology, additions of Desco CF may be needed. 10. Add SKREENKLEEN (at 0.5 - 1%) and Nut Plug (at 15 ppb) to reduce bit balling in the clay sections if needed. 11. After drilling the surface interval with a 12.25" bit, open hole logs will be run. The hole will then be opened up to 16" prior to running the 13.375" casing. 12. Maintain the fluid rheology while enlarging the hole. Watch for hole cleaning issues and adjust the fluid and drilling procedures to optimize the cleanup of the interval. 13. Allow surface mud volumes to fall during the later stage of the hole opening run to minimize waste fluid disposal costs. To help ensure good hole integrity maintain the YP at above 20 - 25 prior to cementing the casing. 14. Upon drill-out of the surface casing shoe, treat any cement returns with SAPP, Bicarb, and PH-6 as needed.

Swaco recommends and stands behind the suggestion to run the centrifuge at the lower speeds during the upper sections of hole. • Refer to mud man for solids information to determine speed and feed rate of centrifuge. • Continual processing at low feed rates will yield better results than shutting centrifuge down and starting it up. Slow feed rate down to maintain an acceptable weight if needed. General- Inhibitive mud systems improve the solids control efficiency of any rig. Fine solids will still accumulate as drilling progresses. Do not turn off centrifuge or fines solids will catch you off guard in this section. Location North Slope Alaska Confidential 11 Date: June 21, 2006 • r Anadarko MI SWA~,'~ ~ Jacobs Ladder #1 Intermediate Interval Overview This interval will be drilled using a 12.25" bit. Conditioned mud from the surface interval will be used for this interval. The intermediate interval will TD at a depth of +/-11,000' MD. The 9.625" intermediate string will then be set prior to drilling the production interval. Watch for indications of over pressure and treat the mud accordingly. Intermediate Interval Drilling Concerns: - Coals and clays may change the rheology of the mud - be prepared to treat the mud should this occur. - Mud weights will need to be increased and Resinex/Soltex additions completed prior to drilling into the HRZ/Kalubik intervals Intermediate Interval Operations 1. Conditioned mud from the surface interval or new fluid delivered from the MI Mud plant in Alpine will be used to make up the KCUKLAGARD fluid for this interval. Conditioned mud should be centrifuged as needed to achieve the desired drill out weight of 9.4 - 9.5 ppg if possible. 2. Drill out the cement and the shoe treating the cement contaminated mud with SAPP, Desco CF, and Spersene CF. 3. Interval pore pressures may vary with the planned mud weight requirement of approximately 9.4 - 9.5 ppg at the 12.25" casing shoe to 10.5 - 10.6 ppg within 100' TVD of the HRZ. Pressure uncertainty exists, and pore pressures could be higher or lower. Any fluid weight adjustments should be performed in 0.1 - 0.2 ppg increments using MI Barite or a weighted "spike" fluid. Keep current with mud loggers, directional drillers, and MWD personnel on gas readings, oil shows, and depths for weight up needs. 4. Prior to drilling into the shale add Resinex and Soltex at 4 ppb each to lower the fluid loss to 4 - 5 cc. 5. Chlorides will be maintained at 28,000 - 32,000 throughout the interval. 6. Maintain Klagard concentrations at 8 ppb while drilling. 7. Run weighted high viscosity sweeps if increases, above normal expected, are seen for ECD's, torque, or drag.

Ensure screens are properly tensioned, per M-I Swaco's best practice suggestions. Spray down new screens with fresh water before operating the shakers. • Set counterweights to 90% (7.8 G's) for optimum performance. • As fluid shears, screen up as necessary to higher mesh screen sizes. 210 mesh is optimum to reduce sand sized particles. • Ensure jacking system on ALSII or equivalent shakers enables the fluid to flow to the center of the screens, adjust and lock as necessary. De-Silter- • Ensure cuttings trough bypasses shakers, and goes into cuttings ditch. Failure to do so will allow small particles to enter right back into system through the flow line shakers (84-110 mesh screens). • Install 3/8" Apexes. • Ensure that Feet of Head gauge is available at the De-Silter, not the pump. • Ensure that De-Silter feed pump can achieve 95' of head. CRITICAL! • Monitor discard, change apexes as necessary to improve solids content in mud (it may be determined that 3/8" apexes can be installed if cuttings in the system happen to be finer than presumed). • Discard should be 2 - 3 ppg over feed weight. Centrifuge- • Production intervals generally call fora "high-speed" centrifuge, which is rotating at approximately 3,200 rpm's. This allows the centrifuge to make the 3 - 6 micron cut, and eliminate a percentage of the "ultra fine" cuttings from the fluid. Through put must be decreased while running the centrifuge at 3,200 rpm's, since there is a greater risk of "packing ofF' the centrifuge back drive and auger. Swaco would also suggest installation of amp meter on the back drive motor which will allow the operators to monitor the feed rates by knowing how much torque the back drive motor is receiving while trying to discharge the cuttings. • Refer to mud man for solids information to determine speed and feed rate of centrifuge. • Continual processing at low feed rates will yield better results than shutting centrifuge down and starting it up. Slow feed rate down to maintain an acceptable weight if needed. Location North Slope Alaska Confidential 14 Date: June 21, 2006 Anadarko Mi SWACQ -~e -~~ `Jacobs Ladder #1 Production Interval Objectives The production interval will be drilled using a 8.5" bit to a TD of 12,400' MD. Production Interval Drilling Considerations - Lithology for this interval is expected to be typical of this region. - Maintain mud weight at 10.5 - 10.6 ppg, or as needed for well control, and ensure that theology is optimized. Monitor for any fluid losses and flow back closely. - Lost Circulation. Monitor pit volumes and observe good drilling practices to reduce the chance of inducing losses. See the enclosed lost circulation recommendations for suggestions on treating any losses. - Fluid deliveries, fluid transfers, and cuttings disposal issues will be tracked on a daily basis. Production Interval Considerations - Drill ahead watching for wellbore instability, lost circulation, or pressured formation problems. Any fluid weight adjustments should be performed in 0.1- 0.2 ppg increments. - Have LCM on hand and monitor pit volumes closely. Expect and plan for losses. See the enclosed "Lost Circulation Recommendations" for suggestions on treating any losses. - Although lubricants are not expected to be needed, add lubricants if needed but do not exceed 3% v/v total without careful consideration and evaluation of drilling parameters that may be affecting the hole cleaning. Add lubricants as per the enclosed lubricant treatment decision tree. - Monitor and record drilling parameters on each connection. - Upon reaching TD watch the bottoms-up cuttings closely. If the well does not readily cleanup or if there is any excess of torque, drag, pick-up or slack-off weights pump a second high viscosity sweep and observe bottoms up again. Location North Slope Alaska Confidential 15 Date: June 21, 2006 r~ ~~ Anadarko M~ SWaG'~ ~ Jacobs. Ladder #1 Production Interval Operations: 1. Ensure that the fluid properties are maintained to provide the best possible hole cleaning. 2. Maintain flow rates above 350 if possible to ensure hole cleaning. Reduce pump rates immediately if packing off occurs. Pump high viscosity sweeps and ream carefully to clean the hole before proceeding with further drilling. High Viscosity Sweep Formula 25 bbls of whole mud Duovis - 0.5 - 1 ppb (allow to shear for LSRV @ 60,000 - 80,000) 3. Drill ahead. Maintain the rheological properties as low as possible while still maintaining good hole cleaning to minimize inducing losses in this interval. 4. Maintain filter cake thickness as thin as practical to help logging and testing operations. 5. Watch for lost circulation. Treat for losses as per the recommended treatment enclosure. Use calcium carbonate for the initial treatment of losses and only resort to the use of the MIX II product after consulting with the drilling engineer. 6. Drill ahead watching for wellbore instability problems. Any fluid weight adjustments should be performed in 0.1 ppg increments using Sodium Chloride. 7. Add S-325 (CaC03) to ensure that the 35 ppb is maintained while drilling. 8. Add any lubricants as per the "Lubricant Treatment Decision Tree". 9. Upon reaching TD watch the bottoms-up cuttings closely. If the well does not readily cleanup or if there are any excess of torque, drag, pick-up or slack-off weights pump a second high viscosity sweep and observe bottoms up again. 10.

Corporation 2 September 15096-02.Oa/06-130 • Jacob's Ladder Exploration Program ~ ~ Plan of Operations 2.0 Overview and Timetable Anadarko Petroleum Corporation (Anadazko) proposes amulti-year drilling and .testing exploration program in areawide leases located on the Arctic Coastal Plain about 20 miles southeast of Prudhoe Bay in the Jacob's Ladder Unit (Figure 1). For the 2006/2007 winter season, Anadarko proposes to drill one exploratory well at Jacob's Ladder Unit C. The exploration drillsite will be connected via snow/ice roads to existing North Slope infrastructure. The proposed winter road alignments and well locations are. provided in Sections 3.0 and 4.0 as well as Figures 2 and 3. Road and ice pad construction will begin as early as December 2006, pending land use and tundra travel permit approvals and when weather conditions allow. Current plans are to plug and abandon the well in accordance with AOGCC regulations at the end of the 2006/2007 season or tundra closing depending on requirements of the ODPCP. Tested or completed wells will remain temporarily suspended in place until final plans are made for appraisal and development. 3.0 Drillsite Access There aze two. proposed access route alternatives. Their use is dependent upon ice conditions and access privileges. One route would begin near the Prudhoe Bay Unit (PBU) Drillsite (DS) 16 and the other would begin neaz Deadhorse at Veco's backyard and progress southeast where they converge with the main access route to the exploration drillsite (Figure 2). Using permitted freshwater sources (Figure 7) and existing packed snow as the road base, the road (Figure 4) and drill pads (Figure 5) would be built up until sufficient strength and thickness are obtained to support project equipment loads. Ice chips may be used, as needed, if weather or construction conditions warrant their use. Approximately 16 to 20 miles of winter access and spur roads would be constructed in support of the exploration well. Access to the existing operating field infrastructure via the Dalton Highway is controlled at security checkpoints. Prudhoe Bay/Deadhorse Security will control access to Anadarko sites. Access must be granted by Anadarko. Cross country travelers, including subsistence hunters, may travel across and on the road system, however, the well site will be closed to ensure public and. worker safety. Visitors to the site must participate in a safety briefing and be escorted while on the work site. Firearms will be prohibited on the well site, except for the designated bear hazer. Anadarko will provide emergency assistance, including protection from severe weather, as necessary to ensure human safety. Signs will be posted at the well site to alert visitors that they have. approached a secure work site. The sign(s). will include Inupiat and English instructions on how to contact a designated Anadarko field representative for access procedures to the well site: 4.0 Drillsite and Locations The well pad will be constructed of ice and be approximately 600 ft x 600 ft. The pad will be connected to the access road system by short spur snow roads to avoid through traffic on the ice pad. See Figures 5-for typical drill site layouts for drilling and Figure 6 for (future) well testing operations.

Access roads and the drillsite pads will be built using a combination of existing snow along the route, freshwater pumped from lakes along the roads, and freshwater ice chips from permitted sources. In addition, fresh water is needed for road and pad maintenance and drilling operations. A maximum of approximately 283,000 gallons per day (gpd) will be required for road and pad construction and road maintenance (90 days). A maximum of approximately 10,500 gallons per day will be required during the drilling operations (60 days). A maximum of approximately 26 million (MM) gallons (79 acre feet/year [ACY]) of water will be required to support the project. Anadarko .will use a portable camp for its exploration activities. The camp will house approximately 65 persons. Potable water will be trucked in and geeywater backhauled to an approved disposal facility. 6.0 Drilling and Testing The planned well. bore design will be similar to that employed in previous North Slope exploration wells. The actual well bore design is subject to' approval by the AOGCC in its drilling permit. Due to the exploratory nature of the well, nearly all information regarding the downhole aspects of the wells will be confidential. Production tests will be performed, as needed, after production casing is set. Testing will occur once the drilling rig has moved on to its next location. Testing may include extended flow periods to determine the productivity of the well. 6.1 Non-Drilling Wastes Solid, non-burnable waste, including scrap metal, banding material, etc., will be deposited in large dumpsters located at the site as needed for each waste classification. These containers will be back-hauled appropriately to the NSB landfill at Prudhoe Bay. The food waste that can -attract wildlife will either-be hauled vn a-daily basis to asecured-disposal site or-stored in an enclosed convex container awaiting transport. To reduce the amount of waste that must be back-hauled from the drilling location, all solid, burnable waste will either be incinerated onsite Madarko Petroleum Corporation 4 September 2006 15096-02.05/06-130 • Jacob's Ladder Exploration Program ~ Plan of Operations in accordance with ADEC regulations or back-hauled to an approved upland facility. Any resulting ash will beback-hauled to the NSBlandfill. All potable water will be hauled in and all greywater will be backhauled to an approved facility. 6.2 Disposal of Drilling Wastes Water based drilling mud will be used. Mud contains additives to maintain desired drilling fluid properties and density. Excess drilling mud that cannot be reused (Figure 8) will be transported to an approved Class II injection well in the Prudhoe Bay or Kuparuk infrastructure for disposal or potentially disposed of via AOGCC approved annular injection. As the drill cuttings exit the drilling rig, they will be collected in steel cuttings containers. Drill cuttings can be processed in several ways. In order of expected plans, the cuttings will be: 1) transported to a certified processing and disposal facility, via vacuum or super sucker truck to an approved injection well in the Prudhoe Bay or Kuparuk infrastructure and/or potentially disposed down an AOGCC approved annular injection, or 2) placed in an ADEC approved temporary drilling waste storage cuttings area. As toxicity levels allow, drill. cuttings that are placed in the temporary waste storage area will be transported to the Oxbow Landfill (NSB) at Prudhoe Bay for disposal. 6.3 Disposal of Produced Fluids Produced fluids will pass through a flow meter and an adequately sized separator system to prevent oil carryover into the gas stream. All fluids will be held in tanks until the testing is completed. After testing, the fluids will be injected back into formation or hauled to Prudhoe Bay or Kuparuk and processed through these facilities. 6.4 Air Emission Sources of air emissions are from the operation of rig .engines,. camp generator engines, steam generators, mobile non-road engine and construction equipment, waste oil burners, hot-air heaters, light plants, incinerators, and well test flaring equipment. Anadarko will submit an application to ADEC for coverage under Minor General Permit (MGPl) for Oil and Gas Drilling Rigs. Anadarko proposes to use fuel oil with 1,900 ppm sulfur by weight content. 6.5 Historic, Archaeological, and Cultural Resources Cultural resources studies for site clearance were conducted in 2003 and 2006 to assess any known sites, and to locate unknown sites. The study had. two components: records review and in-field survey. The records review included the Alaska Heritage Resources Survey (ARKS) database, maintained by the Office of History and Archeology within ADNR; and the Traditional Land Use Inventory (TtiUl) database, maintained by the NSB. There is one Native Allotment owner in the Jacob's Ladder Unit located in Township SN, Range 18E, Sections 20, 21, 28 and 29; Herbert Ahkivgak of Barrow, AIaska. Mr. Ahkivgak and his wife have accompanied Anadarko representatives in. the area and have provided traditional knowledge information. Anadarko Petroleum Corporation 5 September 2006 15096-02.05/06-130 • ~ Jacob's Ladder Exploration Program Plan of Operations No previously-recorded AHRS sites will be affected by any of the proposed exploration activities. A report of these findings will be submitted to the ADNR Office of History and Archeology. 6.6 Verfical Seismic Profiles Vertical seismic profiles (VSPs) may be acquired using up to two vibroseis trucks. These trucks are off-road vehicles approved for tundra travel. The operation typically requires the vibroseis units to move along a dine starting at the well bore and stop at. varying distances from the well out to a total distance dependent on-the depth of the well and the magnitude of any deviation of the well. For this project the vibroseis units will probably remain on the ice pads or roads; however, if the trucks do leave a pad, all VSP lines will lie within a 2-mile radius of the surface location of the well or along the road. 7.0 Well Abandonment and Site Closure Upon completion of drilling and evaluation operations, any remaining debris will be hauled to an approved disposal site. Spills or ice/snow contamination occurring on the ice pads or roads will be chipped or scraped back for pick up and either annular disposed of at a certified disposal facility or, as toxicity levels allow, hauled to the Oxbow Landfill (NSB) at Prudhoe Bay. Spill reports will be filed with ADEC, ADNR, and the NSB. All unsuccessful wells will be plugged and abandoned in accordance with applicable AOGCC regulations. Following the seasonal thaw in the spring, the route and well sites will be inspected. Debris will be collected and back hauled for disposal. Final site closure will be approved by ADNR (Land ,Manager) representatives after a site visit the following summer. 8.0 Contingency Plans 8.7 Wildlife Access Wildlife that could be in the area during the winter include: owls, ravens, arctic foxes, and polar bears. Grizzly bears also inhabit the coastal region, but it is•unlikely they will still be active during the winter season. Project personnel will be instructed not to feed or cause attraction of wildlife at the drillsite or on the ice roads. Although encounters with grizzly and polar bears are not common, Anadarko and its contractors will exercise caution while establishing the transportation route and watch for bear sign. )f bear sign is observed or a den identified, the USFWS and the Alaska Department of Fish and Game (ADF&G) will be notified and the transportation route altered to avoid any disturbance. Food and food waste will be kept inside buildings or containers that minimize odors. Hazardous materials will be kept in drums or other secure containers. Building and drill pad layouts will be designed to maximize visibility and minimise potential azeas that a bear could crawl into or otherwise be hidden- from view. Any sightings will be immediately reported to the site supervisor and the personnel in the azea warned of the location _ _ ___of the-bear. Anadarko Petroleum Corporation 6 September 2006 15096-02.05/06-130 • ~ Jacob's Ladder Exploration Program ~ Plan of Operations A comprehensive Bear Avoidance Encounter/Interaction Plan, filed with the USFWS and ADF&G provides operational, monitoring and reporting guidance for field operations. Anadazko will request USFWS and ADF&G to provide known den locations prior to access road and well pad construction. If appropriate, Anadarko will consider using a local subsistence representative to provide guidance on how to avoid and min;m;tee interactions with subsistence resources and their use. 8.2 Oil Discharge Prevention and Contingency Plan An approved Oil Dischazge Prevention and Contingency Plan (ODPCP) with individual well site addenda will be kept on site at all times to provide guidance for controlling and cleaning up any accidental discharges of fuel, lubricants, or produced fluids. Information related to immediate response actions, receiving environments, spill cleanup .mobilization, response times, and source control is found in the ODPCP. Anadarko is a current member of Alaska Clean Seas response cooperative. 8.3 Spill Prevention Control and Countermeasures Plans The drilling contractor has a Spill Prevention Control Countermeasures (SPCC) plan for the drilling rig and their fuel storage facilities associated with drilling operations. The well testing company has an SPCC plan for their testing tanks. 9.0 Communications and Supervision Anadarko designated representatives will be on site at all times during operations. Twenty- four hour phone service will be available at the drilling camp.

The information should answer your questions and provide clarification to our assessment of shallow sand salinities and shallow gas hazard identification. The information included in the Shallow Sand Study depicts our assessment of zonal salinities and also includes a tabulation of the analysis by depth. The Shallow Gas Hazard Evaluation includes an identification of the seismic data that was analyzed in conjunction with the other well specific review that was conducted in our efforts to assess the potential to encounter shallow gas hazards. Please note that both 2D and 3D data sets were reviewed and our analysis of the same confirms our assessment from offset well information that no specific shallow hazards are evident. If you have any questions or require additional information, please contact me at (907) 273-6302. Sincerely, ANADARKO PETROLEUM CORPORATION y T pso Drilling Operations Manager enclosures • • Addendum to Jacob's Ladder C location shallow hazards report The purpose of this addendum is to clarify Anadarko's shallow hazard assessment particularly with regard to data seismic quality. The report states there were 3 seismic data sets utilized in the shallow hazard assessment. This addendum will hopefully clarify these specific sets and the data quality and expand how they compare to other seismic datasets regionally on the North Slope. The primary 2D data set used was acquired in the early 1990's by Western Geophysical. It is fair to good quality in the shallow section and images northerly dipping strata subcropping at the surface. The 2D grid is an irregular 2 mile grid of data. Fortunately line WG92-101 was shot over the C location and ties the Lake Federal 79 well. The line is of sufficient quality to image shallow gas sand if present and thick enough. The reason there does not appear to be any significant anomalies is most likely due to no trapping configuration and the section subcrops to the surface to the south. The primary 3D control used for the shallow hazard assessment was the Catamount 3D survey shot for BP in 1996. One benefits of the narrow azimuth acquisition technique is the preservation of some shallow data particularly in the inline direction. Looking at the cross line oriented seismic section A-A' supplied in the report illustrates the shallow control. There are windows of extremely shallow data parallel to inlines covering approximately 700 feet followed by a gap of approximately 1300 feet repeated throughout the survey. The data quality remains fair in the extremely shallow section of the inline areas of coverage. These inline areas of coverage augment our 2d data set providing more control in the section above 500 milliseconds or 2500 feet. Data coverage below 500 milliseconds or 2500 feet improves significantly. This is just above the depth of the base of the hydrate stability zone of approximately 3000. If shallow free gas is trapped it would most likely be below 3000 feet. In this zone the data quality and coverage is adequate to image a shallow amplitude anomaly. Shallow amplitude mapping included in the report illustrate no anomalous amplitudes were detected at the proposed well location. For completeness APC reviewed the Endeavour 3D and used it mainly for assessing if any shallow velocity anomalies were present, none were detected in the shallow section at the proposed location. This corroborates analysis from the 2D and the Catamount 3D. However the data quality of the Endeavor survey in the shallow section is problematic. Overall Anadarko has used the best available seismic data to assess the shallow hazards for Jacob's Ladder C location. There are no indications a shallow gas hazard exists at the location. Seismic data quality in the area is similar to other data set on the north slope used to assess shallow hazards for other drilling locations. • ~~ ~J Jacob's Ladder Shallow Gas Hazard Evaluation Summary: Offset Well data and seismic data indicate there is a low risk for encountering shallow gas hazards in the Jacob's Ladder C well. Data base: Several wells are in the vicinity of the Jacob's Ladder C (C location) well location. The closest well to the C location is the Lake Federa179 well, 7000' to the north-northeast. Additionally, the Kad River well is 18,500 feet to the northeast and the Kadler State 15- 9-161ies 38,000 feet to the west-northwest and the Mikkelsen Bay State 13-9-19 well lies 80,000 feet to the northeast. 3 seismic datasets were analyzed for potential shallow gas hazards: 1. non-uniform 3 x 3 mile grid of 2D data 2. Catamount 3D survey shot by BP in 1996 3. Endeavour 3D survey shot by Anadarko in 2001 Seismic data coverage and wells are illustrated on the location map, figure 1. Stratigraphy and Log Indicators: In the local Jacob's Ladder area, the interval from zero to approximately 5,400', Measured Depth (MD) in the Lake Federa179 well, consists of gravel, conglomerate, sand, silt, and shale with very minor amounts of lignite and coal from the Brookian Megasequence. The strata were deposited at a very low angle and have since undergone very little deformation. Correlation and mapping of markers within this interval in nearby wells and seismic indicate that there is approximately 2° north dip. The following wells are hard evidence to support the conclusion there is low risk for encountering shallow gas in the vicinity of Jacob's Ladder C well: Lake Federa179 well, 7000' to the north-northeast Kad River well is 18,500 feet to the northeast Kadler State 15-9-161ies 38,000 feet to the west-northwest Mikkelsen Bay State 13-9-19 well lies 80,000 feet to the northeast All these wells encountered minor amounts of methane in the shallow section and had no shallow gas hazard drilling problems. Please refer to the location map to see the relative placement of the wells and the proposed Jacob's Ladder C location. Wells mentioned above indicate the base of permafrost is approximately 1900 feet in the area. Please see x-section B-B', figure 2. • • From 0' MD to 5400' MD in the Lake Federal 79 well a maximum of 30 units of total gas were recorded at a depth of 3050' MD. Lithology logs indicate this interval is a mixture of gravel, sand and shale with minor amounts of coal. The gas is interpreted to be low concentration biogenic methane. There are no reported oil shows in the shallow section. No significant problems or conditions were encountered in nearby wells. No indication of hydrates have been reported in the area however regional work indicates the theoretical base of the hydrate stability zone in the Lake federa179 well would be approximately 3018 feet md. Approximately the same depths, temperatures and pressure regime are anticipated at the Jacob's Ladder C location. Seismic Indicators: As mentioned in the database section, three seismic datasets were analyzed for potential shallow gas hazards. Key displays included in this report are from the following seismic data: 2D line WG92-101 (ties the Lake Federa179 to Jacob's Ladder C location, figure 3 Catamount 3D survey shot by BP in 1996, figures 4-6 Endeavour 3D survey shot by Anadarko in 2001, figure 7 Seismic data coverage is illustrated on the location map, figure 1. The 2D data renders the best image of the shallow section but obviously coverage is problematic beyond the 2D plane. The Catamount 3D data set was acquired by BP as an exploration 3D and has a natural bin size of 330' by 110'. The narrow azimuth inline parallel acquisition technique yields good to fair data quality in the shallow section up to 500 milliseconds, approximately -2700'ss and fair to poor data with coverage gaps from 500 milliseconds to datum, sea level. Anadarko has access to pre-stack time migrated data for the shallow gas hazard assessment. The Endeavour 3D dataset was acquired in a cross spread configuration with a 55' bin size. The target depth for the survey design was 7,000' to 10,000' depth range. Shallow data is poor quality however Anadarko has access to velocity data which was examined for shallow gas hazards. Seismic line WG92-101, figure 3, trends in asouthwest-northeast direction. The shallow section dips to the north at 2°. This 2D line ties the Lake Federal 79 well to the proposed Jacobs Ladder C location and illustrates the north-dipping shallow reflection package that subcrops to the south. The Green horizon tie the base permafrost at the Lake Federa179 well and demonstrates the regional dipping reflections and the subcrop. Interestingly, well data indicate the base permafrost is fairly flat lying and therefore cuts across the dipping stratal boundaries. There are subtle flat lying reflections that may represent the base permafrost, see events indicated by arrows in figure 3. These flat lying events are not coherent enough for mapping. Significantly, there are no indications of high amplitude events associated with this interface that could warn of a potential shallow gas hazard. This could be due to a breach in the sealing capacity of the permafrost thus allowing any gas to escape to the surface via the unconsolidated gravels i • if there was any significant gas in the shallow section. Please note the green horizon is interpreted to subcrop to the south Further, there is no structural closure, nosing or faulting noted to act as potential traps. Previous work had identified the theoretical base of the hydrate stability zone to be approximately 3000 feet in the Jacob's Ladder area. Free gas could form at the base of the hydrate layer and could be a potential drilling hazard. No hydrates have been observed in the area however a shallow reflection was correlated to assess if any high amplitude events are at or near the proposed drilling location. A +/-30 millisecond windowed amplitude attribute map extracted along the shallow horizon, Base Hydrate Stability zone as picked in the Lake Federa179 well indicates an area of elevated amplitude occurs primarily west of the proposed C location. Please refer to figure 4 to review the mapped amplitude and shallow structure and figure 5 for a representative arbitrary 3D seismic line through existing wells and proposed C location. Both the map and seismic line illustrate the C location has not been placed near a high amplitude anomaly. Although the amplitude is elevated along this horizon to the west of the C location the overall level of anomalous amplitude is more than 2 times lower in magnitude than recorded amplitudes deeper in the section. A time slice with a 60 millisecond window designed to paxallel the base of the hydrate stability zone as interpreted in the Lake Federal 79 well shows similax results to the mapped horizon, Figure 6. No anomalous amplitude anomalies were noted at the C location. RMS velocities were reviewed on the Endeavour 3D survey and an example line is included for reference, Figure 7. No anomalous velocity anomalies are detected near the proposed Jacob's Ladder C location. Summary: Offset wells had very minor amount of gas in the shallow section and there were no noted shallow gas drilling hazard conditions in the wells. No anomalously bright amplitudes were observed at the proposed C location and no other indirect indications of shallow gas (velocity sags, "chimneys," frequency shadow, etc.) were noted. Interpretation of the seismic data suggests very low potential for shallow gas drilling hazards at proposed C location. The nearest amplitude anomalies to the west, are weak in absolute terms and do not appear to extend eastward toward the C location. The combined interpretation of offset well data and seismic data indicate there is a low risk for encountering shallow gas hazards in the Jacob's Ladder C well. • i -G' j s -- ~ __ _ ~ o ~'' ~ `~ ~: ~ ~ ~~ ~ -~ ~i,, , I /h' ,!`• W ~ - , c5' 1 / , ~ :.

D. Kilgore Anadarko Petroleum A study has been undertaken to understand the shallow lithologies in the'planned Jacob's Ladder well and to estimate the salinities of these sediments. The purpose of this study is to determine the proper casing programs to use in upcoming wells that v~~ill protect fresh water aquifers if they exist. Well logs from the Kad River # 1 well were analyzed to determine sandy intervals and the salinity of these sands. The sands in this offset well appear to be saline with total dissolved solids, TDS, approaching 22,000 ppm. Permafrost is apparent above 2010 feet. The Kad River #1 wireline logs and an analysis of those logs are displayed in Figure-l. Track-1 contains depth and the borehole geometry from the caliper log. Track-2 contains the Gamma Ray, SP, and Caliper measurements plus abad-hole flag. Track•-3 contains the resistivity measurement curves. Track-4 contains the density measurement, RH:OB. Track-5 contains the sonic measurement, DT. Track-6 contains the clay volume analysis, VSH. Track-7 contains the resistivity of water calculated from resistivity and SP. Track-8 contains analysis notes and explanations. CLAY VOLUMES & POROSITIES Clay volumes were calculated from the gamma-ray where available. The density was logged over the entire bore-hole and was used for porosity calculations. Th.e bore hole is washed out above 2375 and clay volume is invalid above this depth. Porosity is unreliable above this depth as the sediments are partially or completely frozen. The following; algorithms were used to obtain clay volume, VCL, from the gamma ray and porosity, ~ , from the density.

In this technique it is assumed that all sands are 100% water bearing and that no excess conductivity from the shales in the system is present and there are no hydrocarbons. The Archie coefficients were used for values of `a' and `m' (i.e.: a=1 and m=2). The temperature gradient was taken from the bottom hole temperature measured by the wireline tools. All RWA values are converted to 75° F for easy comparison. Salinities have been converted to total dissolved solids, TDS, in units of ppm at 75°F. Rwl ~m Rwa=a Examination of the RWA curves in Figure-1 reveals a highly unstable RWA_SP but a more stable RWA_ARCH from the resistivity analysis. Low spikes are present on the RWA_ARCH that are caused by borehole washouts and depth mismatches between the density measurement, RHOB, and the resistivity measurement. Pickett plots were made to determine the RW values in these two sand packages. RWA analysis using the picket plots gave Rw values of .275 @ 75 DEGF in the 2700 foot sands, Figure-2 and .229 @ 75 DEGF in the 3100 foot sands, Figure-3. These values equate to total dissolved solids, TDS, of approximately 22,000 ppm in the 2700 foot sands and 28,000 ppm in the 3000 foot sands. Salinity estimates from the SP was erratic and a good shale baseline was difficult making the analysis from this method unstable. The erroneous spikes present on the RWA_ARCH Pickett plot were ignored in the analysis and are highlighted in red in Figure 2 & 3. The shaley character of these sands violates the assumption that there are no clay effects in the RWA equation. The extra clay content causes this RWA method to under estimate the TDS values in these sands. • • Figure 2 PICKETT PLOT 2700 foot SANDS (2.65-RHO_COR)/1.65 vs. RT LOG Crossplot Well: KAD RIVER #1 Range: All of Well Filter: DEPTH>2650 & DEPTH < 2850 & ^BADHOLE & VSH<.25 0 196 ~ 196 ~ ;~,~ ~.

Two methods were available for estimating RWA, RW from the resistivity and density curves, ILD and RHOB, and RW from the SP deflections. Two sand packages were identified at 2700 and 3000 feet. The SP was examined and found to contain spurious deflections that do not correlate well with the gamma ray, GR, Figure-2. The SP noise may be caused by electrical noise on the rig but was deemed to be unstable for accurate RWA computations. The ILD & RHOB were used to calculate porosity and then RWA using the formula given below. In this technique it is assumed that all sands are 100% water bearing and that shale effects are absent. Shale free sands do not exist in this well but an estimate of salinity can be made from the logs. Rw / ~ Rwa - ~ a The RWA curve produced from this calculation gives a range of values between 0.275 and .86 ohms at 75° F and is shown in an expanded scale in Figure-2, Track- 6. A Pickett plot of the RWA data is displayed in Figure 3 showing a minimum RW of about .275 @ 75° F. The plot is subdivided into low, medium, and high RW zones by color. A color histogram showing the RWA values in the clean sands is given in Figure-4. Using the same color scheme the location of the RW values in the sands is given in the Figure-5 log plot. Most of the RWA curve calculates in the low to medium range. The average RW value from the histogram analysis is .43 @ 75° F which is equivalent to about 11,500 ppm chlorides. The lower RW picked from the Pickett plot is .275 75° F which is equivalent to about 22,000 ppm chlorides. • • Figure 2 SP is erratic probably due to electrical noise and does not correlate well with the GR.

Design Discussion Drilling Program Jacob's Ladder is planned to a total depth of 12,500'. It will test a collapsed cave fades in the carbonate Pennsylvanian Wahoo Formation of the Lisburne group. The casing program will allow for an additional string of casing to be set and still have a 6" hole on bottom. The trouble free plan presented in this procedure calls for a TD hole size of 8 1/2". The well schematic is shown in Figure 1. The proposed drilling time versus depth is shown in Figure 2. Conductor Casing 20" conductor will be pre-set at 80' by auger drilling and batch cementing. Surface Casing (13 3/8")16" Hole Section 80' - 3,500' The goal is to cover up the unstable gravel and conglomerates with surface pipe. These appear to be sensitive to both time and circulating temperature. The base of the permafrost is expected at 1,601' NID. There will be gravel high in the section with sand and shale sequences following. There is potential for gas hydrates to exist although none have been reported in the offset wells. Frequent, high viscosity sweeps will be required for hole cleaning. The shoe depth targets the siltstones and shales immediately below this conglomerate section to obtain a minimum FIT of 12.5 ppg. Intermediate Casing (9 5/8") 12 1/4" Hole Section 3500' -11,000' The goal of this section is to drill to the top of the Lisburne Dolomite, through the Kavik shale. The intermediate casing will protect and stabilize the intermediate hole, allowing continued drilling to the target in the next hole section. This well targets a large collapse feature that starts at the HRZ marker and goes down through the Lisburne Dolomite. The shoe depth targets the base of the Kavik Shale, just above the Lisburne Wahoo to obtain a FIT of 15.4 ppg or better. It critically important set pipe above the Lisburne (without penetrating it) and also to cover most of the Kavik shale. Production Liner (7") 8 I/Z" hole Section 11,000' -12,500' The Lisburne is expected to be a collapse cave system similar to the karst plays as seen in the Ellenberger in the Permian basin. The potential exist for fractures, bit drops and severe lost circulation. The Lisburne is expected to be normally pressured, hydrocarbon bearing dolomite. A liner was selected rather than a full string of 7" casing. Successfully cementing a full casing string will be difficult and remedial cementing will require perforating. A liner with a liner hanger/packer can isolate the top of the liner even with lost circulation. A 7" tie back string can be run for completion purposes depending on well results.

These will become unstable with exposur time d high circulating temperature. The base of the permafrost is expected to be at 1,601'MD. will be gravel high in the section with mud, sand, and shale sequences following. The potential for gas hydrates exists although none have been reported in the offset wells. Frequent, high viscosity sweeps will be required for hole cleaning. The shoe depth targets the siltstones and shales immediately below this conglomerate section to obtain a minimum FIT of 12.5 ~ pPg• The Kad River -1 encountered 1,300' of gravel and required 300 vis to clean up. Flowline temperature was 54-58 Deg's F and may have contributed to the hole sloughing. Surface pipe was set at 2,188' Additional gravel was found after drill out and gumbo gave trouble with bit balling. Consider using detergent in this section. The Lake 79 Federal 1 encountered gravel and conglomerate to 3,700' on the mud log. Reported abundant sloughing and stuck DP on connections around 800'. Found bridges on bit trip from 1,170' to 1,422'. No cement returns to surface. Offset wells have not reported any lost circulation or abnormal pressure in this section. The major risk in this section is hole cleaning. High viscosity, frequent sweeps, controlled drilling and low circulating temperatures will mitigate risks. 1.2 Casing Point Selection The 13 3/8" surface string will be set and cemented at approximately 3,500'. This depth is chosen to isolate the unconsolidated surface gravel and conglomerates and provides sufficient shoe strength to drill the next hole section. 1.3 Well Control This hole section will be drilled with a 21 1/4" diverter.

Mud should cover 2/3 of the shaker screen during drilling operation and not require constant washing to prevent blinding. Cuttiugs Collection: Treated or non-treated cuttings will be trucked and disposed of at an approved disposal site. 1.5 Detailed Drilling Procedures Preparation• The following components and drilling parameters are for guidelines only: Make/Type Jets WOB RPM Pump Press Flow 1/32' MT S GP Mill tooth 3x18 0-5 60-100 800 700-900 12CJ Spud BHA: 16"Bit, Bit sub, 1 x 8" DC, String Stabilizer, 5 x 8" DC, X/O, Jar, X/O, 21 x 5" HWDP. This is to allow for maximum bit weight upon starting well. Note: All Near Bit Subs to be bored & fitted with Baker Model G, or equivalent float. Install Totco ring above float. As part of the location construction, a 20" conductor pipe will be groove cut and will have been cemented approximately 80' depth. Drilling 16" hole: 1. Install a 20" FMC SOW Landing ring on the 20" casing with adapter flange for the 21 1/4" diverter. Ensure proper spacing to accommodate remaining wellhead sections. 2. Test the kelly hose and associated line to the mud pumps to 3,000 psi prior to spudding. Check that Pop Off's on pumps are in place and set below the liner's burst rating. 3. Drill 20 ft of new formation and perform FIT. Record for AOGCC report. Drill to (3,500 ft casing point and accommodate the length of the casing to land 13 3/8" mandrel into the load ring in the 20" casing. The full casing weight should rest in the landing ring. Circulation rates of 700 gpm to 900 Confidential Page 16 of 48 10 August 2006 Jacob's Ladder Drilling Program gpm should achieve good hole cleaning with frequent 300 vis sweeps. Penetration rates may have to be controlled to maintain adequate hole cleaning and not to overload surface equipment. Formation integrity test: The test should be conducted by pumping at a constant rate of 1/a or 1/2 bbl/min. Record and graph the pressures and cumulative volumes every .25 to 0.5 bbl. Test to an EMW of 12.5 ppg after 20 foot drill out beneath 20" conductor. If FIT result is < 12.5 ppg EMW, consult with the Drilling Manager. 4. At TD, circulate and condition the hole. Make a short wiper trip to check for drag and fill. Avoid circulating without reciprocating the drill pipe. Drop Totco inclination survey if hole conditions allow and POOH. Note: the AOGCC requires surveys every 500'. There's no reported deviation problems in the ~ surface hole in any offsets. 1.6 Casing Operations Information• The following casing will be used: 13 3/8" casing Connection Burst Psi Collapse Psi Tension 1,000lbs. 681b/ L-8 BTC 5,020 2,260 1,545 ~~-- BTC casing torque should be checked by the position of the •, which should be within 1 %2 threads of the box. A very approximate "rule of thumb" for the torque is 800ft/ lbs per inch. But it is the position of the triangle stamped on the pin connection that is critical. Note: Identify the 13 3/8" casing joint that will land out at the level of the "A" section wellhead installation. Verify that the proper torque was used on the casing mandrel and landing joint. Ensure 13 3/8" x 2" 1502 Weco circulating swedge is on the rig floor. A drawing of the casing string is presented in Appendix H1. Running 13 3/8" Casing: MU 13 3/8" float shoe, two (2) 13 3/8" jts and float collar. Run 13 3/8" casing. BakerLock float shoe, BakerLock and strap shoe jts, BakerLock float collar and first joint. Set port collar at 1,000' from surface. Run centralizers above and below float collar. Run additional centralizers every 400' to surface. Do not run a centralizer within 200' of surface since it may / prevent a top job with 1" tubing. Wash the casing down if necessary to land 13 3/8" wellhead into the load ring in the 20" casing. Confidential Page 17 of 48 10 August 2006 ~ • Jacob's Ladder Drilling Frogram 1.7 Cementing Operations Information• The casing will be cemented from the 13 3/8" shoe to surface. Cement volumes and rates are based on the information provided in the Cementing program, and finalized when actual field conditions are known. Detailed cement properties are to be provided by the cementing company upon completion of cement testing with field samples. Check to ensure the casing will not float during cementing. The weight of the casing should be sufficient to prevent floating. A considerable amount of cement, above the theoretical hole volume to obtain cement returns to surface. Plan to pump a minimum of 300% excess in the Permafrost and 50% excess to the casing shoe. Check that Cementer has 1" tubing in case surface returns are not achieved and problems arise with opening the port collar. A port collar will be set at 1,000' to assist in lifting cement from that point to the surface. The Lake Federal did not get cement returns to surface. The fracture gradient of the permafrost and gravel zones are unknown so lifting cement from the casing shoe to the surface may be difficult. Cementin~• Send in field samples of cement, chemicals and mix water for the cement company to confirm the cement recipe. 2. Rig up cementing unit. Be sure that mud pumps are setup to either transfer mud to the cementing unit or to displace the cement out of the casing. 3. Install cement head. Circulate a minimum 1 1/2 times the annular volume or the casing internal capacity, whichever is the larger. Reciprocate casing if possible, maximum of 150k lbs overpull. Note: Check OD's of all plugs and ID's of cement heads to verify that plugs will pass completely through the cement head and the connection below the head or any swedge used. 4. Rig up the cementing unit and pressure test all cementing equipment to 3,000 psi. 5. Pump 10.2 ppg MudPUSH* II spacer ahead of job. 6. Drop bottom plug. Plug should be dropped in a viscous fluid only. 7. Mix and pump 10.7 ppg permafrost ARCTICSET Lite lead slurry followed by 12.5 ppg DeepCRETE tail slurry. Volumes should be designed to bring cement to surface. 8. Drop the top wiper plug followed by a minimum of 2 bbls of cement (cement in the lines and bottom of the tub). Pump 10 bbls fresh water spacer and displace mud with cement pump. Insure that plug has left the cement head. 9. Bump plug. Release pressure and check for back flow. If the floats do not hold, pump back the volume bled back, and hold pressure on the casing until the cement sets up. 10. If cement does not come to surface pick up and run in hole with the port collar combination tool and rotate (per specs) to open port collar and circulate for 2 hours. Confidential Page 18 of 48 10 August 2006 n Jacob's Ladder Drilling Program 11. Pump second stage 12.5 ppg ARCTICSET Lite permafrost cement. Drop top plug. Displace casing to port collar. Bump plug and close port collar. Release pressure and check for flowback. If flowback occurs, pump back volume bled back and hold pressure on casing till cement sets. 12. Drain and clean out 21 1/4" diverter and flowline. Clean and jet the cellar. Observe the 13 3/8" x 20" annulus to see if cement is falling. Note: Mud loggers will monitor fluid returns throughout the cementing operations and immediately report any unscheduled gain or loss of fluids. Immediately upon bumping the plug and shutting down the displacement pumps, check the 20" x 13 3/8" annulus to ensure the well is not flowing. Also, If cement returns falls back, "top" out the 13 3/8" x 20" annulus with cement to prevent freezing. 1.8 BOP & Wellhead Operations 1. Remove 13 3/8" landing Joint and nipple down the 21 1/a" diverter and landing ring adapter. 2. Install the 13 3/8" (slip 1 x 13 5/8" SM FMC casing head. =~-fin UJ~~'" 3. Test the wellhead to ,58 si based on 70% collapse of 13 3/8", 68 pp ,`HEf~ _ _, BTC casing using clear water only, hol or 10 minutes. Record for AOGCC report. 4.

NU BOP stack consisting of: 13 5/8" annular preventer, 13 5/8" M double ram preventer with blinds in the top position and 5" Rams in the lower position, 13 5/8" lOM drilling spool with 2 x 4 1/16" lOM outlets, 13 5/8" single ram preventer fitted with 5" rams. Test the BOP system as described in the well control section. S ~ ~ u 5. Close the blind rams and pressure test the 13 3/8" casing ~;$6II si for 10 min. Record for AOGCC report. If cement in 13 3/8" annulus has fallen out of 'en pump cement into 13 3/8" x 20" annulus to bring cement level up to base plate of "A" section wellhead. Confidential Page 19 of 48 10 August 2006 Jacob's Ladder Drilling Program 2.0 12 1/4" Hole and 9 5/8" Casing 2.1 Offset Data & Precautions No significant hole stability issues reported in the offset wells. The Lake 79 federal reported an inclination survey of 4 %2 deg's at 9,132' and the rest were 1 or less. The Alpenglow had one survey over 1 degree, 1.08 deg's @ 8588'. The Toolik Federal 1 reported inclination of 1 degree or less except from 9,607 to 10,675'. The surveys were 4 I/2 @ 9,607', 8 %2 @ 9,870' 7 3/4 @ 10, 252', 6 1/2 @ 10,335', 5 3/4 @ 10,492' and 3 1/z @ 10,675'. No abnormal pressure or lost circulation is expected in this interval. However watch for excessive sloughing shales, background gas and tight connections which may be indicating abnormal pressure. The offset wells TD'd with 10.5 ppg and 10.0 ppg mud weights without any drilling events indicating abnormal pressure or any reported lost circulation. The major risk is in this section are; 1) hole deviation in the collapse zone, below the HRZ marker 2) selecting a adequate casing point without drilling into the Lisburne. The collapsed zone may not have correlative markers with the offset wells so selecting a proper casing point may be difficult. 2.2 Casing Point Selection The goal of this section is to drill to the top of the Lisburne Dolomite, through the Kavik shale and set casing to isolate the intermediate hole. It's critically important not to drill into the Lisburne Dolomite in the 12 '/4" hole since there could be severe lost circulation in the Lisburne. This well targets a large collapse feature in the Lisburne which may affect the depths of some of the shallower intervals. The shoe depth targets the base of the Dark Gray shale, just above the Lisburne Wahoo to obtain a FIT of 15.4 ppg or better. 2.3 Well Control The following well control equipment will be utilized for drilling this section: 13 5/8" lOM BOP stack consisting o£ 13 5/8" SM annular preventer, 13 5/8" lOM double ram preventer with 5" pipe rams in the top position and blind rams in the lower position, 13 5/8" lOM drilling spool with 2 x 4 1/16" lOM outlets c/w 2 - 4 1/16" lOM choke valves and 2 - 2 1/16" lOM kill valves, and a 13 5/8" lOM single ram preventer fitted with 5" rams. The BOP, choke and kill lines, choke manifold, stand pipe, inside BOP, Kelly hose and safety valve should be tested after original installation along with a full accumulator test. Test frequency is required every 7 days during normal drilling operations and additionally, after any repair work. Record for AOGCC report. E ui ment Test reesure and duration Annular preventer 250 psi / 2,500 psi for 10 minutes ea. Pipe rams, blind rams, choke & kill valves 250 psi / 5,000 psi for 10 minutes ea. Safety valves and standpipe 250 psi / 5,000 psi for 10 minutes ea. Confidential Page 20 of 48 10 August 2006 Jacob's Ladder Drilling Program Run "Pit drills" every Tour until the crew's efficiency is satisfactory and weekly afterwards. Update the kill sheet every tour. Check slow pump rate pressure and record on Tour Sheet.

PU and space out to land mandrel hanger in wellhead with full casing weight. 2.7 Cementing Operations Information• The casing will be cemented from the 9 5/8" shoe to 500' above the Schrader Bluff. Cement volumes and rates are based on the information provided in the Cementing program, and finalized when actual field conditions are known. Detailed cement properties are to be provided by the cementing company upon completion of cement testing with field samples. Cementing 9 5/8" Casing: 1. Send in field samples of cement, chemicals and mix water for the cement company to confirm the cement recipe. 2. Rig Up cementing unit. Be sure that mud pumps are setup to either transfer mud to the cementing unit or to displace the cement out of the casing. 3. Install a cement head. Circulate a minimum 1 1/2 times the annular volume or the casing internal capacity, whichever is the larger. Reciprocate casing if possible. Note: Check OD's of all plugs and ID's of cement heads to verify that plugs will pass completely through the cement head and the connection below the head or any swedges used. 4. Rig up the cementing unit and pressure test all cementing equipment to 3,000 psi. 5. Pump 12.0 ppg MudPUSH* II weighted spacer ahead of job. Confidential Page 23 of 48 10 August 2006 Jacob's Ladder Drilling Program 6. Drop bottom plug. Plug should be dropped in a viscous fluid only. 7. Mix and pump a 15.8 ppg Class G slurry per cementing program. j 8. Drop the top wiper plug .Pump 12 bbls weighted spacer and displace mud with cement pump. Insure that plug has left the cement head. 9. Bump the plug with 500 psi over the final displacement pressure and hold this pressure momentarily to check for major leaks. If the plug does not bump, do not pump more than half of the shoe track volume. 10. Release pressure and check for back flow. If the floats do not hold, pump back the volume bled back, and hold pressure on the casing until the cement sets up. Note: Mud loggers will monitor fluid returns throughout the cementing operations and immediately report any unscheduled gain or loss of fluids. Immediately upon bumping the plug and shutting down the displacement pumps, check the 9 5/8" x 13 3/8" annulus to ensure the well is not flowing. 11. Drain and clean out BOPE and flowline.

Confidential Page 24 of 48 10 August 2006 Jacob's Ladder 3.0 8 1/2" Hole and 7" Liner 3.1 Offset Data and Precautions Drilling Program The Lisburne is expected to be a collapse cave system similar to the Ellenberger in the Permian basin. The potential exist for bit drops, severe lost circulation, fractures. The Lisburne is expected to be normally pressured, hydrocarbon bearing dolomite. The major risk in this section is severe lost circulation causing hole collapse in the shales between the casing shoe and the top of the Lisburne Dolomite. Consider maintaining a LCM pill in the pits for immediate use. Target 10.5 ppg mud for this section and plan ahead to minimize cement contamination of the mud while drilling out. If the hole collapses, one option is to set a CIPB and whipstock out of the 9 5/8" in a shale section (*below 9,000') that will provide a sufficient shoe and drill to TD with etting the 7" until TD is reached. If this option can not be accomplished consider setting a . IBP./and whipstock out the 9 5/8". Seta 7" liner above the Lisburne and drillout with 6 1/8" hol~:-2~~4 1/z" liner can then be set inside the 7" liner. Abnormal pressure is a risk but not expected in the Lisburne. 3.2 Casing Point Selection The casing point is set at +/- 12,500 ft of the base of the Lisburne Dolomite. This will test the entire collapse feature seen on seismic. 3.3 Well Control The following BOP configguration should be used: 5 Ihl ~ ~ Annular: 13 518" ~~ psi annular BOP Double: 13 5/8" l OM psi double ram BOP dressed w/ 5" rams on top & blind rams on bottom Mud Cross: 13 5/8" lOM psi with two 4 1/6" lOM psi outlets Single: 13 5/8" l OM psi ram BOP dressed w/ 5" pipe rams. The BOP, choke and kill lines, choke manifold, stand pipe, inside BOP, Kelly hose and safety valve should be tested after original installation along with a full accumulator test. Test frequency is required by AOGCC every 7 days during normal drilling operations and additionally, after any repair work. To save time, the choke & kill lines and choke manifold may be tested while picking up BHA and running in hole prior to drill out. Record for AOGCC report.

Perform a FIT as described below. Confidential Page 26 of 48 10 August 2006 • • Jacob's Ladder Drilling Program Formation integrity test: The test should be conducted by pumping at a constant rate of 1/4 or 1/2 bbl/min. Record and graph the pressures and cumulative volumes every .25 to 0.5 bbl. Test to an EMW of 15.4 ppg at 9 5/8" shoe. If FIT result is < 15.4 ppg EMW, consult with the Drilling / Manager. Record for AOGCC report. 5. Run Vertical Seismic Profile with wellsite geologist. 6. While drilling below the 9 5/8" shoe, limit the rotary speed to 80 RPM until the last stabilizer is out of the casing. 7. Conduct a "Pit drill" before drilling into the Lisburne Dolomite. Be sure pit totalizer alarms are working properly. Ensure adequate barite is on location to increase the mud weight by 2.0 ppg. ~ Flow-check connections while drilling the first 200 ft of the Lisburne. Be prepared to fill casing with water in the event that total circulation is lost and the fluid level drops in the casing. PU and flow check if the bit stalls or drops or if torque becomes erratic. 8. Drill ahead as required to the Lisburne core point as directed by wellsite geologist. Circulate up samples at the geologist's discretion. Keep all drilling parameters (RPM, GPM & WOB) constant 30-60 ft above desired core points to aid the Geologist in correlation and core point selections. 9. POOH to core. The first core barrel run in this well will not exceed 30' in length. If the first core run is trouble free then consideration may be given to increasing the core barrel length to a maximum of 90 ft on subsequent runs. 10. At casing point, sweep the hole with ahigh-vis pill, circulate bottoms up, and check that the shakers are clean. Make a wiper trip to the 9 5/8" shoe, check for flow. Back-ream with top drive if necessary. 11. Circulate past bottoms up or until the shakers are clean. 12. Make a flow check, and POOH. 13. Make a flow check at the shoe and before the BHA is in the BOP. 14. Rig up Schlumberger wireline and run every log in the price book. Note: It is the Drilling Supervisors responsibility to supervise logging operations. 15. Monitor hole conditions during logging operations. Review caliper logs to determine if any tight spots exist in the wellbore that might hamper casing operations. 16. TIH for wiper trip. Circulate and condition mud. POOH laying down 5" drill pipe. ~' 17. Pull the wear bushing. Confidential Page 27 of 48 10 August 2006 Jacob's Ladder Drilling Program 3.6 Liner Operations Information• A liner option was selected for the following reasons 1. If severe lost circulation exist, isolating the 8 lh" hole will be much easier with a liner rather than a full string of casing. If the liner top does not test, it can be squeezed. 2. Setting plugs for the Temporary Abandonment can be done with the 5" Drill Pipe. 3. Normal pore pressure is expected in the Lisburne therefore the liner is proposed. The following casing will be used: 7" casing Connection Burst, psi Collapse, psi Tension 10001bs 29 ppf L-80 BTC 8,160 7,020 746 Lay out and inspect the 7" casing while drilling the 8 1/2" section. A drawing of the liner is presented in Appendix H3. Running 7" Liner: 1. RU fill-up tool and casing running tools. 2. Run 7" shoe track. Thread lock all connections on the 1St_3ra jts in the hole. Function test the float collar & float shoe after they are run. Run centralizers above and below float collar and every 400' afterwards in open hole and every 100' in cased hole. Fill the casing every joint. Mud loggers to monitor the fill up and immediately report any losses or gains versus theoretical. Install centralizers per program. 3. PU Baker ZXP-HMC Liner/Packer hanger and x-over. Minimize surge pressures by avoiding rapid acceleration and controlling running speeds of the liner string. Monitor losses and change the running speed if necessary. Break circulation at the 9 5/8" casing shoe to break gel strengths before entering open hole. 4. Continue to run the 7" liner. 5. Break circulation and wash the last joint of casing down. Tag bottom. 6. Drop setting ball, pressure up and set packer. Continue pressuring up to blow setting ball clear. PU and rotate string to 10 rounds to the right to release from hanger. Verify setting tool is free. Do Not expose "dogs" that set the packer. 3.7 Cementing Operations Information: Send in field samples of cement, chemicals and mix water for the Cement Company to confirm the cement recipe. Cement volumes and rates are based on the information provided in the Cementing Program, the caliper, and when actual field conditions are known. Detailed cement properties will be provided by the cementing Service Company upon completion of cement testing with field samples at the anticipated wellbore conditions. Confidential Page 28 of 48 10 August 2006 Jacob's Ladder Drilling Program Cement slurry weight will be determined by ultimate mud weight required to drill the section. The cement slurry density will be at least 0.5 ppg greater than the final mud weight. Planned TOC will be 180-200 inside the 9 5/8" casing. Adjust volumes accordingly. Cement job will be displaced with the cementing unit. If plug does not bump, do not displace more that %2 the shoe track theoretical volume. Cementing 7" liner: Send in field samples of cement, chemicals and mix water for the cement company to confirm the cement recipe. 2. Install cementing head if not already installed. Note: Check OD's of all plugs and ID's of cement heads to verify that plugs will pass completely through the cement head and the connection below the head or any swedges used. 3. Pressure test all pumping equipment and lines to 5,000 psi for 10 minutes. 4. Pump a 12.0 ppg MudPUSH* II weighted mud push spacer. Drop bottom plug. Mix and pump slurry while monitoring the pressure, volumes and losses throughout the job. 5. Drop top plug and insure plug leaves the cementing head. Pump the required displacement volume w/ the cementing unit. Bump the plug to 500 psi over the final displacement pressure. Hold pressure for 5 min. Note: Mud loggers will vigilantly monitor fluid returns throughout the cementing operations and immediately report any unscheduled gain or loss of fluids. Immediately upon bumping the plug and shutting down the displacement pumps, check for flow. 6. Release pressure and open the displacement line to verify that the floats are holding. If the floats do not hold and the well flows back, PU, expose setting "dogs" and set Top Packer. POOH 10 stands and reverse circulate 1 casing volume. 7. Open casing head valve and monitor for flow.

The Pore Pressure Chart (Appendix B) shows the mud weights employed on these wells along with the anticipated pore pressure on the Jacob's Ladder well. The Lake Federal well reached TD (15,544') with a 9.9 to 10 ppg mud weight with the highest mud weight of 10.2 ppg between 10,000' and 11,000'. The well did not encountered any sloughing shales, excessive fill on trips, excessive tight hole or high background gas that is typically associated with abnormally pressured intervals. The Kad River 1 reached TD (13,161') with a ppg mud weight and also did not encounter any drilling events typical of an abnormally pressured interval. In addition, a DST tested salt water at 10,621'. Although a definitive FSIP was not reached, the mud weight (10.7 ppg) controlled (and therefore exceeded) the pore pressure in that permeable zone. This indicates that the interval does not contain abnormal pressures. A DST was also run on another offset well, the Kadler State 15-9-16 at 9,767'. It recovered saltwater. Again, there was not a definitive FSIP but the 10.5 ppg mud weight controlled (and therefore exceeded) the pore pressure in that permeable zone. This indicates that the interval does not contain abnormal pressures. The DST's, mud weights and drilling conditions are consistent with a normally pressured environment in these offset wells. Log analysis of these offset wells indicates potential for abnormally pressured intervals below 8,500'. However, we believe that the results are driven by lithology changes rather than abnormal pressure. A normally pressured environment is expected in the Jacob Ladder 1 well, typical of this area. Confidential Page 32 of 48 10 August 2006 Jacob's Ladder Fracture Gradient Discussion Drilling Program The closest reported leak off test was in the Alpenglow well drilled in 1992 by Unocal. A leakoff test of 15.4 ppg was achieved at 2,820' below the 13 3/8" casing shoe. This corresponds to the calculated fracture gradient of 0.80 psi/ft from the sonic logs on this well (Appendix C). The HASP used a 15.4 ppg for the 13 3/8" casing shoe and 9 5/8" casing shoe in the Jacob Ladder 1 well. Procedure for Calculating Maximum Anticipated Surface Pressure (HASP) 1. Drilling Below Conductor Casing HASP while drilling below the 20" conductor shoe will be the lesser of the formation pore pressure (less a full gas column to the surface) at the next (13 3/8") casing shoe or the formation fracture pressure at the last (20") conductor shoe, less a full gas column to the surface. Based on offset well data, the highest formation pressure expected in the 16" hole section is 1,638 psi at the 13 3/8" casing setting depth of 3,500' TVD (or 0.468 lfs~/ft) and the formation fracture pressure at the 20" shoe depth of 80' TVD, minimum 12.5 ppg EMW (0.65 psi/ft). Complete evacuation of the wellbore, except fora 0.1 psi/ft gas gradient, is assumed. HASP Calculation for Drilling 16" hole section HASP (pore pressure) _ (3,500 ft)(0.468 - 0.1) = 1,288 psi j HASP (Fm Breakdown) _ (80 ft)(0.65 - 0.1) = 44 psi Thus, HASP in the 16" hole section is 44 psi, below the diverter's 2,000 psi rated working pressure. 2. Drilling Below Surface Casing HASP while drilling below the 13 3/8" casing shoe will be the lesser of the formation pore pressure (less a full gas column to the surface) at the next (9 5/8") casing shoe or the formation fracture pressure at the last (13 3/8") casing shoe, less a full gas column to the surface. Based on offset well data, the highest formation pressure expected in the~2 1/4" hole section is 5,434 psi at the 9 5/8" casing setting depth of 11,000' TVD (or 0.494 ps~/ft) and the formation fracture pressure at the 13 3/8" shoe depth of 3,500' TVD, minimum 15.4 ppg EMW (0.8 psi/ft). Complete evacuation of the wellbore, except fora 0.1 psi/ft gas gradient, is assumed. HASP Calculations for Drilling 12-1/4" hole section HASP (pore pressure) _ (11,000 ft)(0.494 - 0.1) = 4,334 psi HASP (fm breakdown) _ (3,500 ft)(0.8 - 0.1) = 2,450 psi Therefore, HASP in the 12-1/4" hole section is 2,450 psi. It is planned to routinely test the BOPE to 5,000 psi. 3. Drilling Below Intermediate Casing HASP while drilling below the 9 5/8" casing shoe will be the lesser of the formation pore pressure (less a full gas column to the surface) at TD or the formation fracture pressure at the last (9 5/8") Confidential Page 33 of 48 10 August 2006 r r Jacob's Ladder Drilling Program casing shoe, less a full gas column to the surface. Based on offset well data, the highest formation pressure expected in the 8 1/2" hole section is 6,175 psi at the TD of 12,500' TVD (or 0.494 psi/ft). The formation fracture pressure at the 9 5/8" shoe depth at 11,000' TVD is 15.4 ppg EMW (0.801 psi/ft). Complete evacuation of the wellbore, except fora 0.1 psi/ft gas gradient, is assumed. MASP Calculations for Drilling 8-1/2" hole section MASP (pore pressure) _ (12,500 ft)(0.494 - 0.1) = 4,925 psi ~ MASP (fin breakdown) _ (11,000 ft)(0.801 - 0.1) = 7,711 psi Therefore, MASP in the 8 1/2" hole section is 4,925 psi.

Hydrogen flame ionization (FID) Total Gas and (FID) Gas Chramatograph detectors were employed to detect and analyze formation gases. Constant mud gas was generated by Texaco's patented Quantitative Gas Measurement (QGM~") electrically driven gas trap located at the shale shaker header box and extracted continuously from the trap to the unit by sample pumps. The gas trap was frequently cleaned and positioned to obtain optimum sampling, and the gas system wars tested and calibrated on a regular basis. Cuttings samples were collected at regular 30' intervals as directed by Anadarko's sampling program. Sample interval was decreased to 10' in shows and in the Lisburne formation. Gas samples were collected as directed by Anadarko's sampling program. 500' intervals through the surface hole and 100' intervals #hrough intermediate section. • [~ EPOCH ~'~ Jacob's Ladder "C" • DAILY ACTIVITY SUMMARY Note: Rig activities are for the 24 hours ending at 05:00 AM on the date indicated. 2/18/47 Circulate pumps, tighten hammer union on stand pipe, pressure up and bleed off.
