Box 1367 Anchor Point, AK 99556 RE: Well Site Clearance – Griner No. 1 (Permit to Drill 202-041) and Endeavour No. 1 (Permit to Drill 205-213) Dear Mr. Overson: The Alaska Oil and Gas Conservation Commission (AOGCC) is the state agency that regulates oil and gas well drilling in the state. Part of our duties are to make sure that wells are drilled safely and when there’s no more utility for the well that they are properly plugged and abandoned and that the drill site is properly restored. In March and April 2002, Union Oil Company of California (Unocal) drilled the Griner No. 1 exploratory well on land which Kenai Peninsula Borough records indicate you currently own along the Sterling Highway and Docs Rd (Kenai Peninsula Borough Parcel ID No. 16919033). Unocal plugged and abandoned the well in accordance with AOGCC regulations, and the plugging operations were verified by an AOGCC field inspector on April 21, 2003. In April and May 2006, Aurora Gas, LLC (Aurora) drilled the Endeavour No. 1 exploratory well on that same property. Aurora plugged and abandoned the well in accordance with AOGCC regulations, and the plugging operations were verified by an AOGCC field inspector on May 12, 2006. Although the wells are mechanically properly plugged and abandoned, AOGCC regulations also require operators to conduct site clearance work and successfully pass AOGCC site clearance inspections. Specifically, 20 AAC 25.170(a) states: At or after the time that a well drilled onshore is abandoned and before the earlier of one year after the well abandonment or the expiration of the owner’s1 rights to the property, (1) The operator shall remove the wellhead equipment and casing to a depth at least three feet below original ground level and install a well abandonment marker in accordance with 20 AAC 25.120; and 1 In this instance “owner” refers to the operators (Unocal and Aurora), not to the landowner. Page 2 of 2 (2) Unless the operator demonstrates to the commission that the surface owner has authorized a different disposition to facilitate a genuine beneficial use, the operator shall A. Remove all materials, supplies, structures, and installations from the location; B. Remove all loose debris from the location; C. Fill and grade all pits or close them in another manner approved by the commission as adequate to protect public health and safety; and D. Leave the location in a clean and graded condition. Unocal and Aurora completed the activities required under part (1) of this regulation by removing the wellhead, cutting the casing off below ground, and installing a marker plate, but Unocal and Aurora never arranged for the AOGCC to conduct site clearance inspections. AOGCC does not know if Unocal or Aurora complied with requirements (2)(A) to (2)(D), above, or if Unocal and Aurora otherwise left the well locations in a condition that is acceptable to you. If the sites were not cleared in compliance with 2(A)-(2)(D), the AOGCC may potentially have means at our disposal to remedy the situation. Please send a letter or an email to the AOGCC (at the letterhead address or to AOGCC.Reporting@alaska.gov) advising as to whether or not Unocal and Aurora left your property in a manner that is acceptable to you after plugging and abandoning the Griner No. 1 and Endeavour No. 1 wells. If you have any questions, please feel free to contact Dave Roby of our staff at 907-793-1232 or dave.roby@alaska.gov. Sincerely, Jessie L. Chmielowski Commissioner Jessie L.

Box 101 Anchor Point, AK 99556-0101 Re: Griner #1 PTD 202-041 Plug and Abandon Dear Mr. And Mrs. Griner: On April 21, 2003, AOGCC Inspector Lou Grimaldi inspected the near surface work performed by Unocal to plug and abando]J (P&A) this exploration well. Unocal had previously sought and was given Commission approval to P&A the well according to the Commission regulations. Based on the information sub- mitted by Unocal and Inspector Grimaldi's surface inspection, Unocal has suc- cessfully performed the planned work. At the time of the inspection, the only remaining work was to remove the culvert "cellar" and the "mouse hole" (12" pipe set in the earth used to hold the next joint of drill pipe). When the culvert and mouse hole are removed, Unocal will fill in all excavations leaving the ground surface at local grade. The Commission may make another site inspec- tion, although at this time Unocal is expected to submit photos to document the additional work done. Since the well is located in an active gravel pit, it is recommended that the well position be conspicuously noted in the pit records. If there is gravel removed from the immediate area of the well, the abandoned well structure could be ex- posed creating a collision hazard for personnel and equipment. At the present time, the top of the well casings is about 5' below local grade. If pit operations are planned in the immediate area of well, you should contact Unocal so that arrangements can be made to "cut off' the well casings at greater depth. If you have any questions with regard to the abandoned well, please contact the Commission at 907-279-1433. ~~...ujn Thomas E.

MEMORANDUM State of Alaska Alaska Oil and Gas Conservation Commission TO: Randy Ruedrich, f~ Commissioner DATE: April 21,2003 THRU: Maunder/Regg, í:?&~ S\b~ P. I. Supervisor's' '\ FROM: Lou Grimaldi, Petroleum Inspector SUBJECT: Surface Plug & Abandonment, Unocal Griner #1 Exploratory Monday, April 21, 2003: I verified cement to surface on all strings and the placement of the subsurface monument on the Unocal exploratory well "Griner #1". I met Donnie Fowler (Unocal rep.) on location and was shown the casing stub. The casing had been cut off 64" below grade and showed good cement in all strings to surface. A 1" thick plate had been cut to fit the 13 3/8 conductor and had the following information bead-welded to one side; UNOCAL GRINER #1 PTD 202-041 API 50 231-20011-00 The plate was welded to the conductor in my presence. The culvert used for the cellar and the 12" mouse hole still needs to be removed before the cellar can be filled in. Doug Nienhaus (Unocal rep.) will take pictures and forward these when this has been completed. This location sits in the middle of an active gravel pit and precautions should be taken as to not excavate too closely to this abandoned stub. I recommend this report be forwarded to the DNR informing them of the well stubs location and requesting that they place provisional requirements on this gravel pit to protect this stub from possible damage. I recommended to Doug and Donnie that some dunnage be placed over the top of the stub to help prevent damage to the stub. SUMMARY: I verified proper surface abandonment of UNOCAL's Exploratory well Griner #1.

I would like to respectfully request the following change to the abandonment as proposed and approved. As it is now proposed and approved to abandon the open perforations at 2750' - 2766': 1. Set an isolation bridge plug at 2730' 2. Dump bail 35' of cement onto the top of the plug. What I would like to propose to abandon the open perforations at 2750' - 2766': 1. Establish an injection rate into the perforations and bullhead a 835' cement plug (7.25 bbls) from the bottom of the perforations at 2766' to 1931'. Everything else in the program would remain the same as previously proposed. The reason for my wanting to do this is that it streamlines the onsite operations along with laying a much larger cement plug above the open perforations. «Griner Alternative Abandonment Schematic.doc» Regards, Larry W.

This was drilled as a monobore and complete isolation of the 7" x 3-1/2" annulus was not achieved with cement. A subsequent squeeze of the annulus/shoe did not achieve the desired isolation. Unocal is proposing to P&A the well. In discussions with the engineer, he indicated that they have some pressure on both the IA and GA. I have described the pressures in the document. Unocal proposes to shoot and squeeze each shoe. What I propose is that after performing each squeeze, that some monitoring time be allowed to confirm that the isolation they desire has been achieved. I suggest this well be a discussion topic at the Tuesday adjudication meeting. I have placed the sundry in the "hold" box in the confidential room with the N* documents. Tom ! .

This well was drilled as a monobore, with the final 3-1/2" tubular being both tubing and casing. This note is prepared to document the P&A of the well. When the well was drilled, the 3-1/2" string was cemented with sufficient cement to raise the TOC above the 7" surface casing shoe. After allowing the cement to set, a pressure test was attempted on the 3-1/2" x 7" annulus that was not successful. Unocal attempted to down-squeeze the annulus which was not successful. Subsequent testing of prospective intervals was not successful and Unocal proposes to plug and abandon the well. Within the 3-1/2" "tubing", Unocal proposes to isolate their perforated intervals using electric line set bridge plugs and dump bailed cement. This method meets the requirement of 20 AAC 25.112 (c) (1) (E). At the 7" (1721" md) and 9-5/8" (430' md) casing shoes, Unocal proposes to perforate and squeeze these intervals to improve the isolation of earlier cementing operations. Unocal has proposed these operations to provide additional isolation to what they term small volumes of coal gas that have resulted in surface pressures of 250 psi on the 3-1/2" x 7" annulus and 160 psi on the 9-5/8" x 7" annulus. According to Unocal, there is little volume associated with either pressure and the pressures bleed off quickly. I recommend that approval should be given for Unocal to perform their abandonment operations as proposed, however after perfoming each shoe squeeze sufficient time should be allowed for the cement to set and the respective annulus should be monitored to confirm that the desired isolation has been achieved. A cover letter should be prepared noting the observation requirements. Tom Maunder, PE Sr. Petroleum Engineer ) ) Unocal Corporation P.O.

Drilled and tested in the first half of the year, the well has proven non productive. The existing perforations will be plugged with a bridge plug and 35' of cement dump bailed on top. Squeeze holes will then be shot across the 7" casing shoe and the perforations squeezed with approximately 10 bbls of cement. A plug will be set at 450' and squeeze perfs shot across the 9-5/8" shoe at 420'. Approximately 4 bbls will then be pumped down the production tubing/casing and squeezed into the perforations. Once in place this plug will extend to surface. The well head will be cut off below grade and the abandonment cap installed on the casing stub.£ The location will then be released to the property owner.

The 3 1/2 by 7" tubing to casing annulus (which had been squeezed the previous evening) was pressured up to 1100 psi using base oil (#4 diesel) to 1100 psi. The pressure fell off rapidly losing 325 psi in 15 minutes (30% loss). The casing and pump lines were bled to eliminate air and a second test was performed. The annulus was pressured up to 1250 psi and lost 425 psi in 15 minutes (34% loss). The declines were almost identical indicating a channel in the cement. I discussed the tests with Harold Fahlander (UNOCAL rep.), the plan was made to push the base oil down with Nitrogen and attempt another squeeze this evening and retest again. I left location at this time.

We pumped a 12.0 ppg litecrete slurry with full returns thru the job. We pumped 25 bbls of chemical wash followed by 30 bbls of spacer ahead of the cement. We recovered all of the chemical wash and approximately 25 bbls of the spacer at surface. No cement to surface was reported which tells me channeling was not an issue. The estimated top of cement would be approx. 200' below surface. The final lift pressure recorded just before bumping the cement plug at slow pump rates was 1735 psi. The theoretical pressure differential between cement and displacement fluid is estimated at 1637 psi [(0.052) (12.0 ppg - 7.3 ppg*) (6,700' tvd)] which when compared to the final displacement pressure verifies the top of cement was very close to the surface. *Note: the displacement fluid (base oil) weighs 7.3 ppg With reference to the upcoming Griner No.1 testing operations, I am planning to test the 7" Casing X 3-1/2" Tubing annulus to 1,100 psi for 30 minutes. The integrity test performed on the 7" shoe during the drilling operations saw pressure bleed off from 1,050 psi to 1,000 psi in 5 minutes over a 9.2 ppg mud. Testing the annulus to 1100 psi over a heaver fluid column (cement and spacer) for 30 minutes will give us a definitive cement integrity test of the 7" X 3-1/2" tubing annulus. We are planning to start the testing operations on the Griner No.1 well this coming Sunday, April 7. Dowell Schlumberger is working on completing the cementing records and I will forward them to you as soon as they are available. Please advise if more information is required herein.

IT APPEARING THAT: ) Conservation Order :No. 467 ) ) Griner # 1 ) Exploratory Well ) ) March 22, 2002 ) ) 1. Unocal Alaska ("Unocal") by letter dated February 4, 2002, and received by the Commission on February 5, 2002, has requested an order allowing a spacing exception in accordance with 20 AAC 25.055 for the proposed Griner #1 exploratory well. The locations of prospective test intervals within this well may fall within 1500 feet of a property line. 2. The Commission published notice of opportunity for public hearing in the Anchorage Daily News on February 8, 2002, pursuant to 20 AAC 25.540. 3. No protests to the application were received. FINDINGS: 1) The surface location of the well is 2186' FSL, 1786' FWL, Section 3, T5S, RI5W, S.M. The projected bottom hole location for this vertical well is also 2186' FSL, 1786' FWL, Section 3, T5S, R15W, S.M. 2) An exception to the well spacing provisions of 20 AAC 25.055 (a)(2) is necessary for the drilling of this well. CONCLUSION: Granting a spacing exception to allow drilling of the Griner # 1 exploratory well promotes efficient exploration and development, and will not result in waste nor jeopardize correlative rights. Conservation Order No. 467 March 22, 2002 Page 2 of 2 '~ l ) NOW, THEREFORE, IT IS ORDERED: Unocal's application for exception to the well spacing provisions of 20 AAC 25.055 (a)(2) for the purpose of drilling and testing the Griner #1 well is approved. The Griner # 1 well may not be placed on regular production until the Commission takes additional action, upon petition, and after notic~ and hearing, to offset any advantage Unocal may have over other owners by reason of drilling Griner #1 to the exception location and to allow affected owners to produce their just and equitable share of hydrocarbons. DONE at Anchorage, Alaska and dated March 22,2002. AS 31.05.080 provides that within 20 days after receipt of written notice of the entry of an order, a person affected by it may file with the Commission an application for rehearing. A request for rehearing must be received by 4:30 PM on the 23rd day following the date of the order, or next working day if a holiday or weekend, to be timely filed. The Commission shall grant or refuse the application in whole or in part within 10 days. The Commission can refuse an application by not acting on it within the 10-day period. An affected person has 30 days from the date the Commission refuses the application or mails (or otherwise distributes) an order upon rehearing, both being the final order of the Commission, to appeal the decision to Superior Court. Where a request for rehearing is denied by nonaction of the Commission, the 30-day period for appeal to Superior Court runs from the date on which the request is deemed denied (i.e., 10th day after the application for rehearing was filed).

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. 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. Well must be mudlogged and sampled from 400' MD to total depth. Well Logging - Well must be logged from 40' MD to 400' MD with cased hole GR, and from 400 MD to surface casing shoe with GR/SP/Resistivity and porsity tool. Please note that disposal of fluids generated from this drilling operation down the annulus of the NNA #1 is subject to separate approval and must comply with the requirements and limitation of 20 AAC 25.080. 20 AAC 25.200(d) requires that all wells capable of unassisted flow must be equipped with tubing and a packer to isolate the production casing from the produced fluids. Your design does , not include tubing and a packer. The proposed design employs a 3-1/2" tubular string as casing and tubing. The proposed 3-1/2" string employs a seal ring in the connection to prevent gas leaks and has a burst pressure rating that provides a safety factor of 4. The likely producible fluid is methane gas, which is noncorrosive. When the string is cemented, it is planned to pump sufficient cement to place the cement top at about 1250', which is 500' above the 7" casing shoe to seal the 3-1/2" X 7 annulus~. Successfully achieving this objective is critical to well./ integrity. Please plan to submit the cementing operation records as soon as they are available. Please also note that prior to initiating testing activities a pressure test of the 3-1/2" X 7" annulus ) Pennit No: 202-041 March 6, 2002 Page 2 of2 ) will be required. Specific surface pressures will be detennined after review of the surface casing leak: off pressure and discussion with the project engineer. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

Smith Sr. Advising Geophysicist February 26, 2002 AOGCC 333 w. 7th Ave., Suite 100 Anchorage, AK 99501-3539 Attn: Steve Oavies Dear Steve: Re: Griner-1 Permit to Orill- Shallow Gas Hazards and Seismic Velocity Analysis Please find attached 7 figures I produced using seismic line NF97-7 that passes east- west through the proposed Griner-1 location. Figure 1 shows the top Tyonek structure map for the Anchor Point Prospect. Griner-1 proposed location is near the crest of the structure. Seismic line NF97-7, which is the seismic line used in the velocity study, is also shown. Figure 2 is the uninterpreted image of seismic line NF97-7 with the proposed Griner-1 location plotted. The expected Tyonek gas pay intervals lay between 0.5 and 1.5 seconds. Griner-1 will spud into the Beluga formation with the Sterling Formation being eroded by the Base Glacial unconformity. No shallow bright spots have been detected or imaged on line NF97-7 in the vicinity of the proposed location. The isovelocity plot for line NF97-7 is shown in Figure 3. The Griner-1 proposed location is shown at COP 290. The other labeled COP's are the velocity points used in the seismic processing. As you can see no major lateral RMS velocity changes are apparent in this display. Figure 4 is the depth verses RMS Velocity (or average velocity) plot for the five closest COP's to the Griner-1 location. As you can see in the plot, except for COP 230 (which suffers from edge effects), all functions track each other very closely in the shallow section from 0 to 10,000' depths. In Figure 5 the depth verses Interval velocity for the same five COP points are plotted for the total depth of the seismic section. In Figure 6 the same data is plotted again but ") ') only for the interval of ° to 12,000 feet. As you can see there appears to be quite a bit of variation in the interval velocities plotted from the section. The interpretation of this variation is complicated due to the variation in fold in the seismic section because of the numerous shallow skips at the surface due to surface obstructions (the notches can be seen in the shallow section). Severe surface static problems also degrade the data over the crest of the anticline. What can be said is that none of the interval velocity functions fall outside the envelope of all the curves plotted. At CDP 260 and 290 there is a slight decrease (50/0) in interval velocity between 2500' and 4000' but this doesn't appear to be significant since this would amount to a one velocity function shift on the velans display used in picking velocities. With the data so poorly imaged above 2500', most processors error on the high velocity side to avoid stacking in multiples. Figure 7 is a tabulation of the velocity data for the CDP's plotted in Figures 4,5, and 6. So in summary, based on the lack of any indications of shallow bright spots on the seismic line, I don't believe that there any concerns regarding shallow gas at the proposed location. Regarding seismic derived indications of over-pressuring, the data over the Anchor Point anticline is too poor to be reliable. Anchor Point Unit-1 , which was drilled one mile south of the proposed Griner-1 location, showed no signs of over- pressuring. Please look at the data and let me know if you have any questions or concerns. SinCereIY~. '~... ~ ~, LCMv) ~ Larry 1.

Commission Anchorage Reason for Addendum This Addendum is submitted at the request of the office of AOGCC to address the question of water salinity in the shallow subsurface in the Anchor Point area, specifically to determine that the surface casing proposed for the Unocal Griner #1 well is set deep enough to protect any existing potential sources of fresh water. Figures attached in support of this discussion: 1. TABLE 1 - Salinity Calculations from Well log Data, Anchor Point #1 Well 2. FIGURE 1 - Plot of Water Salinity vs Depth, Anchor Point #1 Well Discussion Formation water salinity for the interval from surface to 6800' MD was calculated using the SP and Rwa methods as recommended in "Survey of Methods to Determine Total Dissolved Solids Concentrations" prepared for EPA by Ken E. Davis Associates (1989). Data used in this evaluation included the Induction Electric log and Sonic log from the SOCAl Anchor Point #1 well in Sec. 10-T5S-R15W; this well is located approximately 6800' south of the proposed UNOCAl Griner #1 well. The Anchor Point #1 well is only well in the immediate vicinity, and is considered indicative of the shallow subsurface section to be encountered by the proposed UNOCAl Griner #1 well. Additional information on the lithology of the shallow subsurface section was provided by the Mud log from the Anchor Point #1 well. The Mud log from the Anchor Point #1 well suggests that surface gravel deposits extend to a depth of roughly 200 below ground surface in this vicinity. These surface gravels, deposited as unconsolidated glacial drift in angular unconformity atop the Beluga section below, comprise the most significant source . Page 1 ORIGINAL ') ) of fresh drinking water in the Anchor Point area. Most of the water wells in the Anchor Point area extend to a depth of less than 100' below ground level, to tap this source of fresh water. Examination of the Induction Electric log over the interval from 100' to 300' MD reveals highly resistive lithologies, while the Sonic log indicates that the rocks in this interval have on average 300/0 porosity or better. Thus, the high resistivity of this unit is suggestive of fresh formation water, rather than tight rock. The notable trend of decreasing resistivity with depth suggests that formation water gets steadily more saline from 200' to 300' MD; below 300' MD, the baseline resistivity of potentially sandy intervals is rather consistent at roughly 20 ohm-m, suggesting consistently more saline formation waters. The assumption of increasing formation water salinity with depth noted above is confirmed by the salinity calculations presented in TABLE 1. Both the SP and Rwa methods of calculating salinity give fairly consistent and presumably reliable results. An examination of the data presented in TABLE 1 reveals that formation water salinity increases from less than or equal to 1000 ppm in the shallow gravel aquifer to roughly 2500 ppm at 775' MD. At a depth of 1050' MD, formation water salinity is calculated to be 3200 ppm, or 200 ppm greater than the 3000 ppm cut-off for a source of fresh water for human consumption. Water salinity continues to increase with depth, to 4000 ppm by 2000' MD and 5000 ppm around 4000' MD. It is apparent from these calculations that the 1700' MD surface casing point proposed by Unocal in its Permit to Drill for the Griner #1 well is sufficient to protect any and all potential sources of fresh water, as required by the State of Alaska. Water salinity at the proposed casing point is likely to be in the range of 3700 - 4000 ppm, as indicated by the trend lines drawn through the data for both the Rwa and SP methods, as presented in the attached FIGURE 1.

Anchorage --''''lIBSIon Attn: Commissioner Cammy Taylor Dear Commissioner Taylor, Enclosed is an application for permit to drill for the Anchor Point Prospect, Griner Well No,1. ,;1/' This well is planned as a vertical well to a total depth of 6800', with the Tyonek Gas Sands being the only objective. We are planning to drill and cement 9-5/8" casing to a depth of +/- 400' utilizing a local water well drilling contractor prior to the drilling rig /' arriving on location. We will then nipple up BOPE and drill to 7" casing point at 1750' utilizing water base mud. Next, we will drill 6-1/8" hole to programmed well TO of 6800'/ utilizing oil base mud. Assuming the well is productive, 4-1/2" casing will be ¡.afÍ and cemented and well testing activities will commence after the drilling rig leaves location. In an attempt to drive the project economics, we have engineered several items within. (( the proposed drilling program, which deserve special mention. First, we have reviewed .1:4~.J.,¿' the relevant geology and logging information from offset wells and feel there is no.sþ r ,~ commercially viable zones above the proposed 7" casing point at 1750'. Therefore, we it~ I~ have not planned a separate logging run over this interval, but plan,Pn obtaining a camm p '/tfJ~~ hole gamma ray log at the end of the 6-1/8" open hole logging run.'" Second, we feel that /j?T~' drilling and cementing casing at 400' prior to nippling up BOPE is a much safer and V . JtÞ effective method in contrast to drilling deeper with only a diverter and shallow driven '..{. o'þ- conductor set. Examinations of locally drilled water wells, analysis of geophysical 3' information, and discussions with our water well drilling contractor all lead us to believe there will be no problems associated with running and cementing 9-5/8" casing to 400'. ,.,/ 0 R:-: , G. .'.'1 , !\i l\ 1 " : " ~,~ ~ l \.

Clean out the rathole below the shoe, and drill 20' of new hole. Circulate and condition mud. 2. Pull the drill string into the shoe. Rig up to observe annulus pressures. 3. Close the pipe rams and pump down the drillpipe at a slow rate (1/4 - 1/3 BPM) if exposed formation is permeable. A non-permeable formation should be step tested to a predetermined pressure. 4. Measure the volume pumped and plot annulus pressure-vs-cumulative volume pumped. Compare annulus pressure to drill pipe pressure and confirm both are the same. Record and plot pressure versus volume pumped. The pumps should be shut down immediately upon indication of leak-off. Record the inital, shut down pressure and the pressure after 1, 2, and 3 minutes. 5. Release pressure and record the volume of fluid recovered .in the trip tank. The point "B" shown in the attached graph at which the plot of drillpipe pressure stops increasing equally as the volume is pumped is called the P.I.T. limit, Leak Off, or pressure integrity test limit. The leak-off pressure is calculated as follows: Leak-off (EMW) = Mud weight in hole + P.I.T. (PSI) (0.052) X (shoe depth in TVD ft.) This equivalent mud weight should be made known to all drilling personnel to ensure it is not exceeded under any circumstances. See the drilling procedure for guidelines on expected LOT's or pressure integrity test limits for each casing shoe. TYPICAL PIT PLOT (psi) C "--~ SURFACE PRESS. VOLUME PUMPED (DDLS) SHUT -IN-TIME (MIN] NOTES: Point" A" will have some variance until the system begins to pressure up. Point" B" is the leak off and is abbreviated LOT. Point "C" is known as the injection pressure and is usually dependent on rate. Point "D" is known as the fracture closure pressure and may not stabilize if permeable formations are exposed. ..

Griner Well No.1 will be drilled as an offset to the Anchor Point Well No.1 which was drilled by Socal in 1962. This well experienced loss circulation while drilling 9-7/8" hole at ~ 1 0,000' TVD, which ultimately resulted in loosing the BHA. This loss zone is much deeper (both actually and stratigraphically) then the planed TO for the Griner No.1 well. None the less, mud losses are possible in the area and will be watched for. There will be loss circulation material on location to treat mud losses if encountered. 2. The Anchor Point No. I well (Drilled by Socal) encountered coal gas mud log shows at a depth of 1375' tvd. There was no abnonnal pressure associated with these coal fonnations. The casing program for the Griner No.1 well plans for setting surface casing at 400' and therefore above any known coal zones. Proper drilling procedures will be followed while drilling the Griner Well No.1 including: proper tripping procedures, observing for background and connection gas, maintaining proper mud weights and monitoring the well for flow. The Griner No.1 well is expected to exhibit a nonnal pore pressure gradient over its entire interval to the proposed TO of6800' MD/TVD. Griner No.1 Hazard Analysis.doc .

If annular disposal of Griner waste at NNA is not allowed then the water based mud and cuttings will be hauled and stored in the Pearl NO.1 Pit. The mud and cuttings would then at a later date be injected into an approved Class II Well. Oil Based contaminated cuttings will be containerized and stored at Unocal's East Forelands Delivery Facility at Nikiski until final disposition is resolved. These cuttings will either b injected in a Class II Well or hauled out of state for disposal. The Oil Based Mud will be re-used at the subsequent well. A Temporary Drilling Waste Storage Plan outlining the above has been submitted to and approved by the ADEC.
