The predicted start date for abandonment operations to begin is July 20th, 2010. It is intended that Doyon Rig 19 be to plug and abandon the well. • ConocoPhillips Alaska drilled the Nanuq #5 exploratory well in March 2002 with the goal of gaining additional information of the surrounding reservoir and geologic characteristics of the current CD4 area. The production hole was drilled, logged and then cased. The well was drilled from an ice pad, and therefore was never perforated and completed in order to move Doyon 19 before the end of the cold weather season. Prior to leaving location, a kill string was run, the casing was freeze protected, and a tree was installed on the well. - The proposed plan once Doyon 19 is on location is to circulate the diesel that is currently in the well to 9.8 ppg LSND. At this point, the well will have kill weight fluid along with proven casing /pack off integrity and competent cement. The BOP stack will then be made up and a body test performed from the blanking plug to the blind rams. It is requested at this point that CPAI be allowed to pull the tubing kill string prior to performing a full BOP test to simplify operations. - N ~ w~zL- .~ r«-« aOP ~: ~-- Once the tubing has been pulled and BOP tested, Doyon 19 will set a bridge plug in the existing 7" production casing on the Nanuq 5 well. The 7" casing will then be cut roughly 100' below the 9-5/8" surface casing and pulled to surface. A cement stinger will then be used to spot cement throughout the remaining open hole and into the surface casing. At this point the well will be effectively abandoned and sidetracking operations will begin to spud the proposed CD4-12 well. Prior to sidetracking, additional work will be performed to swap out the older Prudhoe Gen V tubing flange for the current Alpine Gen II tubing flange. Please find attached the information required by 20 ACC 25.005 (a) and (c) for your review. Pertinent information attached to this application includes the following: 1. Form 10-403 2. A proposed re-entry and abandonment program. 3. Actual surveys from Nanuq #5 4. 7" Casing Integrity Test Results 5. Wellhead Pack off Test Results 6. Mechanical Integrity Test Form Information pertinent to the application that is presently on file at the AOGCC: 1. Diagrams of the BOP equipment, diverter equipment and choke manifold lay out as required by 20 ACC 25.035 (a) and (b). 2. A description of the drilling fluids handling system. 3. Diagram of riser setup. • If you have any questions or require further information, please contact Ryan Robertson at 265-6318 or Chip Alvord at 265-6120.

Winfree ATO 1706 Jack Walker ATO 1740 Lanston Chin Kuukpik Corporation • ti The Nanuq well was drilled as an exploration/delineation well wed' early in the development of the Alpine field. It was drilled as a slant hole with a maximum inclination of approximate 58° through most of the potential hydrocarbon bearing sands in the area. According to information in the well file the well did not reach the Alpine sands. CPAI now proposes to abandon the well and drill a sidetrack for a several thousand foot horizontal injector into the Alpine C sand. Since the existing well did not penetrate the Alpine sands it could not be used for this purpose. Drilling the sidetrack will preserve the potential to do future plug backs and sidetracks to develop potential reserves in the shallower sands. `~r~, . ~ i , ~~~ . Page 1 of 1 Schwartz, Guy L (DOA) From: Robertson, Ryan G [Ryan.G.Robertson@conocophillips.com] Sent: Thursday, July 08, 2010 11:42 AM To: Schwartz, Guy L (DOA) Subject: Nanuq #5 Sundry Permit and CD4-12 PTD Attachments: Nanuq P&A - 7.08.10.pdf Guy, As we discussed verbally, CPAI proposes to make the following adjustments to the filed Nanuq #5 Sundry to Abandon permit application and CD4-12 permit to drill application: • For the Sundry permit to abandon Nanuq #5, after step 16 listed in the Rig Procedure, Doyon 19 will run a storm packer into the 9-5/8" casing. At that point, a 2,500 psi pressure test for 10 minutes will be pertormed to insure wellbore integrity. By doing so, the wellbore will have kill weight fluid and the storm packer as well control barriers. For the CD4-12 permit to drill application, this step will be inserted after step 14 in the Rig Procedure. • Regarding the request to only body test the BOP prior to pulling the 4-1/2" tubing, CPAI would like to withdraw this request. Instead, once the BOP is initially nippled up (step 8 on Sundry permit, step 6 on permit to drill), a full BOP test using a 4-1/2" test joint will be performed against a blanking plug. This will negate step 11 in the Sundry permit and step 9 in the Permit to drill. • After the 7" casing has been cut, and the casing cutter pulled from the hole, the top pipe rams will be swapped out to 7" casing rams and pressure tested to 250 / 3,500 psi and the annular preventer to 250 J 2500 psi. This will take place after step 14 on the sundry to abandon and step 12 on the permit to drill. Regarding the pool scan for the Alpine C reservoir, there are 3 wells that fall within %4 mile of the proposed CD4- 12 wellplan -CD4-319, CD4-215 and CD4-214. These three wells have been drilled and completed in pools ap shallower than the Alpine C - Kuparuk and Nanuq formations. The CD4-24 wellbore is the closest in pool to the 1~~~roposed CD4-12 injector at 3,816 ft away. All four wells had successful intermediate cement jobs, with full returns throughout, the plugs bumping and floats holding. As per our conversation, an updated schematic for the sundry permit of the Nanuq #5 wellbore has been attached to better illustrate its condition after the well has been plugged and abandoned. The schematic now includes the cement on top of the HES second stage cementing tool, as well as the 1gt stage shoe track. Both of these cement plugs are still in place as they were never drilled out after the cement job.

The Wellhead inspection will show up in the wells group report and should be submitted as part of the pre-rig work for the sidetrack. The S/T will also automatically take Nanuq #5 off our suspended well list. Additionally, the new well CD4-12 will have the original API # plus -01 on it. No way to get around this...

The Nanuq 5 well is currently a suspended well that requires annual inspection and sundry applications for suspension as per AOGCC regulations. The deadline for the next inspection on Nanuq 5 is September 30th How do we handle the sundry approval for the suspended Nanuq 5 well considering we are going to permanently abandon it and close out the name as per our conversation earlier this week?

It will also include a request to re-enter a suspended well. I don't see any issues with renaming the surface slot to CD4-12. From what I can tell the original well was suspended properly and no further downhole cement plugs will be needed besides the kickoff plug. I assume you will be setting a CIBP in the 7"just below the cut depth after pulling the tubing. Give me a phone call and we can discuss further.

The Nanuq #5 was drilled in 2002 and never completed due to time restrictions. The plan forvvard is to recover Nanuq #5 slot and drill CD4-12. In order to do so, a bridge plug will be set at 110' MD below the surface shoe in the 7" intermediate casing. From there, the 7" casing will be cut and pulled from the well, and cement plug will be spotted back into the existing surface casing. The next step will be to run in with an 8.5" intermediate BHA and sidetrack a new well off the cement plug. I have two questions regarding the permitting for this well that I would like to discuss when you have a chance: • Firstly, we would like to send over the wells group to perform a system integrity test on the well prior to the rig arriving. They will check the integrity of the wellhead, casing, pack offs and lock down screws. Do we require a sundry permit for this work? . We would also like to close off the Nanuq #5 well name and call this well CD4-12 when it has been drilled and completed. Will that require a 10-403 Suspend permit? I have attached the shut down permit from 2003, along with a schematic of the final wellbore. Please give me a call when you have a chance to discuss.

MURKOWSKI, GOVERNOR 333 W. 7fH AVENUE, SUITE 100 ANCHORAGE, ALASKA 99501-3539 PHONE (907) 279-1433 FAX (907) 276-7542 June 26, 2003 Mr. Chip Alvord Drilling Team Leader ConocoPhillips Alaska, Inc. PO Box 100360 Anchorage Alaska 99510 In Re: Nanuq 5 (PTD 202-042) Dear Chip: In ,early 2002, ConocoPhillips drilled the Nanuq 5 exploration well. The well was cased with cement plugs left in the casing and tubing hung such that subsequent plugs could be set if the well were to be abandoned. In the original documents submitted July 25, 2002, it is stated "Nanuq 5 was suspended on April 5, 2002 for future development potential." In assessing your June 12, 2003 request for a time extension to an operations shutdown, we have examined the file. Based on our review of the well history, we conclude that the correct well status for Nanuq 5 (202-042) as of April 5, 2002 was Suspended. Accordingly, we are editing our records to reflect the well status and effective date. The consequence of this action is that all well records for Nanuq 5 become eligible for release to the public May 5, 2004. Please contact me at 793-1250 or Steve Davies at 793-1224 if you have any questions. Sincerely, ~~~ Sr. Petroleum Engineer TEM \.jj c ) Opinion Concerning Correct Status of the N anuq #5 Well A comparison of the drilling records with the Summary Drilling Procedure in the permit to drill application indicates the operator accomplished the permitted drilling program: the well was drilled to the permitted TD; casing (7") was set as deeply as hole conditions allowed; two down-hole cement plugs were set; tubing was run to facilitate placing additional shallow cement plugs. An email fromVemJohnson.Phillips Drilling Engineer, dated May 2, 2002 terms the operations on Nanuq 5 "suspension operations." The cover letter for a Sundry Well Operations report received July 25,2002 states: "N anuq 5 was suspended on April 5, 2002 for future development potential." The well was not tested, and there is no mention of testing in the Summary Drilling Procedure included in the Permit to Drill application, in the Sundry Well Operations report, or any of the operator's subsequent email messages on file with the Commission. Regulation 20 AAC 25.072 (a) states: "If circumstances prevent the continuation of the program approved on a permit to Drill (From 10-401), or if an operator wishes to change drill rigs, the operator shall apply to the commission for approval to shut down drilling or completion operations temporarily." This regulation clearly does not apply, because the objectives of the permitted drilling program were achieved; "circumstances" did not prevent continuation of the program; and operations were not halted to allow the operator to change drilling rigs. The well was never perforated, testing is not part of the approved drilling plan, and there is no stated intent to test the well in the foreseeable future. "Suspend" is defined in AOGCC's regulations as "...to plug a well in accordance with 20 AAC 25.110 and to reserve the option later to re-enter and (A) redrill the well; or (B) complete the well as an oil, gas, or service well...". The current condition of the well meets the criteria for a suspended well. The condition of the well and all indications in emails from the Operator's drilling engineer suggest they intended to plug and abandon the well, and not resume operations on it. The cover letter to the Application for Operational Shutdown Extension, received June 13, 2003, states the well is a "delineation" well that is "being retained for development of either the Nanuq or Kuparuk horizon...". This still meets the criteria of 20 AAC 25.110 (B), above, indicating that the status of this well is most properly "Suspended," and that the original classification of the well status as "Operational Shutdown" was incorrect. Accordingly, the correct well status is Suspended as of April 5, 2002, which agrees with the Operator's cover letter to the Sundry Well Operations report received July 25, 2002. The date of suspension triggers the 30-day filing period followed by the 24-month confidentiality period. This sets the release date for the Nanuq 5 well file and associated data at May 5,2004. Steve Davies ~ Nanuq 5 (202-042) Well Status ) SLtbject: Nanuq 5 (202-042) Well Status Date: Tue, 17 Jun 2003 11 :39:19 -0800 From: Tom Maunder <tom_maunder@admin.state.ak.us> To: Steve Davies <steve_davies@admin.state.ak.us> Steve, I have placed a 403 in your box that requests a time extension for this well. The well is presently carried as operation SO in our records. It appears from the well file that PPCo originally applied to have the well suspended and that Cammy changed that to ops SO. Based on the file information, PPCo did accomplish what they intended to do. The well was intended to be drilled and suspended or abandoned. When the 7" casing was set, it was cemented in a 2 stage operation. PPCo left 5 bbl of cement on top of the stage tool closing plug. They then ran tubing to below their surface casing shoe so the well could be abandoned without a rig if desired. The well is secure and based on our discussion of the Tyonek B-3 of last week, I am asking for your opinion on this well. It appears that based on what we talked about and determined on B-3 that suspended would apply to this well too. It has no perfs, and there is a mid well plug in the wellbore. Changing the well to suspended would establish the suspension date as roughly a year ago. This will not effect the release date (in the short term), but will establish a potential release date in roughly a year. Thanks in advance for your assistance. I put the file in your confidential box.

After leaving the hole open for several days of logging we have made a cleanout run and encountered tight hole at and below 11378' MD while running in, and tight hole up to 10600' md on the trip out (HRZ top at 10980' MD). TO for the well is 11735' MD. There were no significant sands in the Kuparak interval (top @ +/-11608 MD). The Nanuq interval came in close to expected depth (9950' MOto 10220'MO). Because the tight/sticky interval is below the base of the Nanuq, and there were no other signs of significant sands below the Nanuq, we are considering running and cementing the 7" casing string above the open hole TD, to +/- 11600' MO. This will provide cement isolation through the Colville shales. and will leave mud between the shoe and TD. Please confirm that this is sufficient isolation for AOGCC purposes.

This is similar to what was employed at the Hansen. "Equipping" the well as you describe should enable you to meet the State's requirements for P&A without having to move a rig on. Good luck.

("Phillips") for an order granting an exception to the spacing requirements of Regulation 20 AAC 25.055 (a)(l) to provide for the drilling and testing of the 1'{anuq #5 exploratory well to a bottom hole location that is closer than 500 feet to a property line. IT APPEARING THAT: ) Conservation Order No. 466 ) ) Nanuq #5 ) Exploratory Well ) ) March 13,2002 ) ) 1. Phillips Alaska, Inc. ("Phillips") by letter dated January 29, 2002, and received by the Commission on January 30, 2002, has requested an order allowing a spacing exception in accordance with 20 AAC 25.055 for the proposed Nanuq #5 exploratory oil well. The locations of prospective test intervals within this well may fall within 500 feet of a property line, which is also the exterior boundary of the Colville River Unit. ' 2. The Commission published notice of opportunity for public hearing in the Anchorage Daily News on February 4, 2002, pursuant to 20 AAC 25.540. 3. No protests to the application were received. FINDINGS: 1) The surface location of the well is 2895' FNL, 102' FEL, Section 24, TIIN, R4E, U.M. The projected Nanuq target location is 4518' FNL, 3043' FEL, Section 30, Tl1N, R5E, U.M. (inside the Colville River Unit). The projected Kuparuk target location is 460' FNL, 2650' FEL, Section 31, TIIN, R5E, U.M. (outside the Colville River Unit). The projected bottom hole location for this well is 607' FNL, 2603' FEL, Section 31, TIIN, R5E, U.M. (outside the Colville River Unit). 2) Rule 3 of Conservation Order 443, which governs well spacing within the Colville River Unit applies only to development wells, and not to the proposed Nanuq #5 exploratory well. 3) An exception to the well spacing provisions of20 AAC 25.055 (a)(I) is necessary for the drilling of this well. ) Conservation Order No. 466 March 14, 2002 Page 2 of 2 CONCLUSION: ) Granting a spacing exception to allow drilling of the Nanuq #5 exploratory well promotes efficient exploration and development, and will not result in waste nor jeopardize correlative rights. NOW, THEREFORE, IT IS ORDERED: Phillips's application for exception to the well spacing provisions of 20 AAC 25.055 (a)(I) for the purpose of drilling and testing the Nanuq #5 well is approved. The Nanuq #5 well may nqt be placed on regular production until the, Commission takes additional action, upon petition, and after notice and hearing, to offset any advantage Phillips may have over other owners by reason of drilling N anuq #5 to the exception location and to allow affected owners to produce their just and equitable share of hydrocarbons. Such Commission action may include establishing a new drilling unit and providing for the pooling of separately owned properties within the drilling unit.

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. Annular disposal has not been requested as part of the Permit to Drill application for Colville River Unit Nanuq #5. 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. 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.

Nanuq #5 will be drilled from a 500' x 500' ice pad located approximately 3.8 miles South by Southwest of Alpine. The well is designed to penetrate ttu::et:rQñ the Nanuq, Kuparuk, and Alpine sandstone horizons. At the conclusion of c drilling and evaluation operations, Nanuq #5 will either be temporarily suspended or plugged .,/' and abandoned (P&A'd). The temporarily suspended Nanuq #5 will await the possible development of an Alpine satellite pad at its location. Before suspension operations commence, an Application for Sundry Approvals (Form 10-403) w,ill bè submitted in accordance with 20 MC 25.110 (b). Nanuq #5 will be P&A'd at the conclusion of drilling operations or at a future date if ' development of this pad does not go forward. Before P&A operations commence an Application for Sundry Approvals (Form 10-403) will be submitted in accordance with 20 MC 25.1 05(e). There will be a temporary storage area for drill cuttings on the ice pad. All cuttings will be ( hauled to the Prudhoe Bay Field for temporary storage and eventual processing for injection down an approved disposal well. Waste drilling mud will be hauled to an Alpine Class II disposal well or to a KRU Class II disposal well. / There are no shaltow hazards expected at Nanuq #5. For the Shallow Hazards Analysis, the local compaction trend and the translation trend model were applied to velocities from 3D seismic data to predict pore pressures. The predictions show no apparent shallow hazards or large pressure anomalies at the proposed well locations.. See discussion under "Drilling Area Risks" and the attached Shallow Hazards Analysis. Note that Phillips does not anticipate the presence of H2S in the formations to be encountered in j this well; however, there will be H2S monitoring equipment operating, as is the usual practice while drilling wells in the Colville River Unit.

Rig dawn and move off Doyon 19. Well Proximity Risks: ) ) DrillinQ Area Risks: There are no well proximity risks associated with Nanuq #5. With the close proximity of Alpine to Nanuq #5 (approximately 3.4 miles to the northwest), and with the development drilling on Alpine's CD1 and 2 pads, a wealth of knowledge in local formation properties has ~n gained. No shallow hazards were evident during the development drilling on CD1 and CD2 Pads at Alpine. The mud weights outlined in the "Drilling Fluid Program" for Nanuq #5 will be consistent with the mud weights used to drill the Pilot Hole on well CD1-NQ1 where neither pressure anomalies nor lost circulation were encountered. The pilot hole on CD1-NQ1 targeted the same Nanuq, Kuparuk, and Alpine horizons as the Nanuq #5 well plan targets. Examination of the drilling and testing data from offset wells Nanuk #1, Nanuk #2 and Nanuq #3 suggest no /' shallow hazards are present. presyure data from the RFT's indicates a formation pressure gradient of approximately 0.444 psi/fl:. A 9.2 ppg mud is sufficient to provide a 232 psi overbalance margin f~ the Nanuq, formation and a 150 psi overbalance for the Alpine formation. The planned mud weight of 9.8 ppg is more than- adequate for drilling the reservoir sections; however, it is required for shale stabilization of the HRZ. The surface locations of Nanuq #1 and #2 and #3 are within 5,000' of the surface location of Nanuq #5. /'" The seismic shallow hazards analysis indicates no abnormal pressures or weak formations; particularly at shallow depths.

Keep flowline viscosity at :!: 200 sec/qt while drilling and running casing. Reduce viscosity prior to cementing. Maintain mud weight < 9.6 ppg by use of solids control system and dilution where necessary. Intermediate Hole Section: Fresh water gel I polymer mud system. Ensure good hole cleaning by pumping regular sweeps and maximizing fluid annular velocity. Maintain mud weight at or below 9.8 ppg. If connection gas is encountered weight up mud one to two tenths of a pound per gallon. Be prepared to add loss circulation material if loss zones are encountered. Good filter cake quality, hole cleaning and maintenance of low drill solids (by diluting as required) will all be important in maintaining wellbore stability. PRESSURE INFORMATION AND CASING DESIGN (per 20 ACC 25.005 ( c) (3,4) and as required in 20 ACC 25.035 (d) (2» ) ') The following presents data used for calculation of anticipated surface pressure (ASP) during drilling of this well: Casing Size Csg Setting Fracture Pore pressure ASP Drilling (in) Depth Gradient (Ibs.

Test BOP's to 5000 psi. ./ PROCEDURE FOR CALCULATING ANTICPATED SURFACE PRESSURE (ASP) ASP is determined as the lesser of 1) surface pressure at breakdown of the formation casing seat with a gas gradient to the surface, or 2) formation pore pressure at the next casing point less a gas gradient to the surface as follows: 1) ASP = [(FG x 0.052) - 0.1]D Where: ASP = Anticipated Surface pressure in psi FG = Fracture gradient at the casing seat in Ib./gal 0.052 = Conversion from Ib./gal to psi/ft 0.1 = Gas gradient in psi/ft D = true Vertical depth of casing seat in ft RKB OR 2) ASP = FPP - (0.1 x D) Where; FPP = Formation Pore Pressure at the next casing point 1. ASP CALCULATIONS Drilling below conductor casing (16") ASP = [(FG x 0.052) - 0.1] D = [(12.9 x 0.052) - 0.1] x 114 = 65 p~i OR ASP = FPP - (0.1 x D) = 1110 - (0.1 x 2452') = 864 psi Drilling below surface casing (9 5/8") 2. ASP = [(FG x 0.052) - 0.1] 0 = [(11.8 x 0.052) - 0.1] x 2452 = 1259-psi OR ASP = FPP - (0.1 x D) = 3290 - (0.1 x 7117) = 2578 psi / CASING PROPERTIES Wt OD (ppf) Grade . . ..... 1"'" ... .. 9-5/8" 36 J-55 7" 26 L-80 Range 3 3 Wt OD (ppf) Grade Range ~,,,,,..,,,,,,,-.,,...,,;,;, ,...""."""~"''''',.,,'',,. .. ..... .., .""", ",.,.~ 9-5/8" 36 J-55 3 7" 26 L-80 3 Casing Setting Depth Rational 16" -114' RKB 9-5/8" - 2452' TVD' RKB 7" -7117 TVD' RKB ) Connection Type BTC BTC-Mod Connection Type BTC BTC-Mod Collapse psi 5,410 psi 85% of Collapse .1717 psi 4.599 psi ) Burst 3520 psi 7,240 psi 85% of Burst 2992 psi ,6.154 psi I TENSILE STRENGTH JOINT BODY 453k Ibs. 564k Ibs 364klbs 415klbs Conductor Casing to provide sufficient anchor and fracture gradient for diverter system.

A local compaction trend and a local velocity to pressure gradient translation trend model were established using control from surrounding area wells. The local compaction trend and the translation trend model were applied to velocities / from 3D seismic data to predict pore pressures. The predictions show no apparent shallow hazards or large pressure anomalies at the proposed well location. Seismic Processinq The accuracy of seism ic geopressure analysis depends critically on the accuracy of the input velocity field. The velocities used for pressure prediction were generated using Phillips' A VEL software, an automated high-resolution velocity analysis program developed by ARCO Exploration and Production Technology. This process produces a very accurate velocity field defined at every sample in time and laterally along each seismic line. The output RMS velocities were smoothed over 9 CDPs to minimize instabilities in the velocity field that might result from noise, lack of signal or variations in CDP fold. ') ) Pressure Prediction Procedure Phillip's PPFG software (developed by ARCO Exploration and Production Technology) was used to calculate the predicted pore pressures. The Nanuk #3 offset well was used to establish both a local normal compaction trend line and local velocity vs. pressure translation trend model. The model matches the model used for previous pressure prediction work in this area (Heinlein 2000). The model is similar to the models used for previous pressure prediction projects at Alpine, NPRA, and Tarn. The Nanuq #5 well will be drilled approximately 300 ft from the surface location used to drill Nanuq #3 in 2001. No shallow hazards were encountered while drilling Nanuq #3. Procedure 1.) A Normal Compaction Trend Line (NCTL) was determined for a cube of seismic lines from the Colville 3D seism ic dataset. The slope of the seism ic-derived NyTLs matched the slope of the NCTL calculated at Nanuk #1 and Nanuq #3 (-5e-5). The intercept of the NCTL varied slightly on the seismic data (175) from the intercept observed at the Nanuq #3 well (165). 2.) The difference between interval transit times (ITT), recorded by wireline sonic logs (il T) in the existing wells or by seism ic velocities in the proposed wells, and the Interval transit times predicted by a downward extension of the NCTL were measured. These values are the travel time differences, MT. 3.) A translation trend model was established by comparing transit time differences (ilil T) to mud weights. This model calculates pressure gradients (PP) using the equation PP = C2*ililT**2 + C1*ôilT + CO Where C2 = 8.01~-5, C1 = .0019, CO ~ .465 / 4.) Fracture gradients were calculated using the Eaton Method. Inputs are the bulk density, the calculated pore pressure gradient profile, and a Poisson's Ratio profile. ) ) Seismic Pore Pressure Prediction Pressure gradients werejPredicted for the Nanuq #5 proposed well location using a cube of 3D seismic data surrounding the proposed borepath. The proposed borepath is located at the edge of two 3D surveys: the borepath is located close to the edge (but entirely within the bounds of) the Colville 3D survey. The deeper half of the proposed borepath falls within the bounds of the Nanuq 3D survey (Figure #1). Velocity data from both surveys was used in the pressure analysis; velocities in the' portion of the borepath that fell within both seismic surveys were close in value and yielded simuar pressure predictions. All figures included here were calculated using velocity data from the Colville 3D survey. Pressure gradient prediction displays are provided for the following seismic lines, both in time and in depth.

No overpressured zones were found within the cube of 3D data surrounding the / proposed borepath trajectory. No apparent shallow hazards are observed in the seismic pressure analysis.

There are no apparent shallow hazards at the proposed Nanuq #5 well location, and no zones of overpressure along the proposed Nanuq #5 borepath trajectory. 2.) Overpressure was not encountered in the Nanuq #3 well, which was drilled from the same surface location. Overpressure was not encountered in other wells drilled previously in this area (Nanuk #1 and Nanuk #2). ./ / 3.) The normal compaction trend observed in the Nanuq #3 well matches compaction trends observed in other area wells (Alpine and NPRA) and matches trends observed in the seism ic datasets used for pressure analysis.
