After drilling to the target specified in the original APD and reviewing the LWD logs obtained across the Kuparuk producing interval, it was found that the Kuparuk sands in this area exhibited virtually no porosity, making the well unsuitable for completion as a producer. This well will be suspended as shown in the attached wellbore schematic by laying 15.8 ppg 'Class G' cement across the entire open hole interval below the 7" intermediate casing shoe and running a 3-1/2" tubing kill string to 2164' MD. The competency and location of the top of the plug will be mechanically confirmed by tagging the cement with the BHA and then applying 20 klbs of sustained downweight. A 5000 psi tree will be installed on the well 'and a back pressure valve (BPV) will be set in the wellhead. The well will then be freeze protected by displacing with diesel to below the base of the permafrost. Tom Maunder gave verbal approval for the above operation. Phillips Alaska is requesting this temporary shutdown in order to allow time to properly identify an alternative sidetrack target and prepare the appropriate directional plans and permits. If you have any questions or require further information, please contact Todd Mushovic at (907) 265-6974 or Paul Mazzolini at (907) 263-4603.

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 s .ynopsis 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 Kupamk River Unit Well .No. Silvertip (1 J-14). Please note that any disposal of fluids generated from this drilling operation which are pumped down the surface/production casing annulus of a well approved for annular disposal on Drill Site 1J must comply with the requirements and limitations of 20 AAC 25.080. Approval of this permit to drill does not authorize disposal of drilling waste in a volume greater than 35,000 barrels through the annular space of a single well or to use that well for disposal purposes for a period longer than , one year. 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.

The well is designed to penetrate and further develop the production potential of the Kuparuk sands in the vicinity of 1J Pad. In the event the Kuparuk interval is not sufficient to complete, the possibility exists that the wellbore would be evaluated as a potential West Sak producer. The well is designed as a conventional producer and is planned for a 9-5/8" surface casing string, a 7" intermediate string set in the HRZ above the Kuparuk interval, and a 3-1/2" production liner set thru the Kuparuk sands. The well will be drilled and completed using Nabors 16E. Completion plans call for running a 3-1/2" gas lift production tubing string. Attached is the information required by 20 ACC 25.005 (c) for your review. There are no shallow hazards expected at Silvertip (see attached graphs). The nearest offset wells indicate no overpressured intervals or lost circulation zones. There will be no reserve pit for this well. Waste drilling mud will be hauled to a KRU Class II disposal well or disposed of in an approved annulus on 1J. If a production casing string is set in this well Phillips requests that the Silvertip well be permitted for annular disposal of fluids occurring as a result of drilling operations, per regulation 20 AAC 25.080. As in the past Phillips would submit a 10-403 Form to the Commission with the appropriate technical information. If this well is tested, the produced fluids will either be hauled to Kuparuk for recycling or injection into an appropriate disposal well or the produced fluids will be reinjected into the Silvertip wellbore.

Maximum Anticipated Surface Pressure: Two possibilities exist for the possible maximum anticipated surface pressure (MASP) seen by the surface casing string along the Silvertip well path. 1) MASP can be calculated using an expected leak-off of 13.1 ppg EMW (0.68 psi/ft) and a gas gradient of 0.11 psi/ft. This shows that formation breakdown would occur at a surface pressure of 2403 psi. The leak off EMW was chosen based on average open hole LOT's seen while drilling the EBA wells off 1D Pad. MASP = (4215 ft)(0.68-0.11) - 2403 psi RECEIVED Alaska Oil & Gas Cons. Commission Anchorage Phillips Alaska, Inc. will test the BOP equipment to 5000 psi prior to drilling out of surface casing. The current plans are to topset in the HRZ above the Kuparuk. The maximum anticipated pressure for the intermediate casing string would be 3120 psi as calculated previously. Phillips Alaska, Inc. will test the BOP equipment to 5000 psi prior to drilling out of intermediate casing. Based on the anticipated pressures shown, a maximum mud weight requirement for this well is established based on the potential (not expected in this wellbore) charging of the D-shale sands. Assuming a 150 psi overbalance is required to safely drill and trip in this formation, then a required mud weight of 11.4 ppg can be predicted as the maximum mud weight needed to safely conduct rig operations, assuming a TVD of 6505'. MW = [(6505 ft)(0.57)+150]/6505/.052 = 11.4 ppg Well Proximity Risks: There are no well proximity risks associated with Silvertip. All of the West Sak Pilot wells have been plugged and abandoned. The nearest abandoned well is 126' away at a MD of 1433'. 1J-03 was recently drilled at the northern end of the pad 655' away and was drilled to the northeast while Silvertip will be drilled to the southeast. 1J-09 also located at the northern end of the pad will be drilled to north. Drilling Area Risks: Risks in the Silvertip drilling area include surface interval hydrates, lost circulation, and potential borehole instability in and below the permafrost zone as well as through the intermediate shales. Hydrate risks will be minimized by the use of sufficient mud weights to allow for tripping of pipe, controlled drilling rates, and rheological properties which safely appropriate gas breakout. Lost circulation will be addressed with lost circulation material (LCM), reduced circulating rates, and reduced mud weights as needed. Shale instability will be controlled primarily with the planned fluid densities. A PWD sub will also be used to monitor ECDs and the hole cleaning effectiveness. Additional risk exists with unpredictable charging of the D-shale sands during historic gas injection. This risk is not anticipated in this section of the Kuparuk reservoir, and is further mitigated by top setting in the HRZ above the D-shale. Examination of the three nearest offset wells, West Sak #5, KRU State #2, and Rock Flour #1 in addition to the West Sak Pilot wells drilled from this pad reveal no subsurface hazards such as abnormal pressure or lost circulation zones. For the well, Silvertip, seismic analysis is plotted and pore pressure and fracture gradient curves derived. Again, no indications of abnormal pressure or weak formations were seen particularly at shallow depths. The mud weights planned for Silvertip are conservatively based on those used during drilling of the offsets including the recently drilled EBA wells off 1D Pad. Prudent and precautionary drilling/tripping techniques will be emphasized while drilling this exploratory well which is SOP for all rigs working in the Kuparuk area. The 9-5/8" surface casing shoe will be tested to a maximum 16 ppg EMW formation integrity test or leak-off (whichever is least) after drilling 20 to 50 feet of new formation. RECEIVED MAR 0 8 2.001 Annular PumDinq Operations: Alaska Oil & Gas Cons. Commission Anchorage Incidental fluids developed from drilling operations will be either injected into an approved annulus on the same pad (none available at 1J Pad) or hauled to the nearest permitted Class II disposal well. (Note that cement rinseate will not be injected down the dedicated disposal well but will be recycled or held for an open annulus.) The open annulus will be left with a non-freezing fluid during any extended shut down (> 4 hr) in pumping operations. The Silvertip surface/production casing annulus will be filled with diesel after setting production casing and prior to the drilling rig moving off of the well. If isolation is required per regulations over significant hydrocarbons, then sufficient cement volume will be pumped during the production cement job to cover those formations. At the end of drilling operations, a request for Silvertip to be permitted for annular pumping of fluids occurring as a result of future drilling operations on 1J pad, per regulation 20 AAC 25.080, will be submitted. Any zones containing significant hydrocarbons will be isolated prior to initiating annular pumping. There will be no USDW's open below the shoe or potable/industrial water wells within one mile of the receiving zone. Reference the enclosed directional drilling plan for other formation markers in this well. Surface casing will be set in the Cretaceous shales below the base of the West Sak Sands. These 300-500' thick shales are part of the Colville Group and are known to provide vertical barriers to fluid flow. The surface casing shoe will be set a minimum of 100' vertically below the base of the West Sak into the heart of the shales. Surface casing will be cemented back to surface to allow further protection to any possible fresh water zones. The surface and production casing strings exposed to the annular pumping operations have sufficient strength by using the 85% collapse and burst ratings listed in the following table: Wt Connection 85% of 85% of OD (ppf) Grade :Range Type Collapse Collapse Burst Burst 9-5/8" 36 J-55 3 BTC 2,020 psi NA 3,520 psi 2,992 psi 7" 26 L-80 3 BTCM 5,410 psi 4,599 psi 7,240 psi 6,154 psi 3Y2"* 9.3 L-80 2 SLHT 10,530 psi 8,951 psi 10,160 psi 8,636 psi *ifneeded Fluids to be disposed of in the annulus will be limited to drilling wastes associated with drilling a well as defined in 20 AAC 25.080 (h).

FIT TEST PROCEDURE Kuparuk River Unit (KRU) EBA Operations/Silvertip After cementing casing and nippling up BOPE, RIH to top of cement and pressure test the casing to the test pressure specified in the well plan (usually 3000 psi or 3500 psi) for 30 minutes and record on chart (AOGCC required casing integrity test). Record the information on the PAl LOT form (you can locate on the drilling web page). Plot Casing Pressure Test (volume vs. pressure and time holding pressure on casing). Verify that the test indicates a linear line and that there is no air entrained in the mud. Repeat Casing pressure test if needed. 2. Drill 20' of new hole below the casing shoe. Circulate the hole to establish a uniform mud density throughout the system (required for a good FIT or LOT). PU into the shoe. 4. Close the blowout preventer (ram or annular). 5. Pump down the drill stem at 1/4 to 1/2 bpm. . On the LOT form, plot the fluid pumped (volume or strokes) vs. drill pipe pressure until the formation begins to take fluid; at this point the pressure will continue to rise, but at a slower rate. Note: If 16.0 ppg EMW is reached, shut down and hold the pressure there. This becomes the data for a formation integrity test (FIT) instead of a LOT 7. At leak off pump 3 bbls of mud into formation prior to shutting down the pump. . Shut down when the leak-off point is clearly seen and 3 bbls of mud has been pumped into the formation. Record initial shut-in pressure. With the pump shut down monitor, record and report the shut -in pressures for a minimum of 10 minutes or until the shut -in pressure stabilizes. Record time vs. pressure in 1-minute intervals and plot information. Bleed the pressure off and record the fluid volume recovered. Forward the data to the Drilling Engineer in Anchorage. The Drilling Engineer will forward the information to the Agencies. 1 8/4/00, v2 Silvertip PRESSURE ANALYSIS AND PREDICTION (Per 20 ACC 25.005 (c) (9); 20 ACC 25.033 (f); and 20 ACC 25.061 (a)) DISCUSSION: An analysis and prediction of overpressured strata was performed for the Silvertip well as required by AOGCC regulations. Phillips does not expect to encounter abnormal pressure from any zones. The prediction is based on an evaluation of offset wells West Sak #5, KRU State #2, Rock Flour #1 and two of the West Sak Pilot wells #14 & #13. Attached are the following: · Mud weight versus depth graph for these wells. · Seismic analysis for Silvertip. Pore pressure, frac pressure and anticipated mud weight graph. · See attached comments regarding the seismic data interpretations. · As required by Phillips internal SOP's, a pre spud meeting will be held prior to spudding the Silvertip well to discuss all potential drilling hazards.

This report reflects the latest revision of the Silvertip #1 well plan and replaces the initial pressure prediction report dated November 2000. A local compaction trend and a local velocity to pressure gradient translation trend model were established using control from the W Sak 5 and W Sak Pit 81 wells. The local compaction trend and the translation trend model were applied to velocities from 3D seismic data to predict pore pressures. No shallow hazards or potential high pressure zones were observed intersecting the proposed borepath. Drillincl History The Silvertip #1 well will be drilled from the 1J Pad located in the southwestern corner of the Kuparuk River Field. A number of shallow wells have been drilled from this same surface location and none have encountered abnormally high pressures. Wells have been drilled in close proximity to the west of 1J Pad (Kup 34-11-10-1), south (W Sak 5, KRU State 2), and east (Rock Flour 1) also with no abnormal pressures encountered (Figure 1). Seismic Processinq The accuracy of seismic geopressure analysis depends critically on the accuracy of the input velocity field. The velocities used for pressure prediction were generated using Phillips' AVEL 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. Tests run on the Silvertip velocity field to refine the velocities calculated by AVEL to ensure the most accurate velocity calculation possible showed evidence of improvement in velocity calculations, and the velocity volume used for pressure prediction was updated based upon these results. In addition to refining the AVEL calculations, seismic gathers were inspected visually and via semblance calculations in the area surrounding potential pressure anomalies. It should also be noted that the maximum far offset for the Kuparuk 3D dataset in the study area is limited to 5115 ft. This parameter will decrease the resolution of RMS velocity determination. Pressure Prediction Procedure Phillip's PPFG software (developed by ARCO Exploration and Production Technology) was used to calculate the predicted pore pressures. The W Sak 5 offset well (Figure 2) was used to establish both a local normal compaction trend line and local velocity vs. pressure translation trend model. This model was compared to models calculated for other area wells (W Sak Pit 81, Rock Flour 1, KUP 34-11-10_1, KRU State 2) and found to be a good match. Procedure 1 .) A Normal Compaction Trend Line (NCTL) was determined for a cube of seismic lines from the KRU3D seismic dataset. The slope of the individual seismic NCTLs matched the slope calculated at the W Sak 5, but the intercepts varied slightly from the W Sak 5 NCTL. This is not unexpected as the seismic velocity measures a larger component of horizontal velocity vs the well sonic log which measures primarily vertical velocity. The regional well NCTL has a slope of 181; the seismic lines have an average slope of 196. The slope of the NCTL line is -4.9'5. 2.) (AT) in the existing wells or by seismic 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,/tAT. 3.) A translation trend model was established by comparing transit time differences (/t/tT) to mud weights. This model calculates pressure gradients (PP) using the equation PP = C2*/t/tT**2 + CI*AAT + 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 (from a West Cameron model). Location Map A basemap showing the plan view location of the Silvertip #1 borepath and offset well locations is shown in Figure 1. W Sak 5 Figure 2 is the pore pressure gradient calculation for the W Sak 5 well. The left side is the wireline sonic DT (black curve) with the NCTL (red line). The right side is the pore pressure gradient calculation (blue curve), actual mud weight (green curve), and the calculated fracture gradient (red curve). Casing points, formation tops, and lithology changes are as labeled. Seismic Pore Pressure Prediction Pressure gradients were predicted for a cube of 3D inlines and xlines surrounding the proposed Silvertip deviated borehole. The pressure gradient prediction for a 3D traverse along the proposed borepath is presented in Figure 3. The yellow line on Figure 3 is the projected borepath. The red line represents a fault cut. Warmer colors indicate higher predicted mud weights (pore pressure gradients). The seismic display is presented in two-way travel time, with depth values derived from the time-depth chart and table provided in Figure 4. This function is derived from checkshot data in the offset West Sak 5 well, and tie of existing wells to seismic data via synthetic seismograms. No shallow hazards or zones of abnormally high pressure are observed along the proposed borepath. Two zones of predicted increase in pressure are observed on the pore pressure profile at approximately 150 ms. (600' tvd) above the borepath. Both of these anomalies are associated with an interpreted fault zone that will not be penetrated at this depth by the Silvertip 1 well. The apparent increase in pressure noted at 512 ms (Figure 3) correlates in time with the K15 regional marker. There is a coal present at 2120 ft- 2130 ft in the W Sak Pit 81 well just below the K15. The seismic velocities at this depth appear to have two distinct trends, and it is possible that a decrease in seismic velocity here is due to the presence of a coal. If this is the case, this is a false indication of increased pressure and does not indicate a potential hazard. The increase in pressure noted at 706 ms (Figure 3) may be associated stratigraphically with the Ugnu sands. Low velocity zones are present in the Ugnu B sands (3015 ft'- 3028 ft) in the W Sak Pit 81 well, and could indicate the presence of a thin bed of gas- charged.sand. Alternatively, the localized nature of this anomaly along the interpretted fault zone may reflect irregularities in the RMS velocity field not related to changes in pore pressure. Visual inspection of the prestack seismic data shows that the seismic velocity picks in this zone between K-15 and the W Sak sands are ambiguous in some of the locations. The predicted pore pressure gradient beneath proposed Silvertip #1 surface location (seismic inline 1291/cdp 1224) is shown in Figure 5. Conclusions 1 .) The normal compaction trend calculated from the seismic data matches the trend observed in the W Sak 5 and W Sak Pit 81 wells. 2.) AVEL parameters were tested to improve the seismic velocity calculations. Based upon the results of the testing, AVEL was re-run in the area around the Silvertip #1 borepath, and the updated velocity volume was used for pressure prediction. 3.) There are no shallow hazards or zones of abnormally high pressure intersecting the proposed Silvertip #1 borepath. 4.) A zone of possible high pressure is observed approximately 600 feet above the borepath at 512 ms two-way-time. This observed pressure anomaly correlates to a coal observed in the W Sak Pit 81 just below the regional K15 marker and is not indicative of a true increase in pressure. 5.) A second zone of possible high pressure is observed approximately 600 feet above the borepath at 706 ms two-way-time. This anomaly occurs at a stratigraphic level associated with thin sands in the Ugnu Fm. penetrated at W Sak Pit 81 and may be related to some level of gas-charge associated with Ugnu coals. Alternatively, this anomaly may be related to irregularites in the velocity field along an associated fault surface. The proposed Silvertip #1 wellpath will not penetrate this anomaly. 6.) Ambiguous seismic velocity trends were observed in the area of the calculated pressure anomalies. A number of factors were found to affect the reliability of the 3D seismic velocity calculations near the proposed borepath, including Iow effective cdp fold, limited range of offsets, and smearing of seismic signal due to faults. It is doubtful that further refining of velocity calculations would be able to resolve the observed ambiguities. PHILLIPS PETROLEUM COMPANY Pore Pressure and Fracture Gradient System 02/19/2000 K.

The Department approves the plan as provided. The area where public access is prohibited under Condition 13 is not considered to be ambient air. Phillips 2000-200l Winter Drilling Program Construction Permit No.0073-AC044 Final January 19, 2001 Page 18 Surveillance Plan for Air Permitting Exclusion Zones Phillips Alaska Inc. (PAI) 2000-2001 Winter Exploration Drilling Operations Background: The previous Alaska Department of Environmental Conservation (ADEC) Air Quality Construction Permits for North Slope onshore winter exploration drilling operations have called for preparation and submission of a surveillance plan associated with the air exclusion zones that will be utilized by PAI for this winter's exploration drilling operations. Per last season's permits: "To prevent public access: a. Post the area with lighted signs printed in English and Inupiat which indicate that No Trespassing; Restricted Entry. Place signs on the ice road leading to the well pad, and at least one on each side of the pad at the ambient air boundary. For pads where a boundary of 250 meters from the pad edge is required, at least two signs must be placed along each side. b. Maintain surveillance over the area sufficient to ensure that the public is excluded. Follow the surveillance plan in Exhibit C." Proposed Sign Construction and Placement: PAI proposes to utilize signs that are either lighted or have been constructed of reflective material. These signs will be the same ones used in previous years. For locations which require a 194 meter exclusion zone from the pad edge, PAl proposes to place one sign on the ice road leading to the well pad at the ambient air boundary and at least one sign on each other side of the pad at the ambient air boundary. For locations which require a 334 meter exclusion zone from the edge of the pad, PAI proposes to place at least two signs along each side of the pad at the ambient air boundary. Surveillance Plan Personnel: PAI's surveillance plan personnel for the various onshore winter exploration drilling projects will vary by location. For the Fiord, Alpine West, Nigliq, and Palm operations, PAI will have full time polar bear monitors due to the proximity of these sites to the coast. Hence, for these wells, PAl will utilize polar bear monitors to watch for entry of unauthorized personnel in addition to their polar bear duties. For all other operations, PAI will utilize the forklift driver, the roustabout crews, and technicians from Alaska Clean Seas to perform surveillance duties. Phillips 2000-2001 Winter Drilling Program Construction Permit No.0073-AC044 Final January 19, 2001 Page 19 Additionally, for all operations, all on-site personnel will be informed of the air permitting requirements to maintain an exclusion zone at the location. All personnel will be asked to maintain an exclusion zone at the location. All personnel will be asked to observe the location perimeter as they conduct their regular duties. Any suspected violation of the exclusion zone by unauthorized personnel shall be immediately reported to the surveillance monitoring individual by the observing party. Proposed Surveillance Actions: The designated surveillance personnel will be required to patrol the area between the pad edge and the edge of the exclusion zone at a frequency of at least every four hours or six times daily. The surveillance personnel will log the time and date of the location patrol. These logs will be recorded on the attached form. These completed forms will be maintained on location in the PAI rig supervisor's office or in another on-site location designated by the PAl rig supervisor. If the surveillance individual encounters unauthorized personnel in the air exclusion zone, the following steps will be taken by that individual: Approach the unauthorized person (or persons) and request that they leave the exclusion zone immediately. If the unauthorized individual(s) refuse to leave the exclusion zone area after the above request, they will be informed that they are subjecting themselves to an area where national ambient air quality standards may not be met and that State regulations require PAl to restrict entry to the . posted area to authorized personnel only. The unauthorized person or persons will again be asked to leave the exclusion zone area. If the unauthorized individual(s) still refuse to leave, they will be informed that neither PAI nor any State agency will be liable or responsible for any harm they may encounter by being in a restricted entry area. The surveillance individual will also request the name or names of the unauthorized personnel at that time. The surveillance individual will then log the encounter with the unauthorized person or persons on the surveillance form. The data to be logged in such a situation will include: 1) The name of the individual (if known or otherwise provided) 2) The method of entry into the exclusion zone (e.g. by foot, snow machine, etc.) 3) Duration of unauthorized presence within the exclusion zone 4) Other pertinent information as appropriate The surveillance individual will also report such incidents to the PAl rig supervisor or their designated alternate for such purposes at the next available opportunity. If unauthorized personnel entry into the exclusion zone poses safety concerns due to operational activities (e.g. the person or persons are approaching the test flare during operation, etc.), the PAI rig supervisor shall immediately be contacted by the surveillance individual. Actions will then be taken as deemed appropriate by the ?AI rig supervisor. PAl will include summary information regarding any exclusion zone violations in the facility operating report for each prospect. The completed surveillance forms will be maintained on location until completion of the operation. At that time, all completed forms should be sent to PAI's Kuparuk Field Environmental Phillips 2000-2001 Winter Drilling Program Construction Permit No.0073-AC044 Final January 19, 2001 Page 20 Compliance Coordinators (Leigh Goodin~Bruce St. Pierre, Internal Mail Address NSK 61, phone: 659-7242) for maintenance.

Maximum Anticipated Surface Pressure: Two possibilities exist for the possible maximum anticipated surface pressure (MASP) seen by the surface casing string along the Silvertip well path. 1) MASP can be calculated using an expected leak-off of 13.1 ppg EMW (0.68 psi/ft) and a gas gradient of 0.11 psi/ft. This shows that formation breakdown would occur at a surface pressure of 2373 psi. The leak off EMW was chosen based on average open hole LOT's seen while drilling the EBA wells off 1D Pad. MASP = (4164 ft)(0.68 - 0.11) = 2373 psi RECEIVED NOV 28 2000 Alaska Oil & Gas Cons. Commission ~chorage 2) If surface shoe LOT is higher than expected and the well is drilled out of surface casing to TD (not planned), the MASP can be calculated based on a reservoir pressure of 3691 psi at 6476' TVD (0.57 psi/ft) and a gas gradient of 0.11 psi/ft. In this case, MASP would occur at 2979 psi. MASP = (6476 ft)(0.57-0.11) = 2979 psi Phillips Alaska, Inc. will test the BOP equipment to 5000 psi prior to drilling out of surface casing. Nabors 14E is configured with 10,000 psi BOP equipment in order to drill the McCovey prospect which is tentatively scheduled after Silvertip. The current plans are to topset in the HRZ above the Kuparuk. The maximum anticipated pressure for the intermediate casing string would be 2979 psi as calculated previously. Phillips Alaska, Inc. will test the BOP equipment to 5000 psi prior to drilling out of intermediate casing. Nabors 14E is configured with 10,000 psi BOP equipment in order to drill the McCovey prospect which is tentatively scheduled after Silvertip. Based on the anticipated pressures shown, a maximum mud weight requirement for this well is established based on the potential (not expected in this wellbore) charging of the D-shale sands. Assuming a 150 psi overbalance is required to safely drill and trip in this formation, then a required mud weight of 11.4 ppg can be predicted as the maximum mud weight needed to safely conduct rig operations, assuming a TVD of 6476'. MW: [(6476 ft)(0.57)+150]/6476/.052 = 11.4 ppg Well Proximity Risks: There are no well proximity risks associated with Silvertip. All of the West Sak Pilot wells have been plugged and abandoned. Drilling Area Risks: Risks in the Silvertip drilling area include surface interval hydrates, lost circulation, and potential borehole instability in and below the permafrost zone as well as through the intermediate shales. Hydrate risks will be minimized by the use of sufficient mud weights to allow for tripping of pipe, controlled drilling rates, and rheological properties which safely appropriate gas breakout. Lost circulation will be addressed with lost circulation material (LCM), reduced circulating rates, and reduced mud weights as needed. Shale instability will be controlled primarily with the planned fluid densities. Additional risk exists with unpredictable charging of the D-shale sands during historic gas injection. This risk is not anticipated in this section of the Kuparuk reservoir, and is further mitigated by top setting in the HRZ above the D-shale. Examination of the three nearest offset wells, West Sak #5, KRU State #2, and Rock Flour #1 in addition to the West Sak Pilot wells drilled from this pad reveal no subsurface hazards such as abnormal pressure or lost circulation zones. For the well, Silvertip, seismic analysis is plotted and pore pressure and fracture gradient curves derived. Again, no indications of abnormal pressure or weak formations were seen particularly at shallow depths. The mud weights planned for Silvertip are conservatively based on those used during drilling of the offsets including the recently drilled EBA wells off 1D Pad. Prudent and precautionary drilling/tripping techniques will be emphasized while drilling this exploratory well which is SOP for all rigs working in the Kuparuk area. The 9-5/8" surface casing shoe will be tested to a maximum 16 ppg EMW formation integrity test or leak-off (whichever is least) after drilling 20 to 50 feet of new formation. RECEIVED NOV 28 2000 Alaska 0il & Gas Cons. Commission Anchorage Annular Pumping Operations: Incidental fluids developed from drilling operations will be either injected into an approved annulus on the same pad (none available at 1J Pad) or hauled to the nearest permitted Class II disposal well. (Note that cement rinseate will not be iniected down the dedicated disposal well but will be recycled or held for an open annulus.) The open annulus will be left with a non-freezing fluid during any extended shut down (> 4 hr) in pumping operations. The Silvertip surface/production casing annulus will be filled with diesel after setting production casing and prior to the drilling rig moving off of the well. If isolation is required per regulations over significant hydrocarbons, then sufficient cement volume will be pumped during the production cement job to cover those formations. At the end of drilling operations, a request for Silvertip to be permitted for annular pumping of fluids occurring as a result of future drilling operations on 1J pad, per regulation 20 AAC 25.080, will be submitted. Any zones containing significant hydrocarbons will be isolated prior to initiating annular pumping. There will be no USDW's open below the shoe or potable/industrial water wells within one mile of the receiving zone. Reference the enclosed directional drilling plan for other formation markers in this well. Surface casing will be set in the Cretaceous shales below the base of the West Sak Sands. These 300-500' thick shales are part of the Colville Group and are known to provide vertical barriers to fluid flow. The surface casing shoe will be set a minimum of 100' vertically below the base of the West Sak into the heart of the shales. The surface and production casing strings exposed to the annular pumping operations have sufficient strength by using the 85% collapse and burst ratings listed in the following table: Wt Connection 85% of 85% of OD (ppf) Grade Range Type Collapse Collapse Burst Burst 9-5/8" 40 L-80 3 BTC 3,090 psi NA 5,750 psi 4,888 psi 7" 26 J-55 3 BTCM 4,320 psi 3,672 psi 4,980 psi 4,233 psi 31/2"* 9.3 L-80 2 SLHT 10,530 psi 8,951 psi 10,160 psi 8,636 psi *ifneeded Fluids to be disposed of in the annulus will be limited to drilling wastes associated with drilling a well as defined in 20 AAC 25.080 (h).

The Drilling Engineer will forward the information to the Agencies. RECEIVED NOV 2. 8 2000 Alaska 0JJ & Gas Cons. Commission Anchorage I 8/4/00, v2 Silvertip PRESSURE ANALYSIS AND PREDICTION (Per 20 ACC 25.005 (c) (9); 20 ACC 25.033 (f); and 20 ACC 25.061 (a)) DISCUSSION: An analysis and prediction of overpressured strata was performed for the Silvertip well as required by AOGCC regulations. Phillips does not expect to encounter abnormal pressure from any zones. The prediction is based on an evaluation of offset wells West Sak #5, KRU State #2, Rock Flour #1 and two of the West Sak Pilot wells #14 & #13. Attached are the following: · Mud weight versus depth graph for these wells. · Seismic analysis for Silvertip. Pore pressure, frac pressure and anticipated mud weight graph. · See attached comments regarding the seismic data interpretations. · As required by Phillips internal SOP's, a pre spud meeting will be held prior to spudding the Silvertip well to discuss all potential drilling hazards.

Gommissio~ A~chora~e Subject: Pre-Drill Seismic Pore Pressure Prediction for Silvertip 1 Date: November 22, 2000 Summary Seismic velocity data was used to predict pore pressures likely to be encountered in the proposed Silvertip 1 well location. A local compaction trend and a local velocity to pressure gradient translation trend model were established using control from the W Sak 5 well. 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, Abnormal pressures which may indicate shallow hazards were observed on the 3D data outside the immediate area of the proposed Silvertip well borepath. Seismic Processinq The accuracy of seismic geopressure analysis depends critically on the accuracy of the input velocity field. The velocities used for pressure prediction were generated using Phillips' AVEL 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 W Sak 5 offset well was used to establish both a local normal compaction trend line and local velocity vs. pressure translation trend model. This model was compared to models calculated for other area wells (W Sak Pit lS, W Sak Pit 10, Rock Flour 1, KUP 34-11-10_1, KRU State 2) and found to be a good match. Procedure 1 .) A Normal Compaction Trend Line (NCTL) was determined for a series of seismic lines from the KRU3D seismic dataset. The slope of the individual seismic NCTLs matched the slope calculated at the W Sak 5, but the intercepts varied slightly from the W Sak 5 NCTL. This is not unexpected as the seismic velocity measures a larger component of horizontal velocity vs the well sonic Icg which measures primarily vertical velocity. The regional well NCTL has a slope of 181; the seismic lines have an average slope of 196. The slope of the NCTL line is-4.9e-5. 2.) The difference between interval transit times (ITT), recorded by wireline sonic logs (AT) in the existing wells or by seismic 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,/tAT. 3.) A translation trend model was established by comparing transit time differences (/tAT) to mud weights. This model calculates pressure gradients (PP) using the equation PP = C2*AAT**2 + C1 */tAT + C0 Where C2: 8.01e-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 (from a West Cameron model). W Sak 5 Figure #1 is the pore pressure gradient calculation for the W Sak 5 well. The left side is the wireline sonic DT (black curve) with the NCTL (red line). The right side is the pore pressure gradient calculation (blue curve), actual mud weight (green curve), and the calculated fracture gradient (red curve). Casing points, formation tops, and lithology changes are as labeled. RECEIVED NOV 28 2000 Alaska Oil & Gas Cons.

Although the observed anomalies do not intersect the proposed Silvertip borepath, there is an anomaly that comes within close proximity of the borehole between 3000 and 3200 ft. Figure 14 and Figure 15 display the observed anomaly at closest proximity to the Silvertip borepath at 3017 ft in depth. The distance to the anomaly located at CDP 1254- 1262 is approximately 990 ft. Predicted Pore Pressure Gradient Displays (depth & time) Figure # Seismic Line Silvertip Well Depth 14 IL 1322 3017 ft 15 IL 1322 3017 ft Depth Time It is probable that the observed anomalies are not associated with zones of high pressure. When viewed in 3D, the apparent pressure anomalies appear to be associated stratigraphically with the Ugnu sands and may represent a decrease in impedance due to the presence of sands. Analysis of Icg data from the W Sak Pit 10 well indicates the presence of thin beds of coal in the Ugnu interval and the possible presence of thin beds of gas-charged sands, either of which could potentially cause a slow-down in seismic velocity and result in a false pressure anomaly. QC of the prestack seismic data shows that the seismic velocity picks in the zone between K-15 and the W Sak sands are ambiguous in some of the locations which show a high pressure response.. Due to the Iow effective fold of the 3D data these ambiguities can not be resolved. There are indications that the seismic velocities might be faster than picked, which could lead to an abnormally high pressure response.

Commission Anchorage Conclusions 1 .) There are no apparent shallow hazards at the proposed Silvertip well surface location or in the intersecting the proposed borehole path. 2.) Potential shallow hazards are observed in the general vicinity of the well location, but do not intersect the proposed borepath. Due to the Iow effective fold of the 3D data these anomalies could not be fully evaluated. If there is a need to better understand these anomalies, shallow velocity trends from regional 2D seismic lines should be incorporated into the model, in addition to re-running AVEL on the 3D seismic volume after carefully re-picking shallow velocities.

The well is designed to penetrate and further develop the production potential of the Kuparuk sands in the vicinity of 1J Pad. In the event the Kuparuk interval is not sufficient to complete, the possibility exists that the wellbore would be evaluated as a potential West Sak producer. The well is designed as a conventional producer and is planned for a 9-5/8" surface casing string, a 7" intermediate string set in the HRZ above the Kuparuk interval, and a 3-1/2" production liner set thru the Kuparuk sands. The well will be drilled and completed using Nabors 14E. Completion plans call for running a 3-1/2" gas lift production tubing string. Attached is the information required by 20 ACC 25.005 (c) for your review. There are no shallow hazards expected at Silvertip (see attached graphs). The nearest offset wells indicate no overpressured intervals or lost circulation zones. There will be no reserve pit for this well. Waste drilling mud will be hauled to a KRU Class II disposal well. If a production casing string is set in this well Phillips requests that the Silvertip well be permitted for annular disposal of fluids occurring as a result of drilling operations, per regulation 20 AAC 25.080. As in the past Phillips would submit a 10-403 Form to the Commission with the appropriate t~chnical information. All cuttings generated will be either stored temporarily on site or hauled to the Prudhoe Bay Field for temporary storage and eventual processing for injection down an approved disposal well. If this well is tested, the produced fluids will either be hauled to Kuparuk for recycling or injection into an appropriate disposal well or the produced fluids will be reinjected into the Silvertip wellbore. PHILLIPS Alaska, Inc. Subsidiary of PHILLIPS PETROLEUM COMPANY Please note that Phillips does not anticipate the presence of H2S in the formations to be encountered in this well. However, there will be H2S monitoring equipment operating, as is the usual case while drilling wells in and near the Kuparuk River Field. If you have any questions or require any further information, please contact me at 263-4603 or Tom Brassfield at 265-6377.
