While performing the first step of this proposed work (a step -rate injectivity test) BP found that the OA shoe did not have sufficient injectivity to allow cement placement. Therefore, BP requests the cancellation of Sundry #318-526. We intend to return the well to Operable status and perform annual subsidence drifts to monitor for any tubing restrictions through subsidence zones. Please let me know if you have any questions or require additional information.

P.O. Box 196612 Anchorage, AK 99519-6612 Subject: Application for Extension of Pilot Production Operations Well W-200; and Initial Production Operations at W-201, Prudhoe Bay Unit - Polaris Accumulation (Schrader Bluff Formation), ADL-28263, 047451, and 047452. File: Prudhoe Bay Field - Polaris Pool Dear Mr. Beuhler: The AOGCC has received an application from BP Exploration (Alaska) Inc. ("BP") to extend pilot production operations at the Polaris prospect, Prudhoe Bay Unit, at Well W-200 through August 31,2001 and to initiate pilot production operations at Well W-201. The request is based on the need for additional information to evaluate primary development and establish a depletion plan. On February 22, 2001, BP provided additional information to Jack Hartz, AOGCC Sr. Reservoir Engineer, regarding primary production and the anticipated pressure response during the extended production period. The AOGCC approved the original request for a waiver of the GOR limitations of 20 AAC 25.240 for production operations on W-200. The waiver of the GOR limitations is necessary to continUe tract and production operations at W-200, and the initial tract and production operations at W-201. Prior production reporting and allocation procedures are still applicable. Production should be reported to the Polaris Undefined Pool, number 640160. Your commitment to gather pressure data and maintain reservoir pressure above bubble point will ensure reservoir energy is not diminished unnecessarily. We anticipate you will keep the Commission informed about any significant developments. Therefore the Commission approves an extension of the Gas-Oil ratio variance through the end of AugUst 2001 for well W-200 and through February 28, 2002 for W-201, conditioned on reservoir pressure performance. AOGCC approval is coincident with any restrictions imposed by The Division of Oil & Gas on Tract or PA operations. Pressure data should be forwarded to the AOGCC after each survey or pressure test. If there are any questions please contact Jack Hartz at 279-1433 ext. 232. Sincerely, Cammy'Ta~r, Chair Copy: Mark Myers, DOG D.E.

Sample composition is presented in Table 1, and details of a constant composition expansion in Table 2. At the reservoir temperature of 99°F the fluid had a saturation pressure of 1690 psia. Fluid density at reservoir pressure of 2275 psia was determined to be .8602 g/cc. Viscosity measurements are presented in Table 3 and plotted in Figure 1. The viscosity at 2287 psia was measured to be 14.22 cP. Results from a three-stage separator study are summarized in Table 4, with gas and liquid compositional information presented in Tables 5 and 6. The total G©R was measured to be 286.7 SCF/STB, for a Formation Volume Factor of 1.111 and an APl of the spent oil of 22.2. A seven-stage differential liberation study was also undertaken. Oil properties from the study are summarized in Table 7 and gas properties in Table 8. Gas phase compositions are presented in Table 9 and the composition of the'residual liquid in Table 10. Relative Volume vs. Pressure is plotted in Figure 2 and Solution GOR in Figure 3.

PLUGS DEAN STARK FLUID SAT. -VERT, PLUGS PARTICLE-SIZE DISTRIBUTION RESULTS 7 INTRODUCTION Core Laboratories was selected by BP Exploration (Alaska) Incorporated to perform analysis upon cores recovered from the Schrader Bluff Field, Alaska. The conventional core material was taken using aluminum inner barrel methods and was handled in the field by Core Laboratories personnel. Initial processing of the core was performed in the field followed by additional processing at Core Laboratories in Anchorage. Two-foot long slabbed "bulk" core segments were shipped frozen to Bakersfield California for sampling. The routine samples were sleeved, Dean Stark extracted and soxhlet cleaned in Bakersfield prior to shipment to Core Laboratories in New Orleans for porosity and permeability measurements utilizing the CMS automated core measuring system. In addition to performing the initial steps of the routine analysis, fluid extraction for tracer analysis, resistivity and APl oil gravity determinations as well as particle-size distribution determinations were performed by the Bakersfield Laboratory. Samples taken for additional testing were forwarded frozen to TerraTek. This report is divided into seven sections. Section one contains a description of services. The second section presents tabulated results of the CMS measurements made upon the horizontally oriented one-inch diameter samples. Section three contains a presentation of the hydraulic flow unit classification determined for each horizontal sample with the results sorted by sample depth. Section four presents the hydraulic flow unit classifications sorted by hydraulic unit class. Section five presents the results of CMS measurements made upon one and one-half inch diameter vertically oriented samples. Section six presents the results of the Dean Stark fluid saturation analysis performed upon the vertically oriented samples. And the final section presents the results of particle-size distribution determinations performed upon selected samples. A plot summarizing the analysis results may be found at the rear of the report. In conjunction with the report, the core analysis results are supplied in Excel format on an IBM PC compatible floppy diskette. CONVENTIONAL CORE Well-site Core Handlin.q Core Laboratories personnel under the direct supervision of BP's representatives performed all well site core handling. The following is a generalized summary of the field handling. Two two-foot segments and two one-foot segments were taken from each six feet of recovered core. A continuous two-foot segment was taken at the top of each interval, sealed, and frozen. Next a one-foot segment was taken for preservation using BP's soft sediment system followed by a second continuous two-foot segment. The final foot of each six-foot segment was wrapped with Saran and foil and then wax dipped for preservation. Numerous other chips and samples were also taken in the field for a variety of tests. The prepared core material was later transported to the Anchorage lab for further processing. Core Processing - Anchorage Upon arrival in Anchorage, the one-foot segments were taken to a local hospital for x-ray CT scanning. The one-foot segments were returned to its proper place as each .core was "reconstructed" and scanned for natural gamma activity from the bottom up. The gamma scans were over-nighted to Bakersfield for digitizing and hard copies as well as data diskettes were returned to Anchorage upon completion of the digitizing. The frozen two-foot core segments were extracted from the aluminum sleeves oriented and installed in plastic tubes. Annular space between the tube and the core was filled with gypsum (plaster of Paris) to support the core during slabbing and sampling. One the gypsum had set; the segments were again packed with dry ice to ensure complete freezing prior to further handling. Slabbing of the stabilized core segments was performed using a one-quarter / three-quarter cut so as to expose the maximum dip of the bedding. The two slab sections were taped back together with a Saran-wrapped plywood plank between them and returned to frozen storage until such time as a sedimentologist could describe the one-quarter "museum" slices. After description, the cores were photographed under white and ultra-violet lighting on a foot by foot basis. Upon the completion of photography, the planks were replaced on the "bulk" segments wrapped with Saran, taped into place, and returned to frozen storage. The bulk two-foot segments were subsequently packed in insulated crates with dry ice and shipped frozen to the Bakersfield Laboratory.. The one-quarter sections were kept in Anchorage and were mounted in casting resin for permanent preservation and display. Core Processinq - Bakersfield The crated core material was met at Los Angeles airport by Core Laboratories personnel and transported to our Bakersfield, Californi. a facility. Ample dry ice was on hand when the core was met in Los Angeles to re-stock the crates and maintain the frozen condition of the core. Upon its arrival in Bakersfield, the core was maintained in its frozen state until sampling and analytical procedures were finalized. One-inch diameter plugs for permeability and porosity determinations were drilled as near as possible to the ends of each two-foot segment, as well as in the center as per BP's instructions. Efforts were made to ensure that these plugs were taken parallel to bedding, however, the ice and frost that resulted from the requirement to keep all of the material at dry-ice temperatures throughout sampling necessitated drilling most of the samples "blind~. End trims from both sides of each plug were packaged in zip-lock sample bags, the trim from the slab face was designated for particle-size distribution determinations with the end nearest the exterior of the core set aside "just-in-case~. Vertically oriented one and one half inch diameter plugs were taken at six-foot intervals for Dean-Stark analysis, and additional horizontal samples were taken for sedimentological studies at specific points requested by the sedimentologist. Diamond core bits lubricated with liquid nitrogen were used to drill all sample plugs. As per BP's instructions, segments of Saran-wrapped pipe insulation were placed into each of the holes left by the sampling. Prior to replacing the plywood planks and re- wrapping the sampled segment with Saran, digital images were taken to document sample location as well as to document the suitability or unsuitability of additional sampling if required. After re-packaging, the segments were again packed into the insulated crates and maintained in a hard-frozen state with dry ice. Subsequent to the "routine" sampling and re-sealing of the segments, a list of special core analysis sample depths was received. Keeping the material frozen at all times, the selected segments were again taken from the insulated crates, Saran and plywood were removed, and one and one-half inch diameter plugs were drilled using liquid nitrogen as the lubricant, for frozen shipment to TerraTek. Following this second round of sampling, additional digital images were taken of the affected segments and each was once again planked, wrapped, and repacked with dry ice in the insulated crates. Sample Preparation- Drilled Plu.q$ After the ends had been trimmed and squared, the ddlled plugs were wrapped with Saran and foil labeled and placed on dry ice until the three samples from the segment had been taken. Each group of three to four plugs was then taken to the "buttoning" area where the frozen samples were wrapped with Teflon tape, inserted into tin sleeves and fitted with 120 mesh end screens. Each sample was loaded into a hydrostatic core holder and a seating pressure of 200 psi was applied to set the sleeving materials to the still-frozen samples. After one minute at 200 psi, the samples were removed from the holder' and allowed to thaw in sealed in zip-lock bags. Once thawed, the plugs were reinstalled in the hydrostatic holder and a pressure of 500psi was applied to further seat the sleeving materials. The same procedures were used for both the one-inch diameter and one and one-half inch diameter samples. Fluid Extraction - One-inch Diameter Sample,,, The sleeved samples were weighed and placed into soxhlet extractors for batch cleaning with six to nine samples comprising a batch. Water and the contained oil were removed from the samples by alternating toluene and methanol as the solvents with periodic refreshing of the solvents until no discoloration of the toluene could be detected, and when complete removal of chloride-salts was verified by the failure of a silver chloride precipitate to form when silver nitrate was added to the methanol effluent. For solvent removal, the samples were dried in a convection oven at 105°C until constant weights were attained. Upon weight stabilization, the plugs were cooled to laboratory temperature in a desiccator and carefully packaged for shipment to Core Laboratories in New Orleans for porosity and permeability determinations. Fluid Extraction - One and one-half Inch Diameter Sample,- Each sleeved sample was weighed and placed into an individual Dean Stark extraction unit. The boiling flasks were filled with de-watered toluene and all water was removed from the samples by Dean Stark (solvent distillation.) techniques. Extraction was performed for a minimum of sixteen hours after which the volumes of the water trapped in the collection tubes were closely monitored and extraction was continued until constant water readings were obtained. The collected water was drawn from the tubes using tared syringes and the volume calculated by mass balance. Following the Dean Stark extraction, the plugs were transferred to soxhlet extractors for batch cleaning with two samples comprising a batch and following the cleaning procedures as described for the one-inch samples. For solvent removal, as before, the samples were dried in a convection oven at 105°C until constant weights were attained. Upon weight stabilization, the plugs were cooled to laboratory temperature in a desiccator and carefully packaged for shipment to Core Laboratories in New Orleans for porosity and permeability determinations. Grain Density Determinations Grain porosimeters. volumes were determined using Boyle's Law small volume helium Metal jacket, Teflon tape and end-screen weight and volume corrections were applied to the jacketed samples. The grain density of each plug was calculated using Equation 1. Sma = r'g Where: Sma = Matrix (grain) density (g/cc) Mg = Grain mass (g) Vg = Grain volume (cc) CMS-300 Following grain volume determinations, the plug samples were packaged and shipped to Core Laboratories in New Orleans for porosity and permeability determinations using the CMS-300 automated core measurement system. The CMS- 300 is capable of applying higher confining (overburden) pressures than are possible with the standard lab equipment All of the samples were run using a confining pressure of 1500 psi. Porosity Determination The CMS-300 makes direct pore volume measurements upon the samples at overburden stress utilizing Boyle's Law double-cell methods. Porosity values were calculated using Equation 2. I (V~ VP )1'100 (2) * = Where: ~ = Porosity (%) Vp = Vg : Pore volume (cc) Grain volume (cc) CMS Permeability The CMS-300 utilizes unsteady-state methods to determine permeability. The pressure differential across the sample plugs is monitored by computer as the upstream pressure decays which allows the calculation of a permeability value corrected for gas-slippage. In addition to the gas-slippage corrected or Klinkenberg permeability, the computer calculates standard permeability to air values. Hydraulic Unit Analysis The results of the CMS-300 porosity and permeability measurements performed on the one-inch diameter samples were used to generate hydraulic unit classifications. Reservoir quality index (average pore throat size) and pore ratio values were calculated for each sample using Equations 3 and 4. RQI = 0.0314 o~/..~a (3) PR = (4) Where: RQI = Ka = PR = Reservoir quality index Permeability to air (md) Fractional porosity Pore ratio RQI and PR values were used to group the data into hydraulic units. Each hydraulic unit represents a unique pore geometry relationship and provides the foundation for the integration of core and electric log data. The results are presented in two tabulated formats, sorted by sample depth and sorted by hydraulic unit. Fluid Saturation Determinations The pore volume results from the CMS-300 analysis and the fluid extraction results from the Dean-Stark analysis on the one and one-half inch diameter samples were utilized to calculate oil and water saturations. Equations 5 and 6 were used for the fluid saturation calculations. c~° ~ '100 (5) (6) Where: So = Sw = Mf = Md = MW = Vw = Vp Oil saturation (%) Water saturation (%) Fresh sample mass (g) Extracted and dried sample mass (g) Extracted water mass (g) Extracted water volume (cc) Density of oil Pore volume (cc) Laser Particle-Size Analysis End trims from each sample designated for particle-size distribution determination were utilized for the analysis. Water was removed from the material using toluene in a Dean-Stark apparatus. Any hydrocarbons not removed by the Dean-Stark process were extracted by soxhlet with methylene chloride as the solvent. The cleaned samples were 0 dried in a convection oven at 230 F to remove the solvents. Each of the dried samples was disaggregated using a mortar and Teflon-tipped pestle. The disaggregated sample material was passed through a series of five screens graduated at 0.5 phi intervals to determine the quantity and size distribution of any material greater than 20 mesh (.033"). The portion of sample remaining on each of the screens was weighed to the nearest hundredth of a gram and the weight was recorded. A Coulter LS-130 particle-size analyzer was used to determine the siZe distribution of the material passing the 20-mesh sieve by laser diffraction techniques (modified ASTM D-4464). The pre-sieved sample material was dispersed in a liquid medium and rePeatedly passed through the analyzer's laser beam. An array of detectors recorded the resultant dispersion patterns, which were then analyzed by computer. Results of the laser analysis were combined with the sieve data to encompass the entire size-range and are presented in tabular and graphic forms. Sample Disposition Ali sample plugs were returned to Core Laboratories Bakersfield from Core Laboratories- New Orleans and are currently stored in California. The two/thirds "bulk" sections of core are being maintained frozen at an off-site cold storage facility pending instructions for further analysis or permanent storage arrangements. BP Expi.

Dear Chairman Christenson: As you are aware, BP as PBU WOA Operator on behalf of the lease owners, has drilled two Schrader test wells in the PBU WOA and requested approval of a Pilot Production Plan. S-200 (aka.SB-01) bottomed on T12N-R12E UM Sec. 27 within ARCO/Exxon lease ADL 28258. W- 200 (aka SB-02) bottomed on Sec. T11N-R12E Sec. 21 within Mobil/Phillips/Chevron lease ADL 28263. Both wells have been briefly tested from various Schrader Bluff formation intervals, but additional appraisal completion or testing work remains to be performed before the pilot period. Both wells will be Completed in the Schrader Bluff formation, no approval is requested for downhole commingling With formations other than the Schrader Bluff. The wellwork is expected to be performed in September and October 1999. Production testing is not expected to exceed seven days per well. Consistent with existing practices, BP requests approval by the AOGCC on behalf of ARCO/Exxon and Mobil/Phillips/Chevron to commingle production with other pools for processing at PBU Gathering Center 2 during the testing period. Production allocation will be based on the existing well test methodology approved by the AOGCC, based on well tests conducted at S and W pads. Similar approval was granted by letter of 12/18/97. BP× will undertake to advise the Division of the status of well operations in a timely manner. If you have any questions, please contact Steve Deckert at (907) 564-4128.

Numerous attempts have been made to retrieve the fish with no success. Current plans are to temporarily suspend the well by ch'culating the well to kill weight fluid, installing one joint of tubing below the tubing hanger, installing a TWCV, ND BOP, NU and test tree and set a BPV. Nabors rig 18E will then move off of the well for 2 weeks of rig maintenance. During rig maintenance operations, wireline and coiled tubing operations will continue to attempt to retrieve the fish. At the end of rig maintenance, 1SE will move back onto the well to perform one of the following operations: 1) In the event the fish is retrieved, set a liner (op packer and test same. Run tubing completion. ND BOPE, NU Tree and test, Freeze protect and RDMO, 2) Dump bail cement on top of fish. Chemical cut below the liner hanger at 4058 and retrieve. Retrieve the overshot packoff. Wash over the 3-1/2" liner to a point below 4534' and outside cut liner and retrieve. Run new tie back liner with paekoff overshot. Run tubing completion. ND BOPE, NU Tree and test, Freeze protect and RDMO. OR 3) Chemical cut below the liner hanger at 4058' and retrieve. Retrieve the overshot packoff. Set combination abandonment/kickoff plug. Redrill 6" wellbore to ~6200'. Run and cement 4-1/2" liner. Run 3-1/2" tubing completion. ND BOPE, NU Tree and test. Freeze protect and RDMO. The purpose of this notification is to advise of this planned temporary suspension. Upon internal and partner evaluation and approval of the proposed options, the appropriate Sundry notice and/or Application for Permit will be submitted, if necessary. It is anticipated the proposed temporary suspension will commence immediately. If you concur, please initial and return via fax at 564-5193.

The well was perforated from 5176' - 5178' and from 5290' - 5294' and frac stimulated. During the frac job, the liner parted at approximately 4091.' resulting in a large volume of frac sand fill up above the perfs. Since that time several attempts have been made to run sinker bars into the liner below the part with no success. The well is currently dead, due to the significant volume of sand above the perfs. This workover will pull the existing completion, mill the liner to within 10' of the top of the good cement (per attached CBL), run a new liner top tie back assembly and cement same. A similar tubing completion will be run. All cleanout and completion/recompletion will be done by the PE's following rig release.

Denis PBU New Business Development BP Exploration (Alaska) Inc. P.O. Box 196612 Anchorage, AK 99519-6612 , Subject: PBU Schrader Bluff Undefined SB #1 rface Commingling of Test Production Dear Mr. Denis: The Commission received vour letter dated December 5, 1997. requesting permission to commingle undefined pool production from the Schrader Bluff formation during test operations of the SB #1 and SB #2 wells. Your request is for surface commingling only and that there will be no downhole commingling of formation fluids from the formations comprising the Prudhoe Pool. Production from SB # 1 and SB #2 should be reported separately to the Schrader Bluff Undefined Pool, pool number 640160, for those months the wells are tested. Attached is a summary of the standard allocation procedures for commingling fluids from different pools. These procedures have been developed over the last several years and can serve as a guideline for allocating the fluids from the 'test operations. Disregard paragraph (c) until such time the wells are placed on regular production. At least two tests per month are required during those months the wells are produced. We look forward to hearing results of the test. If there any questions regarding commingling or reporting procedures, contact Jack Hartz at 279-1433 ext. 232. Chairman Attachment Cop3': K. Boyd. DNIL/DOG J. Pilkington. DOR PbuSBco.doc Surface Commingling and Common Facilities ao Production from the Schrader Bluff Undefined oil pool may be commingled on the surface with production from other pools for processing at PBU GC facilities prior to custody transfer. bo Production from each well will be determined by the following well test allocation methodology. Allocation data and well test data will be supplied to the Commission monthly in both computer file and report formats. i. Conduct well tests to determine production rates for each well. ii. Calculate each well's theoretical monthly production (TM?) based on well test rate(s) and actual time on production. iii. Sum the TMP volume for all wells in all pools. iv. Determine an allocation factor as the ratio of the metered volume to the TMP for all wells i.n all pools (i.e., metered/TMP) v. Calculate each well's actual monthly production (AMP) volume as: AMP = TIVI~ x Allocation Factor Co NGL's will be allocated to each pool based on actual gas production volumes and NGL process simulations. Process simulations will be updated at least once per year based on NGL samples and results reported to the Commission. de Each producing well will be tested at least twice each month. Wells that have been shut in and cannot meet the twice-monthly test frequency must be tested within five days of startup. All available test separator capacity within the constraints imposed by operating conditions must be utilized for well testing. e. Optimum test duration and stabilization time will be determined on a well by well basis by the operator. Water volumes will be determined by API/MPMS approved methods, or the use of industry proven on-line water cut measurement devices approved by the Commission. g. API gravity will be determined for each producing well annually by an API/MPMS approved method. h. Gas samples will be taken and analyzed for composition fi.om each non gas lifted producing well yearly.

Commi { J Thank you for the ,othpportunity to discuss the leak off test issues on well SB-02 which occurred on the 30t November this year on Nabors Rig 18e. The intent of this letter is to document and clarify the events surrounding the leak-off tests and develop actions to satisfy your concerns. Attachment 'A' clarifies the associated events. Our understanding of the salient points and concerns following discussion of the incident in your offices on Thursday the 4th December were: · The primary concern of the AOGCC regarding adherence to our Leak-off Test procedures was resolved when you were provided with information and data that showed that SSD had rerun the leak-off test as described in our procedures after an unacceptable initial test result was obtained. Prior to our meeting today, you were unaware that we had rerun the test twice before drilling ahead a short distance to rerun the test yet again. , The post pumping shut in period of leak-off tests 'A' and 'B' was less than 10 minutes in duration.. This was SSD's decision after concluding that the leak-off tests had established evidence of an anomaly requiring further investigation. In future we will hold tests for the full 10 minute shut in period to establish pressure data points as stated in our LOT Standard Procedure. 3. SSD did not provide adequate information on the leak-off test results to the AOGCC Senior Petroleum Engineer. 4. Well integrity was not compromised at any point during, and subsequent to, the leak- off test operations. 5. It was safe and prudent to continue drilling operations on the well. 6. The well was.not, and is not intended to be, a candidate for annular injection. 7. Appropriate efforts were made for the North Slope inspector's endorsement of the drilling program change following the aborted leak off tests. 8. Ready agency telephone contact of senior SSD staff is difficult. AOGC, C, Leak-Off Procedures December5, 1997 To assure full compliance with our procedural requirements we will direct our staff to follow the SSD leak-off test procedures in aborted and suspended leak-off test operations as appropriate. This will enable us to gain further operational data points and aid in leak-off test data analysis. In those wells where there is the potential for concern in relation to leakoff test results and other operational integrity data we will ensure that the AOGCC Senior Petroleum Engineer is advised and provided with adequate information to enable a balanced assessment of operational integrity as a matter of priority. Office networking and operational demands have resulted in the promotion of the paging system to the primary means of contact for all senior drilling staff. SSD will provide the AOGCC with an updated list of contact pager numbers and telephone numbers for senior staff on a regular basis. I trust the foregoing resolves the AOGCC's concerns about this matter. Thank you for meeting with us today. Yours sincerely, David Nims PBU Drilling Superintendent Shared Services Drilling N18e Well SB-02 9.5/8" Csg LOT (11/29/97) Background Operations Prior to LOT The 9.5/8" casing was set and cemented at 3113ft using a two stage cementer set at 2202ft. There was full returns on the first stage and a small amount of cement was recorded on bottoms up after bumping the 1 st stage plug, The stage cementer was sheared open and the well was circulated to allow time for the first stage cement to thicken. The second stage cement was pumped with returns to surface, the plug bumped and the stage cementer closed with 1900 psi again with full returns to surface. The casing string was reciprocated until approximately half of the first stage lead cement circulated had passed the casing shoe, tight hole then required the casing to be landed on its hanger. The stage collar was drilled out and the well circulated clean at the landing collar, 3028ft. Following a poor pressure build up on the initial test consistent with aerated mud, the well was given a full circulation of defoamer treated mud after which a 3500psi casing integrity test was achieved. Leak Off Test Events After drilling out the shoetrack and 25ft of new hole to 3145ft, the well was circulated clean in preparation for the LOT. At 2130hrs on 11/29/97, Test 'A' was taken to 850 psi and suspended before leak off due to divergent build up characteristics from the casing test. The well was circulated surface to surface with defoamer before a repeat test to remove any possible air entrainment. This was not considered a viable test. Test 'B' was taken to 1030 psi before it rapidly broke down, bleeding off to 340 psi within six minutes, there were no visible surface leaks. This was not considered a viable test. - The well was slowly pressured up "(Test 'C')" and started to pump away at 600Psi, the pump was shutdown and the pressure rapidly bled off to 350psi where it was held for four minutes before it was manually bled off. This was not considered a viable test. Notification Process and Follow Up The Company Rep communicated the problem to the Drilling Superintendent (D.Nims) in accordance with the procedure. He was advised that all three test were invalid. D. Nims suspected that the cement rathole had not been fully drilled leading to the artificially high pressure and breakdown seen in Test B and requested that the drillpipe tally be rechecked to confirm the depth of the rathole. It was known at this point that well would not be used for annulus injection. To avoid any possibility of pipe tally error and ensure that a representative casing shoe strength test was achieved to safely drill ahead the Company Rep was requested to drill 200ft, circulate and repeat the test after contacting the North Slope AOGCC inspector (John Spaulding). The AOGCC inspector was paged at 2330hrs to inform him of the situation and endorse the program change. After one hour of waiting the inspector had not called back and the decision was taken to drill the 200ft. The well was circulated with clean mud and leakoff test 'D' successfully achieved a representative leakoff EMW of 12.39 ppg associated with a leakoff pressure of 450psi by 0300hrs on 11/30/97. The LOT was conducted in accordance with SSD procedure and the rig drilled ahead to 3600 ft by 0600hrs. The AOGCC inspector called the rig at approx 0530 hrs that morning and stated he had not responded because he had been at the Badami location. The LOT events were relayed to the inspector who commented that "he liked the approach of drilling the 200ft and repeating the test". He also requested a fax of the LOT results. Copies of inviolate test 'B' and the representative test 'D' were sent immediately to him and Blair Wondzell at the AOGCC offices in Anchorage. The AOGCC inspector was paged to confirm receipt and understanding of the fax and program endorsement. He called the Company Rep and both tests were discussed in detail. He was then specifically asked to confirm his agreement to continue drilling ahead and replied affirmatively. AOGCC Concerns The 'permit to drill' signifies that SSD intends to follow FIT's in accordance with SSD written procedures. Surface equipment should have been checked for leaks and the LOT redone. The Tests and notification procedures were carried out in accordance with SSD procedures. There were no visible leaks on the surface equipment to account for the sudden pressure drop offs in LOT attempts 'A' 'B' and the pumpoff test 'C'. The Company Reps attempts at a LOT were not successful and he followed procedure in calling the Drilling Superintendent The 'LOT' was attempted three times (Tests 'A' 'B' and 'C'), after drilling twenty five feet of new hole below the 9.5/8" casing. Tests 'A' and 'B' were indicative of a cement sheath breakdown later confirmed by the pumpoff in test 'C'. None of these test were considered viable LOT tests by the Drilling Superintendent. To ensure that a representative LOT was achieved and obviate any possibility of a pipe tally error it was proposed to drill two hundred feet and repeat the test. (The 350 psi minimum static pressure attained during pumpoff test 'C' indicated a 55bbl kick tolerance, more than enough for the volume associated with proposed two hundred feet to be drilled). The Company rep was specifically told to ensure that the N.Slope AOGCC inspector was appraised of the situation and the forward plan. Good efforts were made to contact the AOGCC inspector who was not contactable. Only after waiting an hour for the inspector to reply to his page was the decision made to drill the two hundred feet and re- attempt the LOT. The N.Slope AOGCC inspector agreed with the procedures that had been carried out and gave no indication of anything untoward and specifically commented that he liked the approach of drilling the two hundred feet and repeating the LOT.

SB #1 will be bottomed on T12N-R12E UM Sec. 27 within ARCO/Exxon lease ADL 28258, SB #2 will be bottomed on Sec. T11N- R12E Sec. 21 within Mobil/Phillips/Chevron lease ADL 28263. Both wells will be tested from the Schrader Bluff formation, no approval is requested for downhole commingling with formations other than the Schrader Bluff. The wells are expected to be ready for test production in December 1997 (SB-02) and January 1998 (SB-0~). Consistent with existing practices, BP requests approval by the AOGCC on behalf of ARCO/Exxon and Mobil/Phillips/Chevron to commingle production with other pools for processing at PBU Gathering Center 2 during the testing period. Production allocation will be based on the existing well test methodology approved by the AOGCC, based on well tests conducted at S and W pads.

The pressure bled off quickly to about 550 psi and then started to decrease with time, after 6 minutes the pressure was approx. 350 psi. At this point the test was discontinued. See the attached graph for "1st Leak off test". I understand that the rig Foreman called SSD in Anchorage and discussed the situation. As a result of that meeting, another FIT was conducted after drilling 200' (to 3345' md). The second test broke over at approx. 650 psi; after 14 minutes it was pretty well "lined out" (successive pressures horizontal) at approx. 280 psi. See the attached graph for the "2"d Leakoff test". Note: These tests are difficult to read because the graph is marked in 100 psi. increments - 550 psi./in. Problems: 1. The first test exhibited a breakdown, which was probably the opening-up of a cement channel. The second test nearly confirms a cement channel. The two tests together fit the classic definition of FITs defining a cement channel. 2. The fall-off time on the first test was only 6 minutes when your procedure requires a minimum of 10 minutes. 3. SSDs written LOT Procedure states "In the event that the pressure continues to bleed off without becoming constant then the surface equipment should be checked for leaks and the test redone." That procedure requires that the "1 st Leakoff Test" should have been redone before drilling ahead. Because the 1 st Leakoff test did not' reflect a well-cemented shoe, it does not meet the criteria for annular disposal. Major Concern: Our concern is not with the safety of drilling to TD in this well, but it is with the SSD personnel not following written procedures when conducting FITs. Commission regulations require a FIT after drilling at least 10' of new formation below a casing shoe (except conductor pipe). Your application for a Permit To Drill signifies that you intend to follow the regulations; frequently a FIT is specified in your application. When signing the PTD, the Commission believes that you will conduct the required FITs in accordance with your written procedure. If the rigs continue to ignore your published FIT (LOT) procedures and continue to drill ahead when there is evidence of a poor shoe job, it will be incumbent on the Commission that we impose uniform standards and dictate interpretation criteria. This would be better done thru AOGA. I suggest we get together and talk about this. Please call me at 279-1433 ext 226.
