Well names currently include a forward slash "I"followed by an obsolete bottom hole location designator. HAK would like to retain the well number as well as the "A, B, C...." sidetrack designations but remove the "/suffix". For example, "DUCK IS UNIT SDI 1-09A/121" would become "DUCK IS UNIT SDI 1-09A". The attached spreadsheet includes original and new names for all Duck Island wells. While performing the review of Duck Island well names, HAK found a single well, "DUCK IS UNIT SDI 4-20/M35" (PTD# 1861730), that should also be modified to include an "A" label to reflect the fact that the well is a sidetrack from the original "DUCK IS UNIT SDI 4-20/T34" (PTD # 1861500). The original wellbore, abandoned 10/13/1986, was sidetracked to a new bottom hole location completed on 9/9/1987. This well appears to be one of the first sidetracks performed at Endicott. While the bottom hole code was changed, no letter was added to reflect the sidetrack. "DUCK IS UNIT SDI 4-20A" is also included on the attached spreadsheet.

Thc permit to drill docs not exempt you from obtaining additional permits required by lax',' from other governmental agcncics, and docs not authorize conducting drilling operations until all other required permitting determinations arc made. A weekly status rcport is required from thc time the well is spudded until it is suspcndcd or plugged and abandoncd. Thc rcport should bca generalized synopsis of thc week's activities and is exclusively for thc Commission's internal use. Thc nc~v bottom-hole location will require a spacing exception under 20 AAC 25.055. You arc not authorized to open the xvcll to production until after thc commission issues thc spacing cxccption following notice and opportunity for public hcaring. Should an adjacent owncr raise an objection, the commission ma.-,' require BP Exploration to plug and abandon thc well. Blowout prevention equipment (BOPE) must bc tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of thc BOPE test pcrformcd bcforc drilling below the surface casing shoc must be given so that a representative of thc Commission may witness the tcst.

Crandall RE: Request for approval for well 2-56/Eider Drilling Permit Dear Commissioner Johnston, BP Exploration (Alaska) Inc. hereby request for an approval to the above mentioned well for drilling, logging, and casing prior to approval of the spacing exception. This well was originally identified as 2-56/Beluga, but has been renamed at the request of the AOGCC. This well permitted has been submitted, inclusive of a request for a spacing exception pursuant to the requirements of 20 AAC 25.055 due to the location of the reservoir penetration. However, our current projected time to begin operations on this well will occur prior to the 14 day required public notice. This approval will allow BPXA to begin operations without expensive standby drilling operations. We acknowledge the following items with this request: BPXA cannot produce the well prior to approval of the spacing exception. The spacing exception may never be approved.

The closest well is 2-54 which is at 9.84 feet at a depth of 200 feet MD. These wells will be shut in if required as per the Endicott Simultaneous Operations guidelines. FAULTS / PORE PRESSURE / LOST CIRCULATION Production Interval (6"): The Ivishak reservoir pressure should be normal, the Asset estimate of pore pressure (based on nearby SD-08 of 4650 - 4750 psi at 9,575' TVDss) should range from _+ 9.3 to 9.5 ppg EMW. The presense of gas within the Beluga Prospect is uncertain due to the localized and variable nature of contacts. The formation also has the potential for lost circulation due to the faults which define the target Polygon (see Geologic Prognosis for faulting details). Lubricant additions (see above) should be utilized if torque and drag become troublesome, and after extensive testing of mud on location. Flex collars should be utilized in the BHA to minimize potential differential stickinq. Liquid casing and OM seal should be on location to help combat severe lost circulation. NOTE: See the Geologic Prognosis for a detailed description of the expected fault locations and sizes. Review the Pad Data Sheet for trouble highlights throughout MPI history. Well Control: Well control equipment consisting of 5,000 psi W.P. pipe rams, blind rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures.

This is the first well in the Beluga development plan, therefore, results from this well will determine the pace of future development drilling. We will have to drill a new well from surface using the Slim - hole design (10.75" and 7-5/8" casing) and then top setting the reservoir for logging and formation evaluation. A standard 8 valve ultra-slimhole (4.5" x 1.0" for 7." casing) GLM design will be run for the completion on a 4.5" L-80 tubing design with a X/X/XN nipple profile. Directional Plan: The directional plan for the 2-56/BG-01 well consists of nudging in surface, then building with conventional BHA's for the build and hold section at 61°. W Current plans call for up to 2.5°/100' doglegs in this section, but this may be adjusted pending results during the drilling process. After drilling the tangent at 61° degrees, and dropping directionally back into the Sands with 25.94° of inclination, the well will be drilled to +17,045' MD (9,931' TVD). THE DIRECTIONAL TARGET CAN BE INTERSECTED ANYWHERE WITHIN THE TARGET BOUNDRY. THUS UNNECESSARY AND VERY EXPENSIVE SLIDING SHOULD BE AVOIDED TO KEEP THE WELL EXACTLY ON THE WELLPATH. THERE IS NOT ANY GEOSTEERING APPLICATION FOR THIS WELL. Ensure that any and all tolerance lines are not crossed to avoid policy violations. Please coordinate this through both the Operations Drilling Engineer and the Endicott Drilling Superintendent. There are not any known close approaches which require wells be shut in. Any BHA's indicating less than required BUR should immediately be pulled for a more aggressive assembly. Recommended BHA's All motors should NOT be jetted to account for the proposed flowrate and motor performance. Hole conditions and directional objectives should dictate actual flowrates. As mentioned previously, flex collars should be utilized in the 8.5" hole sections to minimize potential differential sticking. We will be using bent housing motors with either 7/8 for a roller cone or 5/6 rotor/stator configurations for PDC bits IF run. Sperry proposed BHA's are attached, however the actual BHA with motor design, MWD/LWD tool configuration, MWD battery life, bit hydraulics will be discussed at the daily wellsite meeting. Directional Survey Program The survey program for 2-56/BG-01 calls for use of Sperry's DWD MWD surveys the entire well. Because of Sperry's standard practice of changing the MWD probes after every bit run, an electronic single shot (ESS) will not be needed, and a gyro is not warranted. Close attention to JORPS is required, with the use of checkshots and survey data validation.

PDC bits will be run in the 8.5" hole section only if Sperry 6-3/4" performance motors are available. Mud Program: The surface hole will be drilled with high vis spud mud, and sweeps as required for hole cleaning. We will use LSND on this well to drill to TD. There should not be any additions of any lubricants in this well without extensive testing of the actual fluid on location. Rheology control can be maintained using Gel and Biozan polymer. At this time raise the LSR YP to the recommended range using Biozan. Biozan sweeps should be pumped to assist in hole cleaning and to prevent the build up of cuttings beds. Mud sweeps are essential for good hole cleaning while drilling. Additions of 3#/BBL each of Baranex and Barotrol should be maintained throughout below 8500 TVDSS. This treatment should result in an HPHT of <14 which is our target. Maintain the pH in the 9- 9.5 range using caustic soda. If torque problems arise, a treatment of 1- 2% Lubetex should be used. If the torque persists, the ERD lubricant mix should be evaluated. The APl filtrate should be reduced to the 4 cc range with PAC and starch. This will reduce the chances of differential sticking and reduce filtration invasion. Tripping Practices / Stuck Pipe / Hole Cleaning Tripping in the 8.5" hole interval should be undertaken with caution due to swabbing possibilities with high viscosity fluids. The bottom hole pressure varies from 2500 psi to 4950 psi (8.6 to 9.5 ppg ). It is recommended that mud weights be maintained in the 10.2 to 10.4 ppg range to control the hydrocarbon intervals, maintain shale stability and minimize the possibility of differential sticking. Faulted intervals may require additions of LCM prior to tripping to insure that the hole remains full at all times. Keep the pipe moving and have an ample supply of lost circulation materials on hand. Baroid recommends utilization of Iow viscosity sweeps to assist with hole cleaning and to minimize the formation of cuttings beds on the Iow side of the hole. No potential hazardous levels of H2S are anticipated in the 2-56/BG-01 well. There have been H2S reading on offset MPI wells of over 1000 ppm. Ensure rig gas detectors are calibrated prior to N/D tree and/or circulating to kill the well. 2-56/BG-01 Drilling Permit Directional Plan #1 1/30/98 _ogging Program: _ogs: 13.5" Hole Curve and Tangent MWD-GR 9.875" Hole Tangent MWD-GR - to 200 feet above HRZ 9.875" Hole Tangent MWD-GR - Res - Den - Neu from 8945 TVDSS to ICP 6" Hole MWD-GR - Res Den Neu to TD 6" Hole Wireline Platform Express Cased Hole: None Sample catchers, mud loggers, and a wellsite Geologist are planned to be used while drilling reservoir. Casing and Cementing This well will require the Slim-hole design with 10-3/4" surface casing and 7-5/8" intermediate casing. These will be cemented as per current recommended practices cementing the surface casing to surface and the intermediate to 1000 feet above the Ivishak. The intermediate casing is being run to facilitate logging and completion of the Ivishak and Lisburne. The reservoir will require a 4.5" 13# L-80 liner to be run across the entire interval. This will be hung off in the 7-5/8" casing at 16,300 feet. Make sure we have 5000 feet of 5" "S" drill pipe to allow for the maximum overpull. Ensure that prior to running liner that the hole is in good condition and that the mud has been conditioned to run casing. Before POH to run liner spot lubricant across the open hole section. If this is considered essential to getting the pipe to bottom ensure that adequate lubricant testing has been performed prior to doing this. Aisc, consideration must be given to a hole opener trip prior to running liner if hole conditions suggest that there may be problems running pipe. This liner will use Hydrill 511 connections to allow rotation at much higher torque and reciprocation than any other connections. Special equipment will be required for this including XO for safety valve and having the liner hanger cut with a 511 connection on bottom. (Do not crossover from buttress as this would be a weak link in the string). The liner should be filled every 5 joints, and circulated prior to going into open hole. Any problem intervals identified while drilling, such as ledges in the Tuffs, will require special care while running casing through. The liner will require 2 straight blade centralizers on every joint to the 200 feet above the top of the Kekituk at _. 14,045, and then one straight blade centralizer on every other joint to the window. If the liner starts to packoff in the open hole, establish circulation and try to wash through. Do not continue to run casing without circulation. If necessary, we will pull casing and make a wiper trip prior to running the liner. The liner running procedure in the detail section should be reviewed. The cementing program is designed place cement 1000 feet above the top of the Kekiktuk formation. The approximate volume will be 150 sacks of Class 'G' with additives as speficied in the casing detail section. Cementing operations at Endicott are continue to be critical with the advancement of both the waterflood and gas fronts. Close attention to detail for this part of the well is critical for the economical success of our drilling program. This reservoir section will require a 4.5" 12.6# L-80 liner. This will be hung off in the 7" liner at 13,730 feet. Make sure we have 5000 feet of 5" "S" drill pipe to allow for the maximum overpull. Ensure that prior to running liner that the hole is in good condition and that the mud has been conditioned to run casing. The liner should be filled every 5 joints, and circulated prior to going into open hole. Any problem intervals identified while drilling, such as ledges in the Tuffs, will require special care while running casing through. The liner will require 2 straight blade centralizers on every joint. If the liner starts to packoff in the open hole, establish circulation and try to wash through.

The approximate volume will be 300 sacks of Class 'G' with additives as speficied in the casing detail section. DPC Perforating This sidetrack well will require a DPC perforating across the intervals picked from LWD logs. 2-56/BG-01 Drilling Permit Directional Plan #1 1/30/98 SUMMARY PROCEDURE PRE-RIG OPERATIONS 1.

MWD RUNS 1 THROUGH 9 REPRESENT WELL 2-56/EI-01 WITH API# 50-029-22863-00. THIS WELL REACHED A TOTAL DEPTH (TD) OF 17,073 'MD, 10,027 ' TVD. 8. THERE WAS A DESCRIPENCY OF 9' IN THE PIPE TALLY VERSUS CASING TALLY. THIS WAS ALSO EVIDENT WHEN LOGGING, THE GAMMA SHOWS TO BE 9' TO 10' OFF. DUE TO GEOLOGIST'S REQUEST NO DEPTH CORRECTION WAS MADE. LDWG MWD DATA IS DEPTH SHIFTED TO THE SCHLUMBER AIT GAMMA RAY. SROP = SMOOTHED RATE OF PENETRATION WHILE DRILLING. SGRC = SMOOTHED GAMMA RAY COMBINED. SEXP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (EXTRA SHALLOW SPACING). SESP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (SHALLOW SPACING) . SEMP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (MEDIUM S PACING ). SEDP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (DEEP S PACING ) . SFXE = SMOOTHED FORMATION EXPOSURE TIME. SPSF = SMOOTHED COMPENSATED NEUTRON POROSITY. SNNA = SMOOTHED AVERAGE OF NEAR DETECTORS' COUNT RATES. OPEN HOLE CASING DRILLERS BIT SIZE (IN) SIZE (IN) DEPTH (FT) SNFA = SMOOTHED AVERAGE OF FAR DETECTORS' COUNT RATES. SBDC = SMOOTHED BULK DENSITY (COMPENSATED). SCOR = SMOOTHED STANDOFF CORRECTION. SFPE = SMOOTHED FAR DETECTOR ONLY PHOTOELECTRIC ABSORBTION FACTOR. ENVIRONMENTAL FACTORS USED IN PROCESSING NUCLEAR DATA: HOLE SIZE: 8.5" FIXED. MUD WEIGHT: 9.8 TO 10.0 LBS/GAL.
