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/L21" 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.

The wellhead on this well is too high and we cannot place a spacer spool between the tubing head and BOPS. The well has been plugged with a thru tubing cement squeeze of 42 BBLS. The estimated top of cement is 14,663' MD (+/- 1000' above the production packer) and slickline tagged up at 13,825' MD (possible cement sheath). The 4-1/2" tubing and 7" annulus were tested to 2000 psi and the 4-1/2" tubing was cut at 7000'. We would like to nipple up and test the BOPS to 4000 psi high/250 psi low except for the lower pipe rams. Pull and lay down the 7000' of 4-1/2" tubing. Install test plug and test lower pipe rams to 4000 psi high/250 psi low. Dave «Johnson, David A.

Page 1 of 1 2-30A is shut in due to uncompetitive water cut, extremely low oil production and mechanical integrity. After the lower perforations watered out in 2004, multiple isolation, add perf and diagnostic jobs were completed at progressively shallower depths in the well from June 2005 to December 2006. Diagnostic work performed in June 2006 confirmed the water production was from perforations and not leaky plugs or cement channels. The last well test (May 9, 2007) was 5,960 bwpd with 6 bopd with 21.3 mmscfd. The IA/OA communication was demonstrated with an DART in June 2007. A tubing tail plug was subsequently installed to safe out the well in July 2007. No additional oil potential can be documented in this well. The proposed sidetrack is planned to access other resources, repair mechanical integrity and return the well to production. Dave «Johnson, David A.

WELL DETAIL: Current Status: Last TD tag: Latest Drift: Min ID (w/SSSV out): Integrity Issues: Max Deviation: H2S: PROCEDURE: SI well a few days before the job. Significant crossflow is likely between the upper two sets of perfs where the IBP will be set. The longer the well is shut-in, the better chance that this crossflow will subside somewhat. Baker is not concerned with setting the IBP via coil (E-line is a different story) under these dynamic conditions. / 1. RU Unit 5. Bullhead kill well with -200 deg F 2% KCL water. If the HWP cannot get the water to ~OO deg, considering using a hot oil truck. Alternatively, filtered SWat 200 deg F can be used for the bullhead kill. 2. (' MU and RIH with a 10' x 3-3/8" DG and nozzle to drift for the IBP. The plaµ is to set the IBP between the TOF at -18250' and the bottom of the upper perfs 182oo'! Don't anticipate significant debris in any low spots of this slightly undulating well - the 3-1/8" tractor had no problem running to 20,000'. Note that it is desired to tag the TOF, which may be a bird's nest ,./ of 0.39" E-line cable (est 20' above cable head) -- so select BHA accordingly; we don't want the BHA to snag anything. May want to consider a bigger drift so that we don't get beside any cable - maybe a -5' x 3-3/8" DG and a -5' x 3-5/8" Baker weight bar and nozzle. This may feel like an undesirable "anchor" for a first trip in the hole, but again, debris is expected to be / minimal. RIH with drift. Make sure that all fluids going downhole are -200 deg F to minimize wellbore cooling. Tag TOF. Stack a little weight to confirm that we are setting down on something, but don't try to get the fish moving - we don't want to be tempted into a fishing operation. Flag pipe with EOP reference. POOH. If the fish is tagged above -18150' CTM, discuss with John McMullen or Mike Francis before proceeding. ( 3. // MU and RIH with Baker retrievable 3-3/8" IBP and setting tool. Correct depth at flag. RIH to 10' above TOF tag depth determined in step 3 above. Set IBP per Baker rep on location and consistent with the PE Manual recommended practice for IBPs (chase ball with -200 deg F water and wait a minimum of two hours with ball on seat before setting the IBP).

The well has seen a steady decline in production associated with primary depletion since it was completed in 1999. Additional add perf potential exists in the wellbore, and it is recommended to pursue the work at this time. Perf depths will be finalized after reviewing the memory production -- log data. Because of the uniqueness of this 21000' job (requires welding two coil strings together and spooling onto a remotely operated reel), the coil unit will not rig /' down between the production log and the perforating operations. Summary procedure: / 1. Prepare 2" coiled tubing for a 21000' operation. 2. SI well. 3. RU slickline. Pull SSSV. Drift tubing until tools stop due to deviation. 4. Return well to gas lifted production. 5. RU coil unit. Drift well to TD with dummy gun and wash nozzle. MU memory / production logging tools and log well from TD to 200' above top perf. Download data and select final perf intervals. 6. Perforate with 2-7/8" guns. 7. RD coil unit. /' 8. RU slickline and set/test SSSV. 9.

Approximately 600' of Kavik shale was drilled while attempting to get back into the lvashak Sand. Since 500' of producible interval was lost, the decision was made to plug back above the Kavik and redrill the high angle (>75°) portion of the well.

In your letter you reference a letter by ARCO dated October 5th and indicated that ARCO does not object to BP drilling an extended reach well from Endicott MPI into the Prudhoe Bay Unit. ARCO's letter of October 5th was to David W. Johnston, Chairman, of the AOGCC and only indicated that ARCO had reviewed a notice for an exception from the spacing rules set forth in 20 AAC 25.055(a)(3). As to such spacing rule exception, ARCO did indicate in the letter that ARCO had no concern with the drilling of the Duck Island 2-58a/E1-02 Well with regard to that well's proximity to either another well in the pool or the quarter section lines. However, ARCO's letter did state the following: "However, ARCO is concerned with issues relating to development of the pool targeted by the well. As the Commission may know, the subject well is being drilled from a surface location in the Duck Island Unit into a bottomhole location in the Prudhoe Bay Unit. Moreover, the wefl's bottomhole location is adjacent to the Eider Field in the new Eider Participating Area, which was just approved by the Department of Natural Resources on October 1, 1998. From the contents of the PA application and decision, it appears that the subject well is targeting the Eider pool. ARCO also believes that the Eider pool may be in communication with the adjacent lease to the north of the Eider PA. That lease, Tract 75, is co-owned by ARCO and BP, and has three well penetrations. BP has not engaged in any consultation with other potentially affected parties to address the concerns about the complex geology or the commercial and regulatory issues raised by these circumstances. VVhile, ARCO does not object to BP's drilling of the subject well, it has concems about the apparent drive to drill first without addressing issues pertaining to development, correlative rights and existing unit operations. Thus, ARCO reserves its right to raise concerns about whether BP's plans for production and development of the Eider Pool properly prevent waste, protect correlative fights, and insure the greater ultimate recovery of off and gas from the Eider Pool." 1 1998 Gas Cons.

(BPX) by letter dated December 1, 1998 requested an exception to the well spacing provisions of 20 AAC 25.055(a)(3). The exception would allow drilling the Duck Island Unit 2-30a/E1-02 deviated oil well to an unde£med pool with a bottomhole location that is closer than 500 feet to a quarter section line. 2. The Commission published notice of opportunity for public heating in the Anchorage Daily News on December 5, 1998 pursuant to 20 AAC 25.540. 3. No protests to the application were received. FINDINGS: The Duck Island Unit 2-30a/E1-02 oil well will be drilled as a deviated hole from a surface location of 3327' north of the south line (NSL) and 2245' west of the east line (WEL) of Section 36, T12N, R16E, Umiat Meridian (UM) to a bottomhole location 1124' NSL and 303' WEL, Section 28, T12N, R16E, UM. 2.

The 2- is currently drilling from a surface location on the Main Production Island (MPI) in Unit (DIU). As currently planned, production from the well will be allocated on the basis of well testing. BP represents that it will not be possible to separately meter production from the portions of the well that are located within the existing Eider Participating Area of the DIU and PBU Tract 33. BP proposes treating all production from the well as production from the Eider Participating Area. I approve the request to drill the PBU portion of the 2-30a/EI-02 Well. The plan of testing, evaluation, and pilot production of the well (Eider Tract Operation) is approved subject to the following terms and conditions' 1) BP shall notify the Division of Oil and Gas (division) in writing of the completion date of the well, the actual bottomhole location, the interval of the well completed for testing, and the start date of the testing period. 2) This approval is only for a continuous 120 day testing program beginning when the test starts. You must provide a status report of the activities conducted under the Eider Tract Operation to the division by February 1, 1999._ The status report should state whether the 2- 30a/EI-02 Well is capable of producing or contributing to production of hydrocarbons in paying quantities.

The test production, well test information and operations summary from 2-30a/EI-02 should be reported separately with the monthly Sag Delta North Testing Information. 4) Commingling of the test production fluids with Eider Participating Area fluids through the DIU facilities is approved only for the test period. The Eider Participating Area Owners may allocate the test production to the Eider Participating Area on their monthly royalty reports. No field cost deduction will be appropriate for the Eider Tract Operation. 5) For purposes of determining the volume of hydrocarbon production from the PBU eligible for RIK nomination, none of the test production from the Eider Tract Operation will be considered PBU production. 6) The status report due February 1, 1999 should also provide an update of any discussions with the other PBU owners regarding the further development of PBU Tract 33 in the DIU. Assuming that the conditions set forth in this letter are acceptable, you are authorized to proceed.

These wells will be shut in only as required per the Endicott Simultaneous Operations guidelines and Shared Services Drilling close approach 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-09 of 4762 psi at 9,880' TVDss) should range from _+ 9.3 to 9.5 ppg EMW. The presence of gas within the Eider 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 sticking. 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.

This is the second well in the Satellite development plan, therefore, results from this well will further determine the pace of future development drilling. We will have to drill a sidetrack well from well 2-30a/0-09 in the 9-5/8" intermediate casing using the Ultra Slim - hole design (7" drilling liner) and then top setting the reservoir for logging and formation evaluation prior to setting the 4.5" production liner. A standard 8 valve ultra-slimhole (4.5" x 1.5" for 9-5/8" and 4.5" x 1.0" for 7.0" casing) GLM design will be run for the completion on a 4.5" L-80 tubing design with a X/X/XN nipples profile. Directional Plan: The directional plan for the 2-30a/El-02 well consists of cutting the section at 6,500' MD, the drilling 8.5" hole directionally building with conventional BHA's for the build and hold section at 64 to 69°. Current plans call for up to 10°/100' doglegs in this section, but this may be adjusted pending results during the drilling process. After drilling the tangent at 67°, and building directionally back into the Sands with 101° of inclination (inverted profile), the well will be drilled to __.19,925 MD (9,756' 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 unless the published flow rate is to be exceeded. 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 2-30a/El-02 calls for use of Sperry's DWD MWD surveys the entire well. Because of JORPS 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. Bit Program The bit recommendations must facilitate meeting drilling objectives & continuous improvement. We must deliver directional and hole quality requirements, then minimize cost. We will gather directional drilling information for use on future ERD type wells including the daily torque and drag sheet which should be faxed in with the morning reports. 2-30a/El-02 Drilling Permit Directional Plan 2-30a/El-02 Well plan #2 9/30/98 Confidential weliplan Hole Size Bit Type Flow Rate Jets - TFA HHPSI 8.5 GT-LG1XL 600 .557 7.5 '8.5 M40 550 .628 4.9 8.5 ATJ11HD or PDC 550 .628 4.9 8.5 ATJ 11HD 550 .628 4.9 6 STR 20 DX 250 .663 .609 6 STR -09D 250 .663 .609 8 1/2" Intermediate Hole: This interval is characterized by alternating formations of relative drilling ease vs. substantial challenge. For this reason, bit optimization is complex. Our approach is to drill out with a mill tooth bit to achieve maximum ROP & footage while attaining the holding tangent objective. Expect to drill 2500' of SV5/4 to the Top Ugnu, and continue into Ugnu as long as the bit exhibits acceptable ROP and no torque spikes. ROP decline throughout the run will indicate cutting structure loss. We will test the new "XL" hardfacing on the GT-LGlXL and hope to achieve 3500' in 24 hours. Being able to extend the footage at a competitive ROP into the Ugnu will be valuable to the drilling optimization of this interval. Experience in PBU asset may be telling us that the "XL" hardfacing yields increased footage vs. the typical choice of the MFDSH derivatives. This should be a good opportunity to evaluate the potential value. The second bit (stretch) goal would be to drill far enough so that one insert bit can finish the hole to casing point economically. The Ugnu will be the challenge portion of this inrterval. ROP expectation in the Ugnu is 50-70FPH, while attaining the footage requirements including subsequent West Sak, and virtually all the Seabee. The bit would not need to make it to the Tuffs. We expect the third bit (an AT J-11HD) to drill 30 fph, 40 hours, 1200'. The drop interval is 1764' long, identifying the need for the PDC. bit to initiate the 2°/100' drop and drill about 500' of the drop section to 15,200'MD. A trip for LWD is required at least by "200' above THRZ", and would be done during the bit trip. A tradeoff in expected performance exists when comparing heavier vs. lighter set PDC. bit feature/benefits. I recommend the M73PX as the second bit, measure its performance(ROP, directional and durability) both as a function of formation and overall. DS92, M40 and M50 derivatives should be available as back-up bits. The correct back-up bit choice will depend on where the bit would be going into the interval. 6" hole: Drilling out into 400' of Ivishak Zone 2 & 1 sand/shales should drill about 40-50fph(8-10 hrs). PBU sometimes experiences chert in Zone 2C, so watch for rough running after drilling out of the shoe. We recommend a M-20, on a jetted Low Speed motor to produce ,-,80RPM. Minimizing the motor bend angle will improve bit life. Bit footage requirement very well could push one bit to its limit. We might be able to make this interval in one bit run. The drilling risks associated with undergage hole, seal failure, & cone loss increase tremendously after 20 hours in this application. Real time observation and decision making will be required to assess the wisdom of attempting this interval in one rock bit run, or tripping for a second bit. Back-up STR-09D, STR-09DDT, and STR-20DX bits should be available. Drilling Hydraulics Hydraulics parameters must assure that all components of the "system" will function within their requirements. "Preferences" should be accommodated when possible in an effort to optimize for each product to facilitate achieving lowest interval cost. Bit cleaning, hole cleaning and borehole erosion are major considerations, the priority depending on many factors. Establishing cross-flow around 3-cone bits will enhance bit performance, and is achieved by asymmetric nozzling, differences in nozzle relative-height from bottom-hole, or a combination thereof. Your slope bit representative has provided guidelines for bit requirements and preferences. 2-30aJEI-02 Drilling Permit Directional Plan 2-30a/El-02 Well plan #2 9/30/98 Confidential we//plan In the soft formations with the PDC. bi{s., bit cleaning or lack thereof will dramatically effect outcome. GPM to clean the hole @ the expected ROP must be identified. For the 8 ~" hole, a 700psi bit pressure drop is recommended for PDC. bits when in formations which are drillable over 50 fph. Detailed analysis and discussion with the rig team can be accomplished prior to the run in order to discuss the trade-off and establish final nozzle selection. Mud Program: INTERMEDIATE INTERVAL (8-1/2") 6500 to 16,040' After cutting the section and drilling the cement plug out of the casing, treat out the cement contamination and establish filtration and rheological properties using PAC products and Barazan polymer. Maintain the pH in the 9.0 range using caustic soda. Supplement the hole cleaning with regular pumping of Iow/high (consisting of Barazan or N-Vis) viscosity sweeps. If the lo/hi sweeps seem ineffective, 10-12 ppb Barofibre sweeps should be tried. Check with the directional driller and MWD hands prior to pumping Barofibre to ensure their tools won't be effected. The density should start out in the 8.8- 9 ppg range. The weight should be at 9,6 ppg by the top of the West Sak at 11409 MD. Ensure the weight is 10.4 by 15,851 MD for the Tuffs and maintain this weight to TD of this interval. Use all solids control equipment and dilution to hold the weight in the desired range. Begin additions of 3#/bbl each of Baranex and Barotrol at approximately 15,300' MD. This will lower the HTHP filtration rate to <12 cc range and help stabilize any shales encountered. Maintain this range for the remainder of this interval. Maintainence of the TAU 0 in the 6 range will allow minimum flow rates 550 - 600 GPM to clean the hole. If a PDC bit is to be run, pretreat the system with ~% of Condet prior to tripping for this bit to minimize the potential for bit bailing. Maintenance with the Condet at 5 gal/hr is recommended. If Dril-N-Slide is being used for the lubricant cocktail, the Condet additions can be halted as the Dril-N- Slide also acts as a bailing deterent. The high angle/high departure nature of this well will dictate the need for lubricants. The lubricant cocktail is recommended due to it's success at Milne and Niakuk, and needs to be added in a specific order. The following products and concentrations are the components of the cocktail: ~/~-1% Dril-N-Slide,l-2 % EP Mudlube, and 1-2 % Lubetex. A minimum 2 ~/~ % mixture should be tried initially and increased to an absolute maximum of 5% only if the hole dictates it. Sweeps in this section should be pumped every 400' or 6 hours ( which ever comes first). Thirty bbl sweeps will cover 650' of annulus which should suffice. Lo/Hi sweeps should be built out of mud from the active system. The Io sweeps should have the YP lowered to the 6-8 range with Desco or Therma Thin and the hi sweeps should have the YP raised to 50+/- with Barazan or N-Vis. If the lo/hi combination seems inadequate, pump Barofibre/Hi sweeps. The Barofibre sweep should be 15-18 ppb Barofibre added to base mud. Weighted sweeps are sometimes effective but should be kept to the 15-20 bbl size to lessen ECD problems. Weighted sweeps should be mixed in base mud using barite to 2.5 ppg over the system's weight. Adjust the rheology to that of the system with Desco or Therma Thin. If losses have occurred, do not pump weighted sweeps.

The rig should stage in the hole prior to drilling out the 7" casing. The mud weight should be reduced to 9.8 ppg and the pipe rotated on the stage in. This will help "polish" the casing and also give an indication if more EP Mudlube will b,e needed for metal to metal friction in this long section of cased hole. The mud can also be pretreated with bicarb at this time for drilling cement. If more EP Mudlube is needed, maintain a 1~ ppb buffer of bicarb in the mud at all times to counter any high calcium formational fluid, which may be encountered. The calcium level must be kept under 100 ppm at all times. After drilling out, treat out all cement contamination with bicarb, making sure to leave a bicarb buffer in the mud. Establish filtrate control with PAC and/or Dextrid to the 4 or less APl range. Treatments of Baranex and Barotrol should be halted in this hole section. Maintain rheological properties with N- Vis. Maintain pH with caustic soda and run Aldacide G to control bacterial growth ANTICIPATED PROPERTIES Weight Vis YP LSR YP Filtrate pH 9.8 45-60 16-25 5-6 <4 8.5-9.0 Hazards/Concerns: Metal to metal torque. Calcium below 100 ppm. Have ample stocks of LCM. The surface hole will be drilled with high vis spud mud, and sweeps as required for hole cleaning. A dirt Magnet sweep mixed in seawater or brine, followed by a high vis sweep should precede the completion brine. 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 )0 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. Other fields have encountered a "breathing" of the Tuffs when drilling high angle ERD wells. This should be carefully watched and the PVT system calibrated prior to spud. We plan to case the Tuffs immediately after drilling to minimize this potential problem. No potential hazardous levels of H2S are anticipated in the 2-30a/El-02 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. Casing and Cementing This'well will require the Ultraslim-hole design with 9.625" surface casing and 7" drilling 2-30a/El-02 Drilling Permit Directional Plan 2-30a/El-02 Well plan #2 9/30/98 liner. These will be cemented as per cu.rrent recommended practices cementing the surface casing to surface and the intermediate to 2000 feet above the Ivishak. The intermediate casing is being run to facilitate logging and completion of the Ivishak. Intermediate Casing The 7" casing will be set at 16,040 feet. Ens, ure that prior to running long string, that the hole is in good condition and that the mud has been conditioned to run casing. Before POH to run casing 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. Also, 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 casing will use Hydrill 564 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 a crossover for rotation to ream to bottom and while cementing. We also should have a top drive fill up tool to aid in filling the casing while running. The casing 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 casing will require 1 straight blade centralizers on every joint to the 200 feet above the top of the Ivishak at _. 16,471 '. If the casing 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 cementing program is designed to place cement 2000 feet above the top of the Ivishak formation. The approximate volume will be 150 sacks of Class 'G' with additives as specified in the casing detail section. Close attention to detail for this part of the well is critical for the economical success of our drilling program. Production Liner This reservoir section will require a 4.5" 12.6# L-80 liner. This will be hung off in the 7" liner at 16,200 feet. Make sure we have 5000 feet of 3.5" "S" drill pipe to allow for 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, will require special care while running casing through. The liner will require 1 straight blade centralizers per joint of casing. 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 to place cement across the entire liner. The approximate volume will be 75 sacks of Class 'G' with additives as speficied in the casing detail section. Perforating This ERD well will require a wireline perforating across the intervals picked from LWD logs and open hole logs, and will be completed after the rig is released.

Drilling Hazards DRILLING CLOSE APPROACH WELL SHUT-INS The two adjacent wells (2-28/P-19 and 2-32/SN-03) are 10 feet apart at surface, and then diverge with the directional plan. The closest well after the sidetrack is 2-56a/-El-01 which is at 431 feet at a depth of 19,067 feet MD. These wells will be shut in only as required per the Endicott Simultaneous Operations guidelines and Shared Services Drilling close approach 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-09 of 4762 psi at 9,880' TVDss) should range from +_ 9.3 to 9.5 ppg EMW. The presence of gas within the Eider 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 sticking. 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 second well in the Satellite development plan, therefore, results from this well will further determine the pace of future development drilling. We will have to drill a sidetrack well from well 2-30a/0-09 in the 9-5/8" intermediate casing using the Ultra Slim - hole design (7" drilling liner) and then top setting the reservoir for logging and formation evaluation prior to setting the 4.5" production liner. A standard 8 valve ultra-slimhole (4.5" x 1.5" for 9-5/8" and 4.5" x 1.0" for 7.0" casing) GLM design will be run for the completion on a 4.5" L-80 tubing design with a X/X/XN nipples profile. Directional Plan: The directional plan for the 2-30a/El-02 well consists of cutting the section at 6,500' MD, the drilling 8.5" hole directionally building with conventional BHA's for the build and hold section at 64 to 69°. Current plans call for up to 10°/100' doglegs in this section, but this may be adjusted pending results during the drilling process. After drilling the tangent at 67°, and building directionally back into the Sands with 101° of inclination (inverted profile), the well will be drilled to _+19,925 MD (9,756' 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 unless the published flow rate is to be exceeded. 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 tOOlmeeting.COnfiguration, MWD battery life, bit hydraulics will be discussed at the~!.~~,% -~ '~.,, ~.ell,~i~L ~ ~ Directional Survey Program The survey program for 2-30a/El-02 calls for use of Sperry's DWD MWD surveys the~t~? well. Because of JORPS 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. Bit Program The bit recommendations must facilitate meeting drilling objectives & continuous improvement. We must deliver directional and hole quality requirements, then minimize cost. We will gather directional drilling information for use on future ERD type wells including the daily torque and drag sheet which should be faxed in with the morning reports. 2-30a/El-02 Drilling Permit Directional Plan 2-30a/El-02 Well plan #2 9/30/98 Confidential we#plan Hole Size Bit Type Flow Rate Jets- TFA HHPSI 8.5 GT-LG1XL 600 .557 7.5 '8.5 M40 550 .628 4.9 8.5 AT J11HD or PDC 550 .628 4.9 8.5 AT J11HD 550 .628 4.9 6 STR 20 DX 250 .663 .609 6 STR -09D 250 .663 .609 8 1/2" Intermediate Hole: This interval is characterized by alternating formations of relative drilling ease vs. substantial challenge. For this reason, bit optimization is complex. Our approach is to drill out with a mill tooth bit to achieve maximum ROP & footage while attaining the holding tangent objective. Expect to drill 2500' of SV5/4 to the Top Ugnu, and continue into Ugnu as long as the bit exhibits acceptable ROP and no torque spikes. ROP decline throughout the run will indicate cutting structure loss. We will test the new "XL" hardfacing on the GT-LG1XL and hope to achieve 3500' in 24 hours. Being able to extend the footage at a competitive ROP into the Ugnu will be valuable to the drilling optimization of this interval. Experience in PBU asset may be telling us that the "XL" hardfacing yields increased footage vs. the typical choice of the MFDSH derivatives. This should be a good opportunity to evaluate the potential value. The second bit (stretch) goal would be to drill far enough so that one insert bit can finish the hole to casing point economically. The Ugnu will be the challenge portion of this inrterval. ROP expectation in the Ugnu is 50-70FPH, while attaining the footage requirements including subsequent West Sak, and virtually all the Seabee. The bit would not need to make it to the Tuffs. We expect the third bit (an AT-J-11HD) to drill 30 fph, 40 hours, 1200'. The drop interval is 1764' long, identifying the need for the PDC. bit to initiate the 2°/100' drop and drill about 500' of the drop section to 15,200'MD. A trip for LWD is required at least by "200' above THRZ", and would be done during the bit trip. A tradeoff in expected performance exists when comparing heavier vs. lighter set PDC. bit feature/benefits. I recommend the M73PX as the second bit, measure its performance(ROP, directional and durability) both as a function of formation and overall. DS92, M40 and M50 derivatives should be available as back-up bits. The correct back-up bit choice will depend on where the bit would be going into the interval. 6" hole: Drilling out into 400' of Ivishak Zone 2 & 1 sand/shales should drill about 40-50fph(8-10 hrs). PBU sometimes experiences chert in Zone 2C, so watch for rough running after drilling out of the shoe. We recommend a M-20, on a jetted Low Speed motor to produce ,-,80RPM. Minimizing the motor bend angle will improve bit life. Bit footage requirement very well could push one bit to its limit. We might be able to make this interval in one bit run. The drilling risks associated with undergage hole, seal failure, & cone loss increase tremendously after 20 hours in this application. Real time observation and decision making will be re.~luir~ed--to~ass .es~s the wisdom of attempting this ~nte~al ~n one rock b~t run, or tripping for a se~%i~ STR-09D, STR-09DDT, and STR-20DX bits should be available. Drilling Hydraulics Hydraulics parameters must assure that all components of the "system" will f~~ithin their requirements. "Preferences" should be accommodated when possible in an effo~ to optimize for each product to facilitate achieving lowest inte~al cost. Bit cleaning, hole cleaning and borehole erosion are major considerations, the priority depending on many factors. Establishing cross-flow around 3-cone bits will enhance bit performance, and is achieved by asymmetric nozzling, differences in nozzle relative-height from bottom-hole, or a combination thereof. Your slope bit representative has provided guidelines for bit requirements and preferences. 2-30a/El-02 Drilling Permit Directional Plan 2-30a/El-02 Well plan #2 9/30/98 · . ~ Confidential we#plan "--J In the soft formations with the PDC. bits., bit cleaning or lack thereof will dramatically effect outcome. GPM to clean the hole @ the expected ROP must be identified. For the 8 1/2" hole, a 700psi bit pressure drop is recommended for PDC. bits when in formations which are drillable over 50 fph. Detailed analysis and discussion with the rig team can be accomplished prior to the run in order to discuss the trade-off and establish final nozzle selection. Mud Program: INTERMEDIATE INTERVAL (8-1/2") 6500 to 16,040' After cutting the section and drilling the cement plug out of the casing, treat out the cement contamination and establish filtration and rheological properties using PAC products and Barazan polymer. Maintain the pH in the 9.0 range using caustic soda. Supplement the hole cleaning with regular pumping of Iow/high (consisting of Barazan or N-Vis) viscosity sweeps. If the lo/hi sweeps seem ineffective, 10-12 ppb Barofibre sweeps should be tried. Check with the directional driller and MWD hands prior to pumping Barofibre to ensure their tools won't be effected. The density should start out in the 8.8- 9 ppg range. The weight should be at 9.6 ppg by the top of the West Sak at 11409 MD. Ensure the weight is 10.4 by 15,851 MD for the Tuffs and maintain this weight to TD of this interval. Use all solids control equipment and dilution to hold the weight in the desired range. Begin additions of 3#/bbl each of Baranex and Barotrol at approximately 15,300' MD. This will lower the HTHP filtration rate to <12 cc range and help stabilize any shales encountered. Maintain this range for the remainder of this interval. Maintainence of the TAU 0 in the 6 range will allow minimum flow rates 550 - 600 GPM to clean the hole. If a PDC bit is to be run, pretreat the system with 1/~% of Condet prior to tripping for this bit to minimize the potential for bit bailing. Maintenance with the Condet at 5 gal/hr is recommended. If Dril-N-Slide is being used for the lubricant cocktail, the Condet additions can be halted as the Dril-N- Slide also acts as a bailing deterent. The i'iigh angle/high departure nature of this well will dictate the need for lubricants. The lubricant cocktail is recommended due to it's success at Milne and Niakuk, and needs to be added in a specific order. The following products and concentrations are the components of the cocktail: ~2-1% Dril-N-Slide,l-2 % EP Mudlube, and 1-2 % Lubetex. A minimum 2 1,~ % mixture should be tried initially and increased to an absolute maximum of 5% only if the hole dictates it. Sweeps in this section should be pumped every 400' or 6 hours ( which ever comes first). Thirty bbl sweeps will cover 650' of annulus which should suffice. Lo/Hi sweeps should be built out of mud from the active system. The Io sweeps should have the YP lowered to the 6-8 range with Desco or Therma Thin and the hi sweeps should have the YP raised to 50+/- with Barazan or N-Vis. If the lo/hi combination seems inadequate, pump Barofibre/Hi sweeps. The Barofibre sweep should be 15-18 ppb Barofibre added to base mud. Weighted sweeps are sometimes effective but should be kept to the 15-20 bbl size to lessen ECD problems. Weighted sweeps should be mixed in base mud using barite to 2.5 ppg over the system's weight. Adjust the rheology to that of the system with Desco or Therma Thin. If losses have occurred, do not pump weighted sweeps.

The mud weight should be reduced to 9.8 ppg and the pipe rotated on the stage in. This will help "polish" the casing and also give an indication if more EP Mudlube will be needed for metal to metal friction in this long section of cased hole. The mud can also be pretreated with bicarb at this time for drilling cement. If more EP Mudlube is needed, maintain a 1/~ ppb buffer of bicarb in the mud at all times to counter any high calcium formational fluid, which may be encountered. The calcium level must be kept under 100 ppm at all times. After drilling out, treat out all cement contamination with bicarb, making sure to leave a bicarb buffer in the mud. Establish filtrate control with PAC and/or Dextrid to the 4 or less APl range. Treatments of Baranex and Barotrol should be halted in this hole section. Maintain rheological properties with N- Vis. Maintain pH with caustic soda and run Aldacide G to control bacterial growth ANTICIPATED PROPERTIES Weight Vis YP LSR YP Filtrate pH 9.8 45-60 16-25 5-6 <4 8.5-9.0 Hazards/Concerns: Metal to metal torque. Calcium below 100 ppm. Have ample stocks of LCM. The surface hole will be drilled with high vis spud mud, and sweeps as required for hole cleaning. A dirt Magnet sweep mixed in seawater or brine, followed by a high vis sweep should precede the completion brine. 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. Other fields have encountered a "breathing" of the Tuffs when drilling high angle ERD wells. This should be carefully watched and the PVT system calibrated prior to spud. We plan to case the Tuffs immediately after drilling to minimize this potential problem. No potential hazardous levels of H2S are anticipated in the 2-30a/El-02 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. ~ ~- ~,. ? ~ \! i- i ;~ Casing and Cementing Anchorage This well will require the Ultraslim-hole design with 9.625" sudace casing and 7" drilling 2-30a/El-02 Drilling Permit Directional Plan 2-30a/El-02 Well plan #2 9/30/98 liner. These will be cemente~¢as per current recommended practi'ces cementing the surface casing to surface and the intermediate to 2000 feet above the Ivishak. The intermediate casing is being run to facilitate logging and completion of the Ivishak. Intermediate Casing The 7" casing will be set at 16,040 feet. Ensure that prior to running long string, that the hole is in good condition and that the mud has been conditioned to run casing. Before POH to run casing 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. Also, 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 casing will use Hydrill 564 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 a crossover for rotation to ream to bottom and while cementing. We also should have a top drive fill up tool to aid in filling the casing while running. The casing 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 casing will require 1 straight blade centralizers on every joint to the 200 feet above the top of the Ivishak at + 16,471 '. If the casing 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 cementing program is designed to place cement 2000 feet above the top of the Ivishak formation. The approximate volume will be 150 sacks of Class 'G' with additives as specified in the casing detail section. Close attention to detail for this part of the well is critical for the economical success of our drilling program. Production Liner This reservoir section will require a 4.5" 12.6# L-80 liner. This will be hung off in the 7" liner at 16,200 feet. Make sure we have 5000 feet of 3.5" "S" drill pipe to allow for 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, will require special care while running casing through. The liner will require 1 straight blade centralizers per joint of casing. 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 to place cement across the entire liner. The approximate volume will be 75 sacks of Class 'G' with additives as speficied in the casing detail section. Perforating This ERD well will require a wireline perforating across the intervals picked from LWD logs and open hole logs, and will be completed after the rig is released. Confidential wellplan SUMMARY PROCEDURE COMMENTS 1. The 9-5/8 "x 4-1/2" production packer is a TIW permanent packer with a tubing seal assembly above. The packer will not be recovered. 2. The existing perforations will be plugged with cement. 3. This well will be sidetracked at app. 7000 feet. PRE-RIG OPERATIONS 1. RU wireline, Pull the WL SSSV. Drift and dummy off gas lift mandrels. 2. RU and establish circulation down tubing. 3. Pump 100 sx of class G cement and circulate down the tubing. Displace to place cement across perforations from 13,000 to 13,122 MD AND at least 100' above top perf. Squeeze cement if possible up to 1000 psi. 4. RU wireline and cut tubing with chemical cutter above 4.5" x 9-5/8" packer at 11,964' MD. 5. Circulate the 4.5" tubing with 1.5 volumes of sea-water. Check that the well is dead. Freeze protect the top 200' with diesel. Set BPV. Note: Maintain contact with Drilling. If rig move is delayed to more than four days after the well kill, a deeper freeze protect will need to be done by the PE's. 6. Dig out the cellar and level the pad. Inspect the wellhead and tree. Replace the 9-5/8" packoff and function test the LDS's. RIG OPERATIONS (SUMMARY) 1. Mobilize Doyon 15. Review Endicott Simultaneous Operations Plan concerning rig moves. 2. Check that the well is dead. If not circ well w/brine or milling fluid until dead. 3. ND the tree, and NU the BOPE. Test the BOPE and pull BPV. (1/2 day) 4. Screw into the landing joint. Pull and LD the tubing. (1 day) 5. Run and set 9-5/8" wireline bridge plug at +_ 6,600' MD. Set a 17 ppg heavy mud from bridge plug to 6500'. Displace seawater with milling fluid (1/2 day). 6. P/U 9-5/8" section mill BHA and TIH to cut section from 6500' to 6550' MD. POOH with mills (2 days) 7. Place 300 Sack cement plug across section and squeeze into interval at up to 1000 psi. (1/2 day) 8. Pick up Sperry 6.75" directional BHA to turn and build @ 12°/100 feet to 67° at app 6,763' MD. Drill ahead as specified by the rig supervisor to ICP at 16,040. POOH. (12 days) 9. Run a 7" solid liner from 6,350 to 16,040 MD, cement as per plan. (2 days). 10. Pick up Sperry 6." bit and directional BHA to TD at appx 19,925' MD. POOH. (10 days) 11. If there are hole problems, run a HO over whole interval and spot lubricant in OH section. POOH. 12. Run a 4.5" solid liner from 16,200' to 19,925' MD. And cement as per plan(2 days). 14. Make a clean out trip with bit and scraper and displace with KW Brine. 15. Perforate with DPC based on intervals picked from the open hole logs. 16. RIH w/ 7" x 4-1/2" packer, 4-1/2" L-80 tubing, and 8 GLM's to expected setting depth at 16,200' MD. Drift packer, tubing and all jewlery before running. See completion diagram. (1 day) 17. Pump Corrosion inhibitor. Set the 7" packer. Test the tubing to 3500 psi. Test the packer and IA to 3500 psi. (1/2 day) 18. Set the BPV. ND the BOPE, and NU the tree. Shear the RP valve and freeze protect the well. (1/2 day). 19.

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 as required 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 presence of gas within the Eider 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 sticking. 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 second well in the Satellite development plan, therefore, results from this well will further determine the pace of future development drilling. We will have to drill a sidetrack well from well 2-58/SD-09 in the 9-5/8" intermediate casing using the Ultra Slim - hole design (7" drilling liner) and then top setting the reservoir for logging and formation evaluation prior to setting the 4.5" production liner. A standard 8 valve ultra-slimhole (4.5" x 1.5" for 9-5/8" and 4.5" x 1.0" for 7.0" casing) GLM design will be run for the completion on a 4.5" L-80 tubing design with a X/X/XN nipples profile. Directional Plan: The directional plan for the 2-58a/El-02 well consists of cutting the section at 7,000' MD, the drilling 8.5" hole directionally building with conventional BHA's for the build and hold section at 64 to 69°. Current plans call for up to 8°/100' doglegs in this section, but this may be adjusted pending results during the drilling process. After drilling the tangent at 61°, and building directionally back into the Sands with 101° of inclination (inverted profile) , the well will be drilled to +_20,101 MD (9,806' 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 unless the published flow rate is to be exceeded. 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 2-58a/El-02 calls for use of Sperry's DWD MWD surveys the entire well. Because of JORPS 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. Bit .Program The bit recommendations must facilitate meeting drilling objectives & continuous improvement. We must deliver directional and hole quality requirements, then minimize cost. We will gather directional drilling information for use on future ERD type wells including the daily torque and drag sheet which should be faxed in with the morning reports. 2-58a/El-02 Drilling Permit Directional Plan 2-58a/EI-02/Well plan #14 9/11/98 Confidential wellplan Hole Size Bit Type Flow Rate Jets - TFA HHPSI 8.5 GT-LGIXL 600 .557 7.5 8.5 M40 550 .628 4.9 8.5 AT J11HD or PDC 550 .628 4.9 8.5 AT J11HD 550 .628 4.9 6 STR 20 DX 250 .663 .609 6 STR -09D 250 .663 .609 8 1/2" Intermediate Hole: This interval is characterized by alternating formations of relative drilling ease vs. substantial challenge. For this reason, bit optimization is complex. Our approach is to drill out with a mill tooth bit to achieve maximum ROP & footage while attaining the holding tangent objective. Expect to drill 2500' of SV5/4 to the Top Ugnu, and continue into Ugnu as long as the bit exhibits acceptable ROP and no torque spikes. ROP decline throughout the run will indicate cutting structure loss. We will test the new "XL" hardfacing on the GT-LGlXL and hope to achieve 3500' in 24 hours. Being able to extend the footage at a competitive ROP into the Ugnu will be valuable to the drilling optimization of this interval. Experience in PBU asset may be telling us that the "XL" hardfacing yields increased footage vs. the typical choice of the MFDSH derivatives. This should be a good opportunity to evaluate the pOtential value. The second bit (stretch) goal would be to drill far enough so that one insert bit can finish the hole to casing point economically. The Ugnu will be the challenge portion of this inrterval. ROP expectation in the Ugnu is 50-70FPH, while attaining the footage requirements including subsequent West Sak, and virtually all the Seabee. The bit would not need to make it to the Tuffs. We expect the third bit (an AT J-11HD) to drill 30 fph, 40 hours, 1200'. The drop interval is 1764' long, identifying the need for the PDC. bit to initiate the 2°/100, drop and drill about 500' of the drop section to 15,200'MD. A trip for LWD is required at least by "200' above THRZ", and would be done during the bit trip. A tradeoff in expected performance exists when comparing heavier vs. lighter set PDC. bit feature/benefits. I recommend the M73PX as the second bit, measure its performance(ROP, directional and durability) both as a function of formation and overall. DS92, M40 and M50 derivatives should be available as back-up bits. The correct back-up bit choice will depend on where the bit would be going into the interval. 6" hole: Drilling out into 400' of Ivishak Zone 2 & 1 sand/shales should drill about 40-50fph(8-10 hrs). PBU sometimes experiences chert in Zone 2C, so watch for rough running after drilling out of the shoe. We recommend a M-20, on a jetted Low Speed motor to produce---80RPM. Minimizing the motor bend angle will improve bit life. Bit footage requirement very well could push one bit to its limit. We might be able to make this interval in one bit run. The drilling risks associated with undergage hole, seal failure, & cone loss increase tremendously after 20 hours in this application. Real time observation and decision making will be required to assess the wisdom of attempting this interval in one rock bit run, or tripping for a second bit. Back-up STR-09D, STR-09DDT, and STR-20DX bits should be available. Drilling Hydraulics Hydraulics parameters must assure that all components of the "system" will function within their requirements. "Preferences" should be accommodated when possible in an effort to optimize for each product to facilitate achieving lowest interval cost. Bit cleaning, hole cleaning and borehole erosion are major considerations, the priority depending on many factors. Establishing cross-flow around 3-cone bits will enhance bit performance, and is achieved by asymmetric nozzling, differences in nozzle relative-height from bottom-hole, or a combination thereof. Your slope bit representative has provided guidelines for bit requirements and preferences. 2-58aJEI-02 Drilling Permit Directional Plan 2-58a/EI-02NVell plan #14 9/11/98 Confidential we#plan In the soft formations with the PDC. bits., bit cleaning or lack thereof will dramatically effect outcome. GPM to clean the hole @ the expected ROP must be identified. For the 8 ~/~" hole, a 700psi bit pressure drop is recommended for PDC. bits when in formations which are drillable over 50 fph. Detailed analysis and discussion with the rig team can be accomplished prior to the run in order to discuss the trade-off and establish final nozzle selection. Mud Program: INTERMEDIATE INTERVAL (8-1/2") 7000 to 16,369' After cutting the section and drilling the cement plug out of the casing, treat out the cement contamination and establish filtration and rheological properties using PAC products and Barazan polymer. Maintain the pH in the 9.0 range using caustic soda. Supplement the hole cleaning with regular pumping of Iow/high (consisting of Barazan or N-Vis) viscosity sweeps. If the lo/hi sweeps seem ineffective, 10-12 ppb Barofibre sweeps should be tried. Check with the directional driller and MWD hands prior to pumping Barofibre to ensure their tools won't be effected. The density should start out in the 8.8- 9 ppg range. The weight should be at 9.6 ppg by the top of the West Sak at 11409 MD. Ensure the weight is 10.4 by 15,851 MD for the Tuffs and maintain this weight to TD of this interval. Use all solids control equipment and dilution to hold the weight in the desired range. Begin additions of 3#/bbl each of Baranex and Barotrol at approximately 15,300' MD. This will lower the HTHP filtration rate to <12 cc range and help stabilize any shales encountered. Maintain this range for the remainder of this interval. Maintainence of the TAU 0 in the 6 range will allow minimum flow rates 550 - 600 GPM to clean the hole. If a PDC bit is to be run, pretreat the system with ¥~% of Condet prior to tripping for this bit to minimize the potential for bit bailing. Maintenance with the Condet at 5 gal/hr is recommended. If Dril-N-Slide is being used for the lubricant cocktail, the Condet additions can be halted as the Dril-N- Slide also acts as a bailing deterent. The high angle/high departure nature of this well will dictate the need for lubricants. The lubricant cocktail is recommended due to it's success at Milne and Niakuk, and needs to be added in a specific order. The following products and concentrations are the components of the cocktail: 4/2-1% Dril-N-Slide,l-2 % EP Mudlube, and 1-2 % Lubetex. A minimum 2 ~/~ % mixture should be tried initially and increased to an absolute maximum of 5% only if the hole dictates it. Sweeps in this section should be pumped every 400' or 6 hours( which ever comes first). Thirty bbl sweeps will cover 650' of annulus which should suffice. Lo/Hi sweeps should be built out of mud from the active system. The Io sweeps should have the YP lowered to the 6-8 range with Desco or Therma Thin and the hi sweeps should have the YP raised to 50+/- with Barazan or N-Vis. If the lo/hi combination seems inadequate, pump Barofibre/Hi sweeps. The Barofibre sweep should be 15-18 ppb Barofibre added to base mud. Weighted sweeps are sometimes effective but should be kept to the 15-20 bbl size to lessen ECD problems. Weighted sweeps should be mixed in base mud using barite to 2.5 ppg over the system's weight. Adjust the rheology to that of the system with Desco or Therma Thin. If losses have occurred, do not pump weighted sweeps.

Monitor pit volumes and flow closely. 2-58aJEI-02 Drilling Permit Directional Plan 2-58a/EI-02NVell plan #14 9/11/98 Confidential wellplan Maintain an adequate stock of LCM on location at all times. PRODUCTION INTERVAL (6") 16,369 to 20,101' MD The rig should stage, in the hole prior to drilling out the 7" casing. The mud weight should be reduced to 9.8 ppg and the pipe rotated on the stage in. This will help "polish" the casing and also give an indication if more EP Mudlube will be needed for metal to metal friction in this long section of cased hole. The mud can also be pretreated with bicarb at this time for drilling cement. If more EP Mudlube is needed, maintain a 1/2 ppb buffer of bicarb in the mud at all times to counter any high calcium formational fluid, which may be encountered. The calcium level must be kept under 100 ppm at all times. After drilling out, treat out all cement contamination with bicarb, making sure to leave a bicarb buffer in the mud. Establish filtrate control with PAC and/or Dextrid to the 4 or less APl range. Treatments of Baranex and Barotrol should be halted in this hole section. Maintain rheological properties with N- Vis. Maintain pH with caustic soda and run AIdacide G to control bacterial growth ANTICIPATED PROPERTIES Weight Vis YP LSR YP Filtrate pH 9.8 45-60 16-25 5-6 <4 8.5-9.0 Hazards/Concerns: Metal to metal torque. Calcium below 100 ppm. Have ample stocks of LCM. The surface hole will be drilled with high vis spud mud, and sweeps as required for hole cleaning. A dirt Magnet sweep mixed in seawater or brine, followed by a high vis sweep should precede the completion brine. 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. Other fields have encountered a "breathing" of the Tuffs when drilling high angle ERD wells. This should be carefully watched and the PVT system calibrated prior to spud. We plan to case the Tuffs immediately after drilling to minimize this potential problem. No potential hazardous levels of H2S are anticipated in the 2-58a/El-02/Eider-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. Casing and Cementing This well will require the Ultraslim-hole design with 9.625" surface casing and 7" drilling liner. These will be cemented as per current recommended practices cementing the surface casing to surface and the intermediate to 2000 feet above the Ivishak. The intermediate casing is being run to facilitate logging and completion of the Ivishak. Intermediate Casing 2-58aJEl-02 Drilling Permit Directional Plan 2-58a/EI-02/Well plan #14 9/11/98 Confidential wellplan The 7" casing will be set at 16,369 feet. Ensure that prior to running long string, that the hole is in good condition and that the mud has been conditioned to run casing. Before POH to run casing 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. Also, 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 casing will use Hydrill 564 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 a crossover for rotation to ream to bottom and while cementing. We also should have a top drive fill up tool to aid in filling the casing while running. The casing 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 casing will require 1 straight blade centralizers on every joint to the 200 feet above the top of the Ivishak at _+ 16,471 '. If the casing 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 cementing program is designed to place cement 2000 feet above the top of the Ivishak formation. The approximate volume will be 150 sacks of Class 'G' with additives as specified in the casing detail section. Close attention to detail for this part of the well is critical for the economical success of our drilling program. Production Liner This reservoir section will require a 4.5" 12.6# L-80 liner. This will be hung off in the 7" liner at 16,200 feet. Make sure we have 5000 feet of 3.5" "S" drill pipe to allow for 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, will require special care while running casing through. The liner will require 1 straight blade centralizers per joint of casing. 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 to place cement across the entire liner. The approximate volume will be 75 sacks of Class 'G' with additives as speficied in the casing detail section. Perforating This ERD well will require a wireline perforating across the intervals picked from LWD logs and open hole logs, and will be completed after the rig is released. 2-58a/El-02 Drilling Permit Directional Plan 2-58a/EI-02/Well plan #14 9/11/98 Confidential wellplan SUMMARY PROCEDURE COMMENTS 1.
