The New Targets and PBTD BHL are: (per attached Directional Plan WP#11) Target 1:X=688,465 (E), Y=5,967,641 (W) 574 FSL, 3122 FEL, SEC. 12, TllN, R14E Target 2:X=688,277 (E), Y=5,967,762 (W) 699 FSL, 3307 FEL, SEC. 12, T1 iN, R14E PBTD BHL: X=687,881 (E), Y=5,967,767 714 FSL, 3702 FEL, SEC. 12, TllN, R14E Current Well Status: Drilling in progress in 8.5" intermediate hole at 6400'MD with planned TD of 8.5" interval at 10741 MD in siltstone at base of Kingak. Unchanged Drilling Objective: Shared Services Drilling was granted a Sundry to resume operations on Well L2-07 on 10- 28-98. Operations resumed on November 4, 1998 and are currently in progress. As permitted, L2-07 is planned as a Zone lB producer, Conventional s-shaped well, targeting a DS 18 B HL. Operations were Shutdown on this grassroots well on Sept 03, 1998 after setting 9-5/8" casing at 4434' MD, 3745'TVD. The original surface hole and casing operations were performed by Doyon 9. As permitted, the intermediate hole will be 8.5" with 7" intermediate casing. The production interval will be 6" to TD. This well will be completed with a 4.5" L-80 solid cemented liner and 4.5" L-80 tubing. The proposed conventional well will access an untapped E-W trending graben. The previously approved well program has been changed to optimize target exposure within the graben polygon and standoff from boundary faults. I Well Name: IL2-07 (L2/18-07) Drilling Operations Note: L2-07 was spudded on Aug 28, 1998, with surface casing set on 9-1-98 @4434'MD, 3745'TVD. A 4.5", L-80, 12.6# IBT tubing freeze protect string was set from surface to 2041'. The tree was NU and the well circulated to diesel. Operations were suspended on 9-3-98. Operations will resume with Doyon 16. The well is a conventional S-shape, targeting DS-18 BHL in a graben in Zone 1B. All shallow close approaches, which required no shut-ins, were cleared bY setting surface casing.

Centralize with 3 bow spring centralizers, positioned across shouldered connections or stop collars to allow some float to prevent "bailing" them up, and DO NOT RECIPROCATE PIPE. Pipe reciprocation can cause surge and swab of pressurized gas/water zones, res. ulting in influx, or sloughing shale! The result has been liners stuck off bottom, packoffs, and problems with running tools. The min- mum centralization, reflects the success of using this procedure to re-run a stuck liner on our previous well.

Drilling Fluids Program Surface Interval (Completed) I Surface (12-1/4" hole) Section: Spud Mud I 8.5" Fluid Basis of Design: Summarized in the headers, this fluid is designed to optimize fluid mechanics in conjunction with monitoring drilling practices with the Sperry Drilling Optimization Tools. Additionally, because of the narrow margins between loss or gain, the fluid is designed to deliver Iow ECDs/Surge/Swab with maximum inhibition and hole cleaning at very Iow flow rates. 8.5" INTERMEDIATE HOLE FLUID: 6% KCL,'$PV,'['LSRV, 5% LUBETEX, SECD,,I, Jet Vel, ,[,AVs, ,I, HIS Use Shale Stabilizers in Make Fluid and Minimum "Select" Low PV Starch Per Previous Pilot Tests For This Fluid Density, ppg LSRV CPS PV/YP Gels pH FL, cc (Range,~ 9.6-10.0 Ugnu 60-80K Drilling PV 8-12, < 15 10 sec > 18 9 - 9.5 APl 3-6cc 10.6-10.8 WS/Put River 9.8 - 10.8+ 150K Sweeps & YP Expected Range 10 min > 22 8.5 - 9.0 HPHT -.. <10c~ PUT RIVER Liner Running Pill 50-60 Hazards & Concerns: H2S, Put River, Directional, Hole Cleaning, Cretaceous Water Injection Flows, Tight Hole, Packoffs, Stuck Pipe, Surge & Swab of Shallow Gas, Problem Kingak, etc. Within 1400' of the shoe, at the top of the Ugnu, we will have to be at 10.0 PPG (4720'ss, 5800'MD), and at 10.8 PPG by the time we reach the top of the WS, 3000' out of the shoe @ 7400'MD, & 5800'ss. The Put River is @8030'ss, .-.10,507'MD and is expected to require 10.5-10.8 to prevent influx. To avoid losses, utilize control drilling, reduced pump rate 150-200'AV. (150'AV being used in 12.25" & 8.5" hole sections @ 150'ROP and up to >70 degrees; Maunder/Mallow, Rose, MPU, 10-98). Trickle in Liquid Casinq in Ugnu / West Sak to seal off permeable zones. Monitor & record losses. Find a used fluid or junk mud to drill out ES cementer, contaminated 9.2 ppg mud below ES ce- menter, and float shoe. Swap over to good fluid when returns are clean to drill new hole footage for LOT/FIT. Pick Tri-Cone benchmark bit, or Smith or Hughes challenge bit with submission of Bit Challenge Sheet. Drillout with standard gel-free 6% KCI sidetrack fluid with black products &low PV starch for inhibi- tion, and xanthan (Barazan-D) for suspension & transport. Pilot test fluid to get desired properties. This is standard formulation used for D-16 Kingak drilling, employing Barite for density, and adjusting Iow PV starch to maintain Iow PV. General: When CBU, keep pipe moving/rotating and break out a single or rack back a stand every hour to prevent hole washout. Utilize 150K sweeps and short trips for ROP/hole cleaning. Use a 150K liner running pill w/5% Lubetex. Keep AV below 200'min, and size jets for jet vel < 200 ft/sec. Control drill Ungnu & West Sak Sands to avoid hole erosion, mini- mize fluids loss, and washout problems. If sands start running at 45 degrees, keep track of solids generated & cuttings hauled away to correlate to hole washouts. Track any losses. Utilize the Sperry Drilling Optimization Tools to minimize Surge/Swab, improve hole cleaning IF SWABING, STOP & DISCUSS SAFETY MARGINS & MONITOR WELL FOR FLOW.

This fault will not be drilled. The wellbore will drop angle through the base Kingak to achieve this objective; control drilling practices should prevent problems. Disposal Cuttings should be hauled to the ball mill at CC-2A. Fluid Handling: Haul all drilling and completion fluids and other class I! wastes to CC-2A for injection. Haul all Class I wastes to Pad 3 for disposal. In addition, haul all cuttings from drill- ing operations to CC-2A for disposal. DRILLING DISCUSSION OBJECTIVE/SCOPE' L2-07 (L2/1 8-07) is part of Facility Sharing work among partners to utilize Lisburne Facilities and surface locations to access Drillsite 18 Developrn'ent Plan Targets. L2-07 is planned to target an East West, fault-bounded graben, as a Zorie lB producer. It is a conventional S- shaped grassroots well, with maximum hole angle of 55 degrees, to maintain wireline access. Surface casing was set by Doyon 9 on Sept 3, 1998, @ 4434'MD, and 3475'TVD, into the top of the SV3. Doyon 16 will continue the work, drilling to intermediate casing point and running 7" 26# L-80 IBT MOD 10' into the Siltstone at the base of the Kinqak (,-..10,741'MD, 8243ss'ss). This is to prevent losses into the Saq with hiqh density fluids or while cementinq, and has been used effectively. This siltstone has required a careful geologic pick to confirm The intermediate casing program will bring cement tail 1000'MD above the PUT River @ 10,523'MD (TOC Tail = 9,522'MD). The top of the lead cement will cover 1000'MD above the Cretaceous water- flood influx at 4725'ss. The 6" Production hole will be in the base of ZlB @ 11,286-11,478'MD or 8654'ss-8764ss. The well will be completed with a 4.5", 12.6//L-80, IBT-MOD liner, ce- mented with the Modified Liner Cementing Procedure. The completion string will be 4.5" L-80, 12.6#, IBT-MOD tbg, with SSSV @ 2200', 3 1" Pocket GLMs @3500'ss, 6100'ss, and 7969'ss. Additionally, the tailpipe will employ only one X nipple to allow for future CT side- tracks, with the tailpipe stung into the top of the liner WLEG. (Reference the Proposed Com- pletion Diagram) The intermediate hole section is full of potential variations, with shallow gas & water flows, overpressure in the Put River, and problematic shales, tight hole, stuck pipe and other notice- able historical notations on the Pad Data Sheet. The well has an AFE of $2.711M and is estimated to take 24 days. Surface Hole Drill Out and LOT or FIT Test After drilling out surface casing and 20'-50' of new hole perform a LOT to 13 PPG EMW per RP. If the formation does not break down, convert to FIT. If the LOT is Iow, below 11 ppg, no- tify the ODE. At 13 ppg, the kick tolerance is 86 bbls of gas height influx. Hole Problems L2 & DS 18 have a long history of shallow gas, H2S up to 2000 ppm (Lisburne Wells only), Cretaceous Water Flows, Put River overpressure, lost circulation, wellbore instability, tight hole, bailing, swabbing, & stuck pipe, especially in the Kingak. With today's Optimization Tools and level of awareness of Drilling Practices these problems should be mitigated. Take all precautions and note in the Well Plan and on the Pad Data Sheet approximate location of known problem areas and history. Bit Program The intermediate hole will be drilled out from surface with a tri-cone bit/BHA and is expected to drill to dull somewhere in the hard Ugnu streaks. The next assembly will be a PDC bit with the motor designed to optimize bit performance: minimal bit vibration, steerability, hydraulic jet velocity and H-S-I reduced to prevent hole washout, and reduced flow rates, adequate for suspension, but reduced to lower ECD, etc. The Optimization Logging Tools will be picked up on this run (PWD/Sonic Caliper/DDS Vibration). It is expected that Optimization Logging Tools will continue to define benefit, especially in control of surge/swab/ECD/& Vibration induced pump rate, and drilling practices (drillstring and casing/liner rotation, running speed, and string design.) PDC bit design has indicated that less aggressive bits avoid vibration and steering problems. The 6" is to be drilled with a benchmarktri-cone insert bit, or alternative w/Bit Chal- lenge Sheet. MWD/LWD Logging, Optimization Logs, & Perforations Logging requirements for each hole section are specified in the preceding section. Addition- ally, Drilling Optimization Tools (PWD/Sonic Caliper/DDS Vibration) will be picked up for the second bit run in intermediate hole, matched up with an engineered PDC/BHA with modified motor. In Field Reference will be applied to all MWD measurements to improve assurance an accuracy, especially to greatly reduce the uncertainty of hitting a complex, fault-boundedqra- ben, which miqht otherwise result in high possibility of numerousplugbacks. This is a service which does not involve downhole tools, or time & risk associated with gyro. In addition to the MWD/LWD, the 6" hole will be DPC logged with PEX & Sonic. Perfs will be picked from these logs. Perforations will utilize 2.75" guns, 200 psi underbalance, and should be done through the perf pill left in the well after cementing. Barriers & Recommended Practices Per SSD Drilling Policy, all drilling operations must maintain redundant isolation inside produc- tion strings and in annuli. This insures that there are always 2 independent barrriers to flow. Two barriers are required while installing and/or removing trees or BOPE. Any variation will require dispensation from the Drilling Superintendent. in H2S Make certain all PPG, placards, etc., are in place and in compliance with HSE H2S guidelines. These guidelines have recently been updated and are available on the Intranet. Confirm that H2S monitors which are in place cancel the need for individual personal monitors as stated in the most recent HSE documentation for H2S wells. Operations Procedure Summary Pre-Rig: Wells Group 1. A Pre-Rig & Shut-In Memo was sent to the Wells Group. A Pre-Rig Checklist and Hando- ver is to be completed, reviewed, and signed before MIRU. 2. There are no surface shut-ins listed. The Wells Group will coordinate the removal of the wellhouse and the pad preparation. Drilling Rig Procedure 1. Perform Pre-Rig inspection with Pad Operator. Obtain handover notes and status of well, ensuring that all wellhead pressures are zero. 2. MIRU. NU and test BOPE. Circulate out freeze protection & decomplete the well by pull- ing and laying down 2041' 4.5" L-80 12.6//IBT freeze protect string. 3.

Utilize Drilling Opti- mization Tools to maintain wellbore integrity. Do not exceed 12 ppg ECD on any opera- tion, including tripping & connections, watch monitor, bring pumps on slowly. If swab e<- ceeds safety margin STOP, monitor for flow, and adjust running speed. 5. Bring fluid density to 10 ppg by 4720'ss, top of Ug4, and Cretaceous waterflood influx pt. Be alert for surface flows from the time you drill out the shoe to TD. The WS has flowed at 10.5+, so be at 10.8 ppg by 5825'ss, 7432 TVD. The Put River has shown similar pressures and is expected @ 10,523'MD, 8030'ss. 6. Control drill as indicated to maintain wellbore stability, integrity, and directional profile. Reference the ECD 12 ppg max for all ops and minimum swab to prevent influx, watch ~the monitor on the rig floor, carefully and consult with Sperry. 7_ Conditon well at TD, (siltstone @ base of Kingak) pumping sweeps before and after short trips, and leave a liner running pill on bottom (150K & 5% LT). Rack back stands every hour while CBU to prevent hole erosion shown on DS 6-10A caliper logs. 8. Space out to land casing, leaving no Kingak exposed, if necessary set on slips. Not recip- rocating, and modified centralization, will reduce risk of having casingslough in shale and stick off bottom, as in DS6-10A, and achieve the goal of a shoe w/no exposedKingak. 9. Run 3 bowspring centralizers, drop water spacer, use viscosified MCS-4D spacer, and do not reciprocate due to surqe & swab. (Bow springs should float around stop collars or co~- nections.) 10. As soon as cement is in place, land casing, RILDS, energize packoffs, & pump down the backside ('w/HB&R?) to clear any cement from surface annulus and to pump down 2200' of diesel. 11. Test 7" casing to 3000 psi for 30 minutes. 12. PU 6" section BHA w/MWD/GR/RES, drill out landing collar and displace to 6% KCI Quik- driln mud for FIT, pressuring to 0.5 ppg over fluid density. 13.

L2-07 is planned to target an East West, fault-bounded graben, as a Zor~e lB producer. It is a conventional S- shaped grassroots well, with maximum hole angle of 55 degrees, to maintain wireline access. Surface casing was set by Doyon 9 on Sept 3, 1998, @ 4434'MD, and 3475'TVD, into the top of the SV3. Doyon 16 will continue the work, drilling to intermediate casing point and running 7" 26# L-80 IBT MOD 10' into the Siltstone at the base of the Kinqak (,.,10,741'MD, 8243ss'ss). This is to prevent losses into the Sag with hiqh density fluids or while cementing, and has been used effectively. This siltstone has required a careful geologic pick to confirm The intermediate casing program will bring cement tail 1000'MD above the PUT River @ 10,523'MD (TOC Tail = 9,522'MD). The top of the lead cement will cover 1000'MD above the Cretaceous water- flood influx at 4725'ss. The 6" Production hole will be in the base of ZlB @ 11,286-11,478'MD or 8654'ss-8764ss. The well will be completed with a 4.5", 12.6# L-80, IBT-MOD liner, ce- mented with the Modified Liner Cementing Procedure. The completion string will be 4.5" L-80, 12.6#, IBT-MOD tbg, with SSSV @ 2200', 3 1" Pocket GLMs @3500'ss, 6100'ss, and 7969'ss. Additionally, the tailpipe will employ only one X nipple to allow for future CT side- tracks, with the tailpipe stung into the top of the liner WLEG. (Reference the Proposed Com- pletion Diagram) The intermediate hole section is full of potential variations, with shallow gas & water flows, overpressure in the Put River, and problematic shales, tight hole, stuck pipe and other notice- able historical notations on the Pad Data Sheet. The well has an AFE of $2.711M and is estimated to take 24 days. Surface Hole Drill Out and LOT or FIT Test After drilling out surface casing and 20'-50' of new hole perform a LOT to 13 PPG EMW per RP. If the formation does not break down, convert to FIT. If the LOT is Iow, below 11 ppg, no- tify the ODE. At 13 ppg, the kick tolerance is 86 bbls of gas height influx. Hole Problems L2 & DS 18 have a long history of shallow gas, H2S up to 2000 ppm (Lisburne Wells only), Cretaceous Water Flows, Put River overpressure, lost circulation, wellbore instability, tight hole, bailing, swabbing, & stuck pipe, especially in the Kingak. With today's Optimization Tools and level of awareness of Drilling Practices these problems should be mitigated. Take all precautions and note in the Well Plan and on the Pad Data Sheet approximate location of known problem areas and history. · Bit Program The intermediate hole will be drilled out from surface with a tri-cone bit/BHA and is expected to drill to dull somewhere in the hard Ugnu streaks. The next assembly will be a PDC bit with the motor designed to optimize bit performance: minimal bit vibration, steerability, hydraulic jet velocity and H-S-I reduced to prevent hole washout, and reduced flow rates, adequate for suspension, but reduced to lower ECD, etc. The Optimization Logging Tools will be picked up on this run (PWD/Sonic Caliper/DDS Vibration). It is expected that Optimization Logging Tools will continue to define benefit, especially in control of surgelswablECDl& Vibration induced pump rate, and drilling practices (drillstring and casing/liner rotation, running speed, and string design.) PDC bit design has indicated that less aggressive bits avoid vibration and steering problems. The 6" is to be drilled with a benchmarktri-cone insert bit, or alternative w/Bit Chal- lenge Sheet. MWD/LWD Logging, Optimization Logs, & Perforations Logging requirements for each hole section are specified in the preceding section. Addition- ally, Drilling Optimization Tools (PWD/Sonic Caliper/DDS Vibration) will be picked up for the second bit run in intermediate hole, matched up with an engineered PDC/BHA with modified motor. In Field Reference will be applied to all MWD measurements to improve assurance an accuracy, especially to greatly reduce the uncertainty of hitting a complex, fault-boundedgra- ben, which might otherwise result in hiqh possibility of numerousplugbacks. This is a service which does not involve downhole tools, or time & risk associated with gyro. In addition to the MWD/LWD, the 6" hole will be DPC logged with PEX & Sonic. Perfs will be picked from these logs. Perforations will utilize 2.75" guns, 200 psi underbalance, and should be done through the perf pill left in the well after cementing. Barriers & Recommended Practices Per SSD Drilling Policy, all drilling operations must maintain redundant isolation inside produc- tion strings and in annuli. This insures that there are always 2 independent barrriers to flow. Two barriers are required while installing and/or removing trees or BOPE. Any variation will require dispensation from the Drilling Superintendent. 10 H2S Make certain all PPG, placards, etc., are in place and in compliance with HSE H2S guidelines. These guidelines have recently been updated and are available on the lntranet. Confirm that H2S monitors which are in place cancel the need for individual personal monitors as stated in the most recent HSE documentation for H2S wells. Operations Procedure Summary Pre-Rig: Wells Group 1. A Pre-Rig & Shut-In Memo was sent to the Wells Group. A Pre-Rig Checklist and Hando- ver is to be completed, reviewed, and signed before MIRU. 2. There are no surface shut-ins listed. The Wells Group will coordinate the removal of the wellhouse and the pad preparation. Drilling Rig Procedure 1. Perform Pre-Rig inspection with Pad Operator. Obtain handover notes and status of well, ensuring that all wellhead pressures are zero. 2. MIRU. NU and test BOPE. Circulate out freeze protection & decomplete the well by pull- ing and laying down 2041' 4.5" L-80 12.6# IBT freeze protect string. 3. Make up BHA #2 w/Tri-Cone, and a used or disposable fluid to drill out ES cementer, 9.2 ppg mud between ES & shoe, shoe & cement. When circulated clean, displace to new fluid for intermediate hole, drill 20-50' new hole for LOT/FIT to 13 PPG. Drill ahead w/Tri- Cone until dull. Trip for BHA#3 w/drillinq Optimization Tools & PDC bit. 4. Drill 8.5" hole per directional plan to interval TD @ ,--,10,741'MD, 8243'ss, 10' into theSilt- stone at the base of the Kingak -Do not penetrate Sag @ ,.- 8253'ss Utilize Drilling Opti- mization Tools to maintain wellbore integrity. Do not exceed 12 ppg ECD on any opera- tion, including tripping & connections, watch monitor, bring pumps on slowly. If swab e<- ceeds safety margin STOP, monitor for flow, and adjust running speed. 5. Bring fluid density to 10 ppg by 4720'ss, top of Ug4, and Cretaceous waterflood influx pt. Be alert for surface flows from the time you drill out the shoe to TD. The WS has flowed at 10.5+, so be at 10.8 ppg by 5825'ss, 7432 TVD. The Put River has shown similar pressures and is expected @ 10,523'MD, 8030'ss. 6. Control drill as indicated to maintain wellbore stability, integrity, and directional profile. Reference the ECD 12 ppg max for all ops and minimum swab to prevent influx, watch __the monitor on the rig floor, carefully and consult with Sperry. 7_ Conditon well at TD, (siltstone @ base of Kingak) pumping sweeps before and after short trips, and leave a liner running pill on bottom (150K & 5% LT). Rack back stands every hour while CBU to prevent hole erosion shown on DS 6-10A caliper logs. 11 8. Space out to land casing, leaving no Kingak exposed, if necessary set on slips. Not recip- rocating, and modified centralization, will reduce risk of having casingslough in shale and stick off bottom, as in DS6-10A, and achieve the goal of a shoe w/no exposedKingak. 9. Run 3 bowspring centralizers, drop water spacer, use viscosified MCS-4D spacer, and do not reciprocate due to surge & swab. (Bow springs should float around stop collars or c~- nections.) 10.As soon as cement is in place, land casing, RILDS, energizepackoffs, & pump down the backside (w/HB&R?) to clear any cement from surface annulus and to pump down 2200' of diesel. 11. Test 7" casing to 3000 psi for 30 minutes. 12. PU 6" section BHA w/MWD/GR/RES, drill out landing collar and displace to 6% KCI Quik- driln mud for FIT, pressuring to 0.5 ppg over fluid density. 13. Drill to TD ---11,314'MD, base Zone lB. Condition hole for logs DPC logs w/liner pill. 14. RIH w/E-line logs (Platform Express & Sonic), log from TD @'11,314'MD to 7" shoe. 15. Run 4-1/2", 12.6#/ft, L-80 liner. Use "Modified Conventional Liner Cementing" Program. TOL @ ,-,10,634'MD, set with hanger & liner top packer. (No inner string) Per RP release from liner running tool with 1,000 psi, and circulate the long way with the drill-in fluid until returns are clean, then displace to seawater before POOH. 16. Pressure test to 3000 psi for 30 minutes. 17. Perf with DPC Halliburton 2.75"guns @ 200 psi underbalance through perf pill. 18. RU run 4.5" 12.6# L-80 IBT Mod completion with "X" nipple in tailpipe assembly/x lock mandrel w/ball seat for setting production pkr, 3 GLMs (1 ") (top w/RP shear), & SSSV @ ~2200'. The X nipple tailpipe allows for maximum CTD access. 19. Land tubing hanger & RILDS, spaced out to position tailpipe inside liner WLEG. Reverse circulate filtered SW w 25 gal/100 bbls Corexit. Take care not to shear RP in top GLM. 20. Drop packer setting ball. Set the packer and test the tubing to 3500 psi for 30 min, annulus to 3000. Shear RP by bleeding down tubing slowly. Install hanger plug, set TWCV in tub- ing hanger and test from the annulus to 1000 psi. 21. ND stack NU tbg head adaptor flange & FMC Gen IV tree. Test to 5000 psi. Remove TWCV w/DSM lubricator. 22.

This grassroots well will consist of drilling a 12 ¼" surface hole with 9 5/8" casing. The intermediate hole will be 8 ¥2" with 7" intermediate casing. The production interval will be 6" to TD. This well will be completed with a 4- 1/2" L-80 solid cemented liner and 4-1/2" L-80 tubing. The proposed conventional well will access an untapped E-W trending graben. Objective: The forward plan is to drill surface hole to -4488'MD. Run 9 5/8" casing and cement back to surface as planned. Doyon 9 will then suspend operations on L2-07. Doyon 9 will be laid down and modified for the move to the Alpine development project for ARCO. Well L2-07 will be completed with Nabors 7ES by mid-October. The previously approved well program will be used to drill the intermediate and production intervals. The BHL will not change. Revision After running, cementing and testing the 9 5/8" surface casing: 1. Test 9 5/8" casing to 3000psi for 30 min. We will not drillout shoe at this point. 2. MU 3,000' of 4 1/2" tubing below the tbg. hanger. 3. Freeze protect the permafrost zone (+ 2,500') with diesel. 4. Land hanger in tubing head. Test hanger. 5. Install BPV. Nipple up a dry hole cap with valve. Test same to 5000 psi. 6. Release rig to Doyon/ARCO. STATE OF ALASKA ALASK%~131L AND GAS CONSERVATION C0~IMISSION APPLICATION FOR SUNDRY APPROVAL 1.
