These KOP's may be altered to enhance reservoir contact depending on the angle of intersection of each zone. b) Place 1 RA tag above each window exit. RA tags to be spaced out ~40 - 80' above window depth except on the OBd lateral. It will need to be placed 120' above the casing shoe. c) Emergency 7--5/" casing slips can be used instead of the 7-5/a" mandrel hanger if required for space out. 7-°/e" String Centralizer Placement a) Centralizer size: 7 b/a" X 9-%8" (this is different then the norm of/a" under gauge hole) b) Do not run centralizers on the window joints spaced at the top of each sand. c) Place 2 rigid straight blade centralizers back to back at the very bottom of the shoe joint. Do not run any centralizers on the next two full joints. d) With the exception stated above, alternate 1 rigid straight vane cenralizer floating across a full joint and 2 rigid straight vane centralizers, one floating on the upper half of the joint and one floating on the lower half of the joint separated by a stop collar up to 6,482' MD (Top Nb). Then continue with 1 rigid straight vane centralizer per joint floating to 5,465' MD (500' MD above Ma sand). Zonal isolation with cement is required between the OA and the Nb sands. The centralizer program is subject to change pending modeling and hole conditions. 4'/z" Solid Liner Centralizer Placement a) Run one straight blade rigid centralizer per joint, floating between the collars. If any differential sticking is noticed while drilling, it may be necessary to put another centralizer per joint separated by a stop collar. Do not put any centralization on the first two joints above the bent joint. Well Control Well control equipment consisting of 5,000 psi working pressure pipe rams (2), blind/shear rams, and annular preventer will be installed and are capable of handling the maximum potential surface pressures. Based upon calculations below, BOP equipment will be tested to 3,500 psi. Due to test pressures not exceeding S,000psi it will not be necessary to have two sets of pipe rams installed at all times.

The Schrader in the Polygon 1A fault block is expected to be normal pressured at 8.5-8.6 ppg EMW. This pressure is estimated based on offset well pressures and material balance. II. Hydrates and Shallow gas A. Gas Hydrates are expected at L-pad near the base of the permafrost. Setting casing through the SV1 should keep hydrate exposure from extending past the surface hole. Recommended practices and precautions for drilling hydrates should be followed in the surface hole. Occasionally hydrates are encountered below the SV1. III. Lost CirculationJBreathing A. Lost circulation is not expected at the L-Pad fault. In addition the fault will be crossed at high angle and move away quickly. B. We do not expect breathing on this well. IV. Kick Tolerance/Integrity Testing A. The 10-3/4" casing will be cemented to surface. B. The 10-3/4" casing test pressure is 3500 psi. C. The Kick Tolerance for the surface casing is 50 bbls with 9.0 ppg mud, 11.2 ppg LOT, and an 8.8 ppg pore pressure. D. 9-7/8" Openhole Integrity Testing -LOT to a minimum of 11.2 ppg EMW 20' from the shoe. E. The 7-5/8" intermediate casing will be cemented with 15.81b/gal tail cement to 500' MD above the Ma sand C~3 5,465' MD. F. The 7-5/8" casing test pressure is 3500 psi. G. The Kick Tolerance for the intermediate casing is infinite with 9.0 ppg mud, 10.5 ppg FIT, and an 8.8 ppg pore pressure. H. 6-3l4" Openhole Integrity Testing -FIT to a minimum of 10.5 ppg EMW 20' from the shoe. V. Stuck Pipe A. We do not expect stuck pipe if the hole is kept adequately clean. VI. Hydrogen Sulfide L Pad is not designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. No measurable H2S is being produced from the formation at this time. However 10 ppm is measured regularly at L pad as a result of the use of Ivishak gas lift gas. All L pad gas lift wells will likely have H2S in this concentration. Note that all injection has been with produced water not seawater.

Confirm this requirement prior to the rig moving over the well. Verify that the Diverter does not require any additional spacer spools as well. - Ensure the AOGCC receives 24-hour advance notification of the diverter test and subsequent BOP tests. - L-200 will have to be shut in and require wellhouse removal before rig can be moved over the well. All surface flowlines and gas lift lines will need to be depressurized to header pressure. Discuss the move at a pre-job safety meeting and designate a spotter to ensure there is no danger of a collision. - L Pad is not designated as an H2S site, however Standard Operating Procedures #or H2S precautions should be followed at all times. No measurable H2S is being produced from the formation at this time. However 10 ppm is measured regularly at L pad as a result of the use of Ivishak gas lift gas. All L pad gas lift wells will likely have H2S in this concentration. Note that all injection has been with produced water not seawater. H2S levels are expected to remain low until the waterflood matures. Recent H2S data from the pad is as follows: Adjacent producers at Surface: Adjacent producers at TD: L-02 10 ppm L-101 5 ppm L-116 10 ppm Reference SOP: • "Drilling/ Work over Close Proximity Surface and Subsurface Wells Procedure" Job 2: Drill 13-'/2" Surface Hole Critical Issues: - Well Design: The Slimhole well design was adopted due to the production GLM / downhole pressure gauge requirements. This well design also gives us greater flexibility on junction design and reduces ECD's. - Surface Hole Problems: At L-Pad, no significant surface hole drilling problems have been identified. Tight hole, bridging, and obstructions have been encountered while drilling the Permafrost. In only one case has an obstruction caused the well to be sidetracked. Lost circulation has not been a problem on L-pad. Some minor tight hole has also been encountered below the Permafrost. Hydrates are present at L-pad from the base of the Permafrost all the way through the SV-1 sand and should be treated with conventional practices: pretreating mud, cooling mud, increasing weight, etc. - Close Approach: No wells are required to be shut in. There are several close tolerance wells in the surface interval between 300' - 1,700' MD. Follow the traveling cylinder / no-go plot per established procedures. Magnetic interference is expected to be nonexistent by 1,000' MD. - Directional: Every effort should be made to ensure a `smooth' well profile that will benefit torque / drag in the later hole sections. A graduated build profile is planned. Objective is to keep DLS 51.5° over planned. - Hole Cleaning: Surface rotary speeds should be maximized wherever possible. The BHA is limited to 60 to 80-rpm while drilling because of the 1.5° motor bend. Vary flowrates 400-650 GPM to achieve the required directional response. However it will be possible at TD to raise the rotary speed to +100- rpm prior to POOH to run casing. At this time flowrates should., be increased to 650 - 700 GPM to increase hole cleaning. - Tight spots: During short trips, work out any tight spots as they are seen while pulling out of the hole instead of waiting and reaming them out after running back in the hole as this could lead to accidental sidetracking. Consider backreaming across initial tight spots only if washing does not alleviate the problem. 9 Permit to Drill 09/23/04 - Faults: There is one fault that will be crossed in the surface hole section: .Fault Location MD TVD TVDss Throw Direction Uncertainty Fault #1 - SV6 1,285' 1,277' 1,200' S0' to 70' West +/- 150' MD - Critical LWD Tools: It is critical for the landing of this hole section to have the GR to pick the top of the SV1 sand. If this tool fails, it will require an immediate trip out of the hole to replace. It is imperative that the surface casing isolates the upper section of the SV1 sands. In order to do this the casing will need to be set --100' TVD below the top of the SV1 sand in the shale. Reference RPs: • "Prudhoe Bay Directional Guidelines" • "Well Control Operations Station Bill" • Follow Schlumberger logging practices and recommendations Job 3: Run 10-3/4" Surface Casing Critical Issues: - Casing to bottom: It is imperative the casing is set in the shale below the SV1 sands to ensure wellbore integrity for the intermediate interval. It may be desirable to stop and roll the mud over half way in the hole to break the gels and reduce surging intensity on the SV sands. This will also help to ensure circulation is attained at TD at the desired cementing rates without losses. Make sure that the hole is clean and obstructions are minimized before running casing as higher doglegs and aggressive directional work could make casing running more difficult. - Casing drift: 10-3/a" special drift casing is being used. Ensure that casing equipment is properly drifted to ensure adequate ID for the 9-'/a" bit, i.e. float equipment, casing hanger, etc. - Cement to surface: A single-stage job will be done on this well using 250% excess in the permafrost and 30% excess below the permafrost. A TAM Port collar will be placed at 1,000-ft MD as a contingency. - Losses during cement job: Lost circulation has been experienced on L-Pad and on offset pads while running and cementing surface casing on past wells. The expected frac gradient for the shale below the SV1 sands is 12.5-Ib/gal EMW. Follow the Schlumberger recommended pumping rates as they have modeled the expected ECD's during the entire cement job to help mitigate the potential for breaking down the formations. Reference RPs: • "Casing and Liner Running Procedure" • "Surface Casing and Cementing Guidelines" • "Surface Casing Port Collar Procedure" Job 4: Drill 9'/8" Intermediate Hole Critical Issues: - Differential Sticking could be a problem if lost circulation is occurring or if the drill string is left stationary for an extended period or time across the permeable Schrader Sands. - LOT: Perform a LOT (minimum 11.2 ppg EMW to satisfy kick tolerance). The Kick Tolerance for the surface casing is 50 bbls with 9.0 ppg mud, 11.2 ppg LOT, and an 8.8 ppg pore pressure (most likely 8.6 ppg based on recent MDT's within the block). If the LOT is less then 11.2 ppg EMW, then the kick tolerance will be < 50 bbls. Based upon off-set drilling data on L-Pad, a minimum leak-off of 12.5 ppg is expected at the 10-3/a" shoe. ECD's at the shoe are expected to be in the 10 ppg range while drilling at the shoe and at TD of the well. - Penetration Rate: Penetration rates should not exceed 600 fph instantaneous. This should allow for ECDs not to exceed 0.6ppg above calculated. If ECDs are sustained above this threshold, it is advised that drilling should be stopped and the hole circulated before continuing. ECD should not exceed 11.0 ppg once the M sand has been penetrated. 10 Permit to Drill 09/23/04 • • - 7-s/e" casing landing point: The landing point for the 7 5/.° casing will be determined by isopaching down to the top of the OBd sand based on changes in GR/Res curves associated with the tops of the previous OB sands. Top setting the OBd will give us the most possible amount of TVD to work with when landing the 6-3/a" horizontal. If tops are coming in 100' or more out from prognosis, then conduct a short trip and notify town. A Rigsite Geologist will be required on site to pick casing point. - Torque: Use lubricants as per the MI program as necessary. If weight transfer problems are encountered during sliding, attempt to circulate and rotate for a minimum of 2 bottoms up to test if lubricants are truly needed or if the hole is loading up with cuttings. - Critical LWD Tools: It is critical to have the GR tool in order to pick the landing point for this hole section. The landing of this well will depend on picking the top of the OBd sand which will be picked by Gamma Ray. If we loose the GR tool, we will need to trip for it. - Faults: There is one fault that will be crossed in this hole section: Fault Location MD TVD TVDss Throw Direction Uncertainty Fault #2 - UG3 5,171' 3,597' 3,520' 40' to 50' South +!- 150' MD - Bowl Protector: With the larger than normal production hole size (9-7/8"), the bowl protector will be very thin. Pull and inspect the bowl protector whenever possible. Replace with any sign of damage. Take caution not to get bowl protector stuck. - Directional Constraints: It is critical to not let the angle get any higher then planned, due to slickline access requirements and junction requirements. It is critical to design a BHA to minimize inclination and walking tendencies and thus minimize wellbore tortuousity. DLS should be kept <_1 ° over planned. - Tight spots: During short trips, work out any tight spots as they are seen while pulling out of the hole instead of waiting and reaming them out after running back in the hole as this could lead to accidental sidetracking. If a tight spot is encountered, run back in the length of the BHA and circulate for at least 30 minutes at max rotation speed and max flowrate while reciprocating at max allowable speed without exceeding the ECD limit. Reference RPs: • "Standard Operating Procedure for Leak-off and Formation Integrity Tests" • "Prudhoe Bay Directional Guidelines" • "Lubricants for Torque and Drag Management" • "ERD Operating Practices" Job 6: Run and Cement 7-g/8" Intermediate Casing Critical Issues: - Cement Job: It is imperative to achieve a good cement job on this well for Nb sand and junction isolation requirements. Good zonal isolation of these sands is imperative to the production success of this well. Therefore reciprocate pipe as long as possible while cementing. A USIT log will be run to confirm the quality of the cement job between the sands if any problems are encountered during the cement job. Keep cementing ECD's below 12.5 ppg EMW during the displacement. - Casing Space out: There are 3 important space out zones for this casing run: o There must be a long full joint of casing just starting above the top of the OA and OBa sands so that the multi-lateral junction window can be milled out as close to the top of the respective sands in the top/middle of a full joint of casing. Run full casing joints across the OA and OBa sands. Any casing pup joints required for space out should be placed below the base of the sands. o The shoe must be within 10 feet of the bottom when the casing is cemented in place. o The mandrel hanger must be spaced out correctly at surface if it is to be used. Emergency slips may be used if necessary to achieve proper space out. 11 Permit to Drill 09/23!04 • • - Freeze Protection: Ensure the lower production cement has reached at least a 706C thickening value prior to freeze protecting. After freeze protecting the 7 S/s" x 10-3/a" casing outer annulus with dead crude to 2,200'TVD, the hydrostatic pressure will be 7.8 ppg vs 8.5 ppg EMW of the formation pressure immediately below the shoe. Ensure adouble-barrier at the surface on the annulus exists until the cement has set up for at least 12 hours. Trapped annulus pressure may be present after pumping the dead crude as the hydrostatic pressure of the mud and crude could be 100 psi underbalance to the open hole. - Centralization/Differential Sticking: See centralizer strategy above. Differential Sticking could be a problem if lost circulation is occurring or if the casing is left stationary for an extended period or time across the permeable sands. Ensure the casing is centralized across any permeable zones if the casing is left stationary while running in the hole. - RA Tags: There will need to be 4 RA tags placed in the 7-b/8" casing for depth control. Placement strategy is -40 - 80' above each of the windows: Pip #1: OA window, Pip #2: OBa window, Pip #3: OBb window, Pip #4: 120' above the shoe. - Mud Requirements: Thin the mud as per MI's Mud Program. The thinner the mud the better displacement is achieved and the better the cement job will be. Extra time spent circulating is warranted to ensure optimum mud properties and hole cleaning prior to the cement job. - Franks Casing Fill-up tool: Make sure that a casing fill up tool is on location prior to PU 7-s/8" casing. - TIW Valve: Ensure that a TIW valve with a cross over to 7-%" BTC casing is on the rig floor Reference RPs: • "Intermediate Casing and Cementing Guidelines" • "Freeze Protecting an Outer Annulus" • "ERD Operating Practices RP" Job #7 /Job #10 /Job #15 /Job #20: Drill 6-3/a" Laterals (OBd / OBb / OBa / OA Sands) Critical Issues: - MOBM: The production intervals will be drilled with a 9.2 ppg VersaPro MOBM. This fluid has been utilized before on past wells, however it has inherent HSE issues associated with its handling and thus all safety procedures should be refreshed. Review the 8P MOC, the Nabors Hazard Analysis, and the MI drilling fluids program prior to utilizing this fluid. - Faults: There are no planned fault crossings in any of the laterals intervals. - Geosteering: Geosteering in these lateral intervals is expected to be the most challenging aspect of this well. Anadrill AIM will be used and should help mitigate some of this challenge. A 1.5° bent housing motor will be used to help proactively make corrections quicker to avoid unnecessary undulations throughout this interval. There will be a rigsite geologist on location to help with interpretations. o The structure of the horizontal section is expected to be relatively flat for the first -2,000' and then is expected to drop between 1.5 - 2.5° apparent dip depending on how the actual structure tracks the prognosis. o The well L-202 OBd lateral is designed to undulate in 2 1!2 cycles across the 30 foot vertical extent of the OBd net sand/pay section along the length of the L-202 polygon. The undulating well profile will provide low angle offtake points from all sands in the OBd net sand/pay interval and crosscut potential vertical permeability barriers. o The L-202 OBb lateral will target to stay near the center to lower half of the 13-14 foot vertical extent of the OBb net sand/pay section along the length of the L-202 polygon. However, given the thin character of the OBb target interval, it is likely the drillstring will undulate across the entire OBb net sand thickness several times along the length of the drilling polygon. Dip information gained from drilling the underlying OBd lateral leg should help minimize unplanned excursions out of the OBb target interval. 12 Permit to Drill 09/23/04 • • o The L-202 OBa lateral will be targeted to drill the first 1/3 of the total polygon length in the lower sand and second 2/3's of the polygon in the upper sand. By limiting the drilled length in the lower sand to only the upstructure polygon area, it is possible that a lighter updip fraction of the lower OBa oil column may be contacted. Well L-202L2 will then ramp up into the upper OBa sand and finish drilling the lateral in the thicker sand and lighter oil of the upper OBa interval. o The OA lateral is designed to undulate in 1 1/2 cycles across the OA net sand interval along the length of the up-structure L-202 OA polygon. The L-202 OA lateral was shortened relative to the underlying laterals to maintain standoff from wet OA sands in the interval between the L-216 and L- 210P61 wells. o The directional plans for each lateral should reflect the iearnings derived from the previous laterals but should only be used as a guide and real time adjustments will need to be made to stay within the sands. If for whatever reason we become lost, steer up as hard as possible to determine where within section we are. Once we are able to determine where we are, then we can go back and OH sidetrack. - Surveying: Survey density is critical to achieve vertical positional certainty. It is recommended to survey every 30-45' to ensure accurate vertical positional certainty throughout the horizontal section. This survey density should alleviate the errors associated with vertical section creep. - ECD/Hole Cleaning: Utilize PWD to monitor for good hole cleaning and ECD trends. Cuttings will tend to dune up at the window due to hole geometry. Planned ECD hardline 12.0 ppg EMW. - Target Constraints: The North sidelines of the polygon are defined as hard lines due to standoff to injection. The South sidelines of the polygon are defined as hard lines due to fault proximities. Do not extend beyond the endline points due to potential downdip water.

Liner on bottom will also prevent the sand from collapsing, keeping the entire drilled section in tact, thus capturing all of the reserves possible for this section length. - Centralizer Placement (5-3/d' OD): o See centralizer strategy above Do not run any in the liner lap. - 4-~/z" Rams: Keep VBR's in.

This will allow for a better window and allow for easier access into the window with the bent joint on the end of the 4-'/2" liner. Exact window depth to be based oft of actual logs. Depth control will be very critical on these windows. Space out tubulars below the whipstock may be required to properly position the whipstock at the correct depth while landing out on the ZXP liner top packer used on the previous lateral. A discussion will need to take place to determine the best way to gain accurate depth control for the window setting depth. o Planned OBb window depth is 7,113' MD (4,500' TVD). o Planned OBa window depth is 6,980' MD (4,452' TVD). o Planned OA window depth is 6,783' MD (4,377' TVD). - Window Milling: It is critical to have a smooth uniform full length window. Extra time spent on the window milling will be well worth it when it comes time to land out the hook hanger. Follow the BOT representative during the milling of the window. - Milling Assembly: In the past debris barrier cups have been sliced in order to allow flow bypass while POOH while retrieving whipstocks. From now on, the assembly will be run without slicing the cups and an unloader sub will be run below the debris barrier to facilitate flow by the swab cups and prevent swabbing. No seals below the whipstock unless fluid losses have been observed. - Whipstock Setting: On past wells, only one shear was observed during the whipstock setting procedure. This introduced some uncertainty as to whether or not the slide was oriented correctly. The most likely explanation for this is that on high angle wells cased hole friction may cause the 15-20K bottom trip and the 35K whipstock shear to occur simultaneously. - Hole Cleaning: Well inclination at the planned kick off points is between 65° - 70°. In addition, the wellbore tangent angle above the KOP's has a 61 ° tangent section prior to building up to 87°. Good window milling and hole cleaning practices will be critical to ensure that metal and formation cuttings are removed from the well. Cuttings will tend to dune up at the window due to hole geometry. - FIT: AN FIT is only required on the first lateral. Therefore the mills will only need to be drilled down far enough to ensure an adequate window and not to ensure 20' of open hole below the bottom of the window.

Liner on bottom will also prevent the sand from collapsing, keeping the entire drilled. section in tact, thus capturing all of the reserves possible for this section length. Current modeling for the OBa liner, based on historical data, we should have plenty of SO weight required to land the junctions. Data collected on the OBd liner iob will be utilized to double check the calibration of the model prior to running the OBb liner to confirm additional weight pipe requirements. o If problems are encountered while RIH with the liner call ODE while reciprocating liner and discuss options: • Stop and reposition weight pipe and pick up more if available and try again. • Stop and POOH and make a cleanout run with a hole opener. • Stop and POOH to liner running tool and LD some footage of liner depending on modeling results based on actual drag data. - Liner Swivel: On past wells it was determined that the tension lock liner swivel between the Hook Hanger and the liner was not necessary because the torque needed to orient the Hook with the liner did not present any difficulties landing the junction. The decision has been made to continue with this strategy even on wells with as much as 7,300' of liner (L-201). The swivel requires adequate weight in order to lock it out and allow the liner and the hook to rotate together. Without enough weight acting on the swivel, the bent joint on the bottom of the liner will not be able to be manipulated from surface to facilitate access out into the window. - Centralizer Placement (5-3/a" OD): Run one straight blade rigid centralizer per joint, floating between the collars. If any differential sticking is noticed while drilling, it may be necessary to put another centralizer per joint separated by a stop collar. Do not put any centralization on the first two joints above the bent joint. - 4-~/z" Rams: Keep VBR's in.

Tubing side barriers will be provided via TIW and kill weight fluid. o Once packer is set the annulus above the packer will be tested to 3,500 psi to verify packer/annulus integrity. Kill weight fluid and the tubing hanger provide additional annulus side barriers. At this point the ball and rod with kill weight fluid and a TIW valve comprise the tubing side barriers. o When the DCK valve is sheared a casing annulus valve must be in place along with kill weight fluid to provide sufficient annular barriers. Tubing side barriers are still kill weight fluid on ball and rod and a TIW. 15 Permit to Drill 09/23/04 o A TWC will be installed and tested from above to 1,000 psi for 30 minutes prior to nippling down the BOP's.

With the TWC in place BOPs can be nippled down and the tree nippled up. o With the tree nippled up freeze protecting removes the kill weight fluid as a barrier. We then count on the tree for tubing side barriers, and two casing annulus valves for annulus side protection. o Before rigging down a BPV tested from below to 1,000 psi will be left in the tubing hanger to provide an additional tubing side barrier once the rig is off. Since the DCK valve is still open it will be necessary to leave one casing annulus valve and a VR plug for annular barriers. Make sure that a lubricator is used to install the VR plug while both casing annulus valves are still in place. - Thread Dope: BOL 2000 NM or BOL 2000 is the BP approved thread compound for Carbon API connections. All IBT-M pipe should arrive on location with one of these two thread compounds. It would still be good practice to look over each connection in the pipe shed prior to incorporating them into the tally. - Shear Valve: We will run a DCK shear valve in the GLM directly above the production packer to utilize for freeze protecting after the production packer is set. - Phoenix Pressure Gauge: A downhole pressure gauge with control lines will be run on this well. Ensure that a Baker Centrilift hand and a Schlumberger completions hand (Camco) is on location prior to PU tubing to allow them time to get all of their equipment in order and confirm its working condition. o HSE: Sheaves hung in the derrick and I-wire spools will be utilized during the running of the completion, make sure that this non-routine operation is discussed in length at the PJSM with all relevant personnel prior to PU completion. o Place 1 cannon clamp per joint for the first 10 joints followed by 1 clamp per every 2 joints to surface. o Test the 1-wire connection at regular intervals while running in the hole. If the I-wire is damaged in any way contact ODE. - Contact the Field AOGCC Rep with 24 hours of notice to witness the tubing and annulus pressure tests. Reference RPs: • "Completion Design and Running" RP • "Tubing Connections" RP Job #24: ND/NU/Release Rig Critical Issues: - See Job 1 for adjacent well spacing. Identify hazards in a pre-move meeting, and take every precaution to ensure good communication prior to beginning the rig move. Use spotters when moving the rig. - Diesel: Diesel will be used to freeze protect the well. The diesel flash point is 100° F. Diesel vapor pressure is - 0.1 psia at 100° F.
