The submitted suspended well inspection reflects the current condition of the well (reference 20 AAC 25.110 (f)) and supports the request for renewal of suspension. Recent events from this well indicate that this well is mechanically sound. Specific attachments include: Suspended Well Site Inspection form documenting the site condition. Wellbore diagram illustrating the current configuration of the well. Orion well NWE4-01 was suspended on 04/07/2002 and has future utility as an exploration well tied to O- pad and I-pad development. The strata through which the well was drilled is neither abnormally geopressured nor depleted. The well is secured with unperforated casing and liner and a cement plug at 9005 MD. The well is mechanically sound as proven by a passing pressure test of the 9.625 casing, 4.5 liner and cement on 04/02/2002 to 3500 psi. Based on these conditions and the inspection on 07/04/2025, Orion well NWE4-01 meets the provisions required in 20 AAC 25.110 (a)(1). Hilcorp North Slope, LLC requests approval for renewal of the existing suspension status for this well. Attached is an Application for Sundry Approval (10-403) with a technical justification summarizing the information on the current status and condition of the well (reference 20 AAC 25.110 (a), (b), (e), (h)). In summary, Hilcorp believes Orion well NWE4-01 is mechanically sound and secure and meets the requirements for renewal of suspended status. If you have any questions, please call me at 406-570-9630 or Oliver Sternicki at 907-564-4891.

The well was drilled from an ice pad adjacent to the Milne Point access road to better understand the resource potential in the western part of the Prudhoe Bay unit. The well is mechanically sound and secured with unperforated casing and liner and cement as proven by a passing pressure test to 3500 psi after the 4.5 liner was run. The well will not allow the migration of fluids, will not damage freshwater or producing or potentially producing formations, will not impair the recovery of oil or gas, and is secure, safe and not a threat to public health. The strata through which the well was drilled is neither abnormally geo-pressured nor depleted. Condition of the Wellhead and Surface Location Orion well NWE4-01 is not located on a pad and is situated approximately 400 east of the Milne Point access road on the tundra. The surrounding area is in good condition. There is no discoloration and no sheens around the well or on nearby water. The well pressure readings are T/I/O= BPV (kill string)/ 0 psi/ 0 psi Request Hilcorp North Slope, LLC requests approval for renewal of the existing suspension status for NWE4-01. All hydrocarbon intervals are isolated and there are no underground sources of fresh water in this area.

The well was drilled from an ice pad adjacent to the Milne Point road to better understand the resource potential in the western part of the Prudhoe Bay Unit. BP Exploration (Alaska), Inc. (BPXA) completed a suspended well inspection of PBU NWE 4- 01 on 09/22/10. The results of that inspection were submitted with a Report of Sundry Well Operations (form 10 -404) on 10/06/10. The well is secured with casing and cement and is not perforated. The well is mechanically sound as proven by a pressure test to 3500 psi after the liner was run. The well will not allow the migration of fluids, will not damage freshwater or producing or potentially producing formations, will not impair the recovery of oil or gas, and is secure, safe, and not a threat to public health. The strata through which the well was drilled is neither abnormally geo- pressured or depleted. --J7---A final development strategy has not been determined for this area. The well has potential - future utility for surveillance, a pilot study or inclusion in a small satellite pad. Condition of the Wellhead and Surface Location Having been drilled from an ice pad, PBU NWE 4 -01 is not located on a gravel pad and there are no pits at the location. There is no discoloration near the well site or in nearby water. During the inspection, it was noted that the well sign was missing. A new sign will be ordered and placed at the well. The current well pressure readings are T /I /O = SSV /0/0. ,/ Request BPXA requests approval for renewal of the existing suspension status for PBU NWE 4 -01. A variance to the provisions of 20 AAC 25.110 (c) (2) is also requested under 20 AAC 25.112 (i) to allow the well to be remain suspended in its current condition. All hydrocarbon intervals are isolated and there are no underground sources of fresh water in this area. MLB 12/03/10 • s .

The targeted Schrader Bluff interval contained a hydrocarbon net pay which justified running the 7" intermediate casing and drilling ahead in the 6-1/8" inverted section of the well. Over the weekend, this 6-1/8" section was drilled to TO. Current plans are to run and cement a 4-1/2" liner, and suspend the well as outlined in the permit to drill. As per our discussion, there is no additional paperwork that is required for the planned suspension besides the standard Completion Report, form 10-407. Thanks for your help, and please call with any questions. William 5.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. A weekly status report is required from the time the well is spudded until it is suspended or plugged and abandoned. The report should be a generalized synopsis of the week's activities and is exclusively for the Commission's internal use. The 12 ~" hole between 110' and 2758' MD must be logged using GR / Resistivity / Neutron / Density / Dipole Sonic. Mudlog and Samples not required in NWE 4-01. Annular disposal has not been requested as part of the Permit to Drill application for NWE 4-01. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

The data is not required by BP and is not seen as information that will "significantly add to the geologic knowledge of the area". Permit Discussion Topics / The proposed NWE 4-01 location lies between the ongoing Kuparuk and Schrader Bluff development at Milne Point S-Pad and Borealis / Orion L-Pad. Immediate off-set penetrations include exploration wells NWE 2-01, NWEileen-1, 33-29E and Texaco Prudhoe-01. All are believed to have complete mud logs of the lithology encountered, and at surface the proposed NWE 4-01 location is approximately 3160' from NWE 2-01 (see attached maps for details on project location). Based upon the close proximity of the data obtained on these off- set wells, along with the extensive logging program planned for this well, it is believed that additional mud logging data is not critical to the geologic knowledge of the area. Proposed Suspension Condition NWE 4-01 is being drilled as an appraisal well for the Schrader Bluff Orion accumulation. Information gathered from this well will help determine the reservoir's future development requirements. The well is being planned as a "keeper", and is part of the future development plan. The surface location was selected based upon a potential gravel pad design and is positioned within a future row of wells on that design. This is similar to the practice used when drilling the NWE 1-01 A and 1-02 exploration wells, which are currently in service as L-1 00 and L-101. As outlined in the below drill and complete summary, the base plan is to suspend the well without perforating or .,,/' completing the well. A kill string will be run to below the permafrost and the wellhead secured for suspension. (See attached schematic for additional details). If the well fails to encounter hydrocarbon reserves that justify future development plans, the well will be plugged and abandoned as per AOGCC regulations.

Shallow Gas Hazards I Abnormal Pressure -' Local seismic data shows no sign of shallow gas hazards within the NWE 4-01 wellpath, and offset drilling data confirms this interpretation. No seismic anomalies were seen at the nearest analogue well (NWE 2-01) or at the proposed NWE 4-01 location. /' Offset data also indicates no abnormally pressured intervals are to be expected in the planned NWE 4-01 drilling program. Estimated pore pressures for formations to be penetrated are shown above and are based upon RFT /' pressure samples taken in offset wells. The closest offset well NWE 2-01 (drilled in 1998) encountered no abnormally pressured zones, and drilled the Ugnu and Schrader intervals with a 9.3 ppg mud. Offset data does reveal the presence of hydrates near the base of the permafrost, however, only minor problems have been associated with the hydrates encountered in these offset wells. On the nearest offset well NEW 2-01 the total gas units increased, however there was not even a cut in mud weight at the shakers. When a hydrate zone is encountered, the relative warmth of the drilling mud will decompose the hydrates and / gasify the mud. The hydrates adjacent to the wellbore will continue to decompose and gasify the drilling mud as long as drilling operations continue to introduce heat into the hydrate-bearing interval. While encountering shallow hydrates has been known to cause severe problems in other parts of the world, this occurrence is well known and handled frequently in nearby Prudhoeßay and Milne Point. Reduced flow rates (where applicable), keeping the mud cool, and the addition of Lecithin to the mud, are three proactive safety measures that will be employed in the drilling operation. These actions continually prove to be sufficient when gas hydrates are encountered in nearby Prudhoe Bay wells. The drilling rig for NWE 4-01 will be equipped with the following gas detection systems to monitor shallow gas and/or hydrates: . Rig gas sensors located at the pits, cellar, & rig floor . PVT system . Trip tank .

NEW 4-01 Permit to Drill 2/27102 Page 7 ) ) Job 1: MIRU Hazards and Contingencies ~ The rig move will involve no surface close approach hazards with adjacent wells. The NWE 4-01 well will be drilled from an ice pc;1with no other wellheads or conductors on the location. ~ H2S is not expected in the area or to be encountered during the planned drilling operations. PVT samples taken from the Schrader Bluff OA and OBd intervals in off-set wells L-117 and V-100, found no H2S present (January 2002). Also, the nearest off-set well NWE 2-01 encountered no H2S during the original drilling operations back in March of 1998. Nevertheless, Standard Operating Procedures for H2S precautions should be followed at all times. Job 2: Drill Surface Hole Hazards and Contingencies ~ No fault crossing are expected in the surface interval. A small fault has been identified -350' MD below the planned surface hole TD, however the fault has been identified as a low risk for lost circulation. ~ There are no close approach issues along the NWE 4-01 well path. The nearest well is NWE 2-01 which /~ is -3160' well-to-well at surface. ~ Gas hydrates have been observed in a majority of the nearby wells. Typically, hydrates are encountered near the base Permafrost and extend down to the SV1 sand. Hydrates will be minimized by pre-treating the mud system with Driltreat (Lecithin). Additional measures included reduced flow rates of -500 to 550 gpm and keeping the mud temperature cool «60 degrees if possible). The immediate off-set well NWE 2-01, encountered minimal hydrates through-out the surface hole section. Refer to Baroid mud recommendation. ~ Associated with the hydrates, is the danger of deeper gravel beds below the Permafrost that will tend to sloughWwhen aerated gas cut hydrate mud is being circulated out. Maintain adequate viscosity. (Milne Point has encountered stuck pipe from this situation.) ~ Seismic data indicates no abnormally pressured shallow gas zones within the surface hole interval. Job 3: Install 9-5/8" Surface CasinQ Hazards and Contingencies / ~ It is critical that cement is circulated to surface for well integrity. 250% excess cement through the permafrost zone (and 300/0 excess below the permafrost) is planned. As contingency, a port collar will be run in the casing at -1000' MD to allow circulating cement to surface if the single stage is unsuccessful. ~ Cementing practices on the surface casing should meet the below criteria to allow for any potential annular injection permitting approval, during the future Orion development. 1 . Pipe reciprocation during cement displacement 2. Cement - Top of tail >500' TVD above shoe (or to base permafrost) using 30% excess. 3. Casing Shoe Set approximately 100'TVD below SV-1 sand. Job 4: Drill Intermediate/Production Hole Hazards and Contingencies >- One fault crossing is planned in this intermediate hole section of NWE 4-01. As planned, the well bore will encounter the fault at - 3100' MD / 2594' TVD, approximately 350' MD below the surface shoe. The estimated throw of the fault is approximately 25' downward to the West. The well will be -540 when crossing the fault. Lost circulation is considered to be a minor risk. Off-~t well L-117 cut this same fault within the Ugnu formation and had no losses with a 10.3 ppg mud. Nevertheless, consult the Lost Circulation Decision Tree regarding LCM treatments and procedures. NEW 4-01 Permit to Drill 2/27/02 Page 8 ') ) ~ The Top Schrader OA target polygon has been sized to avoid a fault to the southwest of the well bore. Therefore, consider the southwest side of the polygon as a hard-line and don't be short. ~ Minor cuttings gas and gas cut mud was encountered within the Ugnu and Schrader interval on the nearest off-set well NWE 2-01. The well was drilled with 9.3 to 9.5 ppg mud through the Ugnu and Schrader intervals without any problems, nevertheless monitor for any signs of overpressure. ~ Differential sticking will be a problem if the drill string is left stationary for an extended period of time across the long permeable sections of the Ugnu and Schrader Sands. Minimize the time the pipe is left stationary. ~ For adequate hole cleaning flow rates should be maintained in the 575 gpm range particularly while drilling with higher ROP's (300'/hr) through the SV and Ugnu intervals. ~ KICK TOLERANCE: The Schrader Bluff reservoir pressure is anticipated to range from 8.6 to 9.0 ppg within the yarious sand intervals. The worst case kick tolerance for the 8%" open hole section would be 25.7 bbls assuming a kick from the Schrader Ma sand at -5041' MD 1 3749' TVD. This is a worst case scenario based on a 9.3 ppg pore pressure gradient at the Schrader Ma depth, a fracture gradient of 11.5 ppg at the 9-5/8" shoe, gauge hole, and 9.5 ppg mud in the hole. An accurate LOT will be required as well as heightened awareness of kick detection. Contact Anchorage personnel if LOT is less than 11.5 ppg. ~ A heightened awareness of kick detection, pre-job planning and trip tank calibration will be essential while drilling and tripping. ~ Drilling Close Approach: All wells pass BP Close Approach guidelines. Job 5: Loa Intermediate/Production Hole Hazards and Contingencies ~ The base plan consists of two wireline runs and one DP conveyed run. If the initial wireline attempt with the PEX 1 Sonic or the SWC's is unsuccessful at getting down, these tools will be DP conveyed. ~ If logging time is excessive or hole conditions dictate, perform an intermediate clean out run between logging runs. Job 6: Install 7" Intermediate/Production Casina Hazards and Contingencies ~ The decision to run 7" casing and continue with the forward operations will be based upon the open hole logging results and the amount of net pay encountered. If the well is not completed, the open hole and 9-"- 5/8" surface casing will be plugged and abandoned as per the AOGCC requirements. ~ Differential sticking is a concern across the Ugnu and West Sak sand intervals. Communicate individual responsibilities to all members of rig team and review connection / tripping practices to minimize the time the pipe is left stationary. ~ Verify the floats are holding prior to continuing operations. If floats are not holding, hold pressure and wait on cement. Job 7: Drill 6-1/8" Horizontal Production Hole Hazards and Contingencies ~ One fault crossing is planned in this horizontal hole section of NWE 4-01. As planned, the well bore will encounter the fault in the upper Colville at -7030' MD 1 4703' TVD (approximately 400' MD below the 7" shoe). The estimated throw of the fault is approximately 25' and the well will be -102° when crossing the fault. Lost circulation is considered to be a minor risk because of the location of the crossing (high clay NEW 4-01 Permit to Drill 2/27/02 Page 9 ') ') content of Colville) and low mud weight. Nevertheless, consult the Lost Circulation Decision Tree regarding LCM treatments and procedures. ~ Based upon logging results and the amount of net pay encountered in the 8%" section, the wellbore profile in this horizontal section may be slightly modified. The contingency plan will be along the same trajectory, however may be at a steeper angle to hit the top Schrader OA closer (500 to 1000') to the first penetration. ~ Based upon the reservoir pressures measured with the open hole MDT, the mud weight used to drill this section may be adjusted to avoid any unnecessary overbalance. ~ KICK TOLERANCE: The kick tolerance for the 6-1/8" open hole section would be an infinite influx assuming a kick from the Schrader. This is a worst case scenario based on a 9.1 ppg pore pressure gradient, a fracture gradient of 10.5 ppg at the 7" shoe, and 9.3 ppg mud in the hole. ~ Drilling Close Approach: All wells pass BP Close Approach guidelines. Job 9: Install 4Y2" Horizontal Production Liner Hazards and Contingencies ~ Differential sticking could be a problem. Minimize the time the pipe is left stationary while running the liner. ~ Ensure the liner top packer is set prior to POOH. This may require going through the setting process twice. Slack off with rotation to the maximum allowable down weight, as per Baker representative.

The diesel flash point is 100° F. Diesel vapor pressure is - 0.1 psia at 100° F. Job 13: ND/NU/Release Ria Hazards and Contingencies ~ 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.

" across IS In erva . ,~l'(("\ to!.-" NWE 04-01 presents an excellent opportunity to gain shallow logs across hydrate-bearing zones. Hydrates are expected from base of permafrost (2085' MD, 1860' TVDSS) to at ./ least the top of the SV1 zone (~2574', ~2200' TVDSS). Four offset wells show significant amounts of gas beginning between at subsea depths of -1700 to -1925 feet that are due to either free gas trapped at the base of permafrost or hydrates. Three offset wells have EWR, DIL and Laterologs across this interval, but the nearest porosity 102S are 3 miles SE in L-1 06 (the distance from ih Ave to International Airport Road), and about 3 miles to the NW in Milne Point Unit S-15. Obtaining a complete suite of logs across this interval will provide valuable data for determining the presence and extent of gas hydrates in this area. /"...----'- -" /ó~ '3-S~ ) ) H 205534 DATE 02/15/02 ~CK NO. 00205534 DATE INVOICE / CREDIT MEMO 021302 CK021302C PYMT COMMENTS: HANDL I NG I NST: DESCRIPTION GROSS VENDOR DISCOUNT ALASKAOILA NET 100. 00 00 100.00 Per~it to Drill Fee S/H - Sandra Stenman X4750 RECEiVED M~\¡~ (; J 2 ~w6 4øOl Alaska Oil & Gas Coos.
