Dear Mr. Rixse, Enclosed please find a copy of a spreadsheet with a list of Prudhoe Bay wells that were topped-off with cement, corrosion inhibitor in the surface casing by conductor annulus through 02/09/2024. Cement top-offs are executed as needed to mitigate the void space left at surface by minor cement fallback during the primary surface casing by conductor cement job. The remaining void space between the top of the cement and the top of the conductor is filled with a heavier than water corrosion inhibitor to reduce the risk of external surface casing corrosion. The attached spreadsheets include the well names, API and PTD numbers, treatment dates and volumes. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10-404 Report of Sundry Operations. If you have any additional questions, please contact me at 564-4891 or oliver.sternicki@hilcorp.com.

Operation Procedure 1) Slickline: Prepare well for HAW sand-back & fracs: a) Dummy-off GLMs. i) An HOT of the tubing may be necessary to get slickline tool action at higher angles. b) Set sidepocket memory gauge in GLM #1 @ 6058' MD (57°). i) Program gauge with high daytime and Iow nightime capture rate. Period Sample Frequency Number of Samples (1) 7 AM - 10 PM 12 seconds 4500 (2) 10 PM - 7AM 1 minute 540 The gauge should hold 2 weeks of data (75,000 lines) at this capture rate. (3) After this data gathering period, have the gauge go into the hibernate mode, with a pressure trigger to activate for one more day of high sample rate. c) MIT IA to 4000 psig. 2) Fullbore Sand-Back of HAW: a) Sand-back with to_+7530' MD: i) The sand-back top needs to be above the top of the liner hanger (7568') and below the upcoming perfs (78° OBd heel 7490-7492'). The liner hanger has 5 ina of flow area and does not have a packer, thus this circulation path must be blocked for the frac. The leak-off rate needs to be < 0.5 BPM at 1500 psig wellhead surface (dead string side), so that leak-off does not compromise the upcoming frac. The well must be able to hold 600 psig (acceptable if continuous pumping) to allow use of the Schlumberger CTU e-Fire select fire perforating system. ii) Bullhead in 5 Bbl Schlumberger Protectozone viscous pill (details in spreadsheet) at 3 - 5 BPM. This cross-linked HEC pill will remain in place until broken with HCI. It should provide a pillow to land the slurry pill on. iii) Bullhead in 2800 lbs of sand in a slurry pill of 14 Bbls of 6 ppg sand / 40 ppMg HEC gel (details in spreadsheet) at 3 - 5 BPM. A mixture of 20-40 River Sand and 100 Mesh Sand is recommended to form both an interlocking tight bridge and also to keep the sand-back material from rolling downhill. iv) Displace the leading edge of the slurry pill to 1 Bbl below the liner top at 7568' with 5 Bbls of 40 ppMg HEC gel, followed by 50 Bbls of seawater, followed by 26 Bbls of 60/40 Methanol at 3 - 5 BPM, reducing the rate 1 v) vii) Shut ~( .... n for 15 minutes to let the sand form (' 'idge. Slowly pump on and hesitate to pack the sand into a bridge. The maximum incremental working volume of fluid is only 12 Bbls before the desired sandback depth of _+7530' is reached. If it becomes necessary to lay in another sand slurry pill to get a bridge to hold, then it is recommended to leave the existing sand pill and viscous pill in place and attempt to spot the next sand pill with CTU. Pressure test sandback to 1500 psig wellhead surface (dead string side). A leak-off rate of < 0.5 BPM is acceptable. 3) CTU: Dress-off Sand-back & perf OBd (heel): a) Dress-off sandback plug to _+7530' MD. If a fill clean-out is required, then circulate clean to _+7530' and perform another leak-off test. If the leak-off rate is greater than 0.5 BPM: i) then pull to safety, close in, and pump 1 Bbl of fluid at 1/2 BPM and hestitate. Repeat up to the point that there is still 1 Bbl of the slurry pill from step 2)a)iii above the liner top packer. If the leak rate is still greater than 0.5 BPM; (1) then circulate in a small 100 mesh sand pill, close in and hesitate squeeze until a bridge is formed. b) Perf OBd sand from 7490 - 7492' ELM (twice, yielding 12 spf, spreadsheet attached). i) Recommend Schlumberger e-Fire system (+$3500). Allows two separate select fire gun runs on a single CTU trip. First gun fires on fail safe pressure telemetry. Second gun fires with ball drop. ii) Two runs: 60° phasing 6 JSPF, 2-1/2" 35B UP charges, random orientation. iii) 5 of 6 holes with > 8:1 perf:prop ratio, ie 0.33" perfs > 8 x 0.0394" prop diameter. iv) HAW necessitates very short perf section (2') to initiate a single frac. Friction issue: (1) 12 SPF: 18 BPM / 25 perfs = 0.7 BPM/perf. dPperf friction = 150 psi (negligible). (2) 6 SPF: 18 BPM / 13 perfs = 1.4 BPM/perf. dPperf friction = 400 psi (tolerable). (3) 2 SPF: 18 BPM / 4 perfs = 1.4 BPM/perf. dPperf friction - 1000 psi (significant). 4) OBd Fracture Treatment: a) Load frac tanks with - 100°F 2% KCI water; - 1600 bbls are required (excluding tank bottoms). b) RU the tree-saver/isolation tool for 3 1/2" 9.3 #/ft tubing (verify from rig tubing tally that a joint of 4-1/2" tubing was not run on top). PT backside and maintain 3500 psi throughout treatment (set inner annulus pop-off at 4000 psi). Note, this well has a conventional completion with anchored packer and should withstand treating pressures up to 8500 psi. Pressure test the treating lines to 8000 psi. Set pressure relief valve to 7500 psi, and set pump trips to 7000 psi. This well is expected to treat at ___4100psi (including 1000 psi near well friction) and require 1800 HHP. It is recommended that 3 pumps be on location (1 backup). c) Breaker Tests will be performed on fluids Prior to frac. The breaker schedule will be designed to ensure fluid stability at end of pump time with complete break wi" '~ one hour of shutdown. A minimum '00 cp @ 100 sec-~ is required au shutdown. d) Perform on-site pre-job QA/QC tests and complete BP form. e) Begin pumping Data frac, initial rate will be 5 bpm while displacing wellbore fluid, after displacing Data frac fluid to within a few barrels of top perf, increase pump rate to 18 bpm to displace Data frac. Shutdown for ISIP, monitor for closure time, calculate efficiency and adjust frac schedule as necessary (pad size, fluid loss additive, etc). f) Additional diagnostic tests may be performed after Data frac analysis. Consult with engineer before proceeding with frac. g) Re-establish injection, when add rates are lined out, start counting PAD. Pump pad at 5 BPM and early sand stages at 10 BPM until pad on perfs, then increase rate to 18 BPM. Pump the proppant schedule as detailed in the attached pump schedule. Flush with linear fluid and diesel for freeze protection. i) Underflush by 4 Bbls to provide perf sandback coverage. The top of the slurry should be between the existing OBd perfs (7490-7492') and the upcoming OBc perfs (7300-7302'). The sand will settle to the Iow side of the hole in the 70° hole section. h) Shut-in for ISIP, monitor for 15 minutes. i) Bleed off excess annulus pressure. Rig down service company. 5) CTU prepare for OBc frac a) Dress-off sandback plug to ___7400' MD. If a fill clean-out is required, then circulate clean to __.7400' and perform a leak-off test. If the leak-off rate is greater than 0.5 BPM: i) then, pull to safety, close in, and pump 1 Bbl of fluid at Y2 BPM and hestitate. Repeat up to 3 Bbls (4 Bbl frac underflush volume above perfs. If the leak rate is still greater than 0.5 BPM; (1) then circulate in a small mixed 20-40 and 100 mesh sand pill, close in and hesitate squeeze until a bridge is formed. b) Perf OBc sand from 7300 - 7302' ELM (twice, yielding 12 spf, spreadsheet attached). i) Recommend Schlumberger e-Fire system (+$3500). Allows two separate select fire gun runs on a single CTU trip. First gun fires on fail safe pressure telemetry. Second gun fires with ball drop. ii) Two runs: 60° phasing 6 JSPF, 2-1/2" 35B UP charges, random orientation. iii) 5 of 6 holes with > 8:1 perf:prop ratio, ie 0.33" perfs > 8 x 0.0394" prop diameter. iv) HAW necessitates very short perf section (2') to initiate a single frac.

The sand will settle to the Iow side of the 65° hole section. h) Shut-in for ISIP, monitor for 15 minutes. i) Bleed off excess annulus pressure. Rig down service company. 7) CTU prepare for OBa frac a) Dress-off sandback plug to +_7200' MD. If a fill clean-out is required, then circulate clean to +_7200' and perform another leak-off test. If the leak-off rate is greater than 0.5 BPM: i) then, pull to safety, close in, and pump 1 Bbl of fluid at Y2 BPM and hestitate. Repeat up to 4 Bbls (5 Bbl frac underflush volume above perfs. If the leak rate is still greater than 0.5 BPM; (1) then circulate in a small mixed 20-40 and 100 mesh sand pill, close in and hesitate squeeze until a bridge is formed. b) Perf OBa sand from 7090 - 7092' ELM (twice, yielding 12 spf, spreadsheet attached). i) Recommend Schlumberger e-Fire system (+$3500). Allows two separate select fire gun runs on a single CTU trip. First gun fires on fail safe pressure telemetry. Second gun fires with ball drop. ii) Two runs: 60° phasing 6 JSPF, 2-1/2" 35B UP charges, random orientation. iii) 5 of 6 holes with > 8:1 perf:prop ratio, ie 0.33" perfs > 8 x 0.0394" prop diameter. iv) HAW necessitates very short perf section (2') to initiate a single frac. Friction issue: (1) 1 'PF: 18 BPM / 25 perfs = 0.7 BPM/pe IPperf friction = 150 psi (negligible). (2) 6 SPF: 18 BPM / 13 perfs = 1.4 BPM/perf. dPperf friction = 400 psi (tolerable). (3) 2 SPF: 18 BPM / 4 perfs = 1.4 BPM/perf. dPperf friction = 1000 psi (significant). 8) OBa Fracture Treatment a) Load frac tanks with - 100°F 2% KCI water; - 1600 bbls are required (excluding tank bottoms). b) RU the tree-saver/isolation tool for 3 Y2" 9.3 #/ft tubing (verify from rig tubing tally that a joint of 4-1/2" tubing was not run on top). PT backside and maintain 3500 psi throughout treatment (set inner annulus pop-off at 4000 psi). Note, this well has a conventional completion with anchored packer and should withstand treating pressures up to 8500 psi. Pressure test the treating lines to 8000 psi. Set pressure relief valve to 7500 psi, and set pump trips to 7000 psi. This well is expected to treat at _+4100psi (including 1000 psi near well friction) and require 1800 HHP. It is recommended that 3 pumps be on location (1 backup). c) Breaker Tests will be performed on fluids prior to frac. The breaker schedule will be designed to ensure fluid stability at end of pump time with complete break with-in one hour of shutdown. A minimum of 100 cp @ 100 sec-1 is required at shutdown. d) Perform on-site pre-job QA/QC tests and complete BP form. e) Begin pumping Data frac, initial rate will be 5 bpm while displacing wellbore fluid, after displacing Data frac fluid to within a few barrels of top perf, increase pump rate to 18 bpm to displace Data frac. Shutdown for ISIP, monitor for closure time, calculate efficiency and adjust frac schedule as necessary (pad size, fluid loss additive, etc). f) Additional diagnostic tests may be performed after Data frac analysis. Consult with engineer before proceeding with frac. g) Re-establish injection, when add rates are lined out, start counting PAD. Pump pad at 5 BPM and early sand stages at 10 BPM until pad on perfs, then increase rate to 18 BPM. Pump the proppant schedule as detailed in the attached pump schedule. Flush with linear fluid and diesel for freeze protection. i) Underflush by 4 Bbls to prevent overflushing the slurry past the perfs. h) Shut-in for ISIP, monitor for 15 minutes. i) Bleed off excess annulus pressure. Rig down service company. 9) Fill Clean-Out a) Perform CTU fill clean-out and acid wash to - 8900' MD (last tag) or bottom of slotted liner (9040' MD): i) If possible, set GLVs to perform an GLT under-balanced FCO. ii) If an under-balanced FCO is not possible, then use filtered seawater and HEC gel sweeps to clean out. To minimize near wellbore damage, HEC gel sweeps are requested. Biozan gel does not break well at Schrader Bluff formation temperature of 100°F and may cause significant near wellbore damage. Have lab determine HEC gel & breaker loading for mix water at 100°F and desired working time. iii) Expect to encounter sand-back plugs at - 7200', -7400', and -7300'. b) Jet and ci( .... 'ate out 1000 gals of 7-1/2% HCL thru" "~ the 5 Bbl Protectozone viscous pill, which should be at - 7630- 7960' MD. I'his cross-linked HEC viscous pill is non-damaging to the reservoir, but must be broken with HCI. c) Clean-out to - 8900' MD (last tag) or bottom of slotted liner (9040' MD). Circulate clean. d) Freeze protect to 2500' with neat methanol. 10) Prep for Production a) Slickline retrieve SPMG in STA #1 GLM, at 6058' MD. b) It has proven beneficial in preventing hydrates to circulate 170° F hot oil around the IA and tubing shortly prior to POP'g. Thus, when the well is kicked-off, warm fluid is being flowed down the annulus and up the tubing. The gas lift engineer will need to confirm a design that will allow valve opening at 150° F kick-off and valve closing at 40° F operating conditions. If a gas lift design cannot be arrived at to accommodate the HOT, then drop the HOT and instead circulate 20-30 Bbls of Methanol into the IA to provide as a spear ahead of the displacing gas lift. If pumping liquid into the IA and down through a gas lift valve, then limit the surface injection pressure to 1000 psig (~ 1 BPM) to prevent damage to the gas lift valves. c) Set GLV design to lift from bottom. 11) Frac Flowback a) Rig up flowback test separator. b) Schrader wells tend to hydrate-off, especially when unloading cold fluids. Treat gas lift with methanol to prevent freezing. c) Attempt to quantify returned proppant to tank. This will help determine proper flowback procedures. d) Unload well with 0.5 MMSCFGPD. Once the IA volume has been recovered, maintain the production rate at 300 BPD (via the choke). e) Conduct 4 hour well tests. If after 12 hours, solids are <0.1%, then increase GLT to 1 MMSCFGPD and open choke until rate is 600 BPD. f) Conduct 4 hour well tests. If after 12 hours, solids are <0.1%, then increase GLT to 1.5 MMSCFGPD and set choke at full open. g) Do not surge well to flow-back proppant. Surging could cause formation failure and sand production. h) Continue producing to the flow-back separator until the frac gel load has been recovered or the watercut < 10% and the solids production is less than 0.1%. 12) Put well on production immediately. To prevent hydrate formation, do not leave the well shut-in, unless the Pad Operator instructs to shut-in. Don Schmohr TREE = 4-1/16" ClVV WELLHEAD= FMC ACTUATOR= KB. ELEV = 81.3' BF.

The Division approved this request in its letter of F~bruary 21 and has since extended its approval until September 1,2001. On Friday, August 31, ~001, BP submitted the final documents relative to the Polaris PA along with a request for continued Tract Operations for the Polaris wells to allow for continued production until such time as .,[the Polaris PA is approved by the Division, BP's Tract Operations request of February 20 s~ggested that production from the W-201 well would potentially be from both ADL 047451 a~d ADL 47452 and that we would propose an allocation between these two leases when the 'well was opened to production. This letter incorrectly identified the leases from which production might be attributed, The correct leases should have been ADL 047451 and ADL 028263~1. The W-201 well has been drilled and is now ope~ tO production. The well bottomhole loea,tion was very near the lease line between ADL 047451 and ADL 028263-1; however, it has since been plugged back to a point substantially away f.rom the lease line. All production for this well will be allocated to lease ADL 028263-1, A pla~ is attached which depicts the well trajectory, bottomhole location, plug back location, and the 16, use boundaries, I I apologize for any confusion that the original request may have caused and I look forward to your favorable reply to our August 31~ request ~ ' ' a~d the ulttmate approval of the Polaris you need any additional information, please call me at 564-5727, Best regards, Senior Commercial Analyst BP Exploration (Alaska) Inc.

P.O. Box 196612 Anchorage, AK 99519-6612 Subject: Application for Extension of Pilot Production Operations Well W-200; and Initial Production Operations at W-201, Prudhoe Bay Unit - Polaris Accumulation (Schrader Bluff Formation), ADL-28263, 047451, and 047452. File: Prudhoe Bay Field - Polaris Pool Dear Mr. Beuhler: The AOGCC has received an application from BP Exploration (Alaska) Inc. ("BP") to extend pilot production operations at the Polaris prospect, Prudhoe Bay Unit, at Well W-200 through August 31, 2001 and to initiate pilot production operations at Well W-201. The request is based on the need for additional information to evaluate primary development and establish a depletion plan. On February 22, 2001, BP provided additional information to Jack Hartz, AOGCC Sr. Reservoir Engineer, regarding primary' production and the anticipated pressure response during the extended production period. The AOGCC approved the original request for a waiver of the GOR limitations of 20 AAC 25.240 for production operations on W-200. The waiver of the GOR limitations is necessary to continue tract and production operations at W-200, and the initial tract and production operations at W-201. Prior production reporting and allocation procedures are still applicable. Production should be reported to the Polaris Undefined Pool, number 640160. Your commitment to gather pressure data and maintain reservoir pressure aboVe bubble point will ensure reservoir energy is not diminished unnecessarily. We anticipate you will .keep the Commission informed about any significant developments. Therefore the Commission approves an extension of the Gas-Oil ratio variance through the end of August 2001 for well W-200 and through February 28, 2002 for W-201, conditioned on reservoir pressure performance. AOGCC approval is coincident with any restrictions imposed by The Division of Oil & Gas on Tract or PA operations. PresSure data should be forwarded to the AOGCC after each survey, or pressure test. If there are any questions please contact Jack Hartz at 279-1433 ext. 232. Copy: Mark Myers, DOG D.E.

Reference RPs 4° "Drilling/Workover Close Proximity Surface and Subsurface Wells Procedure" Operational Specifics Job 2: Drillinq Surface Hole Hazards and Contingencies > No faults are expected to be penetrated by W-201 in the surface interval. The SV1 sand may contain gas hydrates, however, only two wells have encountered thus far in the W-pad development. Hydrate will be treated at surface with appropriate mud products. W-Pad does not have a history of over-pressure in the SV3/Cretaceous intervals from Produced water injection. Reference RPs Operational Specifics Job 3: Install surface Casinq Hazards and Contingencies ~ It is critical that cement is circulated to surface for well integrity. 175% excess cement through the permafrost zone (and 30% excess below the permafrost) is planned. As a contingency, a 9-5/8" port collar will be positioned at ___1000'MD to allow a secondary circulation as required. Reference RPs Operational Specifics RECEIVED MAR 0 7 ZOO1 Alaska Oil & Gas Cons. Commission Anchorage Job 4: Drillinq Intermediate Hole Hazards and Contingencies ~ W-201 is not expected to penetrate any faults in either the reservoir or tangent sections. It is important that the planned well trajectory for W-201 be maintained in the Ugnu W-201 Permit to Drill Final Page 6 section of the well, as W-201 W.P. #1 passes 600' north of a small offset (<20') fault. W-201 also passes -700' north of the tip out of a second small offset fault (<20') in the Schrader Bluff OA Sand interval. The surface casing point is chosen just below the SV3 sands, leaving the SV1 exposed for the 8-3/4" hole. The intermediate TD is above the HRZ, (Schrader OBd), a lower mud weight will be require, thus minimizing the risk of differential sticking across the SV1. The kick tolerance for the 8 3A" open hole section would be 107 bbls assuming an influx from the Schrader interval at -7749' MD. This is a worst case scenario based on a 8.6 ppg pore pressure gradient, a fracture gradient of 12.5 ppg at the surface casing shoe, and 10.5 ppg mud in the hole. Rig will perform LOT after drilling 20ft of new formation.

For this reason the 7" casing will be cemented to 500' above the Ugnu 4A sand (the uppermost significant hydrocarbon). After freeze protecting the 7" x 9-5/8" casing annulus with dead crude, the hydrostatic pressure alone will be less than the formation pressure. Ensure a double-barrier at the surface on the annulus exists until the cement has set up for at least 12 hours. Expect trapped annulus pressure after pumping the dead crude.

Maintain mud properties, Iow MBT and fluid loss, while drilling the production interval. Avoid leaving the drilling string stationary for extended periods of time. No planned fault crossings in the production interval. The kick tolerance for the 7" shoe would be an infinite influx (annular volume) assuming an influx at section TD of 12,811' MD. This is a worst case scenario based on a 8.6 ppg pore pressure, a minimum fracture gradient of 9.5 ppg at the 7" casing shoe, and 9.1 ppg mud in the hole.
