Proposed plan: Prior to drilling activities, screening will be conducted to drift for whipstock and MIT. E-line will set a 4-1/2" packer whipstock. Coil will mill window pre-rig. If unable to set the whipstock or mill the window, for scheduling reasons, the rig will perform that work. See H-02C PTD request for complete drilling details - A coil tubing drilling sidetrack will be drilled with the Nabors CDR2 or CDR3 rig. The rig will move in, test BOPE and kill the well. If unable to set whipstock pre-rig, the rig will set the whipstock. A single string 3.80" window will be milled (if not already milled pre-rig). The well will kick off drilling in the Sag and lands in Ivishak Zone 4. The lateral will continue in Zone 4 to TD. The proposed sidetrack will be completed with a 3-1/2"x3-1/4"x2-7/8” 13Cr solid liner, cemented in place and selectively perforated post rig (will be perforated with rig if unable to post rig). This completion will completely isolate and abandon the parent Prudhoe Pool perforations. 20 AAC 25.112(i) Variance Request: Hilcorp requests to plug the existing perforations via the liner cement job, packer whipstock and/or liner top packer, if the liner lap pressure test fails as an alternate plug placement. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the current wellbore and proposed sidetrack is attached for reference. Pre-Rig Work: (Estimated to start in January 2025) 1. Slickline : Dummy WS drift 2. E-Line : Set 4-1/2" Packer Whipstock at 9,865’ MD at 30 degrees LOHS 3. Fullbore : MIT-IA and/or MIT-T to 3,500 psi 4. Coil : Mill Window (if window not possible, mill with rig). See attached procedure. 5. Valve Shop : Pre-CTD Tree Work 6. Operations : Remove wellhouse and level pad. Rig Work: x Reference H-02C PTD submitted in concert with this request for full details. 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2,432 psi). Give AOGCC 24hr notice prior to BOPE test. 2. Mill 3.80” Window (if not done pre-rig). 3. Drill build section: 4.25" OH, ~419' (24 deg DLS planned). 4. Drill production lateral: 4.25" OH, ~1,383' (12 deg DLS planned). Swap to KWF for liner. 5. Run 3-1/2” x 3-1/4” x 2-7/8” 13Cr solid liner (swap to VBRs and test prior to running liner) 6. Pump primary cement job: 23 bbls, 14.8 ppg Class G, 1.24 (ft3/sk), TOC at TOL*. 7. Only if not able to do with service coil extended perf post rig – Perforate Liner 8. Freeze protect well to a min 2,200' TVD. 9.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of "Suspended." Step Task Responsible 1 The initial reviewer will check to ensure that the "Plug for Redrill" box in the upper left corner of Form 10-403 is checked. If the "Abandon" or "Suspend" boxes are also checked, cross out that erroneous entry and initial it on the Form 10-403. Geologist 2 If the “Abandon” box is checked in Box 15 (Well Status after proposed work) the initial reviewer will cross out that checkbox and instead, check the "Suspended" box and initial those changes. Geologist The drilling engineer will serve as quality control for steps 1 and 2. Petroleum Engineer (QC) 3 When the RA2 receives a Form 10-403 with a check in the "Plug for Redrill" box, they will enter the Typ_Work code "IPBRD" into the History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." Research Analyst 2 4 When the RA2 receives Form 10-407, they will check the History tab in RBDMS for the IPBRD code. If IPBRD is present and there is no evidence that a subsequent re-drill has been completed, the RA2 will assign a status of SUSPENDED to the well bore in RBDMS. The RA2 will update the status on the 10-407 form to SUSPENDED, and date and initial this change. If the RA2 does not see the "Intent: Plug for Redrill" comment or code, they will enter the status listed on the Form 10-407 into RBDMS. Research Analyst 2 5 When the Form 10-407 for the redrill is received, the RA2 will change the original well's status from SUSPENDED to ABANDONED. Research Analyst 2 6 The first week of every January and July, the RA2 and a Geologist or Reservoir Engineer will check the "Well by Type Work Outstanding" user query in RBDMS to ensure that all Plug for Redrill sundried wells have been updated to reflect current status. At this same time, they will also review the list of suspended wells for accuracy and assign expiration dates as needed.

Guy Schwartz Senior Petroleum Engineer AOGCC 793 -1226 (office) 444 - 3433 (cell) From: Rixse, Mel G mailto:Mel.Rixse @b .com P l Sent: Wednesday, July 14, 2010 5:28 PM To: Tirpack, Robert B; Schwartz, Guy L (DOA) Subject: H -02B 14 -July -2010 Doyon 14 Wellhead and Summary Guy, Here is a description of events on H -02B which lead to our phone conversations last night. 1. While drilling 8 -1/2" intermediate hole, at least 2 faults were crossed above the HRZ that created a fluid loss zone. The first fault was crossed at 7062' MD. The second fault was crossed at 7880' MD. The first fault was re squeezing healed with 40 ppb LCM pill. The second fault had significant losses, >60%, which required a lost ill with a new M-I product pill called EMI -1820. The losses were reduced to <5% while drilling the remainder of the intermediate hole section to a TD of 9815' MD which was approximately 5' into the top of the Sag. It should be noted that no hydrocarbon zones were exposed in the intermediate hole section, with the exception of the top 5' of transition into the very top of the Sag at TD . 2. A 7" intermediate string of casing was picked up and run to TD. While running the casing into the 8 -1/2" intermediate open hole, losses were observed, returns were reduced to zero when circulating, but the hole was kept full by circulating across the top of the well. Casing was run to TD, but no returns were observed while circulating to clean the hole for the cement job. No packing off was observed while circulating, it is apparent the loss zone at 7880' MD was taking the return fluid. 3. The 7" intermediate casing string was cemented with 38 bbls of 15.8 ppg class G cement. The plug was bumped as expected. Height of the cement, assuming gauge hole, would be approximately 1682' or 8,132' MD. Our normal conservative assumption is that hole is 40% bigger in volume, so the height of the cement is 1202' above the 7" casing shoe or 8612' MD (-7620' TVDSS) which is - 200' below the top of the Kingak. It should be noted that midway through the cement displacement slight fluid returns were observed and slowly increased to about 5% returns until the final plug bumped. The hole was kept full by circulating over the top of the well. 4. H -02B has been constructed with a Cameron Slip -Lock wellhead which requires setting the 7" casing in slips and hanging casing in the inner casing spool. The primary packoffs are energized by lock down screws in the inner casing spool. The secondary packoffs set in the base of the tubing spool. To set the slips on the 7" casing, the preferred method is to lift the BOPE equipment to set the slips and cut the 7" casing so it spaces out into the tubing spool for the secondary pack offs. This morning, the BOPE was lifted, the slips set, primary packoffs installed and energized, 7" casing cut and secondary packoffs were installed in the base of the tubing spool. Before that process began the well was observed for consistent fluid losses of -3 bph while waiting approximately 10 hours for cement to obtain 500 psi compressive strength. While the BOPE was lifted, the new OA was 7/20/2010 H -02B 14 -July -2010 Doyon 14 and Summary • Page 2 of 2 consistently checked and filled at -3 bph to assure overbalance of the well. The well was secured at -7 am and BOPE equipment is currently being installed and tested. 5. The 6 -1/8" production hole will be drilled after all BOPE equipment is tested. I sincerely appreciate your oversight during the late hours of the evening yesterday. If you need anything more, please let me know.

Excess volume should have been 22 bbls with 108 bbls being the annular volume from the ES cementer to surface. After pumping the cement and bumping plugs, no cement returns were seen at surface. Upon investigation by the cementing crew it was determined that - 105 bbls were pumped, not 130 bbls as requested. The cause was a recirculation valve left open on the tub on the cement unit. The calculated cement height below the well head is expected to be 50' below surface. As a mitigation measure, BP will pour 15.8 ppg cement down the annulus of the 9 -5/8" casing. The lead brine, ahead of the original cement job, is no greater than 8.8 ppg, so the brine should easily be displaced by the 15.8 ppg cement. Please let me know if you need additional explanation.

This barrier is redundant (above cement P&A and EZSV) and is not required to allow pressuring up to open the ES cementer for cementing the 9 -5/8" tie -back to surface. I would like to delete lines 13 and 30 from the Rig Operations section below. Additionally, I would like to reduce pressure testing of the 13 -3/8" IA from 2700 psi to 2500 psi. I am requesting this because of the age for the 13 -3/8" - K -55 - 47ppf casing. It was originally installed in 1971 so I would like to reduce the stress on this string. Please respond if you approve or call to discuss. Thank you.

Planned completion fluids 8.5 ppg Seawater / 6.8 ppg Diesel Other Request: Given rig floor height limitations, a MASP < 3000 psi, and the fact that the three ram drilling BOP configuration is preferred to a two ram configuration with a spool, BPXA will execute the provisions of 20 AAC 25.285 (f) (1) regarding the initial testing of the BOPE as follows when existing wellhead or testing equipment prevents the testing of the lowest set of pipe rams: That lowest set of rams will be tested at the earliest opportunity during path - forward de- completion work, i.e., after the completion has been pulled from the well. Safety concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the three -ram drilling BOP stack. H -02B Sidetrack Page 7 • • Well Control The intermediate and production hole sections will be drilled with well control equipment consisting of 5000 psi working pressure pipe rams(2), blind /shear rams, and annular preventer. This equipment is capable of handling maximum potential surface pressures. Based upon calculations below, BOP equipment will be tested to 3500 psi. Notes: 1.

(NOTE: This work will be completed under a separate AFE.) r H -02B Sidetrack Page 10 H - � Drilling Hazards and Contingers OST THIS NOTICE IN THE DOGHOUSE I. Well Control / Reservoir Pressures: Possible over - pressure ( -9.4 ppg) from the produced water injector in the Ugnu cretaceous sands. Probable area is +/- 4850' ss. A 9.3 ppg MW is recommended, but assure frequent flow checks as drilling approaches -4700' TVD. I1. Lost Circulation / Breathing: Highly probable while drilling & running intermediate casing from the Kingak @ 7400' through the Sag River Follow the RP guidelines for dealing with Lost Circulation problems when /if they occur. III. Kick Tolerance / Integrity Testing: Intermediate Section Kick Tolerance and Integrity Testing • Integrity Test - 8 -1/2" hole: LOT 20' - 50' from 9 -%" casing exit • Kick Tolerance: 25 bbl KT with a 9.3 ppg mud with a minimum 11.4 ppg LOT (NOTE: Need an 11.9 ppg FIT /LOT to satisfy ECD management requirements.) Production Section Kick Tolerance and Integrity Testing • Integrity Test - 6 -1/8" hole: FIT 20' - 50' from 7" shoe • Kick Tolerance: Calculated an Infinite KT with an 8.5 ppg mud with 9.0 ppg FIT /LOT (NOTE: Need a 11.0 ppg FIT /LOT to satisfy ECD management requirements.) IV. Stuck Pipe H -02A (2002 Sidetrack) Stuck 7" liner in the Kingak about 800 feet off bottom and could not be recovered or cemented in place. There will be some differential sticking tendencies across upper sands in the intermediate hole with the planned 10.6 ppg mud weight in the hole and in the production interval of the well while drilling with the 8.5 ppg plus FloPro, therefore, follow good drilling practices and good casing /liner running practices for both intervals of this well.

Schwartz, Guy L (DOA) From: Rixse, Mel G [Mel.Rixse @bp.com] Sent: Thursday, April 15, 2010 5:17 PM To: Schwartz, Guy L (DOA) Subject: RE: DS H -02B Sidetrack question ( PTD 210 -046) Guy, Regarding H -02B Wellhead and Surface Casing Work: In answer to your questions: 1) Why the new wellhead ? To replace an old wellhead and remove the exposure of IA pressures to very old K -55 grade intermediate casing. Discussion of Scope: The surface hole of H -02 was drilled in 1971. A string of 18 -5/8" K -55 surface casing was set and cemented. The intermediate casing string was a tapered string of 13 -3/8" K -55 (to 2271'MD) crossed over to 9- 5/8" N -80 to 8300' MD. The intermediate casing was cemented in 3 stages with the final stage providing 30 bbls returned to surface. In 1986 a 9 -5/8" tie -back string was run from 2271' to surface and cemented with 25 bbls ( -200') at the shoe. BP would like to remove the existing wellhead and replace it with a new "slip -lock" well head supported on a robust string of 9 -5/8" casing. The cemented 13 -3/8" X 18 -5/8" annulus (OOA) will be opened to the atmosphere. A new 9 -5/8" casing string will be run and will be fully cemented from 1853'MD to surface and will provide a durable support for the new slip -lock wellhead. The 'old' existing OA (external to the 9 -5/8" tie -back) will also be exposed to the atmosphere, but it will be fully cemented when the new 9 -5/8" tieback is run. After drilling the intermediate hole section, the new 7" x 9 -5/8" annulus will become the monitorable OA. 2) What is the condition of the current 13 3/8" x 18 5/8" annulus ? The 13 -3/8" x 18 -5/8" annulus is fully cemented. It does not pass an MIT. The OOA does build pressures of 400 -500 psi, if left shut -in. If opened, even when the well is POP, the measureable gas near the wellhead and within the well house is insignificant and almost immeasurable. The MIT -OA passes to 2400 psi. There should be no communication from the OA to the OOA. 3) Why are you pulling the existing 9 5/8" ? The existing 9 -5/8" tie -back casing is being cut, pulled, and replaced to provide mechanical support for the new slip -lock wellhead. The new slip -lock wellhead requires more length of 9 -5/8" casing above the existing cellar, then is currently available from the existing 9 -5/8" casing. I hope this provides an overview of the scope of the wellhead work we propose for H -02. Sincerely, Mel Rixse ODE From: Schwartz, Guy L (DOA) [ mailto:guy.schwartz ©alaska.gov] 4/16/2010 .
