Huber, Sr. Date: 2023.10.05 08:59:12 -08'00'10/05/23 RBDMS JSB 100523 To: Alaska Oil & Gas Conservation Commission From: Ryan Ciolkosz Drilling Engineer Date: Re: PBU 01-28A Sundry Request Sundry approval is requested to set a whipstock and mill the window in 01-28A as part of the drilling and completion of the proposed 01-28B CTD lateral. Proposed plan for 01-28B Producer: Prior to drilling activities, slickline will pull the LTP and screening will be conducted to drift and caliper for whipstock and MIT. E-line will set a 3-1/4" packer whipstock. Coil will mill window pre-rig. If unable to set the whipstock or milling the window, for scheduling reasons, the rig will perform that work. A coil tubing drilling sidetrack will be drilled with the Nabors CDR2 rig. The rig will move in, test BOPE and kill the well. If unable to set whipstock pre-rig, the rig will set the 3-1/4" packer whipstock. A single string 2.74" window + 10' of formation will be milled. The well will kick off drilling in the Ivishak Zone 4. The lateral will continue in Zone 4 and 3 to TD. The proposed sidetrack will be completed with a 2-3/8” 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 Ivishak perfs. The following describes the work planned. A wellbore schematic of the current well and proposed sidetrack is attached for reference. This Sundry covers plugging the existing perforations via the packer whipstock and liner cement job or liner top packer, if the liner lap pressure test fails (alternate plug placement per 20 AAC 25.112(i)). Pre-Rig Work: (Estimated to start in October 15th, 2023)Reference 01-28B Sundry submitted in concert with this request for full details. 1. Slickline: Pull LTP. Caliper Whipstock Setting location. Dummy WS drift. Dummy GLVs 2. E-Line: Set Whipstock 3. Fullbore: MIT-IA and MIT-T to 2500 psi 4. Coil: Mill Window (if window not possible, mill with rig) 5. VS: Pre-CTD Tree Work 6. Ops: Remove wellhouse and level pad. Rig Work: (Estimated to start in December 11, 2023) 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2,415 psi). a. Give AOGCC 24hr notice prior to BOPE test b. Test against swab and master valves (No TWC) c. Load pits with drilling fluid d. Open well and ensure zero pressure. Kill well. 2. Mill 2.74” Window. (If not done pre-rig) a. Top of window (whipstock pinch point) at 9988' MD. b. Single string exit (out of 3-1/4" liner) plus 10' of rathole. 3. Drill build section: 3.25" OH, ~257' (42 deg DLS planned) and production lateral: 3.25" OH, ~1881' (12 deg DLS planned). a. Drill with a constant bottom hole pressure for entire sidetrack b. Pressure deployment will be utilized c. Lay in completion/kill weight fluid in preparation for liner run after TD and on the last trip out of hole d. No flow test prior to laying down drilling BHA. Confirm well is dead prior to picking up liner. Sundry 323-532 PTD 223-0XX 4. Run 2-3/8” 13Cr liner. Pump primary cement job: 18 bbls, 15.3 ppg Class G, TOC at TOL*. a. Have 2" safety joint with TIW valve ready to be picked up while running liner b. Swap well over to KCl d. Freeze protect well to a min 2,200' TVDss e. RDMO * Approved alternate plug placement per 20 AAC 25.112(i) Post Rig Work: 1. Valve Shop: Valve & tree work 2. Slickline: SBHPS, set LTP* (if necessary). Set live GLVs. 3. Service Coil: Post rig perforate (~300’) and RPM. The sundry and permit to drill will be posted in the Operations Cabin of the unit during the window milling operation. Window Milling Fluids Program: x A min EMW of 8.4 ppg KCL. KCl will be used as the primary working fluid and viscous gel sweeps will be used as necessary to keep the hole clean. x The well will be freeze protected with a non-freezable fluid (typically a 60/40 methanol/water mixture) prior to service coil’s departure. x Additionally, all BHA’s will be lubricated and there is no plan to “open hole” a BHA. Disposal: x All Class l & II non-hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS 4. x Fluids >1% hydrocarbons or flammables must go to GNI. x Fluids >15% solids by volume must go to GNI. Hole Size: x The window and 10’ of formation will be milled/drilled with a 2.74” OD mill. Well Control: x BOP diagram is attached. x AOGCC will be given at least 24-hour notice prior to performing a BOPE function pressure test so that a representative of the commission can witness the test. x Pipe rams, blind rams, CT pack off, and choke manifold will be pressure tested to 250 psi and at least 3,500 psi. x BOPE test results will be recorded in our daily reporting system (Alaska Wells Group Reporting System) and will provide the results to the commission in an approved format within five days of test completion. x BOPE tests will be performed upon arrival (prior to first entry into the well) and at 7 days intervals thereafter. x 10 AAC 25.036 c.4.C requires that a BOPE assembly must include “a firewall to shield accumulators and primary controls”. A variance is requested based on the result of the joint hazop with the AOGCC. For our operation, the primary controls for the BOPE are located in the Operations Cabin of the Coiled Tubing Unit, and the accumulators are located on the backside of the Operations Cabin (opposite side from the well). These are approximately 70' from the well. Hazards: x DS 01 is an H2S pad. H2S reading on 01-28A: 24 ppm on 01/11/2020. x Max H2S recorded on DS 01: 375 ppm. x 3 fault crossings expected. x Medium lost circulation risk. Reservoir Pressure: x The reservoir pressure is expected to be 3294.72 psi at 8800 TVD. (7.2 ppg equivalent). x Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,415 psi.

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.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. 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 require any additional information, please contact me or my alternate, Gerald Murphy, at 659 -5102. Sincerely, Mehreen Vazir BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.
