SFD 2/15/2024 10-407 MGR08MAR24JLC 3/22/2024 To: Alaska Oil & Gas Conservation Commission From: Ryan Ciolkosz Drilling Engineer Date: February 13, 2024 Re: H-18 Sundry Request Sundry approval is requested to set a whipstock and abandon well H-18 as part of the drilling and completion of the proposed H-18A CTD lateral. Proposed plan for H-18A Producer: Prior to drilling activities, screening will be conducted to drift, caliper for whipstock and MIT. E-line will set the 4- 1/2" x 7" CTD whipstock. Service coil will cement squeeze the whipstock in place, mill XN-nipple and mill the 3.80' window. If unable to set the whipstock or milling the window, for scheduling reasons, the rig will perform that work. See H-18A Permit request for complete drilling details - 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 4-1/2" x 7" whipstock. A single string 3.80" window + 10' of formation will be milled. The well will kick off drilling in the Sag/Shublik and land in Ivishak Zone 2. The lateral will continue in Zone 2 to TD. The proposed sidetrack will be completed with a 3-1/2" x 3-1/4" x 2-7/8 13Cr solid liner, cemented in place and selectively perforated post rig (will be perferated with rig if unable to post rig). This completion will completely isolate and abandon the parent Ivishak perfs. This Sundry covers plugging the existing Ivishak perforations via the liner cement job or liner top packer, if the liner lap pressure test fails (alternate plug placement per 20 AAC 25.112(i)). The following describes the work planned. A wellbore schematic of the current well and proposed sidetrack is attached for reference. Pre-Rig Work: (Estimated to start in March 1st, 2024) Reference H-18 permit submitted in concert with this request for full details. 1. E-Line : Set 4-1/2 x 7 whipstock at 9031 MD and 0 deg RHOS. Pinch point = 9036 MD 2. Coil : Squeeze cement through WS, mill XN, mill window a. Mill Window (Mill with rig if needed) I. MIRU Service Coil Window Milling Surface Kit II. Give AOGCC 24hr notice prior to BOPE test III. Test BOPE to 3500 psi. MASP with gas (0.10 psi/ft) to surface is 2,506 psi IV. Mill 3.80 window plus 10 of rat hole V. Single string window exit out of 7 casing 3. Valve Shop : Pre-CTD Tree Work 4. Operations : Remove wellhouse and level pad. Rig Work: (Estimated to start in May 2024) 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2,506 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, ~1045' (22 deg DLS planned). 4. Drill production lateral: 4.25" OH, ~1500' (12 deg DLS planned). Swap to KWF if necessary. 5. Run 3-1/2 x 3-1/4 x 2-7/8 13Cr liner (swap to VBRs and test prior to running liner) 6. Pump primary cement job: 41 bbls, 15.3 ppg Class G, TOC at TOL*. 7. Freeze protect well to a min 2,200' TVD. , p y This completion will completely isolate andp p g ( p abandon the parent Ivishak perfs. Sundry 324-082 PTD 224-011 8. Close in tree, RDMO. * Approved alternate plug placement per 20 AAC 25.112(i) Post Rig Work: 1. Valve Shop : Valve & tree work 2. Coil : RPM, ~100' of i-perfs See perf procedure attached 3. Slickline : SBHPS, set LTP (if necessary). Set live GLVs. Window Milling Fluids Program: 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. The well will be freeze protected with a non-freezable fluid (typically a 60/40 methanol/water mixture) prior to service coils departure. Additionally, all BHAs will be lubricated and there is no plan to open hole a BHA. Disposal: All Class l & II non-hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS 4. Fluids >1% hydrocarbons or flammables must go to GNI. Fluids >15% solids by volume must go to GNI. Hole Size: The window and 10 of formation will be milled/drilled with a 3.80 OD mill. Well Control: BOP diagram is attached. 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. Pipe rams, blind rams, CT pack off, and choke manifold will be pressure tested to 250 psi and at least 3,500 psi. 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. BOPE tests will be performed upon arrival (prior to first entry into the well) and at 7 days intervals thereafter. 20 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: H is not an H2S pad. H2S reading on H-18: 15 ppm on 10/05/2021. Max H2S recorded on H Pad: 64 ppm. Reservoir Pressure: The estimated reservoir pressure is expected to be 3,386 psi at 8,800 TVD. (7.4 ppg equivalent). Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,506 psi (from estimated reservoir pressure).

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 i • BP Exploration (Alaska) Inc.

In order to accurately quantify the flow of fluids, a production logging suite was run. The flowing PL analysis showed 78% of the oil production to be coming from 9448.5’ – 9458’ while the remaining from 9458’– 9467’. Majority (96%) of the gas production is coming from 9391.5’ – 9448.5. Zone from 9497.5’ – 9539.5’ contributed all the water production. The status of each perforation is indicated in the table below. The interpreted production rates are slightly lower than the reported flow rates.

The software uses a global probabilistic method for the production log analysis. In this method, known as the Maximum Likelihood method, a well flow model is compared to all available data and improved, by optimization, until the best possible match with the data is obtained. By using this method the result is the most likely interpretation. A comparison between the model and the data is shown in this report and allows t he analyst or the reader to determine validity of the answer obtained. Potential sources of discrepancies include tool measurement errors, conflicts between the parameters or conditions that make the underlying empirical models (such as flow regimes) less applicable.  The flow regimes were determined, directly from the flow rates and holdups, according to the Taitel- Dukler analytic model.  The profile factors, to calculate the true fluid velocity from the apparent velocity, were based on the Reynolds numbers.  Solution gas in oil was derived from the correlations (Vasquez-Beggs or Øistein- Glaso). The analysis was performed in five steps:  The data preparation to filter the data, compute gradients and error estimates.  The flow meter analysis to compute the apparent velocity.  The profile determination to identify the potential producing and/or injecting zones.  The computation of the flow rates by global optimization.  The computation of surface productions and reporting.

For the interpretation, all the passes have been used. For spinner analysis, DOWN passes were excluded. From the raw data, various trends can be observed. Almost all the gas production is coming from 9391.5’ to 9448.5’ (CFS, ILS and capacitance increase, density log values decrease to about 0.16 g/cc and gas holdup values drop significantly). The inline and fullbore spinners move steadily across the bottom perforations indicating some flow while density stays around 1 g/cc indicating water production. Capacitance data is also responsive, for example, increasing significantly across the large gas production. From the spinner response, the velocity profile was estimated using the slopes calculated from the spinner calibration (Figure 5). The estimated spinner velocities, densit y and gas holdup are used to calculate the flow profile. The final flow profile, after global optimization, along with the comparison of the measured and theoretical tool values are presented in Figure 7. The production rates at surface conditions estimat ed from the production log analysis are presented in Figure 8 and are summarized in the table below: Perforations Q- Water Qp- Water Q-Oil Qp-Oil Q-Gas Qp-Gas From, ft To, ft Status BFPD BFPD BFPD BFPD MCFD MCFD 9391.5 9448.5 Squeezed 2027 0 752 0 23875 22900 9448.5 9458 Squeezed 2027 0 752 585 975 209 9458 9467 50% Squeezed 2027 0 167 167 766 63 9477.5 9495 Squeezed 2027 0 0 0 703 702 9497.5 9539.5 Open 2027 2027 0 0 1 1 BP Exploration Alaska Production Array Log Analysis 10 Raw Data  The figure below summarizes the input data recorded at the well site during flowing passes.  Each pass is shown with a fixed predefined color.

The figure shows a comparison between the flowmeter data and the flowmeter values calculate d for each cable speed, with the globally determined slope and intercept. Only UP ILS passes have been used. For each cable speed a different color is used. The data is shown as solid lines and the calculated values in dotted lines. Figure 5: Velocity pro file from spinner data BP Exploration Alaska Production Array Log Analysis 13 The image below displays cross plots for the Inline spinner. The estimated slopes are used for converting the spinner response to flow velocities. Figure 6: Spinner cross plot BP Exploration Alaska Production Array Log Analysis 14 Flow Profile The quantitative production rates were determined by comparing the well flow model with all available data. The figure below is provided to verify the agreement of the flow model with the data. In this figure the data is represented by the blue curves, while the calculated tool values are shown in red. The uncertainty interval is represented as a gray band around the data. The uncertainty interval corresponds to one standard deviation. Capacitance is used qualitatively. The small fluctuations around the data are to be expected, since the tools have intrinsic errors. Large sustained discrepancies indicate problems with the data, conflicts between parameters or conditions that make the underlying empirical models less applicable. To the right of the figure the flow regimes are shown. Within the transition zones several regimes can exists intermittently.
