Huber, Sr. Date: 2024.04.23 15:16:44 -08'00'04/23/24 RBDMS JSB 042624 To: Alaska Oil & Gas Conservation Commission From: Ryan Ciolkosz Drilling Engineer Date: April 17, 2024 Re: 18-07C Sundry Request Sundry approval is requested to set a whipstock and mill a window in the 18-07C wellbore as part of the drilling and completion of the proposed 18-07D CTD lateral. Proposed plan for 18-07D Producer: Prior to drilling activities, screening will be conducted to pull LTP, drift for whipstock, and caliper. E-line will set a 3-1/4" packer whipstock and coil will mill the window pre-rig if unit is available. If unable to set the whipstock or mill the window, the rig will perform the work. See 18-07D PTD request for complete drilling details A coil tubing drilling sidetrack will be drilled with the Nabors 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 3- 1/4" whipstock. A single string 2.74" window + 10' of formation will be milled. The well will kick off drilling in the Ivishak and lands in Ivishak Zone 1. The lateral will continue in Zone 1 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. This Sundry covers plugging the existing 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 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 May 1st, 2024) 1.Slickline : Dummy GLV, pull liner top, caliper, drift for whipstock 2. E-Line : Set 3-1/4" Packer Whipstock - 12,138' @ 120 deg RHOS 3.Coil : Mill 2.74" Window** 4.Valve Shop : Pre-CTD Tree Work 5. Operations : Remove wellhouse and level pad. Rig Work: (Estimated to start in June 2024) 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2,460 psi). Give AOGCC 24hr notice prior to BOPE test. 2. Mill 2.74” Window. (If not done pre-rig) 3. Drill build section: 3.25" OH, ~264' (34 deg DLS planned). 4. Drill production lateral: 3.25" OH, ~1941' (12 deg DLS planned). 5. Run 2-3/8” 13Cr liner with 3.7" deployment sleeve 6. Pump primary cement job: 20 bbls, 15.3 ppg Class G, 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. Close in tree, RDMO. * Approved alternate plug placement per 20 AAC 25.112(i) **if scheduling needs arise, rig will mill window Post Rig Work: 1. Valve Shop : Valve & tree work 2. Slickline : set LTP* (if necessary). Set live GLVs. Nabors CDR3 rig. PTD Sundry 324-225 3. Service Coil : Post rig perforate (~1000’) 4. Testing : Portable test separator flowback. 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 (~503 psi over-balance). 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 or Pad 3. x Fluids >1% hydrocarbons or flammables must go to Pad 3. x Fluids >15% solids by volume must go to GNI. Hole Size: x The window and 10’ of formation will be 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 18 is not an H2S pad. H2S reading on 18-07C: 38 ppm on 10/27/2023. x Max H2S recorded on DS/Pad: 38 ppm. Reservoir Pressure: x The estimated reservoir pressure is expected to be 3,340 psi at 8,800 TVD. (7.3 ppg equivalent). x Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,460 psi Give AOGCC 24hr notice prior to BOPE test (from estimated reservoir pressure). Ryan Ciolkosz CC: Well File Drilling Engineer Joe Lastufka 907-244-4357 H2S reading on 18-07C: 38 ppm on 10/27/2023. If first well for CDR3 for Hilcorp, BOPE will be tested to 5000 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.

Anticipated Surface Pressure:2,464psi (Based on 0.1 psi/ft. gas gradient) Last SI WHP: 1,040psi (Taken on 02/17/2022 DHD) Min ID:2.31” ID – X Nipple @ 11,583’MD Max Angle:110 Deg @14,650’ Reference Log: PDLC GR 16-Oct 2015 Brief Well Summary: 18-07C is a CTS completed in Z1B in Oct 2015. The original toe and mid lateral perfs are currently uncompetitive. Objective: The objective of this procedure is to plug the current perforations and shoot additional Z1B perforations from 13,112-13,212 (100ft). Sundry Procedure (Approval Required to Proceed): Notes: x Remote gas monitoring for H2S and LELs are required for Open Hole Deployment Operations x Due to the necessary open hole deployment of Extended Perforating jobs, 24-hour crew and WSS coverage is required. x The well will be killed and monitored before making up the initial perfs guns. This will provide guidance as to whether the well will be killed by bullheading or circulating bottoms up throughout the job. If pressure is seen immediately after perforating, it will either be killed by bullheading while POOH or circulating bottoms up through the same port that opened to shear the firing head. Coil Tubing 1. MIRU Coiled Tubing Unit and spot ancillary equipment. 2. Bullhead 220 bbls of KWF, 8.4 ppg 1% KCl or 8.5 ppg down the tubing to the formation. (This step can be performed any time prior to open-hole deployment of the perf guns. Timing of the well kill is at the discretion of the WSS.) a. Wellbore volume to top perf = 195 bbls b. 4-1/2” Tubing – 11,573’ X .0152bpf = 176 bbls c. 3-1/2” Liner - 29’ X .0087bpf = 0.25 bbls d. 3-1/4” Liner - 907’ x .0079 = 7.2 bbls e. 2-7/8” Liner – 1,891’ X .0058bpf = 11 bbls 3. MU and RIH with logging tools and drift BHA to resemble 1.75” dmy gun. Run past 13300’ctmd and log OOH. 4. POOH and confirm good data. 5. Freeze protect tubing as needed. o plug the current perforations a 2,464psi shoot additional Z1B perforations from 13,112-13,212 (100ft). Extended Perf Procedure 18-07C PTD:215-138 6. RIH and set 2-7/8” CIBP at ~13,280ft. (Note min ID is X nipple at 11,583’). Verify tubing is full and pressure test to 500-psi. 7. At surface, prepare for deployment of TCP guns. 8. Confirm well is dead. Bleed any pressure off to return tank. Kill well w/KWF, 8.4 ppg 1% KCl or 8.5 ppg as needed. Maintain continuous hole fill taking returns to tank until lubricator connection is reestablished. 9. *Perform drill by picking up safety joint with TIW valve and space out before MU guns. Review well control steps with crew prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety joint and TIW valve have been spaced out, keep the safety joint/TIW valve readily accessible near the working platform for quick deployment if necessary. a.At the beginning of each job, the crossover/safety joint must be physically MU to the perf guns one time to confirm the threads are compatible. 10. Break lubricator connection at QTS and begin makeup of TCP guns and blanks per schedule below. 18-07C Addperf Schedule *HES 1.75” Geo Razor guns were used to estimate for this job. 1.91” gun swell 11. MU lubricator and RIH withperf gun and tie-in to coil flag correlation. Pickup and perforate interval per Perf Schedule above. POOH. a. Note any tubing pressure change in WSR. 12. POOH. Stop at surface to reconfirm well dead and hole full. 13. Review well control steps with crew prior to breaking lubricator connection and commencing breakdown of TCP gun string.

The proposed sidetrack is a -3195' horizontal Zone 1A producer, which will target Zone 1A in western DS -18, just north of the Mid -field graben. The lateral will be completed with a 3-1/2" x 3-1/4" x 2-7/8" L-80 solid liner and will be cemented to the top of the liner at 11,590' MD and selectively perforated. The existing perf intervals and 18-07B sidetrack attempt are below the KOP and will be isolated via the packer whipstock set pre -rig and the liner cement job or liner top packer.* The 18-07B sidetrack attempt in October 2014 was suspended due to extremely high fluid losses. The KOP for this sidetrack is -400' higher than the initial attempt and should allow us to avoid the fault crossing where losses were encountered. scheduled to be in Au ust 15, 2015 test BOPE 250 si low and 3,500 si hi h.
