Anticipated Surface Pressure:2,499 psi (Based on 0.1 psi/ft. gas gradient) Last SI WHP:1,950 psi (Taken on 12/26/24) Min ID:1.81” ID ‘Sag Straddle’ @ 9,392’-9,444’ MD Max Angle:93 Deg @ 11,249’ Brief Well Summary: 05-30 was drilled in October 1991 and completed as a Z1A producer with a slotted liner. The tubing was swapped in 2011. In 2017 Sag river perfs were added and comingled with Z1A. By 2019 the well was high GOR. A LDL found a PC leak at 5,507’ with a LLR of 2.7bpm at 2,350-psi. In 2021 the tubing passed an MIT-T to 2,500- psi. The Sag river perfs were patched and the well Pop’d under a 60 day eval period. The well flowed at 800- 900 IOR during the eval time. We will now pursue a RWO to repair the PC leak. We will install a fully cemented 7” longstring then run a 4-1/2” chrome gas lifted completion. The well is currently secured with a PX plug in the packer tailpipe. Objective: Pull 4-½” tubing out of the well. Set lower tieback. Run 7” longstring and cement to surface. Add tubing spool. Drill-out shoe tract, pull RBP. Run new 4-½” 13Cr gas lifted completion. Achieve a passing MIT-IA & MIT-T. Pre RWO work: DHD – MIT-T – 2,500-psi Cycle LDS’s PPPOT-T – 5,000-psi E-line - Cut tubing at 8,889ft (10ft down on first full joint of tubing) Fullbore Circ out wellbore with 9.8ppg brine and diesel cap.

A subsequent LDL on 11/30/2019 found a PC leak at 5540’ MD. In 2021 the well was flowed under eval for 60 days to determine if well production would support repair of the PC leak, but the well was not found to be economic. The current plan is to patch over the Sag perforations at 9402-9433’ MD and flow the well just from the Ivishak slotted liner to determine if production rates are sufficient for the repair work. A MIT-T passed on 5/6/2024 to 2595 psi with a plug set in the tubing at 8997’ MD. Hilcorp requests permission to flow the well under eval for up to 60 days to evaluate production rates for well economics to support repair of the production casing. Gas lift will not be used, dummy gas lift valves are set. The IAP will be maintained below MOASP and the well resecured at the end of the under eval period.

Attahment ir Duplicate To: Alaska Oil & Gas Conservation Commission From: Nathan Sperry - CTD Engineer p Date: February 12, 2020 Re: 05-30 Sundry Approval Request Sundry approval is requested to plug off the 05-30 production as part of the drilling and completing the proposed 05-30A coiled tubing sidetrack. History of 05-30 05-30 was originally completed in 1991 and worked over in 2011. 05-30 has gassed out and there are no additional weliwork options to improve the oil rate. There is also a casing leak at 5,540' MD in the Cretaceous (top of UG4 is 4806' MD). Economics The geologic target being pursued cannot support a rig workover to fix the IA leak and a CTD sidetrack. Without an IA remedial squeeze, this well has no utility in the foreseeable future and the target would likely not be pursued. IA Cement Detail The PC leak will be remediated by placing cement between the 4-1/2" tubing and the 9-5/8" casing. A composite plug will be set at 8,950' MD and the tubing punched just above that. A composite retainer will be set at 8,930' MD and coil tubing will place ^265 bbls of 15.8ppg cement in the IA to 5,000' MD. The top of the UG4 is 4806' MD. The surface casing shoe is at 3498' MD. Long term integrity monitoring will include daily recording of the WHP's and biennial CMrr-T%IA's. Proposed plan for 05-30A The sidetrack will be a `3010' horizontal CST that will kicks -out from the 05-30 parent. The CST will establish offtake in the Sag River. The sidetrack will be drilled on or around September 2020. During pre -rig work, it is proposed to set a 3-1/2" whipstock at a kickoff depth of 9570' MD, cement the IA behind the KOP, and cement the IA above the packer to 5,000' MD to fix the casing leak. The rig will move in, test BOPE, mill the window, and drill into the Sag River formation. The proposed sidetrack will be completed with 2-3/8" 13Cr-80 solid liner and cemented in place. This Sundry covers Plugging the existing 05-30 Production 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 and is submitted as an attachment to Form 10-403. A schematic diagram of the current well and proposed sidetrack is attached for reference.

This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." 4 When the Stat Tech receives any Form 10-407, they will check the Stat Tech History tab in RBDMS for the "Intent: Plug for Redrill" code (IPBRD). If present and there is no evidence that a subsequent re -drill has been COMPLETED, the Stat Tech will assign a status of SUSPENDED to the well bore in RBDMS no matter what status is listed on the 10-407. The Stat Tech will also change the status on the 10-407 form to SUSPENDED, and date and initial this change. If the Stat Tech does not see the "Intent: Plug for Redrill" comment or code, they will enter the status listed on the Form 10-407 into RBDMS. 5 When the Form 10-407 for the redrill is received, the Stat Tech will Stat Tech change the original well's status from SUSPENDED to ABANDONED. 6 The first week of every January and July, the Stat Tech and one of the Stat Tech Geologists will check the "Well by Type Work Outstanding" user query Geologist in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, they will also review the list of suspended wells for accuracy. • • STATE OF ALASKA • ALASKA OIL AND GAS CONSERVATION COMMISSION REPORT OF SUNDRY WELL OPERATIONS 1.

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.

The restrictions were successfully milled out and the casing pressure tested 3,000 -psi for 30 charted minutes. We will revert back to the original plan and run new tubing. The casing will again be pressure tested after setting the new production packer. Thank you for the help and consideration while we were performing diagnostic work and formulating a plan forward.

The original scope of 1/24/2011 05 -30 RWO (PTD 1911150) API 5429- 22213 -00 Page 2 of 2 work was a tubing swap and casing pack -off change -out. While running in the hole with the dress -off assembly we encountered a tight spot in the 9 -5/8" casing around 6,400ft. Judging from the marks on the dress off assembly it appears we have some collapsed casing. We will run a PDS 40 ARM caliper to evaluate. More than likely we will end up installing a 7" scab liner to cover up the casing damage at 6,400'. Here is a proposed drawing. I will send a scope of work when I get it completed. We would like verbal approval to proceed with the formal paperwork to follow Monday. Please call me if you have any questions.

WELL SUMMARY WELL SUMMARY Teleco's measurement while drilling service was utilized on Prudhoe Bay Drilling Inc.'s well #DS5-30 located in the Prudhoe Bay field on the North Slope of Alaska. Teleco was used to provide directional data, surveys, and logs throughout the course of the well. The gamma ray and dual propagation resistivity log (DPR) was used through correlation to identify lithologies, pick formation boundaries, and to select a 9 5/8 inch casing point. Gamma ray, resistivity, neutron and density (Triple Combo) service was used as log of record to identify lithologies, formation boundaries, gas-oil contacts and well TD. Directional service began at 3505 feet on September 12, 1991. Logging service commenced at 7705 feet measured depth and was used to a total measured depth of 12,000 feet. The 7 3/4 inch directional tool was used to drill 4200 feet with 73.5 circulating hours. The 7 3/4 inch DPR tool was used to log 1826 feet with 41.5 circulating hours. Triple Combo services with 6 3/4 inch tools were used to log 2569 feet with 72.0 circulating hours. Service ended on September 27, 1991. III. DRILLING AND ENGINEERING DRILLING AND ENGINEERING RUN NO 1 & 2:3505 TO 7705 FEET MD, 12 1/4 INCH HOLE TOOL NUMBER AND TYPE: 257-63, 4X DTF-1 Surface casing was set at 3497 feet. Teleco was then utilized for directional service to drill out of casing and for kick-off #1 at the start of the 12 1/4 inch section of the hole. Surveys were taken every stand in order to ensure well path control. Directional service was completed with a total 73.5 circulating hours. Directional control was established and maintained with the use of a 1 degree bent housing steerable mud motor by sliding and rotating with this assembly. The maximum dogleg for run no. 1 was 3.79 degrees per 100 feet. For run no. 2, the maximum dogleg was 0.92 degrees per 100 feet. Run no. 2 ended with an angle of 40.0 degrees. The directional tool was laid down at this point for a service upgrade. RUN NOS. 3 THRU 5: 7705 TO 9531 FEET MD, 12 1/4 INCH HOLE TOOL NUMBER AND TYPE: 1757-53, 4X DTF-3 Teleco continued to provide directional service and began DPR logging services through this section of hole for correlation and to pick 9 5/8 inch casing point. A 1 degree bent housing steerable mud motor was used with Teleco for directional control during these runs with directional surveys recorded, approximately every 95 feet. Runs 3 and 4 were made using this assembly in order to maintain directional control through the hole section between kick off point no. 1 and no. 2 with maximum doglegs of 0.67 & 1.32 degrees per 100 feet, respectively. Run no. 4 had a final angle of 51.4 degrees. Run number 5 was made from 9182 to 9531 feet MD. The same steerable motor was made up with Teleco to build angle and steer the well path into the second kick-off. The wellbore was built from 51.4 to 54.1 degrees before casing point was chosen and DPR service was terminated. Maximum dogleg for this run was 5.8 degrees per 100 feet. These five runs were made without a Teleco failure. Teleco was laid down after 41.5 circulating hours of DPR service and a total of 115.0 hours (including directional service) for a service upgrade and to run 9 5/8 inch casing. RUN NO 6: 9531 TO 9911 FEET MD, 8 1/2 INCH HOLE TOOL NUMBER AND TYPE: 1677-02, 4X MOD TF-1 Teleco's Triple-Combo service was employed for this section of the hole for correlation purposes in addition to formation evaluation. This service provided density, neutron porosity, dual propagation resistivity, natural formation gamma ray, and bottom hole circulating temperature measurements in addition to directional information. For this run a packed rotary assembly was used, but had to be pulled due to a left-hand walk at 9911 feet with 62.8 degrees of inclination. During this run Teleco experienced two failures of modular tools, the first failure was a density sub which began operating intermittently. This resulted in several data gaps in the memory log. The second was a memory sub failure which lost one quarter of its internal memory. Teleco's memory subs incorporate two redundant memories to safeguard against memory loss, which was successful in the protection of this run's formation data. RUN NO 7: 9911 TO 10289 FEET MD, 8 1/2 INCH HOLE TOOL NUMBER AND TYPE: 1677-02, 4X MOD TF-1 Teleco's triple combo service was used again for run number 7 to provide formation evaluation and for correlation purposes. A 1 degree bent housing motor was utilized for directional control. At the start of this run a checkshot survey was taken and the results agreed with the Teleco surveys. During the run directional surveys were run frequently to check the well path. RUN NO 8:10289 TO 11228 FEET MD, 8 1/2 INCH HOLE TOOL NUMBER AND TYPE: 1677-02, 4X MOD TF-1 Teleco's Triple-Combo tool string was made up with a rotary build assembly for this run which achieved an average build rate of 2.26 degrees per 100 feet and had a maximum dogleg of 2.67 degrees per 100 feet. The inclination was increased from 70.5 to 91.8 degrees in 15 circulating hours. Teleco did not have any failures this run and formation evaluation and lithological correlation was successful. This hole segment also contained a section of relog which was performed after Run 9, from 10280 to 10610 feet md. This run was terminated to pick up a packed rotary assembly to complete the inverted horizontal portion of the wellbore. RUN NO. 9: 11228 TO 12000 FEET MD, 8 1/2 INCH HOLE TOOL NUMBER AND TYPE: 1677-02, 4X MOD TF-1 A packed rotary assembly with Teleco's TC was tripped in the hole for Run 9. Drill rates varied with lithologies from 20 foot per hour to 70 foot per hour in sands. Angle was built from 91.8 degrees to 93.3 degrees, and then dropped to 88.8 degrees at TD. 772 feet of horizontal and inverted wellbore were completed during this run with 27 hours on bottom, the assembly was pulled to the shoe for the relog of the section mentioned in Run 8. Teleco experienced no trouble on this run and tools operated properly for the duration of this run and relog.

FORMATION EVALUATION FORMATION EVALUATION DS5-30 was drilled as a horizontal production well for Prudhoe Bay Drilling in the Prudhoe Bay Unit, located in the North Slope Borough of Alaska. Teleco dual propagation resistivity (DPR) services were used to identify known stratigraphic markers and pick the 9 5/8 inch casing point for the 12 1/4 inch hole. Triple combo logging services were used to perform a log analysis in the 8 1/2 inch hole and became log of record due to the high angle nature of the well. The triple-combo logging tools combine a dual propagation resistivity measurement, gamma ray, neutron porosity, bulk density, and directional services into a package that provides both downhole memory and real time data transmission to the surface. A 2 MHz electromagnetic wave is used to determine the resistivity measurement. Both phase difference and amplitude ratio resistivities are recorded providing a dual depth of investigation measurement. Of the two resistivity measurements the amplitude ratio gives the deeper depth of investigation. Natural formation gamma ray is provided by a scintillator detector which gives more accurate readings and allows for a higher data rate than earlier detection methods. Teleco's neutron tool utilizes a 5 curie Americium- Beryllium neutron source with two Lithium 6 detectors to provide a compensated neutron porosity measurement. The density tool uses a 2.5 curie Cesium 137 source which enables the two detectors to give a compensated bulk density and density porosity in addition to a photoelectric effect measurement and the density correction delta rho. Logging began slightly above the K-10 marker at a depth of 7705 feet measured depth. All depths referred to in this section are measured depths below the kelly bushing. Drilling continued through the Prince Creek-Schrader Bluff formations to the K-10 marker at a depth of approximately 7720 feet. The K-10 marker was picked using the gamma ray in conjunction with resistivity log response. Gamma ray was displaying a fluctuating response at the beginning of the logged interval with an abrupt drop to a slightly lower more stable level, while resistivity experienced a slight increase in value. The K-10 was picked where the gamma ray returned to its previous level. Directly above the K-10, some notable fluctuations were seen in both the gamma and resistivity logs. The K-10 marks the top of the Seabee formation. The Seabee formation, consisting primarily of interbedded siltstones and clays, typically fine to very fine grained, was drilled from the base of the K-10 marker to the end of bit run no. 3 at 8899 feet sensor depth. During this run the K-5 marker was encountered at a depth of approximately 8612 feet. Directly above the marker, there was a noted increase in gamma values as well as a slight increase in the resistivity curve. The K-5 occurred where the resistivity and gamma ray curves both dropped back to distinctly lower values. At a depth of approximately 8992 feet, the K-2 marker was seen on the log. This distinctive marker appeared as a sharp decreasing spike on the resistivity log. At the same time, the gamma trace began its upward ramp indicating the beginning of the HRZ directly below the K-2 marker. This zone is noted by its characteristic high gamma values. The Sag River sandstone appeared at a depth of approximately 9390 feet measured depth. This zone is best characterized by its abrupt, dramatic increase in the resistivity curve. It is also noted by several ratty spikes in the gamma trace near the top of the zone, which settle down to a level lower than previous formations. The last interval logged with the DPR tool, prior to pulling out of the hole for casing was at a depth of 9458 feet. At this point the traces indicated the beginning of the Shublik formation by the slight erratic nature of both the gamma ray and resistivity curves. The Shublik formation underlies the Sag River sand, the top of which was not logged due to the sensor standoff to the bit at casing point. The Shublik containing calcareous siltstone, shale and limestones was drilled to a depth of 9570 feet when a clean sand was drilled marking the top of the Sadlerochit group. This being a inverted horizontal production well the deepest vertical depth reached was within the Sadlerochit at a measured depth of approximately 11080 feet. Log response for the Sadlerochit indicated zones primarily of clean sandstones and siltstones interbedded with siltstone and shale. Approximately 920 feet of horizontal section was drilled accompanied by an approximate 20 feet of inverted vertical section. Neutron near/far overlays and neutron porosity/density porosity overlays were essential in gas -oil contact picks in an effort to keep the well path from re-entering or approaching any gas intervals. The quality of the real time log varied over the course of the well, ranging from excellent to fair. New signal filtering capabilities were used successfully in data acquisition over the course of the high angle section. The memory log was unaffected by any of the drilling parameters and provided an excellent high resolution log throughout the course of the well. V.

Nipple up BOPs and test same to 5000 psi. Pick up 12 1/4" BHA and drill 10' of new hole and perform leakoff test. Drill vertical hole to 3900'tvd/md (KOP#1). Then build 'ang!e at 2.5 degrees/100' in the N 37' 47" E direction to 40.96 degrees at 5402'tvd/5538'md (EOC#1). Hold angle at 40.96 degrees to 8012'tvd/8994'md (KOP#2). At KOP#2, begin building angle again at 2.5 degrees/100'md in the N 37' 47" E direction to 8355'tvd/9501'md (9 5/8" casing point). · Set 9 5/8" casing and cement same. PU 8 1/2" BHA and test casing to 3000 psi. Drill 10' of new 8 1/2" hole and perform formation integrity test to 12.5 ppg EMW. Switch to oil base mud, then drill 8 1/2" hole while continuing to build at 2.5 degrees/100'md to 92 degrees at 8800'tvd/11036'md (EOC#2 and 7" casing point). At EOC#2, maintain angle (92 degrees) and direction of N37' 47"E to TD of 8765'tvd/12036'md. (Sadlerochit formation will be logged via MWD tools). RIH and spot polymer/salt pill at the 7" set point of 8800'tvd/11036'md (false bottom). Run and set the 7" liner at 8800'tvd/11036'md and cement same. (NOTE: The 7" casing point may change due to the depth of the gas-oil contact). Clean out 7" liner and test to 3000 psi for 30 minutes. RIH with cement evaluation logs. Clean out open hole and set 4 1/2" slotted liner and production packer. Circulate well to brine. Run 4 1/2" x 3 1/2" tubing string. Freeze protect well. NU tree and test to 3000 psi. Release rig. / ECEIVED Alas/~a 0il & Gas Cons. C0mmissien Anchorage DS5-30 Operations. Summary-continued a. Excess non-hazardous fluids developed from well operations and as necessary to control fluid level in reserve pit will be pumped down the 13 3/8" x 9 5/8" annulus. The annulus will be left with a non-freezing fluid during any extended period and will ultimately be sealed with 300 sxs of cement followed by Arctic Pack. b. Wells within 200' of the proposed well are (depths are relative to DS5-30) DS5-31: 178' at 1580'md and diverges at 4400'md. DS5-16: 103' at 3940'md and diverges at 3940'md. DS5-15: 106' at 4140'md and diverges at 4140'md. DS5-26: 85' at 2580'md and diverges at 2580'md. DS5-23: 60' at surface and diverges at surface. c. The drilling fluid program and fluid surface system will conform to the regulations set forth in 20AAC25.033. d. The maximum surface pressure is based upon the BHP and a full column of gas to TD (0.10 psi/ft). e. Based upon previous logs obtained from DS5 wells, no productive zones are anticipated above 4000'tvd. f. No hazardous levels of H2S are anticipated in this well.
