The submitted suspended well inspection reflects the current condition of the well (reference 20 AAC 25.110 (f)) and supports the request for renewal of suspension. Recent events from this well indicate that this well is mechanically sound. Specific attachments include: x Suspended Well Site Inspection form documenting the pressures and site condition. x Wellbore diagram illustrating the current configuration of the well. Prudhoe well G-30C was suspended on 07/27/2014 and has future utility as a rig sidetrack candidate. The strata through which the well was drilled is neither abnormally geopressured nor depleted. The well is mechanically sound, passing a MIT-IA to 3596 psi on 11/06/2015. Based on these conditions and the inspection on 07/31/2023, Prudhoe well G-30C meets the provisions required in 20 AAC 25.110 (a)(1). Hilcorp North Slope, LLC requests approval for renewal of the existing suspension status for this well. Attached is an Application for Sundry Approval (10-403) with a technical justification summarizing the information on the current status and condition of the well (reference 20 AAC 25.110 (a), (b), (e), (h)). In summary, Hilcorp believes Prudhoe well G-30C is mechanically sound and secure and meets the requirements for renewal of suspended status. If you have any questions, please call me at 406-570-9630 or Oliver Sternicki at 907-564-4891.

The well was then rotary sidetracked in 1995 and had 2 CTD sidetracks in 2006 and 2010. G-30C was drilled and completed as an Ivishak producer in April 2010. In mid-2012, G-30C was no longer competitive, reaching MGOR and work for the G-30D CTD sidetrack began with Nordic 2 in April 2013. G- 30C was reservoir abandoned under Sundry 313-122, but the well failed subsequent MIT-Ts against the whipstock (8945’ MD) and the cement placed in the 3.5’ tubing x 7” liner annulus. The liquid leak rate of the failing MIT-T was 0.17 bpm at 2000 psi. Due to gas entering the wellbore from the suspected leaking 7” liner top at 6456’ MD, the CTD sidetrack was canceled and the well went into operations shutdown status. The well was suspended on 07/27/2014. A tubing tail plug was set at 6418’ MD on 07/27/2014 and the well passed a MIT-IA to 3596 psi on 11/6/2015. The well future utility is as a sidetrack candidate. The well will not allow the migration of fluids, will not damage freshwater or producing or potentially producing formations, will not impair the recovery of oil or gas, and is secure, safe and not a threat to public health. The strata through which the well was drilled is neither abnormally geo-pressured or depleted. Condition of the Wellhead and Surface Location Prudhoe well G-30C is located on an active, well maintained pad with clean gravel. The pit and surrounding area are in good condition. There is no discoloration and no sheens on the pad, pits, or in nearby water. The well pressure readings are T/I/O = 20/ 200/ 380 psi. Request Hilcorp North Slope, LLC requests approval for renewal of the existing suspension status for G- 30C. A variance to the provisions of 20 AAC 25.110 (c) (2) is also requested under 20 AAC 25.112 (i) to allow the well to remain as suspended in its current condition. All hydrocarbon intervals are isolated and there are no underground sources of fresh water in this area. Suspended Well Inspection Review Report Reviewed By: P.I.

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 Geologist in the upper left corner of Form 10-403 is checked. If the "Abandon" or �Y "Suspend" boxes are also checked, cross out that erroneous entry and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2 If the "Abandon" box is checked in Box 15 (Well Status after proposed Geologist work) the initial reviewer will cross out that erroneous entry and initial then it on both copies of the Form 10-403 (AOGCC's and operator's copies). y1 Instead, check the "Suspended"box and initial that change. Drilling `—' Engineer The drilling engineers will serve as quality control for steps 1 and 2. (QC) 3 When the Stat Tech receives a Form 10-403 with a check in the"Plug Stat Tech 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." 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.

History and current status: G -30 was drilled and completed in August -1986. The well has had a rotary sidetrack in 1995, and 2 CTD sidetracks in 2006, and 2010. G -30C was drilled and completed in April -2010. The well has a Bonzai completion, with the second half of the liner being slotted liner. Only the slotted liner was produced initially. Cycling was tried on the well, but the well was uncompetitive. The slotted liner was shut off Sept -2011, and perfs added. The well gassed out in 3 weeks. Another plug/perf was executed July -2012, and the well came on right at MGOR. There are no remaining non -rig intervention options to return the well to competitive status. Proposed plan: Sidetrack G -30C to the G -30D location using Nordic 2 Coiled Tubing Drilling rig on or around April 1, 2013. The G -30D sidetrack will exit the existing 3.5" liner and kick off in Zone 4 and land in Zone 1. This sidetrack will be completed with a 2 -3/8" L -80 liner and cemented in place. This Sundry covers plugging the existing G -30C perforations via the G -12C primary liner cement job and a 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 proposed sidetrack is attached for reference. 1 (cvicof. 141f we I I k ' f i e vet eel"?

' • • Page 1 of 1 Subject: FW: INTENT PLUG for RE -DRILL WELLS: Corrected From: Davies, Stephen F (DOA) Sent: Monday, February 08, 2010 10 :52 AM To: Foerster, Catherine P (DOA); McMains, Stephen E (DOA); Schwartz, Guy L (DOA); Saltmarsh, Arthur C (DOA); Aubert, Winton G (DOA) Subject: RE: INTENT PLUG for RE -DRILL WELLS: Corrected Revised procedure with an additional step per Cathy's comment: INTENT PLUG for RE -DRILL WELLS (IPBRD) Type Work Code in RBDMS 1. When a Form 10 -403 is submitted requesting approval to plug a well for redrill, the initial reviewer (Art or Steve D.) will check to make sure that the "Plug for Redrill" box in the upper left corner of the 403 form is checked. If the "Abandon" box is checked, we will cross that erroneous entry out and initial it on both copies of the Form 10 -403 (AOGCC's and operator's copies). / 2. On the Form 10 -403 if "Abandon" is checked in Box 15 (Well Status after proposed work), Art or Steve D. will cross that erroneous entry out and initial it on both copies of the Form 10 -403 (AOGCC's and operator's copies). Instead, we will check the "Suspended" box. Guy and Winton will serve as quality control for steps 1 and 2. 3. When Steve McMains receives the Form 10 -403 with a check in the "Plug for Redrill" box, he will enter the existing code "IBPRD" into RBDMS. This code automatically generates a comment under the History tab stating "Intent: Plug for Redrill." 4. When Steve McMains receives any Form 10 -407, he will check the History tab in RBDMS for this comment. If he sees the "Intent: Plug for Redrill" code, and cannot find any evidence that a subsequent re -drill has been COMPLETED, he will assign a status of SUSPENDED to the well bore in RBDMS, no matter what status is listed on the 10 -407. Steve will also change the status on the 10 -407 form to SUSPENDED, and will date and initial his change. If Steve does not see the "Intent: Plug for Redrill" comment or code, he will enter the status listed on the Form 10 -407 into RBDMS. 5. When the Form 10 -407 for the redrill is received, Steve M. will change the original well's status from suspended to abandoned. 6. The first week of every January and July, Steve M. and Steve D. will check the "Well by Type Work Outstanding" user query in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, Steve M. and Steve D. will also review the list of suspended wells for accu racy.

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.

Hole size: 3" • Casing Program: • 2 -3/8 ", 4.7 #, L -80, STL solid 9,000' MD — 10,300' MD BonZa; • 2 -3/8 ", 4.7 #, L -80, STL slotted 10,300' MD - 12,130' MD • • A minimum of 6 bbls of 15.8 ppg cement will be used for liner cementing. (cement from 10,300' to TOC at 9,000'MD) Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 2,500 psi. Directional • See attached directional plan. Maximum planned hole angle is 91 deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property line — 16,200' South • Distance to nearest well within pool — 885' (G -06A) Anticollision Summary • No anti - collision issues Logging • MWD directional and Gamma Ray will be run over all of the open hole section. • A cased hole GR/CCUCNL log will be run. Hazards • The maximum recorded H2S level on G -Pad is 20 ppm on well G -10C (04 -20- 2009). G -Pad is not an H2S pad. • Lost circulation risk is moderate (average). No fault crossings are expected and the occurrence of losses in nearby wells is moderate. Reservoir Pressure • Reservoir pressure is estimated to be 3,200 psi at 8,800'ss (7.0 ppg EMW). Maximum surface pressure with gas (0.10 psi /ft) to surface is 2,320 psi.
