Attachments in Duplicate • • • To: Alaska Oil & Gas Conservation Commission From: Trevor Hyatt � by CTD Engineer Date: December 2, 2016 Re: 03-24A Sundry Approval Sundry approval is requested to plug the 03-24A liner perforations as part of the drilling and completion of the proposed 03-24A CTD sidetrack. History and current status: Well 03-24 was drilled and produced in October 1983. 03-24 was worked over in May 1994. In February 1998 a CTD sidetrack was performed to 03-24A due to gas from extensive corrosion in liner. In 2004, corroded tubing was found at surface from the CTD sidetrack liner. A calliper confirmed missing 3- 1/2" liner was missing and only cement was present in a section of the well. A workover was performed in March 2010 to repair collapsed tubing and repair TxIA communication. This well is not competitive and is ready for a sidetrack. Proposed plan: Nordic 2 Coiled Tubing Drilling rig will drill a through tubing sidetrack on or around February 15th, 2017. Nordic 2 will exit into TSGR formation above the existing 03-24A perforations. The sidetrack will target Zone 4 reserves. The proposed sidetrack is a 1,828' MD horizontal Ivishak Zone 4 producer.The lateral will be completed with a 3-1/2"x 3-1/4" x 2-7/8" 13Cr liner which will be cemented and perforated isolating the current Zone 4 perforations. This Sundry covers plugging the existing 03-24A perforations via the 03-24B liner cement job or liner top packer set post-rig (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. `"L !

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsibl 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 ` "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). i> 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. ►°► ODC9 • Date: 10/27/2016 2:1 f xs.x, ,+ wx�t6ara Oepae t : Transmittal Number: 0127 RIGHT PLACE FIRST TIME GYRODATA SURVEY TRANSMITTAL State of Alaska - AOGCC �i DATA LOGGED � �� � \O 3v2o,a Attn: Makana Bender K GENDER 333 W 7th Avenue, Suite 100 OCT 2 8 2016 Anchorage, AK 99501 AOGCC Enclosed are the materials listed below.

I have highlighted the stabilization criteria used to ev. ate this MIT-T as a "Pass" on subsequent engineering review.The initial field determination was inconclusive (color:. Yellow) because the results did meet the global BP standard of <5psi/minute for the last 15 minutes, but did n. satisfy our internal Alaska "Field Guideline" build on the old EPA 2:1 rule. The P2-09 MIT-T results were then rev.-wed by Anchorage, and were determined to be a "pass" because acceptable stabilization was demonstrated an• n conformance with both AOGCC for class-2 Injector wells and BP global internal requirements.

I have highlighted the stabilization criteria used to evaluate this MJT-T as a "Pass"on subsequent engineering review.The initial field determination was inconclusive (colored Yellow) because the results did meet the global BP standard of <5psi/minute for the last 15 minutes, but did not satisfy our internal Alaska "Field Guideline" build on the old EPA 2:1 rule. The P2-09 MIT-T results were then reviewed by Anchorage, and were determined to be a "pass" because acceptable stabilization was demonstrated and in conformance with both AOGCC for class-2 Injector wells and BP global internal requirements. z— TBG IA OA Comments 3814 -16 10 Start 3600#MIT-T at 12:41pm on 5/24/16 First 15 minutes 3742 -15 10 TBG lost 72psi Second 15 minutes 3683 -15 9 TBG lost 59 psi Third 15 minutes 3629 -16 10 TBG lost 54 psi The MIT-T results were sent to the AOGCC in support of the UIC AA,and were initially reviewed as a "pass" using the usual AOGCC stabilization criteria (for a class-2 Injector). On subsequent review by the AOGCC we were notified later by Phoebe that the MIT-T was now considered a "fail" . Thanks for reconsideration. Please let me know if you have any more questions or require additional information. Rgds Ryan BPXA MIT Acceptance Criteria Extract from the Recommended Practice for Mechanical Integrity testing dated June 30th 2016 5.2 Test Acceptance Criteria (for large volume MIT's) All well integrity testing of casing and tubing strings shall be carried out as follows: ✓ Full pressure test shall be carried out for a minimum undisturbed 30-minute monitoring period. ✓ All tests shall be recorded on a calibrated chart or an electronic data logger. This data will be used at the time to assess pass/fail criteria for the test. Data shall be retained and forwarded to the Senior Fullbore WSL for filing in the shared drive. ✓ The volume of fluid pumped and returned shall be recorded. 1 • ✓ An acceptable wellbore integrity test is as follows: > Any MIT that exhibits an overall pressure loss of less than 10% of the maximum test pressure over the entire 30-minute test period and one that meets the stabilization criteria will be defined as acceptable n ;pass. ➢ In BPXA, the stabilization criteria for an acceptable MIT shall be defined as: either • A test in which the total pressure loss in the second 15-minute test period is less than 20 psi and less than the pressure loss in the first 15-minute test period or • A test in which the total pressure loss in the second 15-minute test period is either less than or equal to half the pressure loss in the first 15-minute test period and • Note: The MIT may be extended for an additional 15-minute period to demonstrate stabilization if the pressure loss results are inconclusive. A failed MIT will therefore result from either a >10% overall pressure loss over the entire test period, or failure to meet both of the stabilization criteria. es is s owing pressure stabilization(i.e. the second 15-minute pressure loss is less than the first -minute pressure loss but fails to meet the aforementioned stabilization criteria) on the advice of the test can be classified as "Under Review" and the results can be sent to town for further V Note: All failed/inconclusive tests or pressure anomalies observed during the test shall be reviewed with the WSL before initiating further actions. ✓ Note: Tracking annuli or tubing pressure during a test will result in a failed test. 5.3 Test Acceptance Criteria(for small volume MITs) When performing MITs of small volumes of less than 5 bbls (i.e. control lines, cemented OAs, etc), the test shall be carried out as follows: ✓ A full pressure test shall be carried out for a minimum undisturbed 15-minute monitoring period. ✓ All tests shall be recorded on a calibrated chart or an electronic data logger. This data will be used at the time to assess pass/fail criteria for the test. Data shall be retained and forwarded to the Fullbore Senior WSL for filing in the shared drive. ✓ The volume of fluid pumped and returned does not need to be recorded / measured. ✓ An acceptable wellbore integrity test is as follows: — The pressure loss is less than five psi/min loss rate for 15 minutes (test duration). — The test demonstrates decreasing pressure fall-off(similar to when testing BOPs). — The test pressure shall remain above or equal to the target pressure during the test evaluation period. 2 q(ZZ-I/‘6 TREE= 4-1/16'CM/ • = P2 -09 WY NOTES: WELL REQUIRES A sssv-- vIta,u-EAO F,.. gCTUfiTOR= BAKER C KB.BE = 50.53' BF.ELB/= I __ I 1 KO-R. -------- -- ---404 a u---1 2012' 9-5/8"HES CE3ANTER Max Angle= 56° a, ti550' Datum MD= 11908' 2040' —F1/2"CAMCO BAL-0 MP,ID=3.812" [ tum TVD= 8800 SS 9-5/8"CSG,40#,L-80 BUTT-M,0=8.835" — ;:5' 11, GAS LFT MANDRELS ST MD ND CEV TYPE VLV LATCH PORT DATE IA CMT SQ7JTOC(05/09/16) — -5438' 'sir r• 1 4553 4091 43 KBG-2-LS DM' INT 0 05/11/98 I 1 0 2 11832 ;: 7 , 55 KBG-2-LS 'EMY INT 0 05/11/98 I 4 'STA#2=B a - TBG PUNCH(04/28/16) — 5987' -5992' •• 't s .41 •- - yavl v v IA TOC(12/17/15) — -5998' 1.1 I 1 111 I 1 1 1.56"TBG FIJNCH(11/18/15) — 11847' -118521 c .. 0.4 .• I 1 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. 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.

Supervisor State of Alaska Alaska Oil and Gas Conservation Commission DATE: January 15, 2001 FROM: SUBJECT: John Crisp, Petroleum Inspector Safety Valve Tests Prudhoe Bay Field Drill Site 03 January 15, 2001: I traveled to BP's Prudhoe Bay Field to witness Safety Valve System tests on DS 03. Mark Womble was BP representative in charge of testing DS 03. Testing had been canceled on DS 03 1-14-01 due to blowing snow & chill factor of-50 degrees. Testing was conducted in a safe & efficient manner. Two failures were witnessed. The AOGCC test report is attached for reference. 21 wellhouses were inspected during SVS tests. Wellhouses are in fair condition considering these were inspected after our recent blow. No heat or lights are installed in wellhouses for producing wells. SUMMARY: I witnessed SVS tests in PBU on DS 03. 21 wells, 42 components tested. 2 failures witnessed. 4.8% failure rate. 21 wellhouses inspected.
