The witness for this test was waived and the test was performed and passed on 05/19/16. Hilcorp will still implement the changes we highlighted in the previous email as we believe that it will help to improve our system but did want to send confirmation that we did have a passing test for this well and it was operated in compliance. The main error for this was in a misfiled copy of the test on our server. Thank you and sorry for any inconvenience that this has caused. If you have any questions please feel free to contact Wyatt or myself. Note that Wyatt will be out of town until next week if any questions come up.

Month SVS Test Jim, Hilcorp has identified that Endicott producer END -37 (PTD# 1950510) was recently returned to production without a current 6 month SVS test 1 r imilimir Incident Notification — Missed SVS Test — Event Date: 29 June 2016 Hilcorp Alaska, 1.1.1. Location: END 3-37, Endicott (PTS 1 25Osi0 Description: Producer END 3-37 was due for a 6 month Safety Valve System (SVS) test in May, 2016. The well had been shut in on 5/1/16 for water handling and missed pad level SVS testing that was conducted on 5/13/16. At the time of pad level testing, a tag was installed on the well's SVS panel stating that the well required a State test when returned to production. On 5/16/16, the well was put on production but a follow-up SVS test was not conducted. Normally, the tag would be removed and notification promptly made to the AOGCC for an upcoming test. In this instance, the tag was not recognized or removed. On 6/29/16 an operator identified the tag and well was confirmed to have not been tested once returned to production. What Went Right: SVS panel was correctly tagged when well missed its 180 day state test. Once missed test was recognized, it was quickly communicated to AOGCC and well was tested with all systems passed. What Went Wrong: The tag was not recognized or removed when the well was first returned to production and ultimately the well never received a valid SVS test within 5 days of return to stabilized production as per 20 AAC 25.265. What Can Be Done to Make it Right: Going forward, when a SI well misses its 180 day SVS test at Endicott, a clamshell will be installed over the wing pressure control valve. The "Needs State Test" tag will be attached to the clamshell so there is no way it can be missed when it is time to open the wing valve and bring the well online. Additionally, a white board outside of the Lead Operator's office will be used to track tagged wells in need of an SVS test. WO. fJ' ��7YM1eI �.� - reiP 9 I — 4-42 ;i>� l Po � i/ - s�.

Well names currently include a forward slash "I" followed by an obsolete bottom hole location designator. HAK would like to retain the well number as well as the "A, B, C...." sidetrack designations but remove the "/suffix". For example, "DUCK IS UNIT SDI 1-09A/L21" would become "DUCK IS UNIT SDI 1-09A". The attached spreadsheet includes original and new names for all Duck Island wells. While performing the review of Duck Island well names, HAK found a single well, "DUCK IS UNIT SDI 4-20/M35" (PTD# 1861730), that should also be modified to include an "A" label to reflect the fact that the well is a sidetrack from the original "DUCK IS UNIT SDI 4-20/T34" (PTD # 1861500). The original wellbore, abandoned 10/13/1986, was sidetracked to a new bottom hole location completed on 9/9/1987. This well appears to be one of the first sidetracks performed at Endicott. While the bottom hole code was changed, no letter was added to reflect the sidetrack. "DUCK IS UNIT SDI 4-20A" is also included on the attached spreadsheet.

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, i Mehreen Vazir BPXA, Well Integrity Coordinator • BP Exploration (Alaska) Inc.

Due to an' inadvertent oversight during training/hand-over responsibilities, these two reports are being filed later than the 30-day reporting requirements. Regarding the MIT on well 3-37/L-35, in the recent approval (No. 398-158) to convert this well from a producer to an injection service well, a condition for an MIT test was attached. As an MIT was completed (see Sundry attached here) on May 17, 1998, will AOGCC require another MIT subsequent to the conversion of the well? If there are any questions, please contact me at 564-5234.

However, an oil column was found in zone 3A and it was decided to produce out these 3A reserves prior to turning the well over to zone 2A water injection. The 3A sands have proven to be more productive than originally anticipated and it has taken approximately three years to adequately recover the 3A reserves. Recommendation With 3A production from well 3-37/L-35 dropping off and recent changes made to the 2A offtake strategy the conversion of well 3-37/L-35 to 2A water injection now appears to be the best use of the wellbore, We request that a conversion of well 3-37/L-35 from 3A production to 2A water injection be approved.

REQUEST TO CONVERT WELL 3-37/L-35 FROM PRODUCER TO INJECTION SERVICE WELL The following is a request to proceed with the conversion of well 3-37/L-35 to injection service. This well was drilled as a pre-produced 2A injector in May 1995. The well encountered oil in the 3A2 and produced 800MSTB from this sand before it was shut in for high water cut in February 1998. The original intent of this well was as a 2A injector; therefore, it is optimally placed to support updip voidage from wells 3-39AJI- 37, 4-38/K-34, and 3-03/J-33. The conversion of 3-37/L-35 to injection will optimize the current 2A waterflood by replacing 2,A injection from well 3-07/N-28 on the Northwest periphery and relocating it to a more suitable location in the central SDI. Well 3-37/L-35 was originally approved as a pre-produced injector in March 1995. At the time of approval, the associated benefits for this operation were estimated at 3.1 MMSTB of oil in the SDI 2A through improved waterflood management. Well 3-37/L-35 has been on producer status from May 1995 to the present. During this time the 2A wellset has changed considerably. Well 3-15/K-33 is no longer a 2A producer and the focus of 2A production has shifted to the northern tier of 2A wells 3-031J-33.4-38/K-34 and new infill well 3-39A/I-37. Although the previously estimated benefits of 3.1 MMSTB due to the conversion of well 3-37/L-35 to injection would be considered the high side case, enhancements in local sweep efficiency and a change in the injector/producer flux lines are expected provide an incremental increase in the ultimate recovery from this northern tier of wells. The primary benefits of increasing 2A water injection to the northern tier will be a reduction in GOR in offset wails 3-03/J-33 and 4-38/K-34. As illustrated by the time lapse CNLs in the 2B in well 4-38/K-34, significant changes in injection management strategy in de-pressurized zones are effective in mobilizing unswept oil to upstructure offtake points. In addition, 3-37/L-35 will provide pressure support for offset well 3~39A/I-37 which is currently producing at a gross fluid rate of 10,000 STB/D.

Hold pre spud meeting with crew. Drill 13-1/2" surface hole with KOP at 1700'. Use gyro for close approach until magnetic interference is past. Check with Anadrill & Gyrodata to insure they are following JORPS. Drill hole to 5092' TVD. This will put the build section and the gravels behind surface casing. Run 10-3/4" 45.5 ppf surface casing Cement surface casing. Perform top job, if necessary with 150 sx Type "E" Permafrost cement. ND diverter. NU Bop's & test. Drill out shoe and perform LOT. Perform open hole FIT 1000' below surface casing shoe. Directionally drill production hole to 10,311 TVD. Well site geologist will help pick final TD (175' below lower most possible perforation in 2A). A PDC should be picked up as the second 9-7/8" bit and drill the top 200-300' of the Tuffs. Have sample catchers and well site geologist on site before drilling the Kekiktuk. Use key seat wiper for Tuffs and HRZ. RU E/Line & run open hole logs ("Triple Combo" ). Run 7-5/8" production casing. Turbolators should be 2 per joint on the bottom 1000' of casing. If the cement job goes as planned, bond logs will not be run. Run 4-1/2" L-80 completion with hydraulic set permanent packer with WLEG 150' above the top of Kekiktuk (estimated WLEG @ 10,925' MD). ND Bop's. NU 4-1/16" 5M# tree. Set packer and test.
