Report of Sundry Well Operations Summary June 15, 2017 To Whom it May Concern: Attached please find the Sundry Application for R-22AL1: This well was CTD as a Sag only injector in early 2015. Prior to drilling the laterals, the well had an IA cement squeeze to address TxIA communication. This appeared to be effective, however, when the well was POld in August 2016, communication issues again surfaced. A LTP was set in January of 2017 to seal the suspected leak path. The well was returned to injection, however, we have continued to see IA pressure build. The well was classified as UE on 3-11-17 and, after both operational and weather delays, an LDL was run on 5/18/2017. See attached Historical - Integrity tab for recent integrity notes. Due to the success of passing MITs to liquid, this patch will not be tested via MIT, rather, it will be returned to MI service and the IA monitored for pressure buildup. The LDL confirmed a leak in a collar at 8,308'. It also noted a possible collar leak at 8,290' which is unverified due to intensity of the signal from the deeper leak. Due to the lack of confirmation of the leaks at the higher location(s), a patch covering the entire interval is desired. Sincerely, BP Exploration (Alaska) Inc. P.O.

Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a: Classification of Service Wells: Gas Injection,Water Injection,Water-Alternating-Gas Injection,Salt Water Disposal,Water Supply for Injection, Observation,or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13. The API number reported to AOGCC must be 14 digits(ex. 50-029-20123-00-00). Item 20. Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval(multiple completion),so state in item 1,and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation. Flowing,Gas Lift,Rod Pump,Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain). Item 28: Provide a listing of intervals cored and the corresponding formations,and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071. Item 30: Provide a listing of intervals tested and the corresponding formation,and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 AAC 25.071.

This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the AOGCC reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the AOGCC specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

The R-22A sidetrack will exit the existing 7" liner and kick off in the SAG, land and invert in the Shublik, and re-enter the SAG. Once in the SAG, run and cement a 3-1/4" L-80 liner as a protection string. After cementing, mill out shoe track and drill R-22A southeast to TD. R- 22A sidetrack will be completed with a 2-3/8" Slotted L-80 liner with a flow-thru billet as the liner top and set in open hole. R-22AL1 will kick off the 2-3/8" flow-thru billet and drill to northewest to TD. R-22AL1 will be completed with a 2-3/8" slotted, L-80 liner with the liner top set in the cemented 3-1/4" liner.

Attachments: R-22A PTD 10-16-14.doc Steve, First, it looks like I mixed my numbers for reservoir pressure. The correct reservoir pressure is 3,432 psi (mixed up the 4 and the 3). However, my MASP number(2552psi) is still the same since I carried the correct number forward in my calculations. MASP Explanation:The RKB you refer to in your calculation is not the RKB of the Nordic Rigs in CTD. In CTD,we tie into the parent surveys. So the RKB we report is the RKB of the parent, not the rig. We decided as a group to use TVD at sea level to calculate MASP in order to simplify calculations and report the worst case scenario with gas to surface. Here is how I calculated MASP. 8800'TVD*7.5ppg*0.052= 3432 psi MASP=3432psi-(0.1psi/ft)(8800')= 2552psi We will not pre-produce this well,just flow back to clean up slotted liner. Attached is the new PTD with the corrected reservoir pressure.Thank you for questions and please let me know if you any more questions.Thank you.

Travis, Along with the questions below, could you also tell me: will PBU R-22A be pre-produced for an extended period, or will the well simply be flowed back to clean up the slotted liner?

From: Davies, Stephen F (DOA) Sent: Wednesday, October 15, 2014 11:27 AM To: 'travis.boltz@bp.com' Subject: FW: R-22A/AL1 Directional Plan Joe,Travis: For PBU R-22,why does the ground level elevation on the Permit to Drill form (38.13')differ from the elevation in the directional survey plan (32.44')? Which is correct? Also,the reservoir pressure and MASP calculations seem to be a bit off(3342 psi at 8800'TVDSS is equivalent to 3342 psi at 8875'TVD; and 3342/8875=0.3766 psi/ft; so, 0.3766 psi/ft * 19.27 conversion factor=7.26 ppg equivalent. After subtracting the assumed 0.10 psi/ft gas gradient: 0.2766 psi/ft * 8875'TVD= 2455 psi MASP at rig-floor level). Or am I wrong? (Remember, I'm just a geologist.)

In accordance with 20 AAC 25.005(f), all records, data and logs acquired for the pilot hole must be clearly differentiated in both well name Pilot Hole ( PH) and API number (50- - - - ) from records, data and logs acquired for well (name on permit). The permit is approved subject to full compliance with 20 AAC 25.055. Approval to produce / inject is contingent upon issuance of a Spacing Exception conservation order approving a spacing exception. (Company Name) Operator assumes the liability of any protest to the spacing exception that may occur. All dry ditch sample sets submitted to the AOGCC must be in no greater Dry Ditch Sample than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones. Please note the following special condition of this permit: Production or production testing of coal bed methane is not allowed for Non-Conventional (name of well) until after (Company Name) has designed and Well implemented a water well testing program to provide baseline data on water quality and quantity. (Company Name) must contact the AOGCC to obtain advance approval of such water well testing program. Regulation 20 AAC 25.071(a) authorizes the AOGCC to specify types of well logs to be run.
