Reports of Sundry Well Operations Summary for wells N-01A and N-27 October 26, 2017 To Whom It May Concern: Please find attached the Reports of Sundry Well Operations for Channel Squeeze and Addition of Perforations for Wells N-01A (PTD # 204-113) and N-27 (PTD # 207-104). On August 31, 2017, the State received an additional request for Sundry Approval for each of the wells listed above. The purpose of this additional Sundry was to obtain current and valid Sundries for conversion to WAG injection. At that time, the wells were expected to be put on injection (P01) in September 2017 and after passing MITs a Report of Sundry Well Operations would have been submitted for both active Sundries; however, due to unforeseen facility work the wells have been unable to be POI. At this time, please find attached the Report of Sundry Well Operations for the well work portion only, referencing Sundries 317-024 and 317- 059 for N-01A and N-27 respectively. Additional Reports of Sundry Well Operations, referencing Sundries 317-422 and 317-423 for N-01A and N-27 respectively, will be submitted upon completion of a State witnessed Mechanical Integrity Test.

This AOR discusses wells within 1/4 mile of each well's entry point into the Sag River formation. Current Status: N-01A is currently an operable producer. The last well test on 09/08/2015 indicated 607 bopd, 61%watercut, and 20,722 scf/bbl GOR. N-27 is currently an operable producer. The last well test on 10/09/2015 was 584 bopd, 29%watercut, and 36,729 scf/bbl GOR. Both of these wells were initially scheduled to be converted to WAG injectors in 4Q 2015 as part of the N-pad UZI (Updip Zone 4 Injection) Project, prior to that work beginning sundries for conversion were approved on 06/19/2015 (315-330 and 315-332). The UZI Project targets remaining oil where the gas cap has expanded into zone 4, and the gravity drainage process is less efficient. The UZI Project achieves improved recovery through pattern injection of water and/or MI. The area of UZI potential is generally identified as immediately upstructure of the existing WF/EOR area. The planned facility work to install MI and water injection headers was completed slightly behind schedule, and one of the three conversion wells, N-07A, was put on injection July 10, 2016. Due to conformance issues with N-01A and N-27, the wells were not ready to be put on injection until recently. Since more than 12 months lapsed between the initial sundry approvals and the completion of the well work, these wells have not been put on injection until a new sundry for conversion is approved. N-01 A N-01A Completion: N-01 A is a conventional (max angle is 68°) well that was sidetracked in September 2004 in zone 4. It was sidetracked with future UZI injection potential in Z4 as part of that justification. The well was pre-produced between 09/2004 and 09/2015, while waiting for approval and construction of the UZI project. The well has been SI and disconnected • from the production system since 09/29/2015. N-01A is completed with 4-1/2", L-80 tubing and production liner (wellbore schematic Figure 1). The original well was drilled in 1970 and it was sidetracked in 2004. A CBL shows that the cement behind the original 9-5/8" casing was poor. However during the sidetrack in 2004, a new 7" liner was installed from 8,968'MD to 7181' MD' with a 7" scab liner cemented in place from 7181' to 2426'MD. The liner was cemented with 35 bbls of • 15.8 ppg Class G cement. The estimated TOC is 7,884'MD. There are no cement bond logs for this section of pipe, but no abnormalities occurred with this cement job. 4-1/2" tubing was installed from surface to TD @ 9748'MD. It was cemented with 27 bbls of 15.8 ppg Class G cement. No abnormalities occurred with this cement job although—15 bbls were circulated back to surface. After the initial sundry for conversion was approved in 2015 (315-330), a caliper was run on January 13, 2016, indicating that there was corrosion across the L-80 production liner. On February 24, 2016, a borax/RPM log was run. The log indicated channeling across / the proposed perforation interval. A remedial cement squeeze (sundry 317-024) was attempted on June 22, 2017. As part of the approved program, coil tubing attempted to first mill a restriction at 9185' MD, milling was unsuccessful and no more progress was made past 9202' MD, at this point the squeeze was cancelled and the coil tubing unit rigged down off the well. On 15 July, 2017, slickline drifted the well with a variety of tool strings, and confirmed that we do not have access to the wellbore below 9202' MD. There is a potential hole in the liner at 9185' MD, this depth is located in the 46P,just below the Shublik Shale, within the Ivishak formation. It is planned to operate N-01A as a WAG injector, we believe it to be suitable based on the most recent integrity tests, which are: 01/14/2016: MIT-IA Passed to 4000 psi 12/22/2012: MIT-T to 2,500 psi passed (plug @ 8,807'MD) 01/29/2004: MIT-OA to 2,500 psi - passed N-01A Area of Review The wells within 'A mile of N-01 A are listed in the table below (Map showing wells within 0.25 mi radius from N-01A figure 3). The measurements were made at the closest points between the wells within the Prudhoe Oil Pool. Three individual wells (including • the N-01 parent) enter the AOR and the tables below summarize conditions.

The cement was poor quality in most places- however there was a good section (50') of cement existing (between 8,660- 8,710), combined with production history that had no evidence of barium scaling (which would be indicative of communication with the Cretaceous).

N-27 N-27 Completion: N-27 is a conventional (max angle is 26°) well that was rotary drilled and completed in November 2007 in zones 3 & 4. It was drilled with future UZI injection potential in Z4 as part of that justification. The well was pre-produced between 12/2007 and 10/2015, while waiting for approval and construction of the UZI project. The well has been SI and disconnected from the production system since 10/31/2015. N-27 is completed with 4-1/2", 13-Cr tubing and 4-1/2", L-80 liner (wellbore schematic Figure 2). When the well was drilled and completed in 2007, a 4-1/2" L-80 liner was run from 8,795 to 9,503'MD and cemented with 24 bbls of Class G cement. The 7" casing was run from 26' to 8,967'MD and cemented with 132 bbls of 12 ppg Lite Crete and 38 bbls of 15.8 ppg Class G. A CBL was run on September 12, 2007 in the 7" casing and it indicated an adequate cement bond with the TOC at 6,350'MD. A subsequent CBL run on November 28, 2007 showed a good to poor cement bond in the production liner. After the initial sundry was approved in 2015 (315-332), a caliper was run on January 12, 2016, indicating that there was corrosion across the L-80 liner. On June 28, 2016, a borax/RPM log was run. The log indicated channeling across the proposed perforation interval. A remedial cement squeeze (sundry 317-057) was performed on June 28, 2017. On 14 July, 2017, a subsequent borax log indicated that we had successfully fixed the channeling, and now have the desired conformance in upper zone 4. It is planned to operate N-27 as a WAG injector, we believe it to be suitable based on the most recent integrity tests, which are: • 06/23/2017: MIT-T Passed to 2590 psi 01/14/2016: MIT-IA Passed to 4000 psi 07/09/2011: MIT-OA to 1200 psi passed N-27 Area of Review The wells within 1/4 mile of N-27 are listed in the table below (Map showing wells within 0.25 mi radius from N-27 figure 3).

Lower rate to -1.0 bpm (or whatever injectivity is at 1600 psi) and log one baseline pass at 20 fpm followed by a repeat baseline pass at 60 fpm over interval 9420'-9000' MD. 15. Pump -100 bbls of borax followed by 1% KCI at -5.0 bpm. 16.After injecting 30 bbls of borax into the formation, lower rate to -1.0 bpm (or whatever injectivity is at 1600 psi) and log a borax pass at 60 fpm over interval 9420'-9000' MD. 17. RBIH to 9420' MD and increase pump rate such that 60 bbls has been displaced into the perfs Page I2of7 when toolstring is at the bottom interval. 18.After injecting 60 bbls of borax into the formation, lower rate to 1.0 bpm and log a repeat borax pass at 60 fpm over the same interval. Volume from TD to top of interval is -5 bbls. This leaves over 35 bbls of extra borax to perform the last pass. 19. Pump an additional 280 bbls of 1% KCI to flush the borax from the near wellbore. 20. Freeze protect well with 38 bbls of diesel. Page I 3 of 7 • • APPENDIX A: CT Operation for N-01 From: Josh Allely— Intervention Engineer Contact: 907-350-7362 Notes: • The objective of this procedure is to perform a channel squeeze so that the "UZI" perfs can have hydraulic isolation from the Z4 perfs. • Given the poor condition of the liner, this job is designed as a block squeeze through a cement retainer to help keep the cement in place. This will increase the odds of success even if a true "squeeze" is not obtained. • This job is designed as a "two stage" cement job (though the cement will all be pumped at the same time) where the mircofine cement will be pumped first to try and fill the channels with cement, followed by class G to create perf nodes and trap the FineCem cement in the channel. Cement Design (FineCem Cement): BHST—220 deg F. SBHP—3250 psi. BHCT—220 deg F Cement: FineCem. Batch mixed with onsite QC. Density: 13 ppg Thickening time: 7-10 hours API Fluid Loss: 5-15 cc Free Water: 0 Compressive Strength: Minimum of 2000 psi Requested Volume: 20 bbls - The slurry should be smooth and homogenous. - There should be no free water or gelation of the slurry. Cement Design (Class G): BHST—220 deg F. SBHP — 3250 psi. BHCT— 200 deg F Cement: Class G cement. Batch mixed with onsite QC. Density: 15.8 ppg Thickening time: 7-10 hrs. API Fluid Loss: 160-240 cc. (80-120 cc/30 min TEST) Free Water: 0 Filter Cake: 0.75"-1.0" Compressive Strength: Minimum of 2000 psi Requested Volume: 20 bbls - The ratio of cake thickness to filtrate volume should be consistent with lab results. - The filter cake should be firm and dry. - The slurry should be smooth and homogenous. - There should u d be no free water or gelation of the slurry.

MIRU CT. Mill Liner Restrictions. 2. MU and RIH with a 3.70" flat bottom opti-cut (or similar mill suitable for milling through metal). Mill should have no side cutting structure as it will be easy to sidetrack given the condition of the liner. a. Based on the caliper, the restrictions appear to be metal liner damage. b. If the mill is short, a stringreamer should be placed above the mill, below the motor to help prevent sidetracking c. Place a stabilizer above the motor to help keep BHA as straight as possible. 3. Mill liner restrictions to a TD of—9440 CTMD. It is not expected that a hard bottom will be reached as the well has sand at this depth and we are not requesting an FCO for this operation. Returns can be taken to formation for the entire job. GR/CCL Log 4. MU and RIH with a memory GR/CCL in a carrier with a suitable drift for a HES composite cement retainer(OD —3.66"). 5. Drift to TD and log from TD to 8400' MD. Flag pipe for perfs at 9255'-9260' MD and composite retainer at 9150' MD. Ad Perf/Composite Cement Retainer 6. MU and RIH with 5' of 6 spf HES guns. 7. Shoot pert interval of 9255'-9260' MD (see attached pert form for gun specs). 8. MU and RIH with HES composite cement retainer and set at 9150' ELMD. 9. While POOH, keep hole full down the backside by pumping 60/40 methanol. 10. At surface, perform a MIT-T to 1500 psi to ensure retainer is set and holding. If injection can be established into the reservoir, contact town for plan forward. Cement Liner 11. MU and RIH with cement retainer stinger(no check valves). 12. Well should be a closed system so returns will need to be taken from the backside while RIH. Page 15 of 7 4110 • 13. RIH and sting into retainer at 9150' ELMD. 14. Establish injectivity into the formation by pumping down the CT. 15. Pressure up the backside to verify no communication with the CT. 16. Batch mix 20 bbls of FineCem cement and 20 bbls of class G cement. 17. After cement passes QC, pump the following schedule down CT: a. Freshwater spacer. b. 20 bbls of FineCem c. 20 bbls of class G cement. d. Displacement fluid. 18. Downsqueeze cement into the formation until a squeeze is achieved, defined by 2000 psi of CT pressure at minimal pump rate, or until 1 bbls of cement remains in the CT (do not overdisplace cement). 19. Unsting from retainer and lay in 1:1 the remaining cement above the retainer. This cement will immediately be contaminated so it is not necessary to get any cement above the BHA; PUH keeping cement below the BHA. 20. PUH to safety and prepare to reverse out cement. 21. Reverse out cement to 10' above the retainer pumping slick 1% KCI down the backside and up the CT. 22. POOH and FP well to 2500' MD. Wait on cement to reach 500 psi compressive strength. 23. MU and RIH with a 3.700" OD motor/mill assembly. 24. Tag TOC and correct depth to 9140' ELMD. This is the cement retainer set depth minus the 10' of cement placed on top. Verify these depths in the previous CT WSR report. 25. Mill cement down to 9460' ELMD using Powervis and 1% slick KCL. a. If losses become unmanageable, cut clean out short and chase returns as best as possible. 26. POOH chasing returns at 80%. 27. At surface, perform a pressure test of the cement squeeze with 60/40. Pressure up to 2500 psi and watch fall-off for 30 minutes recording data in AWGRS every 5 minutes. If unable to achieve 2500 psi, record injectivity at 1.0 bpm for—5 minutes.

This log was run to assess the condition of the tubing and liner logged with respect to corrosive and mechanical damage. The caliper recordings indicate the 4 5 inch tubing appears to be in good condition with respect to corrosive and mechanical damage,with no significant wall penetrations,areas of cross-sectional wall loss,or ID restrictions recorded. The caliper recordings indicate the 4 5 inch liner logged appears to be in poor condition with respect to corrosive and mechanical damage Wall penetrations ranging from 41%to 100%wall thickness are recorded throughout the liner logged. Recorded damage appears in the forms of multiple holes and line corrosion. Thirty-five percent cross-sectional wall loss is recorded in a hole in joint 219(9,327 feet) Heavy deposits are recorded in joint 216,restricting the I D to 3.17 inches at 9,185 feet. A graph illustrating minimum diameters on a joint-by-joint basis of the tubing and liner logged is included in this report. The body region analysis and joint tabulation sheets for the 4 5 inch tubing and liner are combined in this report. This is the second time a PDS caliper has been run in this well and the first time the 4,5 inch tubing and liner have been logged.

This AOR discusses wells within 1/4 mile of each well's entry point into the Sag River formation. Current Status: N-01 A is currently an operable producer. The last well test on 05/02/2015 indicated 590 bopd, 57% watercut, and 21,281 scf/bbl GOR. N-07A is currently an operable producer. The last well test on 10/06/2013 indicated 0 bopd, 100%watercut. N-27 is currently an operable producer. The last well test on 04/26/2015 was 655 bopd, 28% watercut, and 33,962 scf/bbl GOR. All three of these wells are scheduled to be converted to WAG injectors in 2015 as part of the N-pad UZI (Updip Zone 4 Injection) Project. The UZI Project targets remaining oil where the gas cap has expanded into zone 4, and the gravity drainage process is less efficient. The UZI Project achieves improved recovery through pattern injection of water and/or MI. The area of UZI potential is generally identified as immediately upstructure of the existing WF/EOR area. If planned facility work to install MI and water injection headers is completed as scheduled, N-07A will be ready for injection as early as Q3 and N-01 A and N-27 in Q4 2015. N-01 A pf74,0 erhQ'Y Oil /Iegio7 for N-01A Completion: Con c if. GP y Cer ye,-t,''', ry f we//. �/, - 6'/�,j N-01 A is a conventional (max angle is 68°) well that was sidetracked in September 2004 in zone 4. It was side-tracked with future UZI injection potential in Z4. It is currently being pre-produced while waiting for approval and construction of the UZI project. N-01A is completed with 4-1/2", L-80 tubing (wellbore schematic Figure 1). To convert it to an injector, a plug will be set above the existing zone 4 perforations to ensure zonal isolation and new perforations will be shot in the bypassed oil lens in zone 4. - The original well was drilled in 1970 and it was sidetracked in 2004. A CBL shows that the cement behind the waspoor.original 9-5/8" casingHowever duringthe sidetrack in g 2004, a new 7" liner was installed from 8,968'MD to 7181' MD' with a 7" scab liner cemented in place from 7181' to 2426'MD. The liner was cemented with 35 bbls of 15.8 ppg Class G cement. The estimated TOC is 7,884'MD. There are no cement bond logs for this section of pipe, but no abnormalities occurred with this cement job. 4-1/2" tubing was installed from surface to TD @ 9748'MD. It was cemented with 27 bbls of 15.8 ppg Class G cement. No abnormalities occurred with this cement job although—15 bbls were circulated back to surface. Operation of N-01A as a WAG injector is not seen as an issue as long as the well passes - an MIT-IA.

The cement was poor quality in most places - however there was a good section (50') of cement existing (between 8,660- 8,710), combined with production history that had no evidence of barium scaling (which would be indicative of communication with the Cretaceous). These factors indicate zonal isolation. N-14B- 50-029-20594-70 1230 . Only plugback is in AOR & it was cemented.

N-07A N-07A Completion: N-07A is a conventional (max angle is 66°) well that was sidetracked in July 2004 in zone 2B and 2C. It was side-tracked with future UZI injection potential in Z4, and was pre-produced while waiting for approval of the UZI project. N-07A was online as a producer from 2004 until 2013 when it reached high GOR. An unsuccessful squeeze was attempted in mid-2013 and the well has been offline since. N-07A is completed with 4-1/2", 13-Cr tubing & 4-1/2", L-80 liner(wellbore schematic Figure 2). To convert it to an injector, a plug will be set above the zone 2 perforations to ensure zonal isolation and new perforations will be shot in the bypassed oil lens in zone 4. The original well was drilled in 1974 and it was sidetracked in 2004. CBL's were run in 1974 and 1985. Both confirmed good cement for the 9-5/8" casing above 10,150'MD, with the TOC above 9,650'MD. The 9-5/8" casing was cemented with 1270 sacks of Howco Light cement and 41 bbls of Class G cement. As part of the July 2004 sidetrack, a 7" scab liner was installed from surface to 8,921' MD. This was cemented with 106 bbls of 12.5 ppg Litecrete followed by 57 bbls of 15.8 ppg Class G cement. A 4-1/2" L-80 liner was run from 9,826' to 10,832'MD and cemented with 27 bbls of 15.8 ppg Class G cement. No cement bond logs were run in the liner as the tubing wasn't pulled. However a Borax log to look for channeling was run in 2006 and it indicated some channeling around the current perforations only. Operation of N-07A as a WAG injector is not seen as an issue as long as the well passes an MIT-IA.

However the casing and parent wellbore is outside the AOR. Only the liner of N-20A sidetrack is in the AOR. There are no CBL's or Borax logs to show quality of cement in liner- however after 11 years of production, the well is still competitive and there's no communication with the GOC in the heel. This means that the —2000' of cement(based on volumes pumped) above top perfs provides isolation from the heel (and thus parent well).

N-27 N-27 Completion: N-27 is a conventional (max angle is 26°) well that was rotary drilled and completed in November 2007 in zones 3 & 4. It was drilled with future UZI injection potential in Z4 and was pre-produced while waiting for approval of the UZI project. N-27 is completed with 4-1/2", 13-Cr tubing and 4-1/2", L-80 liner(wellbore schematic Figure 3). To convert it to an injector, the wireline retrievable plug (set in 2008 to isolate water in zone 3 perfs) will be pulled if possible, a new plug will be set above the existing zone 4 perforations (to ensure zonal isolation) and new perforations will be shot in the bypassed oil lens in zone 4. When the well was drilled and completed in 2007, a 4-1/2" L-80 liner was run from 8,795 to 9,503'MD and cemented with 24 bbls of Class G cement. The 7" casing was run from 26' to 8,967'MD and cemented with 132 bbls of 12 ppg Lite Crete and 38 bbls of 15.8 ppg Class G. A CBL was run on September 12, 2007 in the 7"casing and it indicated an adequate cement bond with the TOC at 6,350'MD. A subsequent CBL run on November 28, 2007 showed a good cement bond in the liner. Operation of N-27 as a WAG injector is not seen as an issue as long as the well passes an MIT-IA.

Why were these specific wells chosen for conversion? BP has had the idea for an UZI project in development for 8+years. There is oil stranded on the shale lenses that these injectors would sweep towards producers surrounding them. To complete this project,we've drilled new injectors(N-28& N-29) and are in the process of installing an MI and PW header to tie-in the converted producers&new injectors. The UZI injection on N-pad (including N-01A, N- 07A, N-27, N-28 &N-29)is meant to cover most of N-pad, particularly the areas where lenses have been seen in surrounding wells. The UZI reserves model indicates that the incremental reserves recovered by converting N-27&N-01A(and losing current production)are greater than if we leave them as producers. N- 27 well was drilled as a future injector-we just pre-produced it while waiting for the UZI project to materialize. N-01A was side-tracked earlier than N-27, but its secondary objective was to maintain options for UZI injection. The UZI project has been sanctioned by partners and has been included in the GPB IPA Plan of Development for the last few years.
