Shortly thereafter (Nov 2006), the well was secured with a tubing tail plug below the packer. An MIT - OA with N2 in Jan 2009 confirmed the presence of a 1/8" hole at the 2 -o'clock position roughly 2" below the conductor flutes. Although the conductor by surface casing annulus was cemented up to -14" from the flutes, bubbling 360 degrees around the tree under low annulus pressure suggests other surface casing leaks further down hole. An OA down squeeze (Sundry #319-097) was attempted on 4/26/19 but was not completed due to lack of injectivity into the OA. Pumped -1.8 bbls of crude down the OA and reached a pressure of 1100 psi. The well is currently classified as Not Operable due to the surface casing leak. Last MIT -T 5/12/2011, passed to 2500 psi. Last CMIT-TAA 4/26/2019, passed to 2684 psi. Objective The objective of this procedure is to place cement plugs across and above the reservoir zone as well as the upper wellbore to permanently abandon the well. ✓ DPZ1 = 1974 ft and - 8407 ft and DPZ3 = 10987 ft and - (Did not see base of DPZ 3) Procedural Steps Special Projects 1.

Shortly thereafter (November 2006), the well was secured with a tubing -tail plug below the packer. An MIT -OA with nitrogen in January 2009 confirmed the presence of an 1/8" hole at the 2 -o'clock position roughly 2" below the centralizing conductor flute. Although the conductor x SC annulus was cemented up to 14" from the flutes, bubbling 360 degrees around the tree under low conductor pressure suggests other SC leaks further down hole. Because 16-28 is in the vicinity of the 2019 Seismic Program, there is potential that the well may have sidetrack potential for a periphery oil play. Current Status The well is currently classified as Not Operable by BP due the surface casing leak. The well is secured downhole and has been shut-in since late 2005. Objective In order to reduce possible risks associated with surface casing leaks to the conductor, the OA will ' be cemented to surface with a downsqueeze cement job. Procedural stepl Q.. C M. t li ' r v Z706 +C- Z 5-50 �s `. C Special Projects 1. Steam clean the Conductor x Surface Casing Annulus to top of good cement. 2. Circulate cement into the conductor from the top of existing cement until clean cement returns are observed. Fullbore 3. WOC from conductor job at least 3 days. Establish injectivity rate and pressure with diesel or crude down the OA and into formation. Perform a step -rate injection test and record pump pressure and rate at several different pump rates. Max OA pressure 2500 psi. a. Make certain to monitor the cellar and conductor for returns while pumping down the OA. b. Have a vac truck on location and prepared to pump out of the cellar in case of returns to surface. Special Projects / Fullbore 4. RU Cementers to the OA. RU in such a way that the OA can be closed in and wash-up water diverted upstream of the OA. Mix cement on the fly. Pump the following schedule at maximum rate below 2500 psi treating pressure. 1. 10 bbls of 60/40 or neat McOH 2. 165 bbls hot surfactant wash (180°F freshwater + 2 gal/mgal F103 + 2 gal/mgal U067) 3. 10 bbls of 13.5 ppg MUDPUSH II Spacer 16-28 OA Down -Squeeze: 2/22/2018 TTS 4. 20 bbls of neat 15.8 ppg Class G cement 5. 50 bbls of 15.8 ppg Class G with 15 -ppb aggregate 6. 125 bbls of neat 15.8 ppg Class G cement 5. Pump no displacement behind cement. Slow rate to approximately 1 bpm when aggregate reaches the casing shoe (-185 bbls of cement away / 10 bbls cement remaining to pump). a. With 3-5 bbls of cement left to pump: Swap to take returns from upstream of the OA while still on cement (S/D pumping as needed). Be sure to swap away from the OA and direct returns to surface before the last of the cement is pumped downhole to ensure only cement goes down the OA. b. SI the OA and flush lines only to surface, without pumping down the OA. Note that the OA may be on a vacuum and may suck any wash water that is pumped across the OA down into the OA if allowed to do so. Note: Good success on OA down -squeezes has been realized by the hesitation squeeze method; i.e. shutting down pump entirely as the last -10 bbls of cement are pumped, watching to see if pressure is maintained or drops right off then pumping a couple more barrels until catching fluid and repeating this to give the aggregate every opportunity to bridge off either in the OA or at the shoe. See WSRs from X-34, Y-39, and L1-13 for reference. 6. After washing up surface lines, hold an open bleed on OA for 1 hour, sniff for LEL's, then remove OA gate valve and manually clean any residual cement from the valve and VR profile.

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.

P O Box 100360 PRB 24 Anchorage, AK 99510-0360 Re: No-Flow Verification PBU Wells DS 16-28 & 17-14 Gentlemen: Recently our inspector John Spaulding witnessed three "no-flow" tests on PBU Wells: DS 16V28, 17-9, & 17-14. The gas-lift gas On the three wells had been shut-off 24 hours before the test. Also, the annuli had been bled down before our inspector arrived. The Inspectors observed flow into an open top tank for a period of one to three hours and gas rates were measured with an American AL 425 gas meter. Well No. Test Date Fluid Rate Gas Rate Comments 200 scf/hr max press inc. 14.5 psi 7 ~ DS~6-28 5/30/95 minor Well passed the no-flow %est DS 17-14 6/19/95 minor 240 scf/hr gas rate steady Well passed the no-flow test DS 17-9 6/19/95 not 'noted 90-1300 scf/hr During the period the inspector was there taking liquid and gas measurements at 30 minute intervals, the gas rate increased from 90 to 1300 scf/hr, therefore, this well did not pass the no-flow test.. Wells DS 6-28 and DS 17-14 meet the criteria of a "no-flow" performance test and, as such, are considered incapable of unassisted flow to the surface. Under the authority of Conservation Order 341, Rule 5, they are not required.to have a fail safe automatic SSSV, however, the pilot and surface safety valve must be maintained in good condition, and if for any reason, the well again becomes capable of unassisted flow of hydrocarbons, the subsurface safety valve must be reinstalled and maintained in good working condition.

The test started at 1:30 pm and lasted for approximately 3 hours. A-n American AL 425 gas meter was used to measure gas flow and a 40 bbl. open top tank was used to measure any possible liquid flow. The gas lift was shut in 24 hours prior to the test and the well was bled down through the de-pressured test seperator. Upon my arrival the well had been shut-in for approximately 12 hours, and had pressured up to 750 psi. The well was opened up to the open top tank and the well bore immediately bled down to a positive pressure of 2 psi guage in 15 minutes. At this point monitoring gas flow with the American AL 425 gas meter began. Over the 3 hour period a maximum of 200 scf/hour was and a maximum of 14.5 psi buildup was observed. The testing indicated that the "No Flow" test was well within the acceptable limits of the AOGCC guidlines.

Shortly thereafter (November 2006), the well was secured with a tubing -tail plug below the packer. An MIT -OA with nitrogen in January 2009 confirmed the presence of an 1/8" hole at the 2 -o'clock position roughly 2" below the centralizing conductor flute. Although the conductor x SC annulus was cemented up to 14" from the flutes, bubbling 360 degrees around the tree under low conductor pressure suggests other SC leaks further down hole. Because 16-28 is in the vicinity of the 2019 Seismic Program, there is potential that the well may have sidetrack potential for a periphery oil play. Current Status The well is currently classified as Not Operable by BP due the surface casing leak. The well is secured downhole and has been shut-in since late 2005. Objective In order to reduce possible risks associated with surface casing leaks to the conductor, the OA will ' be cemented to surface with a downsqueeze cement job. Procedural stepl Q.. C M. t li ' r v Z706 +C- Z 5-50 �s `. C Special Projects 1. Steam clean the Conductor x Surface Casing Annulus to top of good cement. 2. Circulate cement into the conductor from the top of existing cement until clean cement returns are observed. Fullbore 3. WOC from conductor job at least 3 days. Establish injectivity rate and pressure with diesel or crude down the OA and into formation. Perform a step -rate injection test and record pump pressure and rate at several different pump rates. Max OA pressure 2500 psi. a. Make certain to monitor the cellar and conductor for returns while pumping down the OA. b. Have a vac truck on location and prepared to pump out of the cellar in case of returns to surface. Special Projects / Fullbore 4. RU Cementers to the OA. RU in such a way that the OA can be closed in and wash-up water diverted upstream of the OA. Mix cement on the fly. Pump the following schedule at maximum rate below 2500 psi treating pressure. 1. 10 bbls of 60/40 or neat McOH 2. 165 bbls hot surfactant wash (180°F freshwater + 2 gal/mgal F103 + 2 gal/mgal U067) 3. 10 bbls of 13.5 ppg MUDPUSH II Spacer 16-28 OA Down -Squeeze: 2/22/2018 TTS 4. 20 bbls of neat 15.8 ppg Class G cement 5. 50 bbls of 15.8 ppg Class G with 15 -ppb aggregate 6. 125 bbls of neat 15.8 ppg Class G cement 5. Pump no displacement behind cement. Slow rate to approximately 1 bpm when aggregate reaches the casing shoe (-185 bbls of cement away / 10 bbls cement remaining to pump). a. With 3-5 bbls of cement left to pump: Swap to take returns from upstream of the OA while still on cement (S/D pumping as needed). Be sure to swap away from the OA and direct returns to surface before the last of the cement is pumped downhole to ensure only cement goes down the OA. b. SI the OA and flush lines only to surface, without pumping down the OA. Note that the OA may be on a vacuum and may suck any wash water that is pumped across the OA down into the OA if allowed to do so. Note: Good success on OA down -squeezes has been realized by the hesitation squeeze method; i.e. shutting down pump entirely as the last -10 bbls of cement are pumped, watching to see if pressure is maintained or drops right off then pumping a couple more barrels until catching fluid and repeating this to give the aggregate every opportunity to bridge off either in the OA or at the shoe. See WSRs from X-34, Y-39, and L1-13 for reference. 6. After washing up surface lines, hold an open bleed on OA for 1 hour, sniff for LEL's, then remove OA gate valve and manually clean any residual cement from the valve and VR profile.
