No permits were issued and no formal folder of record (information) created. Information known to the Commission through other agencies, journals, reports, news or additional historical means has been collected and entered into a database of Well History information. If specific information exists, these pages may be filed in this folder. Occasionally, the information has been obtained from a report that may deal with a general area and many wells. If or when possible, we may be able to 'point' the person interested in this specific well to one or more of these information sources. However, at best, this will be incomplete and independent research should be conducted to locate, if available, further information about a particular well site. • MEMORANDUM State of Alaska Alaska Oil and Gas Conservation Commission TO: Jim Regg DATE: 4/28/16 P. I. Supervisor A.ANNED SEP 2 6 2016, FROM: Guy Cook SUBJECT: Abandonment Petroleum Inspector Iko Bay#1 Bureau of Land Management PTD 100-136; Sundry 316-122 4/24/16: I traveled to the IKO Bay#1 well location by flying into Barrow from Deadhorse and then riding in a Steiger tractor approximately thirty miles out to the cat-train camp. After getting the walk-through of the camp I went to the well-site and met with Joe McInnis with the BLM and Mike Grubb with Solsten. We discussed the well and the previous operations they had completed. We also discussed their plan forward and their ideas on how to accomplish their goals for the well. Prior to my arrival they had perforated the tubing at approximately 900 ft to attempt to circulate from the tubing up the tubing-casing annulus (IA). The circulation attempts were unsuccessful. They believed the cause of this was hydrates close to the surface in the IA. They had set a bridge plug in the tubing at approximately 700 feet which included all the areas they thought had hydrates. They had brought a 4 1/6" annular preventer from Kenai and planned to rig it up to the well. They would pressure test it with a 1" test joint so they could circulate hot 9.8ppg brine down the 1" workstring and up the tubing-workstring annulus to thaw the ice they believed was in IA. This would hopefully give them back circulation from the tubing to the backside. By the end of the day they had installed the annular onto the well. They would come back in the morning to further prepare to circulate the heated brine. 4/25/16: After tightening up the bolts to the annular and running the hardline and hoses to circulate the hot brine, we tested the BOPE. The annular, choke and associated equipment were tested to 50 psi low and 1500 psi high. The annular failed the initial test, but passed the retest with no bleed off. The first test was the only failure during the testing period. After running in the hole with the 1" workstring was completed, the crew began circulating heated 9.8ppg brine down the 1" pipe and up the tubing-worstring annulus. The circulating was continued throughout the night. In the morning the returning fluid was coming back at temperatures ranging from 48 F to 80 F. The fluid they were pumping into the well was at 130 F. The backside was producing a small amount of gas, approximately 50 psi, during this process and was being bled to zero every 30 minutes. They had pumped 31/2 gallons 2016-0427_Abandon IkoBay-l_gc.docx Page l of 9 .?' r SEP 2 6 zags • of methanol previously and they recovered about a 1 1/2 gallons of that back during this time as well. It was decided by town to up the rate they were pumping from a '/ bbl/minute to at least a '/2 bbl/minute so the temperature on the returns would improve. They had started pumping the brine at 7 pm the night before, so at this time they had been pumping 12 hours. 4/26/16: At the start of the day they were still circulating hot brine and now getting return temperatures of 130 F. The IA was producing very little gas at this point suggesting that the hydrates may have been taken care of. During the night they had put more methanol down the IA as well. The amounts of methanol pumped were small but over the night they were able to get approximately 5 gallons down the IA. They continued circulating through the day, but during the night they became satisfied with the results they had seen from circulating the hot brine. At this point they pulled the 1" pipe and rigged down the annular preventer. They rigged up wireline and ran a cement bond log (CBL) log and a temperature log. Afterwards they pulled the bridge plug and attempted to circulate to the IA from the tubing. They were unsuccessful in their attempt to circulate. 4/27/16: The next step taken was to run another CBL log with 500 psi on the IA. Since their results from the logs the night before were under question, and before they were done with this log, the request for another CBL log with 1500 psi on the IA came from town. Town was unsure of what they were seeing in the upper portion of the well that was stopping them from circulating and believed that higher pressure on the IA would give better results. During this time I was told to arrange transportation back to Deadhorse due to other work that needed attention. I traveled back to Barrow in a Steiger tractor and stayed the night as there were no flights to Deadhorse that evening. 4/28/16: I flew back to Deadhorse via Ravn Aviation. Summary: With the failed placement of the initial abandonment cement plug, and the • obstruction in the Inner Annulus near surface (unknown but assumed to be hydrates by Solsten) — thus preventing circulation from the tubing into the IA— I traveled to location to witness operations that were intended to lead to placement and testing of a second abandonment plug. During my time at Iko Bay#1, all well activities were focused on clearing the tubing-casing annulus to enable circulation — no 2nd cement plug was ever pumped. With the short amount of time left before tundra travel is suspended, it is more than likely this operation will be halted and revisited next winter.

I. Supervisor FROM: Johnnie Hill SUBJECT: Cement Plug Petroleum Inspector IKO Bay #1 BLM PTD 100-136 %GAHMED SEP 2 6 2016 Sundry 316-122 4/20/2016: I arrived at Barrow and was met by a Marsh Creek employee and was driven out to site by a tucker. With me on the ride out was Joe McInnis a BLM contract company man. It took us 2hrs to get out to the camp and we met with Mike Grubb (Marsh Creek) on arrival. He explained where they were at in the cement job. He did say that they did tag cement at 915 ft in the tubing and did a pretest on it before we got out there — the pre-test failed. We then rode out to the well head and Marsh Creek proceeded to try bringing the tubing up to 1500psi for the pressure integrity test of the cement plug in the tubing. Pump was shut down after reaching 1500psi and pressure was monitored for 30 minutes. Pressure dropped at least 100psi after 30 minutes. I told Mr. Grubb that the test was zero-leakage criteria (no pressure loss). They attempted additional tests (pressured back up to 1500psi) as he thought there might be air in the tubing that needed to get out. So they would pressure up/monitor/bleed off, repeating to cycle for more than 1 hour with no change to the test performance. They tried the same with the annulus and had the same results as the tubing. Stopped well operations at 2200hrs and went back to camp. 4/21/2016: Morning safety meeting followed by a teleconference with town folks on next steps. I listened in on the conference call: Marsh Creek representatives Lucas Munisteri and Jesse Mohrbacher (Anchorage) and Rob Brumbaugh (BLM; Anchorage) were involved. Most of the day was spend by BLM and Marsh Creek updating the abandonment procedure. Final plan (coordinated with AOGCC engineering staff) was received from Marsh Creek and BLM around 1630hrs. Plan involved perforating below 900 feet and circulating the well (down tubing, up annulus) to make sure the well is dead before pumping second cement plug. 4/22/2016: Decision was made to run a cement bond log with positive pressure and at zero pressure before perforating to circulate the well. Pollard E-line ran the logs and sent to town for review — deemed inconclusive by reviewers. Decision was then made to run a temp log and then run another cement bond log at 500psi and at Opsi. Results were again sent to town for review and it was determined that they wanted to perf from 2016-0420_Abandon IkoBay-1_ih.docx Page 1 of 2 • • 912 to 914 ft. E-line was rigged down after perforating and they tried to circulate down the tubing and up the annulus without success. At this point they started looking for methanol to pump in the well thinking there were hydrates in the annulus blocking the circulation path. They obtained methanol from the Barrow gas plant. 4/23/2016: I rode back out on the tucker to Barrow to fly back to Deadhorse. Guy Cook will be traveling to Iko Bay #1 tomorrow to continue our witness of the P&A. 2016-0420_Abandon_IkoBay-1 jh.docx Page 2 of 2
