There was 7 feet of void in the IA (4 1/2" x 9 5/8" casing annulus) and 25 feet of void in the OA (9 5/8" x 13 3/8"). 1 instructed Jon to fill them up with cement and call when they had good hard cement to surface 6/7/2020: 1 returned to the well and again met with Mr. Arend. I inspected the cut off and found all string full of good hard cement. The marker plate has all the correct markings except the PTD was missing the 0 at the end. I ask them to put it on when welding the plate on.

The inner and outer annuli had been cemented to surface with the proposed top in the tubing at 1,800 ft MD. BP's schematic shows the bottom of the plug in the tubing to be at 8,400 ft MD, but with the plugged x -nipple at 8,531 ft MD I called the bottom depth just that (referred to as bottom in plugging data). We found the top of the cement plug at 1,529 ft MD (4 barrels high) with the 200 pound, 2-1/2" sample bailer slickline string. Minimal inclination at that depth. We then completed a passing pressure test to a target of 2500 psi. With no variables, the first 15 -minute interval seemed like a higher than expected pressure loss, but proved out on the next 15 -minute check. I credited the fairly large drop to the pump truck operator getting to pressure too quickly. The bailer was then broke down with a good cement sample observed.

The outer casing string is set @ 2004' MD which is very near the permafrost. GWO has determined that these wells are at risk for sudden S— wellhead movement, as demonstrated by 02-03A and 02-02A. As such BP has decided the well will be plugged and abandoned to mitigate HSSE consequence associated with this potential risk. The well is secured with a Tubing Tail Plug with a passing CMIT TxIA to 2500 psi on 5/26/2019, a passing MITT to 2882 psi on 12/30/2018, and a passing CMIT OAxOOA to 600 psi on 2/24/2010. Objective Place abandonment cement plugs in the wellbore, excavate and cut and cap the well 3' below ' original tundra and backfill. Procedural steps E-line/Fullbore 1. Perforate at 8400' MD through the 4-1/2" tubing and 7" casing. 2. Circulate down tubing and up OA with surfactant wash followed by 9.8 ppg brine. Maximum tubing pressure 2500 psi. Note that the IA has already been circulated to 9.8 ppg brine. ➢ 5 bbls MEOH ➢ 50 bbls hot (160 deg) freshwater+ surfactant; 2 gal/mgal F103 and 2 gal/mgal UO67 412 bbls 9.8 ppg brine 3. RU Cementers. Circulate down tubing and up OA with cement then swap to taking returns from IA with cement. This step will cement the OA and IA to surface. Maximum tubing pressure 2500 psi. ➢ 5 bbls MEOH ➢ 655 bbls cement per design (-40 bbls excess); Take returns from OA until good cement returns are seen then swap to taking returns from IA until out of cement. ➢ 2 bbls FW ➢ Drop foam wiper ball ➢ Chase ball with 25 bbls 9.8 ppg brine to displace TOC to MD. Fullbore 1. AOGCC Witnessed MITT to 2500 psi target pressure. Max pressure 2750 psi. Slickline 1. AOGCC Witnessed Tag TOC. Eline/Slickline 1. Perforate from 1290'— 1300' MD through the 4-1/2" tubing, 9-5/8" casing, and 13-3/8" casing. Fullbore 1. Pump down tubing taking returns from the OOA the following (note that he 13-3/8" x 18-5/8" annulus has been displaced to dry crude during a RWO in 1987).

After start-up, the wells will then be reclassified as Under Evaluation with POP parameters to prevent any over-pressure incidents. Please call with any questions or concerns.

The original 1971 vintage F-04 reached GOR in 2001. The 2003 CTD Sidetrack F-04A was shut in for integrity in 2006. In 2008 a RWO was performed to cut and pull the production liner and change out the tubing. The proposed plan for F-04B is to sidetrack out of the F-04 7" liner with the Nordic 1 Coiled Tubing Drilling rig on or around Sept. 01, 2010. The existing perforations will be isolated by the pre-rig cement squeeze past the whipstock. The sidetrack, F-04B, will exit the 7" liner drill a 4.25" hole through the Kingak, run a 3-3/16" liner across Kingak and drill a 3" hole to the target in the Ivishak Zone 1A/1B.

DIRECTIONAL Other Services Line 1 Remarks (1) All depths are Measured Depths (MD) unless otherwise noted. (2) All depths are Bit Depths unless otherwise noted. (3) All True vertical Depths (TVDSS) are Subsea corrected. (4) All Formation Evaluation data is realtime data. (5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to log this well . (6) Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance Sub (Inner and Outer Downhole Pressure, Vibration and Downhole weight on Bit) , a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor. (7) Data presented here is final and has been depth shifted to a Primary Depth Control (PDC) log provided by Schlumberger GR CNL dated 20 Aug 2010 per Jennifer Flight with BP Exploration (Alaska) , Inc. (8) The sidetrack was drilled from F-04 through a milled window in a 4 1/2 inch liner. Top of window 9649 ft.MD (8293.4 ft.TVDSS) Bottom of window 9656 ft.MD (8299.8 ft.TVDSS) (9) Tied to F-04 at 9600 feet MD (8253.3 feet TVDSS) . (10) The interval from 11658 ft to 11681 ft MD (8988.2 ft. to 8987.9 ft. TVDSS) was not logged due to sensor to bit offset at well TD.
