PTD 199-061; Sundry 320-092 01/24/2021: I met with Matt Linder (Hilcorp Well Site Lead) at PBU E -28A and looked at the information on the marker plate. I asked the welder to add "PBU" to the well name, a "0" at the end of the PTD, and "-00" at the end of the API number. The cut off is over 4 feet below tundra and the cement was to the top of the casing strings and hard.

Mark Spiller was the BPXA rep on sight for the plut verifications. Wireline had a 3501b tool string rigged up that consisted of weight bar, spangs, and a 3-1/2" sample bailer. The tag showed TOC to be @ 8784 ft MD, and the tool string was pulled out of the hole. MIT testing was performed amd both MITs passed without any issues. After all testing was completed the sample bailer was removed and brought into the ops cab for inspection. The sample consisted of clean-up slurry and the wiper ball so I had them run back down and try again. The new tag depth was only 1 foot lower @ 8785 ft MD and the bailer returned to surface with a good cement sample.

The well was sidetracked with coiled tubing drilling in October 1999, but in recent years has spent significant time shut-in due to gas handling constraints. The surface casing is set in the permafrost (1793' TVD) and thus identified as a potential for subsidence issues in the follow-up of 02-03 and 02-03. The following proposed work would fully P&A the well. Objective Place cement plugs in the wellbore. Excavate and cut casings 3' below original tundra level and install marker cap. Procedural steps DHD 1. Fill the SSSV control line with one control line volume of cement for isolation. Slickline 1. Pull the tubing plug at 9026' MD. Fullbore 1. Perform injectivity tests in preparation for cement. For the first test, pump down the tubing to formation, inject at several pump rates. Record injection pressure at each rate. For the second test, rig up to pump down the OA through the open shoe. Attempt to establish injectivity out of the shoe by slowly increasing pressure to a maximum of 1200 psi. If injection is established, record pressures at several increasing pump rates. ➢ Note: The work proposed in the rest of this procedure assumes that injectivity is not established down the OA. If this step successfully establishes injectivity, a revision will be submitted to cement the OA from surface, and eliminating the tubing punch at 1400' MD. 2. Rig up to pump down the tubing to the perforations. Pump the following schedule to abandon the perforations, leaving cement in the tubing with a designed TOC at approximately 9,000' MD. ➢ 10 bbls McOH ➢ 10 bbls freshwater spacer ➢ 21 bbls Class G cement per the design below ➢ 5 bbls freshwater spacer ➢ Foam spacer ball ➢ 205 bbls of diesel for displacement Cement Type/weight: Class G 15.8 ppg mixed per WSL.

When BP is finished with the reviews of the wells, please arrange for a meeting to present your findings to the AOGCC. That can be coordinated with Victoria.

I'm investigating the details now, but I do not believe these wells present a risk.The 13-3/8" is a second conductor, and not coupled to the inner casing strings at the wellhead. In the event the 13- 3/8"were to subside, it would not impart a load to the inner casing strings via the wellhead. I will follow up onll these wells as soon as possible.

While the cement squeeze appeared to have gone well, a subsequent pressure test failed. Apparently there was contamination to the cement and the packer continued to leak. The problem was resolved by eMtending the 2 7/8" sidetrack liner upward to a point above the production packer. This installation was successfully pressure tested from above and below. Perforating for production is now in progress. The AOGCC inspector on the slope was kept informed of progress. The inspector was unavailable for the final pressure testing but a copy of the test chart was faMed to him. This information will be incuded in the completion report along with a well schematic showing the addition of the liner extension. Please contact me if further information is needed prior to the normal completion report.

We will consider this as part of the completion plan. As such, it can be reported on the 10-407. Thanks, Blair Wondzell "Stagg, Ted 0 (ORBIS)" wrote: Please refer to an E-28a well schematic that was faxed to you 30 minutes ago. A coil tubing sidetrack of E-28a was nearing completion yesterday when the 5 1/2" x 9 5/8" production packer failed during a pressure test of the 2 7/8" sidetrack liner. The pressure test was performed from surface with 8.5 ppg KCl in the hole. The tubing and 2 7/8" liner held 2000 psi surface pressure but communication to the inner annulus was established at a surface pressure of 2100 psi. A failure of the production packer was suspected and later confirmed a Spinner log run on e-line. The communication path is via the "PBR" located on top of the original 5 1/2" liner. As is common practice, no seals are used in this PBR to avoid trapping pressure between the production packer and the packer on top of the 5 1/2" liner. Pressure applied to the tubing is therefore transmitted through the PBR to act on both the bottom of the production packer and the top of the liner top packer. In the process of pressure testing the 2 7/8" liner the differential pressure across the production reached the point of failure. The differential at which the production packer failed was approximately 2900 psi. Since the density of some of the fluid in the inner annulus is unknown there is some uncertainty as to the exact differential pressure across the production packer at the time of failure. Cement was used to repair the failed production packer. Twenty (20) bbls of 15.8 ppg cement was pumped, as a balanced plug, to place cement through the PBR to a height of approximately 200 feet above the production packer. The equavilent height of cement was left inside the tubing to form a balanced plug. The cement inside the tubing has now been drilled out and pressure testing with AOGCC witness will take place today. The plan is to test the tubing, and the unperforated 2 7/8" liner to 2500 psi. This will test the cement plug used to repair the failed production packer. The inner annulus will also be tested to 2000 psi surface pressure. Following a successful pressure test the 2 7/8" liner will be perforated for production. Please advise if further information is needed prior to the normal completion report on this sidetrack.

We are now planning to resume drilling operations on Sept. 20, 1999. The well target is unchanged from the one permitted under Permit Number 99-61. The directional path to be followed in drilling to this target has been changed slightly to increase hole inclination through a troublesome conglomerate interval. A copy of the new directional plan is attached. The existing window will be utilized. Kick off cement will be layed above the fish and a sidetrack around the fish will be initiated just below the window. Please contact me at 564-4694 if further information is needed.

The sidetrack, E-28a, will target Zone 1, 13P sands just above the heavy oil tar. This sidetrack will be conducted in two phases. Phase 1: Set CIBP and Whipstock Anchor: Planned for July 24, 1999. · A Tubing Integrity Test will be performed. · Service coil will be used to set a CIBP followed by a whipstock anchor. Anchor orientation will be confirmed by running a memory inclinometer on service coil. Phase 2: Install Whipstock, Mill Window and Drill Directional Hole: Planned for August 1, 1999. Directional drilling coiled tubing equipment will be rigged up and utilized to install the whipstock tray, mill the window and drill the directional hole as per attached plan to planned TD of 12,370' MD (8,970' TVDss). Mud Program: - Phase 1: Seawater · Phase 2: Seawater and FIo-Pro (8.7 - 8.8 ppg) Disposal: - No annular injection on this well. - All drilling and completion fluids and all other Class II wastes will go to CC-2a for injection. - All Class I wastes will go to Pad 3 for disposal. Casing Program: - 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 9,740' MD and cemented with approx. 21 bbls. cement to bring cement 200 ft above the window. The well will then be perforated with coiled tubing conveyed guns. Well Control: - BOP diagram is attached. - Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 4000 psi. - The annular preventer will be tested to 400 psi and 2000 psi. Directional - See attachments. - Kick Off: 10,155' MD (8,763' TVD ss) - TD: 12,370' MD (8,970' TVD ss) - Magnetic and inclination surveys will be taken every 30 ft.
