The pressures were confirmed to be TBG/IA/OA= SSV/2250/100. A MIT-T and CMIT-TxIA both passed to 2500 psi on August 22, 2015 confirming two competent barriers to formation. However, the well continues to show signs of inner annulus repressurization when shut in. The well has been reclassified as Under Evaluation for further diagnostics. Plan Forward: 1.

The passing tests confirm two competent barriers in the wellbore. The well is reclassified as Operable. • Well status is Operable • Annuli are fluid packed • A SSSV is not required Use caution while placing the well on production due to fluid packed annuli and the potential of annular fluid expansion.

Supervisor DATE: December 7, 2000 FROM: Jeff Jones, Petroleum Inspector SUBJECT: Safety Valve Tests Prudhoe Bay Unit BPX / F-Pad ThUrsday, December 7, 2000: I traveled to BPX's F-Pad in the Prudhoe Bay Field to witness Safety Valve System tests. Merv Liddelow, BPX representative in charge of testing, performed the tests in a safe and proficient manner. Of the 28 wells tested, 10 failures were witnessed. For the most part,, frozen contaminants (water) in the block valves upstream of the pilots and in the SSV hydraulic control lines caused the failures. On 12/8/00 Mr. Liddelow indicated to me that aii S¥S failures had been corrected and J ~. successfully re-tested. The 17.8% SVS failure rate requires a 90-day test cycle for this pad. The AOGCC test report is attached for reference. I conducted 28 well house inspections concurrent with the SVS tests. Due to recent high winds, several well houses were drifted with snow inside. In addition, SVS hydraulic fluid leaks were noted on wells F-12 and F-13A. Mr. Liddelow indicated that these items would be addressed. No other exceptions were noted. SUMMARY: I witnessed SVS tests and conducted well house inspections on BPX's F-Pad in the Prudhoe Bay Field. 17.8% failure rate = 90 day test cycle. 28 wells, 56 components tested. 10 failures. 17.8% failure rate. 28 well house inspections conddcted.

The leak was detected in the gas lift mandrel at Station #1 at 13,510 feet MDBKB. A patch was run in 7/92 to repair the leak. A leak detection log found that lift gas now leakS through the non-retrievable patch set across GLM #1. Attempting to remove the patch with coiled tubing is considered to have a high risk of failure. A rig work over (RWO) is proposed to replace the tubing and bring F-43 back into compliance.4' Please allow F-43 to continue to produce under variance until the RWO is completed.

Walker Date: Production Engineering Supv. Joe Hurliman t~it D~r ~[(~ Supervisor, Gra ity inage From: January 5, 1995 Subject= F'43 Tubincj Leak Repair There'is a tubing patch across GLM #1 to seal a hole caused in 7/92 when the S/O was pulled in two. It is now leaking causing multipoint gas lifting between Stations #1, 2, & 3. There is a 2-7/8" nipple insert in the tubing tail to provide a WL profile of smaller diameter than the patch ID for gas lift work. F-43 last tested (12/26/94) at 4900 GFR,-2300 NOR, 1300 GOR, and 54% WC with 3 MM gas lift. (1) Mill out and pull the Otis Merla tubing patch across GLM #1 from 13,480'- 13,501' ELMD. (2) Pull the 2-7/8" nipple insert in the 4-1/2" tubing tail at 13,625' MD to allow 3-3/8" perf guns. (3) RU WL and tag TD with a 3-3/8" DG and TEL. Note: once the Merla patch and the nipple insert are pulled, the minimum restriction is 3.725" at the XN nipple. Note: the last TD tag was 14,052' ELMD $/I (?/13/92). Obtain a variance due to the tubing GLM leak and test F-43 on an open 90 step choke. Add perforations as per separate program. After testing, if the GOR is unchanged, install a new gas lift mandrel patch over the leak in GLM #1, optimize gas lift, and retest. If possible, do not reinstall the tubing tail insert at this time so that future frac operations may be programmed. JH/MJC/mjc [1~ cc: F-43 Well File (w/a) FEB -7 ~995 0il & Gas Cons.

The Drilling fluid program will consist of an 8.5 - 9.5 ppg spud mud in the 17- 1/2" hole, a 9.0 - 9.7 ppg water base mud in the 12-1/4" hole and a 9.2 ppg water base mud in the 8-1/2" hole. Drill 17-1/2" hole to 1400'. Kick-off and directionally drill to 13-3/8" casing point at 2758'MD. Run and cement 13-3/8" L-80 Buttress casing to surface. Install blowout prevention equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer. Maximum possible bottomhole pressure is 4390 psi at 8800' TVDss based on original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVDss and an oil column to 8800' TVDss. A formation leak-off test will be performed 10' below the 13-3/8" shoe. Directionally drill 12-1/4" hole to the 9-5/8" casing point above the Sadlerochit Sandstone. Run 9-5/8" 47# L-80 NSCC casing to within 10' of 12-1/4" TD and cement with Class G cement around the 9-5/8" shoe. The annulus will be freeze protected by dry crude. Directionally drill 8-1/2" hole to TD. Run 7" liner from TD to 250' inside 9-5/8" casing shoe and cement using Class G cement. Clean out to 7" float equipment. Change over to NaCI completion fluid. Test casing and lap to 3000 psi. Run 9-5/8" production packer on tubing. Set packer 50' above top of liner. A subsurface safety valve with dual control lines will be placed 100' below base of permafrost. Install and test Xmas tree. Displace tubing to diesel. Set and test packer. The well will be perforated after the rig as been released. Fluids incidental to the drilling of a well will be pumped down the 9-5/8" x 13- 3/8" annulus of the well.
