The well has been SI since September 2012 due to TxIA and has had IAxOA issues since 1994. The well has a history of leaks at gas lift mandrels and has been fixed with extended packing gas lift valves and patches. The tubing currently has 5 known leaks found from a LDL from November 2012. Four of the leaks are GLMs and the last is from the patch set in 1997. There is also a small leak near the production packer. The caliper shows the tubing is in fairly good condition, but 5 of the 12 GLMS are compromised. 14-26 needs a RWO to replace the tubing and fix the IAxOA communication. ✓ / Scope of Work: The primary objective of the RWO is to restore integrity production casing and the tubing Pre Rig Prep Work: W 1 PPPOT-IC to 3500 psi, PPPOT-T to 5000 psi, Check all LDS for movement. F 2 CMIT-TxIA to 3500 psi. MIT-OA to 1200 psi. E 3 Dump bail 10' of cement on top of the IBP at 10,468' MD. Perform a power jet cut 3'-5' down in the first full joint above the upper patch. F 4 Circulate the wellbore at a max rate with seawater (total volume of seawater should be -1025 bbls which is 1.5 of wellbore volume). FP well with diesel to 2500'. Perform a post cut CMIT-TxIA to 3500 psi. ✓ 5 Prep annular valves, Set a type a TWC. O 6 Remove the well house&flow line. Level the pad as needed for the rig. Proposed RWO Procedure: • MIRU Doyon 14. • ND tree. NU and test BOPE with four preventers configured top down (annular, 9-5/8" fixed rams, blind shears, mud cross and 3-1/2" x 6"VBR's). Test the blind and VBR's to 3,500 psi and the annular to 3,500-psi. Pull TWC. • Pull the 4-1/2"tubing from the cut at-10207' MD • RU Eline and run USIT. Set RBP and cut casing. Pull and LD old 9-5/8" casing. • Cut off old Vetco gray wellhead. Run new 9-5/8" casing and cement to surface. - • Install new sliplock wellhead on landing ring. • PT casing to 3500 psi. • RIH with fishing BHA and recover remainder of tubing (with two patches), seals and PBR from old packer. • MIII and recover packer • Scrape casing and 7" liner top packer to ensure that completion can be stung in. • Run new 4.5" tubing 13Cr with 9-5/8" x 4-1/2" packer configuration • Set a TWC and RDMO.

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. If you require any additional information, please contact me or my alternate, Anna Dube, at 659-5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator • BP Exploration (Alaska) Inc.

( SUMMARY OF WELL OPERATIONS ARCO Alaska, Inc. perforated DS 14-26 at selected intervals in the Sag River Sand of the Prudhoe Bay Unit on 10/24/91 (10850-10852'MD, Ref Log: BHCS 12/30/81). Produced fluids were in the wellbore during perforating operations. All wireline work was done through a 5000 psi WP BOP/Lubricator tested to 1.2 times the maximum expected surface pressure. The SSSV was installed at the conclusion of the perforating and clean-up operation. A short summary of the work is given below. - Began perforating operation on 10/24/91. - RU perforating unit and pressure tested equipment to 3000 psi. - RIH w/gun # 1, tied-in, and shot # 1: 10850-10852'MD @ 4 spf. - POOH. All shots fired. - Secured well. RD. RECEI¥ D DEC 1 2 1991 Alaska Oil & Gas Cons. Comm~ss'to~ Anchorage 5 4 3 2 COtL£D 1UBI~ UH]T BOP E OU ! PP.E,t 1. 504)0 PSi ?"

Upon arrival Parker was still nippling up the BOPE equipment. The test commenced at 10,45 p.m. and was concluded at 2:05 a.m. There was a Ross Hill representative to check the BOPE accumulator closing equipment. We opened and clos.~ the accumulator system twice to assure the full charge of 3100 psig would be reached and remain at a constant pressure of 3100 psig. After closing the H.C.R. valve, upper and lower pipe rams, and annular preventer. A constant minimum pressure of 1300 psig was reached during each test. I filled out the A.O.G.C.C. BOPE test report which is attached. In summary, I witnessed the BOPE test on ARCO's DS 14-26. There were no failures.

Logs will be run across selected intervals. A 13-5/8" 5000 psi RSRRA BOP stack will be used. The BOP equipment will be pressure tested each week and oper ationally tested each trip. A string of 5½" 17# L-80 tubing, packer and necessary provisio for subsurface safety equipment will be run. A non-freezing fluid will be left in all un- cemented annuli within the permafrost interval. Selected intervals within the Sadlerochit to be perforated and reported on a subsequent report. A 5000 psi NP wireline lubricator, tested to working pressure, will be used on all wireline work. The packer will be set ahoy the Sadlerochit. The downhole safety valve will be tested and installed upon conclusion of job. The 13-5/8" 5000 psi RSRRA BOP stack will be tested to 5000 psi. A surface dlverter s~vstem will be installed and operationally tested prior to spud at least daily thereafter. 23 I hereby certify that the foregomg ~s true and correct to the best of my knowledge SIGNED~, ~~ TITLE Dist.
