The first leg (11-22A)was completed in August, 1995 and the second leg (11-22AL1)was completed in May, 1996 with CTD. Both were completed with slotted liner. A RST Log in 1999 estimated the GOC at 10300'. In 2001, the well was perforated from 10662' to 10700'. In May 2002, an addperf was completed from 10321' to 10308' and finally in September 2002, another addperf was completed from 10303' to 10308'. Average well test results in 2004 shows 28360 scf/stbo GOR. From January until July, the well had an average of 32440 scf/stbo GOR and increasing to 49420 scf/stbo in August and September 2005. IA and OA started tracking in 2007. A LDL was run in 2013 showing leaks at 65' and 7991'. A CMIT-IA x OA passed to 1200 psi. Two sealtite jobs were performed in 2013 and a combo IAxOA passed to 2500 psi in 2014. The IA and OA were still tacking when it was brought back on line and it was not manageable with bleeds. Scope of Work: The primary objective of the RWO is to fix the IAxOA communication and run a deep scab to cover existing perfs Pre Rig Prep Work: W 1 PPPOT-IC to 3500 psi, PPPOT-T to 5000 psi, Check all LDS for movement. F 2 MIT-T to 3500 psi, MIT-IA to 3500 psi to establish a leak rate. MIT-OA to 1200 psi E 3 Perform a power jet cut at 9885' MD. This depth corresponds to 2' above the lower collar of the pup joint directly above the packer. According to the tubing tally the top of the pup joint is at 9878' MD and the top of the packer is located at 9887'. See attached tally from July 12th, 1995 F 4 Circulate the wellbore at a max rate with 9.8 ppg brine (total volume of brine should be -915 bbls which is 1.5 of wellbore volume). FP well with diesel to 500'. Perform a post cut CMIT-TxIA to 1000 psi. ✓ 5 Set a TWC, ND the tree, NU the dry hole tree, PB IA and upper OA Valves 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-h/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-9885' MD • RIH with drillpipe and a set of seals, test down the DP against the plug to 3500 psi • RU Eline and run USIT. Set RBP and cut casing. Pull and LD old 9-5/8" casing. • Change out upper rams to 7" fixed • Run 7" tieback from 7959' to surface. Cement tieback to surface with -545 bbls of 15.8 ppg Gasblock Cement. Land casing in existing wellhead. Install packoff and test • Perform drill out. PT casing to 3500 psi. Pull RBP • Mill and recover old packer at 9888' • Run 4-1/2" scab liner with TOL -9800' MD. Cement with -20 bbls of 15.8 Class G cement • Perform drill out run and clean up shoe track • Run new 4.5"tubing 13Cr with 7" x 4-1/2" gas lift completion. • Set packer and MIT-T& MIT-IA to 3500 psi • Set a TWC and RDMO.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. The permit is for a new segment from existing well DS 11-22A, Permit No. 95-87, API No. 029-22035-01. Production should continue to be reported as a function of the original well identifier API 029-22035-01. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. David W.
