On arrival to location I met with Hilcorp representative Rob Bryan and he told me that this one of the wells that BPXA had cemented off but not cut deep enough. Rob also told me that they had just gotten it cut off 3 feet below tundra level. I inspected the TOC and all casing string were full of good hard cement from when BPXA had topped it off. I then inspected the 20" x 3/8" marker plate. It is the proper size with all the proper markings on it. I told Rob OK to weld it on and cover it up.

In 1995 the well was discovered to have a production casing leak and collapsed tubing. In 2014 and 2015 15-24 was suspended with cement to surface in all strings under sundry #314-532/ #315-489 and the wellhead was cut and temporarily capped with a marker plate approximately 1 foot below pad grade. Objective Excavate and cut off all casings 3’ below original tundra, permanently install well name cap, and backfill excavation. Procedure 1. Excavate and Cut off all casings 3’ below original tundra level. 2. AOGCC witness of cut-off casings before any top job commences. 3. AOGCC witness cement tops in all annuli. Top off with cement as needed. 4. Bead weld marker cap on outermost casing string. Photodocument all steps and AOGCC witness of installed cap.

Attempt unsuccessfully to pull tubing from pre-rig cut. R/U Slickline. Lock open SSSV. Memory log & gauge ring run, Slickline parted at rope socket due to SSSV problems. R/U to fish Slickline, SSSV still causing problems. Cut tubing below SSSV via Slickline (-2230'). RD Slickline. Leave Slickline fish in tubing. Pull & lay down tubing to 2230'. RIH w/fishing assembly and overshot tubing. Tubing parted -5780' (near pre-rig tubing leak, above collapse). Lay down tubing. RIH w/burn shoe to wash over collapsed tubing. Encounter obstruction, POOH. Burn shoe had missing quarter & was also bent. RIH w/string mill BHA. Clean two tight spots, hard tag w/bullnose @5722'. POOH. RIH w/smaller bullnose, string & watermelon mills. Clean tight spots, tag stub @5780'. POOH. RIH w/outside cutter cut & pull collapsed tubing down to 5941'. RIH w/overshot, attempt to fish remaining tubing. Tubing stuck IVO GLM #3. Attempt to establish injectivity down tubing. Failed. Charted pressures on injectivity test for 30 minutes. Performed blind backoff& POOH. One joint removed. Set 7" cement retainer @5800' (above cretaceous leak in 7" casing). PT above (good test). Sting into retainer. Squeeze 72 bbls below retainer & lay in 56 bbls above retainer. Cut & pull 7" casing @3370'. Mill off 10' of cement in 7" casing & hard tag 15k down w/AOGCC witness. Set 9-5/8" cement retainer @3300'. PT above retainer (failed). Sting into retainer and attempt to establish injectivity (failed, charted). POOH. RIH w/3-1/2" fox kill string. Land string @3250'. Set & test TWC from below. ND BOPE, NU tree. Pressure test tree. Pull TWC. Cement through tree down kill string and back to surface via IA/OA valves. Shut-in well fully cemented (including tree). RDMO. The wellhead is currently in the process of being removed. Once removed, the blue goo in the conductor will be removed and replaced with cement. The plan for this well is for the status to remain suspended with the wellhead removed about one foot below tundra, with a mechanically fastened marker plate a top the tubing/casing/cement.

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.

The rig and sUrrounding area were clean and orderly. I found no noncompliances on my visual inspection. The BOP test went well with all equipment functioning and holding the pressure test. The only failure was a gas detector module in the pits that showed need for calibration. In summary, the BOP test on Doyon Rig #9 went well. One noncompliance was found, the gas detector in the pits, which will be fixed when their electrician arrives on the 1st of November.

Excess non-hazardous fluids developed from well operations and as necessary to control fluid level in reserve pit will be pumped down the 9 5/8 X 7" annulus. The annulus will be left with a non- freezing fluid during any extended period. The annulus will be sealed with 300 sxs of cement followed by Arctic Pack. b. Wells within 200' of the proposed well are: DS15-1: 23' at 3150'md DS15-2: 146' at 3400'md c. The drilling fluid program and fluid surface system will conform to the regulations set forth in 20AAC25.033. d. The maximum surface pressure is based upon the BHP and a full column of gas to TD (0.10 psi/ft). e. Based upon previous logs obtained from DS15 wells, no productive zones are anticipated above 4000'tvd. f. No hazardous levels of H2S are anticipated in this well. Alaska Oil & Gas Cons.
