Commissioner Cathy FoersterN,�® GpNQ Alaska Oil & Gas Conservation Commission g_ O 333 West 7th Avenue, Suite 100 / I Anchorage, AK 99501 4._ 1-14 Re: Duck Island Unit Well Renaming Request Dear Commissioner Foerster, Hilcorp Alaska, LLC (HAK) requests a change to the naming convention of Duck Island Unit wells to remove the unused suffixes at the end of each well name. Well names currently include a forward slash "I" followed by an obsolete bottom hole location designator. HAK would like to retain the well number as well as the "A, B, C...." sidetrack designations but remove the "/suffix". For example, "DUCK IS UNIT SDI 1-09A/L21" would become "DUCK IS UNIT SDI 1-09A". The attached spreadsheet includes original and new names for all Duck Island wells. While performing the review of Duck Island well names, HAK found a single well, "DUCK IS UNIT SDI 4-20/M35" (PTD# 1861730), that should also be modified to include an "A" label to reflect the fact that the well is a sidetrack from the original "DUCK IS UNIT SDI 4-20/134" (PTD # 1861500). The original wellbore, abandoned 10/13/1986, was sidetracked to a new bottom hole location completed on 9/9/1987. This well appears to be one of the first sidetracks performed at Endicott. While the bottom hole code was changed, no letter was added to reflect the sidetrack. "DUCK IS UNIT SDI 4-20A" is also included on the attached spreadsheet.

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 altemate, Gerald Murphy, at 659 -5102.

Target injection rates would be in the 3 to 5 bpm range. Benefits associated to the project, including the booster pump, varies according to the gas injection and 3C2/1 offtake scenario, but can be characterized by a range of 500 to 1000 MBO of reserves protection.

The objective is to clean the recent perforations of debris and dissolve probable mud damage induced during drilling in sequence 3C1. Since the sequence was perforated (6/22/92) the sandstone has not produced to any significant degree (P.I. <0.1). Mud invasion damage is suspected since an overbalanced (1000 psi) mud system was necessary during drilling to control the higher pressured 3A interval from flowing.

Test for emulsion/sludging tendencies using APl RP 42 testing procedures (add 5000 ppm ferric ions to acid systems). Tests should be carried out using spent and unspent 6% HCI (w/ additives) and 6%HCl / 1.5%HF (w/ additives) at 200 deg. F. Adjust additives as required by test results.

As the attached AOGCC BOPE test report indicates there were two failures, the choke manifold valve failure was repaired and retested this date. Parts were ordered for the annular master accumulator control valve and I was contacted by Doyen rep. Mike Droody an 4/25/92 and informed that the valve had been repaired and retested. In summary, I witnessed the BOPE test at BPX DIU SDI 4- 44/M-44 well on Doyen Rig No. 15. The two non compliance items uncovered during this test were repaired and retested by 4/25/92.

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 blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035 and the mechanical integrity of the injection wells must be demonstrated under 20 AAC 25.412 and 20 25.030(g)(3). Sufficient notice (approximately 24 hours) of the MIT before operation and 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.

Rule 4c specifies that surface casing be set no deeper than 2700' TVD. Prudhoe Bay Drilling proposes to set 13-3/8" surface casing at 3464' TVDss / 3865' MD in order to 1 ) case off the build section and 2) attempt to minimize torque while drilling the 12-1/4" hole section.

E till 800' MD. At 800' MD the build rate is reduced l.~ 0,88°/100 and a left turn is started to align the well bore with the target, At 1500' MD the turn is st~pr.)ed and the direction held at S 82.75 E, wt~ile increasing the build rate to 1.5°/100. At 2500' MD the. bu'ld rat(: again increased to 2.0~/100 tilt 3765' MD and an angle of 49.470 is held to the target at 13961' MD and finally to the TD of 14615' MD, For the close approach analysis, all other wells were computed from gyro data provided by PBD. /,s above, well 4-44/M-44 ho~ four crossings with existing wells, and 6 closo approaches within 100 ft. Five the close approaching wells exist from the surface to the KOP of §00' TVD, The remaining close apt;roach with 4-46/N-39 exists from 500' TVD to 700' TVD, after which 4-44/M-44 moves away southward.
