In 2014 there have been 3 attempts to set water shut off plugs. On April 7, 2014 an IBP set in-between perforations. Sometime between April and August the IBP dislodged and became lodged in the SSSV. On August 1-2, Slickline was able to recover the SSSV and the IBP from the well. All IBP elements are believed to be recovered and the well was drifted with a 3.625" cent and 3.5" DD bailer to 12,486' MD. On Oct 13, 2014 a HEX plug was attempted to be set but inadvertently set off depth and had to be fished from the well. All pieces of the HEX plug were recovered. A second attempt to set a HEX plug was conducted on Oct 29,2014 but the setting failed. On Nov 01, 2014 the SSSV was set without issue and the well returned to production. Current SSSV in well: 4-1/2" BBE w/3 sets of standard packing&secondary lockdown Objective: Set plug @ 12,454' &dump+/- 10' cement on top (isolation plug of the FII sands) ' Add perf 12,356'—12,380' and (add perfs into the lower FIII, which is already perforated) • Procedure: E-Line 1.

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/T34" (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.

The Kekiktuk reservoir is assumed to be normal pressured at with a .44 psi /ft gradient (8.5 ppg EMW). There is a some pressure uncertainty with respect to this well due to concerns about the accuracy of static pressure data in END4 -06A (3.5 ppg EMW). The high estimate (8.5 ppg EMW) is based on virgin reservoir pressure in the zones below 10,299' TVD assuming they are not in communication with other wells. II. Stuck Pipe A. Endicott has a history of stuck pipe events both while drilling and running casing. Follow good hole cleaning, and tripping practices, as described in the END4 -04A Well Procedure. B. Minimize the time the drill string and casing are stationary across permeable zones to avoid differential sticking. Control API and HTHP fluid loss as recommended in the mud program. The 10.5 ppg mud could be as much as 4.0 ppg over reservoir pressure (The 3.5 ppg EMW is believed to be anomalous, with 6 -7 ppg EMW more representative of what is expected). III. Lost Circulation /Breathing A. Lost circulation is not expected. However, the Kekiktuk will be drilled 3 -4 ppg overbalanced. B. Well bore breathing may be encountered after weighting up the mud to drill the HRZ. There may be no cement outside of the window, thus there could be hydraulic communication to shallow permeable sands. An 11.5 ppg EMW FIT at the window at 8,700' MD/6,861' TVD is equivalent to 13.2 ppg EMW at the 13 -3/8" casing shoe. Previous LOT /FIT data indicate that rock strength at casing shoe should support this. Follow good hole cleaning practices, minimize ECDs, and minimize surge pressures to mitigate the chance of breathing. IV.

PPPOT Tubing and Casing. (last done on 9/27/2008). 3. Function test casing and tubing LDS (last done on 9/27/2008). 4. Pull SSSV if installed, drift and tag fill and dummy off any live GLMs. 5. Perform injectivity test. Monitor and record IA and OA pressures during pumping operation. 6. Full -bore cement squeeze perforations with 15.8 ppg cement slurry. Final cement volume should be determined by injectivity test and PBTD. Minimum cement volume should be sufficient to cover perforations and bring cement to the tubing tail at 13,058' TMD - approximately 600 ft. above the uppermost perforation. Assuming a PBTD of 13999', this requires a minimum volume of 35 BBLS to fill the liner and tubing. Desired volume is 45 BBLS of cement slurry. (Squeeze 5 to 10 BBLS into perfs and leave excess cement in tubing). Cement calculations: a. With PBTD of 13,999' - Tubing tail at 13,058' : 35 bbls b. Barrels to squeeze behind pipe: 10.0 bbls Total cement volume : 45 bbls 7. Run wireline drift of tubing and tag TOC. CMIT tubing /IA. 8. Jet cut the tubing at -8,900' MD. 9. Circulate the tubing and IA to 9.1 ppg NaCI brine. Freeze protect tubing and IA to 200' with diesel. 10. Set BPV. 11. Remove gas lift and production flow lines, remove well house from END 4 -02, 4 -04, 4- 06 and 4 -08. Level the pad for Doyon 14. Drilling Riq: 1. MIRU Doyon 14. Circulate out diesel freeze protect through tubing cut. Install TWC. 2. ND Tree. NU and test BOPE. 3. Pull and LD 4'/2" tubing from pre -rig tubing cut. 4. w /Slickline, run GR/Junk Basket to +/- 8800' MD. 5. RU Eline. Run USIT log in corrosion mode to evaluate the condition of the 9 5/8" casing from -8,800' to surface. 6. RIH and set CIBP at ±8,750' (based on corrosion log and lithology). End of Sundry Notice Drilling Permit: 7. MU whipstock. RIH (on 4" drill pipe) and set whipstock, mill window (8,700'), and drill 20' of new formation. Perform FIT test. 8.
