Proposed plan for 06-16B Producer: Prior to drilling activities, screening will be conducted to drift for whipstock and MIT. The 3-1/2" liner top packer will be pulled. E-line will set a 3-1/4" packer whipstock. See 06-16B PTD request for complete drilling details - A coil tubing drilling sidetrack will be drilled with the Nabors CDR2 rig. The rig will move in, test BOPE and kill the well. A single string 2.74" dual string window (3- 1/4"x9-5/8") + 10' of formation will be milled. The well will kick off drilling in the Ivishak Zone 4 and lands in Zone 2. The lateral will continue in Zone 4, 3 and 2 to TD. The proposed sidetrack will be completed with a 2-3/8” 13Cr solid liner, cemented in place and selectively perforated post rig (will be perferated with rig if unable to post rig). This completion will completely isolate and abandon the parent Ivishak perfs. This Sundry covers plugging the existing perforations via the packer whipstock and liner cement job or liner top packer, if the liner lap pressure test fails (alternate plug placement per 20 AAC 25.112(i)).

Cumulative production for the lateral reached 1.29 MM BOE before becoming HGOR in May ‘22. There are no known integrity issues. The 06-16B CTD ST is planned for Q4 of this year, but a stuck LTP must be fished beforehand. Several attempts to fish the LTP were unsuccessful with: slickline, braided line, e-line 100k stroker, and 1.75” CT. Caliper data shows the LTP is severely flowcut. The LTP was left unbaited after pulling out the spear on the last CT fishing attempt. Objective: Fish stuck 45 KB LTP with Thunderbird #1 LTP Fishing History: x Slickline attempted to fish the 45 KB LTP with GS, Pulled out of FN after 5 min of jarring. x Slickline baited with spear / 2.81” Grapple, pulled out with 100# overpull x Slickline ran caliper indicating a severely flowcut FN. Replanted spear. x Slickline Jarred for 5 days on spear, released spear x Slickline Planted Old Style Weatherford releasable spear x Slickline and Braided line jarred for multiple days, slickline released spear x Slickline Planted Old Style Weatherford releasable spear (OD = 3.65", grapple OD = 2.81", OAL =29") x Eline latched into baited LTP with welltech 100k stroker. Unable to retrieve LTP with max pull 100k. x 1.75” Service CT latched into baited LTP, Spear pulled out of LTP after 5 jar licks. x LTP is currently unbaited.
