An initial CBL was run then a remedial cement job was pumped and another CBL run. Its original perf strategy was conservative due to concerns about water from the fault crossed at 10,134' (60' of throw, ~0.3 bpm loses) and a fracture at 10,472' MD (no throw, no noticeable increase in loses). In 2017 a CT milling and mud acid job was performed on this well. Coil milled to 10960’ before running into weight transfer issues, SIT have been performed so the liner should still be clean down to at least 10960’. We have perfs deeper than 10960’ however if we are not able to drift past 10960’ we will forego shooting perfs below 10960’. Objective: Use coil to add new perforations. Slickline: Drift to deviation with 1.75” OD tool string noting tight spots and samples return in sample bailer. Sundry Procedure (Approval Required to Proceed): Note: The well will be killed and monitored before making up the initial perfs guns. This is generally done during the drift/logging run. This will provide guidance as to whether the well will be killed by bullheading or circulating bottoms up throughout the job. If pressure is seen immediately after perforating, it will either be killed by bullheading while POOH or circulating bottoms up through the same port that opened to shear the firing head. Coil Tubing: 1. MIRU Coiled Tubing Unit and spot ancillary equipment. * Add Perf W-18A PTD:213-081 2. Bullhead 126 bbls of 8.4 ppg 1% KCl or 8.5 ppg seawater down the tubing to the formation. (This step can be performed any time prior to open-hole deployment of the perf guns. Timing of the well kill is at the discretion of the WSS.) a. Wellbore volume = (8517’ X 0.0087bpf) +(2608’X0.0039) = 84 bbls 3. MU and RIH with logging tools and dummy gun drift BHA to resemble perf gun. Tag PBTD prior to logging OOH. Or tag restriction at 10,9060’ MD. a. Contingency: Motor and mill may be used to clean liner to desired perf depths. b. Contact OE Brian Glasheen to discuss contingency plan. 4. POOH and confirm good data. 5. Contact OE prior to perforating for final approval of tie-ins. 6. Freeze protect tubing as needed. 7. At surface, prepare for deployment of TCP guns. 8. Confirm well is dead. Bleed any pressure off to return tank. Kill well w/8.4 ppg 1% KCl or 8.5 ppg as needed. Maintain continuous hole fill taking returns to tank until lubricator connection is reestablished. 9. Pickup safety joint and TIW valve and space out before MU guns.Review well control steps with crew prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety joint and TIW valve have been spaced out, keep the safety joint/TIW valve readily accessible near the working platform for quick deployment if necessary. 10. Break lubricator connection at QTS and begin makeup of TCP (1.56" Millennium or equivalent) guns and blanks per schedule below.

Sent using BlackBerry From: Davies, Stephen F (DOA) [mailto:steve.davies(aalaska.gov] Sent: Thursday, June 06, 2013 04:00 PM To: Sperry, Nathan Subject: PBU W-18A Permit to Drill Appliction Nathan, I have a couple of questions about this application: The application says the surface location of the well is 791' FNL, but the W-18 well is located 731' FNL. I'm assuming that 731' FNL is correct, but could you please confirm this? Or was the location re-surveyed? Just curious, why don't the ground-level elevations on the application form and the proposed directional survey match (52.88'vs 47.83')? Which is correct? I've noticed that this is a common problem--it occurs in many permit application packages, but this 5' difference is significant.
