In 2021, all existing perfs were shut off with a CIBP due to HGOR, then 450’ of Z1A perfs were added up hole. In 2022, all existing perfs were shut off with another CIBP due to HGOR, then 186’ of Z1A perfs were added up hole – These perfs have since become HGOR. We evaluated the LNR TOC previously estimated at 11,250 and revised the TOC to 10,925’ based off the June 2022 CBL. Objective: CT to set CIBP to isolate all existing perfs, then add 256’ of Z1A perforations using the open hole deployment system. Procedure: Coiled Tubing Notes: x Remote gas monitoring for H2S and LELs are required for Open Hole Deployment Operations x Due to the necessary open hole deployment of Extended Perforating jobs, 24-hour crew and WSS coverage is required. x 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. 1. After MU MHA and pull testing the CTC, tag-up on the CT stripper to ensure BHA cannot pull through the brass upon POOH with guns. 2. Load well with 1% KCL/SW down TBG. Max tubing pressure 2500 psi. 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 to top perf = 91 bbls i. 3-1/2” Tubing – 9700’ X 0.0087 bpf = 84 bbls 214-135 SFD CT Plug & Extended Adperfs 15-28B PTD:214-350 API: 50029222470200 ii. 2-3/8” Liner – 1665’ X 0.0039 = 7 bbls b. L-80 Tubulars 3. MU and RIH with logging tools and drift BHA: 1.56” dmy gun & nozzle. 4. Flag pipe as appropriate per WSS for adperf/CIBP runs. 5. POOH and freeze protect tubing as needed. 6. Confirm good log data. 7. RIH w/ 2-3/8” CIBP, set @ 11,295’ and PT to 1000 psi to confirm plug and LTP are holding. 8. At surface, prepare for deployment of TCP guns. 9. Confirm well is dead. Bleed any pressure off to return tank. Kill well w/KWF, 8.4 ppg 1% KCl or 8.5 ppg as needed. Maintain hole fill taking returns to tank until lubricator connection is re-established. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow. 10.*Perform drill by picking up safety joint with 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. a.At the beginning of each job, the crossover/safety joint must be physically MU to the perf guns one time to confirm the threads are compatible. 11.Break lubricator connection at QTS and begin makeup of TCP guns per schedule below. Constantly monitor fluid rates pumped in and fluid returns out of the well. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow. Perf Schedule *HES 1.56" Millenium guns were used to estimate for this job and calculate gun weights. Perf Interval (RUN 1) Perf Length Gun Length Weight of Gun (lbs) 3.62 lbs/ft 11006 - 11262 256’256’927 12. RIH with perf gun and tie-in to coil flag correlation. Pickup and perforate interval per Perf Schedule above. a. Note any tubing pressure change in WSR. 13. After perforating, PUH to top of liner or into tubing tail to ensure debris doesn’t fall in on the guns and stick the BHA. Confirm well is dead and re-kill if necessary before pulling to surface. 14. Pump pipe displacement while POOH. Stop at surface to reconfirm well is dead. Kill well if necessary. 15. Review well control steps and Standing Orders with crew prior to breaking lubricator connection and commencing breakdown of TCP gun string. 16. Ensure safety joint and TIW valve assembly are on-hand before breaking off lubricator to LD gun BHA. 17. FP well. 18.

The well is now a cycle well and the intent is to plug the existing perfs and add ~450’ of new perforations. Objective: The objective of this program is to plug off the existing perforations and add additional perforations to bring in more rate. Cerberus Modelling suggests making it past 13,000’ with ~230’ of 1.56”” guns w/ 1.50” coil tubing. Extended Add Perf 15-28B PTD:214-135 SL – Pull 2 trip 35 KB LTP from 9690’ prior to coil adperf job. Sundry Procedure (Approval Required to Proceed): Note: The well will be killed and monitored before making up the initial perf 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. 2. MU and RIH with GR/CCL logging tools and ~1.75” nozzle. Pull jewelry log for tie in. 3. POOH and confirm good data. 4. Bullhead kill the well w/ ~240 bbls of 8.4 ppg 1% KCl or 8.5 ppg seawater. (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 to top perfs = ~160 bbls 5. RIH w/ 2 3/8” CIBP, set @ 13,005’. 6. Contact OE prior to perforating for final approval of tie-ins. 7. Freeze protect tubing as needed. 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 guns and blanks per schedule below. 14-28B Add perf Schedule (Tie In Log Depths) 11978 - 12098 120’Run 3 12413 - 12513 100’Run 2 12568 – 12798 230’Run 1 ***Note the tie in log is 2’ shallower than reference log depths on the proposed schematic.*** 11.

Mud Program: • Well kill: 8.4 ppg brine. • Milling/drilling: 8.6 ppg PowerVis for milling window and drilling (572 psi over-balance). Disposal: • All Class I & II non-hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS 4 or Pad 3 at DS 6. • Fluids >1% hydrocarbons or flammables must go to Pad 3. • Fluids >15% solids by volume must go to GNI. • Fluids with solids that will not pass through 1/4" screen must go to GNI. • Fluids with PH >11 must go to GNI. Hole Size: • 3.25" from 10,790' MD to 14,167' MD. Liner Program: • 2-3/8", 4.7# STL, L-80, solid liner 9,680' MD to 14,167' MD. • A minimum of 17.5 bbls of 15.8 ppg cement will be used for liner cementing (TOC 11,240' MD). • The primary barrier for this operation: a minimum EMW of 8.4 ppg. - • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. Directional • See attached directional plan. Maximum planned hole angle is 95°, inclination at kick off point is 51°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 19,900' north. - • Distance to nearest well within pool — 35' (15-27A). Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole GR/CCL/RPM logs will be run. Perforating: • SWS 1.56" PJ, 6 spf perf guns, 1" CSH work string, & 2-1/16" CSH. • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Anti-Collision Failures • 15-28A fail major risk - no errors (parent well). • 15-27A fail major risk, pass minor risk - 1/200. • 15-28B PB1 fail major risk - no errors (parent well for drilling 15-28B). Hazards • Drill Site 15 is NOT an H2S pad. • Most recent H2S level on 15-16B is 36 ppm recorded on 2/6/2013. • The lost circulation risk in 15-28B is considered to be medium. - Reservoir Pressure • The reservoir pressure on 15-28B is expected to be 3,364 psi at 8,800' TVDSS. (7.35 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,484 psi. • An EMW of 8.6 ppg for this well will provide 572 psi over-balance to the reservoir. TrevorHyatt CC: Well File CTD Engineer Joe Lastufka 907-564-4627 Ferguson, Victoria L (DOA) From: Hyatt,Trevor <Trevor.Hyatt@bp.com> Sent: Wednesday, September 17,2014 8:40 AM To: Ferguson,Victoria L(DOA) Subject: RE: PBU 15-28B(PTD 214-135) Victoria, 15-27A is a producer that we will be shutting-in for the duration of drilling 15-28B. We will lock out 15-27A before we move onto 15-28B and not take the lock off until the rig is moved off. Because we will be shutting this well in during drilling, we have minor risked this well to 1/200 and it passes anti-collision. Trevor Hyatt BP Exploration (Alaska), Inc.
