Anticipated Surface Pressure:2,360 psi (Based on 0.1 psi/ft. gas gradient) Last SI WHP:800 psi (Taken on 7/29/25) Min ID:1.745 @ 9,482 MD Max Angle:98 Deg @ 11,898 MD, 70 Deg at 9,750 MD Brief Well Summary: 05-22B was sidetracked in Oct 07. The well is a gravity drainage Z1A/B lateral. The well is currently uncompetitive after a plug mill. We would like to plug the 1B section and add additional 1A perfs in the heel. Objective:Plug the 1B section and add remaining unswept Z1A heel. Procedure Coiled Tubing 1. MU drift BHA with GR/CCL in 1.69 carrier, drift to 10,600ft. Note: 1.74 ID at 9,482 ft (liner top seal assembly). 2. Correlate with attached log information. a. Correct flag and send to OE for confirmation. 3. RIH and set 2-3/8 CIBP at 10,600ft. Coil Extended Perforating Notes: Remote gas monitoring for H2S and LELs are required for Open Hole Deployment Operations Due to the necessary open hole deployment of Extended Perforating jobs, 24-hour crew and WSS coverage is required. 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. 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. Bullhead 1.2x wellbore volume ~130 bbls 1% KCL/SW down tubing. 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 = 104 bbls b. 4-1/2 tubing 3,007 X .0152 bpf = 45.7 bbls c. 3-1/2 tubing 3,007 9,448 X .0087bpf= 56 bbls d. 2-3/8 liner 9,448 10,050 (top perf) X .00387bpf= 2.3 bbls Extended Add Perfs 05-22B PTD: 207-126 3. At surface, prepare for deployment of TCP guns. 4. 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. 5.*Perform drill by picking up safety joint with TIW valve and space out before MU guns. Review standing orders with crew prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety joint and TIW valve have been spacedout, keep the safety joint/TIW valve readily accessible near the working platform for quick deployment if necessary. e.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. 6.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 Use 1.56 Millennium guns or similar (1.76 swell in liquid) Perf Interval (tie-in depths)Total Gun Length Weight of Gun (lbs) Run #1 9,830 - 9,990 160~640 lbs (4 ppf) 7. 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. 8. After perforating, PUH to top of liner or into tubing tail to ensure debris doesnt fall in on the guns and stick the BHA. Confirm well is dead and re-kill if necessary before pulling to surface. 9. Pump pipe displacement while POOH. Stop at surface to reconfirm well is dead. Kill well if necessary. 10. Review well control steps and Standing Orders with crew prior to breaking lubricator connection and commencing breakdown of TCP gun string. 11. Ensure safety joint and TIW valve assembly are on-hand before breaking off lubricator to LD gun BHA. 12. RDMO CTU. 13. Turn well over to Operations POP.

The corrosion inhibitors engineered to prevent water from entering the annular space and causing external c 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 fi ling and volumes of corrosion inhibitor used in each conductor. As per previous agree ent 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.

It would appear that there was a typo when the liner detail was entered in the operations summary. The numbers in the ops summary on October 20 just didn't "add up° to what is given for October 21, the drawing or what you have on the 407. Hence, my question. Thanks for the reply.

Okay? Terrie From: Maunder, Thomas E (DOA) [mailto:tom.maunder@alaska.gov] Sent: Wednesday, December O5, 2007 6:56 PM To: Rixse, Mel G Cc: Hubble, Terrie L Subject: 05-22B (207-126) Mel, I am reviewing the completion report for the subject well and have a question. On the report for October 20, the overall length of the liner is given at 2501.21'. However, the open hole at the time was 3305'. On the report for October 21, the shoe depth is given as 12917' and the TOL at 9482' indicating 3435' of casing was run. Could you reconcile the numbers? Thanks in advance.

(5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to log this well. (6} Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance Sub (Inner and Outer Downhole Pressure, Vibration and Downhole Weight on Bit), a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor and an Ultra Slim Resistivity Sub. (7) Data presented here is final and has been depth adjusted to a PDC (Primary Depth Control) log provided by Schlumberger GR CNL dated 02 Jan 2007 per Mike McTeague with BP Exploration (Alaska), Inc. (8) Tied to DS05-22 at 8809 feet MD (8427.2 feet TVDSS). (9) Baker Hughes INTEQ runs 1 through 8 were unsucessfull attempts to mill and kickoff from the first whipstock set at 9689 ft. MD (8899.8 ft. TVDSS) (10) Baker Hughes INTEQ runs 9 and 10 were used to set new whipstock and mill window. (11) The sidetrack was drilled from 05-22 through a milled window in a 7 inch dual string liner. Top of window 9607.6 ft.MD (8868.3 ft.TVDSS) Bottom of window 9614.6 ft.MD (8871.2 ft.TVDSS) (12) The interval from 12886.6ft to 12917 ft. MD (8978.8 ft. to 8979.4 ft. TVDSS) was not logged due to sensor bit offset. (13) The resistivity interval from 9615 ft. to 10736ft. MD (8871.4ft to 8953.3 ft. TVDSS) was ream logged in Run 11, 50 hrs. after drilling. (14) The resistivity interval from 12053 ft. to 12917 ft. MD (8973.3 ft. to 8979.4 ft.
