Anticipated Surface Pressure:2,470psi (Based on 0.1 psi/ft. gas gradient) Last SI WHP:2250psi (Taken on 09/20/2022 Coil) Min ID:1.87” ID – nipple reducer @ 13,001’MD Max Angle:98 Deg @ 19,174’ Reference Log: PDC 24-July 2014 Brief Well Summary: July 2014 Rotary sidetrack completed with 1150' of Z1A perfs. The heel was intentionally left unperfed to allow for a future CTD kickout point. Elected to shoot this in January 2018 as well as shut-off the toe up perfs which were shot to bring in-situ lift to the well - results were positive (cut gas and increased oil), however, short lived as oil rate declined rather quickly . Nov 2019 added ~1,000' of 1A in the heal, with an orifice over the original perfs for insistu, initial POP -3,600 bopd. The lower perfs were isolated when the well gassed out. Objective: The objective of this procedure is to add two intervals of Z1AB perfs (14,564’- 14,704’ (140ft) and 14,330’ – 14,438’ (108ft) and isolate the current Z1 perfs. Procedure: Slickline 1.Pull 45KB POGLM patch from 2,979ft. Pull nipple reducer from 13,001ft. Coiled Tubing Notes: x Due to the necessary open hole deployment of Extended Perforating jobs, 24-hour crew and WSS coverage is required. x Note: The well will be killed and monitored before making up the initial perfs guns. 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. 2. MIRU Coiled Tubing Unit and spot ancillary equipment. 3. 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. o add two intervals of Z1AB perfs (14,564’- 14,704’ (140ft) and 14,330’ – 14,438’ (108ft) and isolate the current Z1 perfs. P Plug and Ext Adperf Procedure 18-11B PTD: 213-195 4. Bullhead 280 bbls of KWF, 8.4 ppg 1% KCl or 8.5 ppg 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 to top perf = 226 bbls b. 4-1/2” Tubing and Liner – 14,906’ X .0152bpf = 226 bbls 5. MU and RIH with drift BHA to resemble 4-1/2” CIBP. Run past 14,825ft ctmd and POOH. MU and RIH with logging tools and log OOH. 6. POOH and confirm good data. 7. RIH with 4-1/2” cast iron bridge plug and set at ~14,825ft. Pressure test to 500-psi 8. Freeze protect tubing as needed. 9. At surface, prepare for deployment of TCP guns. 10. 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 continuous hole fill taking returns to tank until lubricator connection is reestablished. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow. 11.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. 12. Break lubricator connection at QTS and begin makeup of TCP gunsand blanksperschedule below. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow. 18-11B Addperf Schedule *HES 2-7/8” Maxforce guns were used to estimate for this job. 3.047” gun swell 13. MU lubricator and RIH withperf gun and tie-in to coil flag correlation. Pickup and perforate interval per Perf Schedule above. POOH. c. Note any tubing pressure change in WSR. 14. 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. 15. Pump pipe displacement while POOH. Stop at surface to reconfirm well dead and hole full. 16. Review well control steps with crew prior to breaking lubricator connection and commencing breakdown of TCP gun string. Standing orders flow chart included with this sundry request.

It is primarily a Z1 producer with a toe up into zone 2A for in-situ gas lift. The well was initially perforated in the toe in Z1 and Z2A with an orifice set over 2A to allow a controlled amount of gas production in the toe for insitu lift. The well connected to gas and the following year the 2A perfs were blanked off, which resulted in shutting off competitive production (30,000 GOR) The plug was pulled 4 months afterwards and the well was a fulltime producer for the next 2 years. January 2018 a plug was set over the toe parts and 700' of 1A perfs were shot. Recently the well has started seeing sporadic on time due to approaching field marginals. The production liner still contains significant unperfed Z1A footage. The primary objective of this intervention is to isolate the perforations that have been open to flow since the well was drilled (believed to be contributing the HGOR fluid) with a packer/orifice assembly to provide insitue lift and perforate 1,200' of Z1A resulting in the well having a total of 1,900' of Z1A open to flow. The Z1A that will be open to flow does not appear to be as clean of quality of sands as the original perforations hence the increased footage. A packer/tailpipe assembly will set between the current perfs and the adperfs to provide the optionality of shutting off of the 700' of Z1A perfs shot in 2018 without needing to remove the patch in the tubing. A minimum of 1 00'spacing has been left inbetween the perforation intervals to allow for the future potential of retrofiting the liner with AICD's. A cement log will be run prior to evaluate the cement quality, there were losses observed and potential fault @ 14,497' during drilling. Job Sequence WBL Steps E. Townsend/C.

Reservoir pressure - BHP is expected to be -3300 psi (7.2 ppg) @ 8800' TVD. SBHPS has not been run since the B sidetrack was drilled in 2014. Maximum calculated surface pressure with gas (0.10 psi/ft) to surface is 2420 psi. A full column of 1% KCI (8.34 ppg) will provide a -467 psi static overbalance. 2. Fracture pressure - For the PBU main area the FG is estimated to be 0.65 psi/ft. This equates to 5,655 psi at 8,700' TVD, or 12.5ppg EMW.

However, before they could get the plug set excessive winds forced them to lay down the equipment. With the patch out,the well has TxIA communication and exceeded NOL with the inner annulus pressure reported to be 2300 psi. When the weather permits, slickline will be rigging back up to set a tubing tail plug and secure the well. Let me know if you have any questions.

This is an efficiency measure that should save time on these next few perf jobs. The next CTD well will be also using this string so it made sense to pick it up. Thanks, Jacob C.

A procedure was executed in September 2015 to blank off the in-situ gas at the toe of the well. This was designed to mimic a successful GSO on 18-21B. It successfully shut off 10 mmscf/d but since then the gas rates have risen. The blanking orifice was pulled and the gas rate did not change, thus a suspected failed orifice or packer. The GOR has continued to increase needing to be shut off to remain competitive. Scope of Work: The primary objective of this well intervention is to shut off the toe using a CIBP to ensure gas shut off and add 704 ft of perforations using service coil and the well work platform. Pre WWP work SL 1 Pull patch, pull nipple reducer, drift to deviation Proposed WWP Procedure: • MIRU WWP, BOPE and support equipment • MIRU CTU • Test BOPE with four preventers configured top down (annular, blind shears, 1.75" pipe/slips, mud cross and 2-3/8" x 3-1/2"VBR's, 1.75" pipe/slips). Test the blinds, VBR's, and pipe slip to 3500 psi and the annular to 2500 psi. • Drift and tie in run with GR/C L • Set CIBP at-18,700'MD • Perf-704ft • RDMO CTU and WWP Post WWP work SL 1 Reset and test nipple reducer FB 2 Assist SL, test nipple reducer EL 3 Reset bottom of patch SL 4 Reset top of patch with dummy valve installed.

The perforation intervention has been completed, however it remains to be seen if the well will naturally flow with the current configuration. The well will be actively monitored during this test, with the well to be immediately shut in if IAP exceeds 2,000 psi or the OAP exceeds 500 psi. At the conclusion of the test, the well will be shut to mitigate the annular communication. Please call with any questions. Thank you, Laurie Climer (.-I(i(';now ./(f(/.

There was a spike in the pressure to 1700 psi on 08/25/14 and 08/26/2014. Yes, after the well was shut in the IA pressure was at 1750 psi. The IA pressure has since been bled off. I have attached an updated TIO plot to show this. If at any time during the test the inner annulus pressure exceeds MOASP (2000 psi) the test will be terminated and the well shut in and IA pressure bled off. There will be constant monitoring of the inner annulus pressure during the testing period.

The sidetrack and workover was completed on 07/08/2014. The well was placed online using gas from an adjacent well to provide artificial lift down the inner annulus of 18-11B, as no artificial lift gas is available on drill site 18. The gas lift was only to be used to kick the well off, then it would be discontinued once the well was flowing on its own. Shortly after the well was placed on production it failed a negative liner lap test on 08/25/2014, and the well was placed Under Evaluation. The gas lift valves were then pulled and were found to be flow cut. We suspect that the gas from the adjacent well used to provide artificial lift was wet and this caused the flow cutting of the valves. Dummy gas lift valves were then installed in stations#4 and #6 and a MIT-IA failed. A subsequent leak detection log found a leak in station #6 (upper most station) on 09/02/2014. We suspect the mandrel is flow cut also. A tubing tale plug was then set and a CMIT-TxIA passed to 3000 psi on 09/03/2014. BP would like permission from the AOGCC to flow the well without gas lift for a period of up to 14 days to determine if the well will flow on its own. If the well does flow without gas lift then a tubing patch will be set across station#6 to repair the tubing x inner annulus communication. If the well will not flow options such as patching station#6 and nitrogen lifting,gas lift redesign, or a rig workover will be evaluated. Copies of the TIO plot and wellbore schematic are attached for reference. 2 Please let me know if you need additional information.

It was then worked over in 1990. The well sidetracked by a coiled tubing rig in 11/2009. The well produced for 7 months before the water production increased from < 100bwpd to 3000bwpd in July 2010. It was confirmed that the water was from the Cretaceous formation. Reason for sidetrack: 18-11A is a non-operable well due to production casing and tubing leaks. A rig workover of the current well would be very risky due to scaling caused by crossflow of the Cretaceous with the Ivishak. ✓ Therefore, this well is not operable and has no remaining value. Diagnostics logs (SCMT and Gravel Pack RST) were run to determine if any fill was present below the production casing leak. Both logs indicated solids accumulation over the interval between 10,162'— 10,436' MD. Sidetrack Plan: The existing 18-11A wellbore will be abandoned with a lateral cement plug set above the reservoir. The new wellbore will be mechanically isolated from 18-11A by an EZSV plug at—2700'. Casing whipstock will be set over EZSV and sidetrack will be performed out of 9-5/8" cased hole. An 8 1/2' intermediate hole is proposed to be drilled to the top of Sag River to be then cased with a 7" 26# L-80 string to surface. A 6 1/8" hole will then be drilled from the bottom of the 7" targeting Ivishak formation. The production section is to be completed with 4 '/2' liner systems with top of cement planned to top of liner depth. The well will be perforated across Ivishak Zone 1A . and tied to surface with 4-1/2" tubing string. MAASP: 3015 psi—Ivishak 21TS Pre-Rig Work: (scheduled to begin January 15, 2014) 1. Perform diagnostics to determine if any solid accumulation present around the tubing under the production leak. Determine the free point(completed) 2.

Well Control A. Intermediate Hole - The section has been split in 3 sections. Normally pressured formations will be drilled with lower mud weight that will provide sufficient overbalance. Mud density will be raised prior drilling into potentially overpressure Cretacious formations. The third section of the well will require the highest mud weight to overbalance Put River formation as well keep Kingak shale formation stable. B. Production Hole - The Sag River and Ivishak formations in this area are expected to be under-pressured at 7.5-8.0 ppg EMW. This interval will be drilled with —8.5-8.9 ppg reservoir drill-in fluid. II. Lost Circulation/Breathing A. Intermediate Hole — lost circulation is moderate. Lowest possible ECD will be used for preventing losses as well as good drilling practices (short trips, rotation, etc.). Breathing risk is high and any uncertainty shall be treated as per well control procedures. B. Production Hole—the risk of lost circulation in this hole section is low. III. Kick Tolerance/Integrity Testing A. With the planned mud weights, the kick tolerance for the intermediate section is expected to be in the range of 11-40 bbls. B. Infinite kick tolerance for production hole section with planned mud weights and predicted fracture gradient at the shoe C. Integrity Testing Test Point Test Depth Test type EMW(Ib/gal) 9-%" window 20'-50' from the 9-%" window LOT 11.1 minimum 7" shoe 20'-50' from the 7" shoe FIT 9.8 minimum IV. Hydrogen Sulfide DS-18 is not an H2S site. V. Faults 18-11B well will not intersect any mapped faults. There may be some small, poorly defined D to S faults in the lower Colville (CM1), at about 12,800 MD. VI. Anti-Collision Issues Following wells do not pass major risk criteria L2-07A. t_2 21A, 18 26B CONSULT THE DS-18 PAD DATA SHEET AND THE WELL PLAN FOR ADDITIONAL INFORMATION . .

P&A plan change:Originally,we were planning to run a USIT log to determine top of cement behind 9-5/8" casing. We were able to find old records and qualify our cement job based on volumetric calculations(this process was internally risk assessed and approved by our leadership including Alaska VP Wells).The records indicate that the top of the cement column is located at a sufficient distance above the reservoir preventing any potential cross-flow of fluids between different formations.The only change to the P&A plan is the fact that we will not run a USIT log.We are still going to place a 1000ft balanced cement plug into the 9-5/8" casing string. 2. Directional plan/shut in wells:We have been able to optimize our directional plan for the 8.5" intermediate section in such a way that L2-21A and 18-26B wells pass the anti-collision risk and do not require to be shut in. The production hole section did not undergo any changes, i.e.our drilling targets are still the same. 3. Cut&pull 9-5/8"casing:we were planning to cut and pull part of 9-5/8" casing and run 7" liner to surface.We determined that it would be much more efficient to avoid cut&pull of 9-5/8"casing and run 7"string as a liner. I have attached a proposed well schematic for the easy of understanding. 1 Y . Please let me know if you would like to discuss any of the changes mentioned above or need me to send some more info.

Date: December 12, 2013 Re: 18-11B Permit to Drill Well History: This well was originally completed in 1984. It was then worked over in 1990. The well sidetracked by a coiled tubing rig in 11/2009. The well produced for 7 months before the water production increased from < - 100bwpd to 3000bwpd in July 2010. It was confirmed that the water was from the Cretaceous formation. a Reason for sidetrack: 18-11A is a non-operable well due to production casing and tubing leaks. A rig workover of the current well would be very risky due to scaling caused by crossflow of the Cretaceous with the Ivishak. Therefore, this well is not operable and has no remaining value. Diagnostics logs (SCMT and Gravel Pack RST) were run to determine if any fill was present below the production casing leak. Both logs indicated solids accumulation over the interval between 10,162' — 10,436' MD. Sidetrack Plan: The existing 18-11A wellbore will be abandoned with a lateral cement plug set above the reservoir. The new wellbore will be mechanically isolated from 18-11A by an EZSV plug at —2700'. Casing whipstock will be set over • EZSV and sidetrack will be performed out of 9-5/8" cased hole. An 8 '/2" intermediate hole is proposed to be drilled to the top of Sag River to be then cased with a 7" 26# L-80 string to surface. A 6 1/8" hole will then be drilled from the bottom of the 7" targeting Ivishak formation. The production section is to be completed with 4 '/2" liner systems with top of cement planned to top of liner depth. The well will be perforated across Ivishak Zone 1A and tied to surface with 4-1/2" tubing string. MAASP: 3015 psi — Ivishak 21TS Pre-Rig Work: (scheduled to begin January 15, 2014) 1. Perform diagnostics to determine if any solid accumulation present around the tubing under the production leak. Determine the free point(completed) 2.

Well Control A. Intermediate Hole - The section has been split in 3 sections. Normally pressured formations will be drilled with lower mud weight that will provide sufficient overbalance. Mud density will be raised prior drilling into potentially overpressure Cretacious formations. The third section of the well will require the highest mud weight to overbalance Put River formation as well keep Kingak shale formation stable. B. Production Hole - The Sag River and Ivishak formations in this area are expected to be under-pressured at 7.5-8.0 ppg EMW. This interval will be drilled with —8.5-8.9 ppg reservoir drill-in fluid. II. Lost Circulation/Breathing A. Intermediate Hole — lost circulation is moderate. Lowest possible ECD will be used for preventing losses as well as good drilling practices (short trips, rotation, etc.). Breathing risk is high and any uncertainty shall be treated as per well control procedures. B. Production Hole—the risk of lost circulation in this hole section is low. Ill. Kick Tolerance/Integrity Testing A. With the planned mud weights, the kick tolerance for the intermediate section is expected to be in the range of 11-40 bbls. B. Infinite kick tolerance for production hole section with planned mud weights and predicted fracture gradient at the shoe C. Integrity Testing Test Point Test Depth Test type EMW(lb/gal) 9-%" window 20'-50' from the 9-%" window LOT 11.1 minimum 7" shoe 20'-50' from the 7" shoe FIT 9.8 minimum IV. Hydrogen Sulfide DS-18 is not an H2S site. V. Faults 18-11B well will not intersect any mapped faults. There may be some small, poorly defined D to S faults in - the lower Colville (CM1), at about 12,800 MD. VI. Anti-Collision Issues Following wells do not pass major risk criteria L2-07A.

The reasoning behind not applying gas pressure to surface is because it is too conservative in the case of this well. In an unlikely case of taking a gas kick the surface pressure will continue to rise (if no action is taken) to the point when the weakest formation will fracture, i.e. we will never see gas pressure to surface in any case. Most likely value of fracture gradient of the sand formation below the casing shoe is — 12.48 ppg. The calculation method that I used considered the highest predicted Shale fracture gradient- Brumfield model at the shoe + 2ppg safety factor which in turn resulted in pressure gradient of 16.88 ppg (this is higher than Overburden gradient). Substracting gas gradient(0.1 psi/ft) from the highest possible fracture pressure at shoe would result —2061 psi at surface. In other words, the MPSP will not exceed this number in any scenario with the given fracture gradient values. If I consider simply extrapolating gas gradient to surface it would require excessively high casing testing pressure, i.e. normally our test pressure = 1.2 x MPSP. This would potentially compromise the design of this well as the required pressures would exceed 4,000 psi. Considering that a section of 9-5/8" casing will be cut&pulled we don't want to apply such a high pressure to the 13-3/8" string which had not been tested to that value in the past. Please let me know if you need any further clarification on this issue.
