AirP Well Name: S-110A Well Type: Injector Current Status: Oil Producer Shut-In Request: P&A-Well Prep f/Rotary Sidetrack MIT-IA passed to 4000 psi (10/18/13) MIT-OA fail to 2000 psi (10/18/13) Well History: S-110 was completed in 2001 and sidetracked in 2011. The S-110A sidetrack ended with BHA getting stuck across the casing shoe due to A sands differential pressure. The current well has no utility as is, so the best utility of this wellbore is a sidetrack into C only sands. Reason for P&A/RST: All well work options have been pursued on recovering the BHA, but to no avail. A . rig sidetrack is the only remaining option for this well. Establish an injectioninpoint to the north of S-109 for waterflood/MI management. iCty� "` f* Pre-Rig Work: 1. Collect S-109 bottom hole pressure via downhole gauge in mid-December 2013 2. Shut in offset injectors S-112i and S-123i a minimum of four weeks prior to spud to ensure pressure no greater than 3750 psia @ 6700' TVDss (10.8 ppg MW equivalent). 3. Set a downhole plug in S-124 at minimum 5000' MD and fill tubing and IA with kill weight fluid. (TCR mitigation) 4. Maintain production from S-109 as much as practical to continue drawdown of reservoir pressure. 5. Collect 5-110A static bottom hole during P&A operations 6. Run coil down to 7975' MD and lay a 10 BBL cement column up to 7699' MD (packer depth). 7. Perform tubing punch at-7695' MD 8. Swap well to 9.8 ppg brine 9. Pump 84 BBL cement up to 5225' MD (650' TVD above top SB-Na) 10. Pressure test tubing and IA to 3500 psi 11. Drift and tag TOC with e-line 12. Perform e-line jet cut on tubing at 3200' 13. CMIT and TXIA to 3500 psi 14. Prior to rig move, shut in wells in Parker 273 rig shadow(S-119, S-109, S-102, S-100, S-101, and S- 115). These may be brought back into production if an ESD is installed. 15. Remove S-110B well house for preparation in moving rig on. Removal of adjacent well house railing could be necessary. Rig Operation: 1. MIRU Parker 273 2. Nipple down tree and adapter flange 3.

All, Injector S-110A(PTD#2111290) has been shut in since August 2010 for a rig sidetrack. The sidetrack began in December of 2011, but was not completed due to drilling complications. Subsequent well work has demonstrated low injectivity to the reservoir. The well was due for an AOGCC MITIA on 09/09/2012, but was never placed on injection to perform the test. The well is reclassified as Not Operable and will be placed on the Quarterly Not Operable Injectors Report. The well is being reevaluated as a sidetrack candidate. Copies of the TIO plot and wellbore schematic are included for reference. Please call with any questions.

It is essentially a downhole choke. If a RWO is planned to fish it out then a Sundry would be required. Regards, Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) From: Brown, Matt(CONTRACT PROFESSIONALS) [mailto:Matt.Brown@bp.com] Sent: Tuesday, August 14, 2012 9:54 AM To: Schwartz, Guy L(DOA) Cc: Spence, Clint]; West,Taylor; Sidoti,Todd Subject: S-110A coil operations Guy, Attached is a diagram showing well S-110A post-coil operations. The coil is currently stuck at about 7913'. We plan on cutting the coil at 7620'and leaving the coil fish in the well. Currently, we can pump down the coil but not the backside. After we cut the coil,the plan is to rig down the CTU,dummy off the GLVs and prep the well for injection. The injected fluids will go through the coil fish and BHA. Please feel free to contact me with any questions.

We were actually able to fish the source with slickline tools through the circulation sub. The circulation sub has only a 1.25" Drift ID, but we were able to pump 1.30" OD slickline tools through the ID restriction and remove the source. Our current plan forward is to continue fishing the BHA in an attempt to achieve enough open hole to kick-off a cement plug and re-drill the production interval below the 7" casing shoe. If we are able to do this, we will not need a Sundry and will be able to use the existing Permit-to-Drill. Details of the exact plan forward are being worked. There is a good chance the interval will be drilled at a more shallow TVD through the Kuparuk with higher dogleg severity in the build section and different mud weights. These changes will be passed on to you for approval once the plan is worked in further detail. We appreciate your help this weekend in providing verbal approval for P&A of the source, and are glad that we did not end up needing to use it.

After 12.3 ppg kill weight fluid was circulated around the well and confirmed dead, we found our BHA was differentially stuck 200 ft outside the 7" casing shoe. We have a circulation sub near the top of the BHA with a 1.25" ID. This ID restriction has made it very difficult to fish the source. The fishing tool for the source will not drift through the circulation sub. Additionally, Schlumberger does not have 1"tools to perform a back-off below the circ sub with string shot. We have attempted to use 1"tools from a company called Pollard out of Kenai, but have not been able to get the string shot to fire when mixed with Schlumberger Wireline tools. We have a few more fishing options, but it is becoming increasingly likely that we will be forced to plug back the production hole with the source left in hole. I have two questions: What do I need to submit to the AOGCC assuming we leave the source downhole?Also, what do I need to submit if our plan forward includes abandonment of both the production interval and the intermediate interval to perform a 7"cut and pull operation to re-drill? I believe we will still fall under the existing Permit-to-Drill if we cut and pull to redrill the well, however, do I need to submit a Sundry for the current wellbore?

Operational Description Leading up to Well Control Event: Drilling ahead at 8174'MD, when the driller observed a 10% increase in flow. He picked up off bottom to flow check the well which was confirmed to have a slight trickle flowing from wellbore. Well was shut in and notification given. - BOPE Used and Reason: Annular preventer used to shut-in well per BP shut-in procedures. v- Is a BOPE Test Required after use ( Yes/ No ): If no, why? Test will be required. 24 hour notice required to NS AOGCC Inspectors prior to testing BOPE components. Plan Forward: Circulated bottoms up with Drillers Method and evaluated results. It was confirmed there was no gas in the backside with zero gain or loss in pits. A second bottoms up was circulated thru the choke to prevent freeze up while conferring with the pad operator And the Anchorage ODE in regards to potential injectors causing formation charging. No gas was observed on the second circulation with both shut in pressures the same. Allowed both SIDPP and SICP to build and stabilize to their highest value, staying well under recent FIT. Bled off 1/2 bbl. thru choke and allowed pressures to build and stabilize while recording pressures every minute. Both pressures built back to their previous shut in highs. Additional Comments: Suspect charging of reservoir due to injector. - Currently holding pressure on choke while adjacent injectors are shut in and freeze protected. - Evaluate options with Anchorage team. Both shut in casing/DP pressures stable and holding.

Our wellsite leaders have informed your slope based guys that we have spent a significant amount of time fighting tight hole and cold weather which caused our stand pipe to freeze up during the 7" intermediate casing run. We have currently managed to get casing to bottom and we are close to being ready to cement, however, there is some chance that the cement job will not be completed prior to midnight tonight to start our BOPE testing. We are making every effort to ensure we can lay down our landing joint after the cement job prior to midnight, however, we would like to provide notice that this may extend slightly past midnight.

Normally we would pump a couple of barrels of old mud down the OA every -1 hour to keep it open and clear of channeled cement and then pump the diesel once cement has gained some compressive strength. If temperature remains below-40 deg F, it may be necessary to continue to pump small amounts of mud down the OA to ensure it remains open. If extended time passes and a freezing annulus becomes a concern, the frequency of injection will reduce significantly, however, the volume may need to increase to ensure fluids in the OA do not freeze. Fluid volumes will be kept to a minimum and none of the injected fluid is meant to be used as a disposal method. With your approval we would like to proceed with this plan assuming temperatures remain below-40.

We had very good cement isolation between both the Kuparuk/Schrader and Schrader/Ugnu. The original USIT log from 2001 was performed a little too early after cement was in place and was most likely logging cement with very low compressive strength. We did involve global experts both from BP and SLB in interpretation of the new log and isolation of the reservoirs was agreed unanimously.

Glad you guys got the casing out. I assume you didn't do any shoot and sqz cement in the annulus below the casing cut. Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) From: Honas, Kristopher [mailto:Kristopher.Honas@bp.com] Sent: Friday, January 20, 2012 12:00 PM To: Schwartz, Guy L (DOA) Subject: S-110A Update and Minor Mud Weight Change Guy, About two weeks ago we had discussed the potential suspension of operations on S-110A due to a USIT log indicating cement in the OA, preventing a casing cut and pull. We did not end up deciding to move off S-110 and we were able to get the 7" casing cut and pulled. It took multiple cuts and a bit of jarring, but ultimately we have been able to continue on with operation as planned in the original drilling permit. I'm emailing you today to let you know that we plan to use only a 10.5 ppg mud to reach TD of the intermediate interval top setting the Kuparuk. The current permit to drill indicates that we will weight up to 10.8 ppg. The heavier mud was initially planned for wellbore stability through the HRZ and was not necessary for well control. The HRZ in this particular area is only —10 ft TVD. We have experience in the 1/20/2012 S-110A Update and Minor Mud Weight Change Page 2 of 2 area drilling the HRZ at our planned inclination and Azimuth with the lower mud weight. 10.8 ppg was being ultra conservative for shale stability. A 10.5 ppg mud weight will reduce ECD and the potential of lost circulation &/or wellbore breathing in the Colville and still provide adequate overbalance. We did a leak off test at the window and achieved a 15.5 ppg LOT. The 10.5 ppg mud weight provides a kick tolerance of greater than 50 bbls. With your approval we would like to make this minor change to the drilling program.

Honas, ODE Date: September 27, 2011 Re: S-110Ai Sidetrack Permit to Drill The planned S-110Ai rotary sidetrack is currently scheduled to be drilled by Doyon 14 beginning November 15th, 2011. The planned sidetrack is a horizontal injection well designed to replace the original S-110 wellbore and support production in the S-109 Kuparuk producer. The maximum anticipated surface pressure from the Kuparuk with a full column of gas from TD to surface is —2785 psi (assumes 9.9 ppg as max pore pressure). This well will be drilled by Doyon 14 using their 5000 psi four preventer BOP stack(3 rams and an annular). The BOP rams will be tested to 4000 psi and the annular will be tested to 3500 psi. The sidetrack plan for S-110A includes the following: 1. The pre-rig well work will include: a. Cement P&A of the perforations in the S-110 Kuparuk injector with coil b. A tubing cut at—8155' MD. 2. Move in Doyon 14 and pull the 3-1/2"tubing from —8155' MD. 3. Run a USIT log to determine cement isolation behind 7" intermediate casing. 4. Complete the S-110 P&A based on USIT results using one of the following options: a. Poor cement quality behind 7"casing: Two cement plugs as depicted in the de-complete schematic with perforations to circulate cement into the annulus. b. Good cement quality behind 7" casing: Set a continuous cement plug on a cement retainer extending from a minimum of 500 ft below the SB_OBf base to a minimum of 500 ft above SB_Nb top. rift The cement plug(s) from either option will be pressure tested and mechanically tagged. 5. Cut 7" casing —20 ft inside surface casing shoe and set 9-5/8" EZSV plug near base of 2nd 9-5/8" casing joint. 6. Set a Whipstock on the 9-5/8" EZSV bridge plug. Mill out and perform an FIT. 7. Drill 8-3/4" hole to top of the Kuparuk, run and cement a 7" casing string. 8. Drill out 7" casing shoe and perform FIT. Continue to drill 6-1/8" horizontal production hole to TD. 9. Run a 4-1/2" solid production liner with multiple swell packers for zonal isolation. 10. Run a 4-1/2"tubing string which will "sting" into the 4-1/2" production liner top. 11. Rig down and move off well. ;s ,fin A planned well summary is attached along with directional plan and proposed completion diagrams.

Sit6 -Pow bav4_ 7-sow S-11 OA PTD Page 10 9/27/2011 S-110A Drilling Critical Issues POST THIS NOTICE IN THE DOGHOUSE I. Well Control / Reservoir Pressures: A. Intermediate Hole: Overpressure in the Colville below Fault #1 is expected to be 10.2 ppg with maximum potential pressure of 10.4 ppg. Mud weight must be increased to a minimum of 10.5 ppg prior to crossing the fault. Note: gas cut mud has been commonly encountered through the Ugnu. B. Production Hole: The Kuparuk is anticipated to be pressured to 9.9 ppg based on a static bottom hole pressure survey in the S-110 parent injection wellbore (May 2011). S-110 has been shut in since this time. A pre-rig bottom hole pressure survey should confirm pressure less than 9.9 ppg prior to drilling the interval. Planned drilling fluid density should be over 10.2 ppg in the production interval to provide adequate trip margin. II. Lost Circulation/Breathing A. Intermediate Hole: Breathing and/or lost circulation is a possibility due to the shallow KOP on this well, fault crossing in the Colville, and 10.8 ppg drilling fluid required for wellbore stability in the HRZ. 10.8 ppg is approximately 0.3 ppg over the target mud weight to help prevent breathing. Fault #1 is crossed at-7481 ft MD and has 30 ft of throw. B. Production Hole - A single fault crossing is planned at -9990 ft MD with 30 ft of throw. The planned well path crosses perpendicular to the fault plane and lost circulation is not considered a high probability. III. Kick Tolerance/Integrity Testing A. With the planned mud weights, the kick tolerance for the intermediate section is 25 bbls, and the production section is infinite. If planned FIT values are not achieved, do not drill ahead without risk assessment and proper authorization. All kick tolerances are calculated based on a 0.5 ppg kick tolerance over likely pore pressure. IV. Integrity Testing Test Point Test Depth Test type EMW(lb/gal) 9-%"window 20'-50'from the 9-%"window FIT 12.6 ppg 7"shoe 20'-50'from the 7"shoe FIT 10.8 ppg minimum 12.0 ppg target V. Hydrogen Sulfide A. As S-Pad is considered an H2S site, refer to the ADW "Hydrogen Sulfide" SOP for the appropriate operational guidelines. The max recorded H2S readings on the pad were 300 ppm in S-201 Feb. 2010. S-119 and S-109 (closest wells at surface) recorded 16 ppm and 12 ppm. VI. Faults Formation Fault Encountered MD Intersect ND Intersect Est.Throw Throw Uncertainty Direction Fault#1 -Lower Colville Shale 7600' -6360 30' West +/-100' Fault#2-Kupaurk C Sand, 9990' -6860 30' West +1-100' horizontal section Fault#2 throw decreases to the south;the southern extension of this fault was penetrated in S-109 at 10,313'MD with 10' throw and no losses reported. Isolation of this fault in S-11 OAi is critical to prevent possible MBE between 5-110Ai and S- 109. Fault#1 vertical tip out below S-110. No fluid losses reported. VII. Anti-Collision Issues A. There are no anti-collision issues. All off-set wells pass Major Risk analysis. The closes approaches (center-center) are S-121 and S-124 at just over 70 ft. This occurs near KOP.

I apologize for not having this with the original submittal of the application. If this document does not meet the needs of an AOR please let me know and I will update it with any additional information required. Thank you, Kristopher Honas BP Rotary Drilling Engineer Desk: 907-564-4841 Cell: 907-268-0891 Kristopher.Honas@bp.com From: Schwartz, Guy L(DOA) [mailto:guy.schwartz@alaska.gov] Sent: Friday, September 30, 2011 11:40 AM To: Honas, Kristopher Subject: S-110A Sidetrack Kristopher, I am reviewing the PTD for S-110A(PTD 211-129) and see that there is no a Area of Review(AOR) included with the permit as required by 20 AAC 25.402 (C)(15) . Even though this is an approved Injection well (S-110) the new BHL is moved significantly away from the original wellbore so a 1/4 mile review will need to be done along the new horizontal well path. Attached are some guidelines.... There may not be any wellbores within '/4 mile of the lateral but a check of any abandoned or old P&A wells needs to be done. Regards, Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) 10/4/2011 by 0 S-110A Area of Review S-110Ai is a horizontal well with planned injection through the Kuparuk. The following three wellbores are within 1/4 mile of the planned S-110A wellbore from the top of the Kuparuk at 6715 ft TVDss (8036 ft MD) through TD of the S-110A lateral at 11,747 ft MD. The primary cement jobs for each wellbore and current well status are provided. 1) S-41 — Includes S-41A, S-41 L1, S-41AL1, and S-41 PB1 which all share a common 7" intermediate casing string through the interval of interest. a) Closest center-to-center distance: 1143 ft at a depth of 8715 ft MD along the S-110A directional plan 13. This is in the S-110A horizontal interval within the Kuparuk formation. b) Well Status: producer with two active horizontal laterals. May potentially be converted to an injection well in the future. c) Intermediate Casing: 7", 29#, L-80, BTC-M crossed over to 7", 26#, L-80, BTC set at 12,003 ft MD (8934 ft TVD). d) Intermediate Cement: 357 sacks of premium lead at 11.0 ppg and 289 sacks of premium tail at 15.7 ppg. The planned top of cement was 500 ft above the Ugnu formation. The operation summary dated March 8, 1996 - March 9, 1996 does not indicate any lost circulation occurred during the cement job. 2) S-109 a) Closest center-to-center distance: 1254 ft at a depth of 11,442 ft MD along the S-110A directional plan 13. This is in the S-110A horizontal interval within the Kuparuk formation. b) Well Status: active producer in the Kuparuk formation. Will be supported by S-110Ai injection. c) Intermediate Casing: 7", 26#, L-80, top set in the Kuparuk at 7820 ft MD. d) Intermediate Cement: 131 bbls of 12.0 ppg lead, 19 bbls of 15.8 ppg Class G tail. The planned top of cement was the UG4A. The daily drilling report dated January 7, 2003 does not indicate any losses occurred during the cement job. 3) S-110— Parent Wellbore a) Closest center-to-center distance: 592 ft at a depth of 8530 ft MD along the S-110A directional plan 13. This is in the S-110A horizontal interval within the Kuparuk formation. b) Well Status: shut-in and awaiting plug and abandonment for the planned S-110A sidetrack. c) Intermediate Casing: 7", 26#, L-80 set at 8773 ft MD in the Kuparuk formation. d) Intermediate Cement: 165 bbls of cement bringing planned TOC into the Ugnu, however, cement bond log indicates poor cement isolation. Planned plug and abandonment operations for the wellbore include a USIT log to confirm cement isolation between the Kuparuk/Schrader, and the Schrader/Ugnu. The 7" casing will be perforated and cement plugs will be set behind casing if isolation is not confirmed by the USIT log. Reference the S-110A Sundry and Permit to Drill application for details.
