History and current status: G-10C was a coil tubing sidetrack drilled in 2006 and completed with 950' of perforations in Z1 B. The initial gas and oil rates were 1.5mmcfd and 4000bopd. Within a few months gas rate increased to 20mmcfd and the oil rate dropped to 700 bopd. A CIBP was set in 12/12 to shut-in the toe. There are no additional wellwork options for this bore and the well is ready for sidetrack. Proposed plan: G-10D will exit from well G-10C by the Nordic 1 Coiled Tubing Drilling rig on or around November 1, 2015. The G-10D sidetrack will exit through the existing 3-1/2" tubing and 7" liner and kick off in the Shublik, and target Zone 1B and 2A reserves. The proposed sidetrack is a —3,250' Ivishak Zone 1 B/2A producer, which will access a —35 acre Z1A reserves target. The lateral will be completed with a 2-3/8" L-80 liner which will be fully cemented and perforated. This Sundry covers plugging the existing G-10C perforations via the G-10D liner cement job or a liner top packer if liner lap test fails (alternate plug placement per 20 AAC 25.112(i)). The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. )� G 04 Cohc G/r y r /(v y r4 �o/ Noy.; 1,1 rt (PCic" C(A.A p / !� " 7 'Mr/ 4t %9 lec(e651/991 -�r cJ!drill f4 O t/' r o f i 6� Me, p°d i - ,4 /i Pre-Rig Work(scheduled to begin October 1st,2015) 1.

This was a typo. There's no reason why they should be different. The correct value is 2470 psi. 2. The 74 sacks indicated on the PTD was incorrect. The correct value for 21 bbls is 102 sacks.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsible 1 The initial reviewer will check to ensure that the "Plug for Redrill" box in the Patricia or Steve upper left corner of Form 10-403 is checked. If the "Abandon" or "Suspend" ,------ / boxes are also checked, cross out that erroneous entry and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2 If the "Abandon" box is checked in Box 15 (Well Status after proposed Patricia or Steve work) the initial reviewer will cross out that erroneous entry and initial it on ---,- both 'both copies of the Form 10-403 (AOGCC's and operator's copies). Instead, then check the "Suspended" box and initial that change. Guy or Victoria The drilling engineers will serve as quality control for steps 1 and 2. (QC) 3 When the Stat Tech receives a Form 10-403 with a check in the "Plug for Jenni Redrill" box, she will enter the Typ_Work code "IPBRD" into the History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." 4 When the Stat Tech receives any Form 10-407, she will check the History tab Jenni in RBDMS for the "Intent: Plug for Redrill" code (IPBRD). If present and there is no evidence that a subsequent re-drill has been COMPLETED, the Stat Tech will assign a status of SUSPENDED to the well bore in RBDMS no matter what status is listed on the 10-407. The Stat Tech will also change the status on the 10-407 form to SUSPENDED, and date and initial this change. If the Stat Tech does not see the "Intent: Plug for Redrill" comment or code, she will enter the status listed on the Form 10-407 into RBDMS. 5 When the Form 10-407 for the redrill is received, the Stat Tech will change Jenni the original well's status from SUSPENDED to ABANDONED. 6 The first week of every January and July, the Stat Tech and one of the Jenni Geologists will check the "Well by Type Work Outstanding" user query in Patricia or Steve RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, they will also review the list of suspended wells for accuracy.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion 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 filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement 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. If you require any additional information, please contact me or my alternate, Gerald Murphy, at 659 -5102. Sincerely, Mehreen Vazir BPXA, Well Integrity Coordinator 0 • BP Exploration (Alaska) Inc.

IreM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. IreM 4b: TPI (Top of Producing Interval). IreM 8: The Kelly Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. ITEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). IreM 20: True vertical thickness. IreM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. IreM 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval).

This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659-3607 (pager). Sincerely, Daniel T.

Mud Program: • Well kill: 8.5 ppg b • Milling/drilling: .6 pg Flo Pro or biozan for milling, new Flo Pro for drilling. Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • All Class I wastes will go to Pad 3 for disposal. Casing Program: • 2 3/8", 4.6#, L- , ~ T-L fully cemented liner. Top of liner to be at 9,425' MD (8575ss). ~ • A minimum 13 is 15.8 ppg cement will be used for liner cementing. Note: The very short liner lap is designe provide room for a future sidetrack. A retrievable liner top packer will be installed-~' to seal the liner lap and cover squeeze hole in the 3'h" tubing. Well Control: .BOP diagram is attached. Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. / The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Max. planned hole angle is 92 deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property -13,600 ft. • Distance to nearest well within pool -1000 ft. (G-27) Logging • MWD directional and Gamma Ray will be run over all of the open hole section. MCNL log will be run across the cemented liner. Hazards • The maximum recorded H2S level on G Pad is 20 ppm (G-29 on 9/3/05). • Lost circulation risk is moderate. Reservoir Pressure • Res. press. is estimated to be 3200 psi at 8800'ss (7.0 ppg EMW). Max. surface pressure with gas (0.10 psi/ft) to surface is 2320 psi.
