History and current status: 14-11A was a Zone 4 producer drilled and completed in 2005. The 14-11AL1 Zone 4 lateral was added in 2010. The 14-11AL1 leg encountered several faults that brought water into the parent well and made the laterals uncompetitive. All wellwork options have been exhausted and the well is no longer competitive. Proposed plan: 14-11B will exit from well 14-11A by the Nordic 1 Coiled Tubing Drilling rig on or around August 1st, 2015. The 14-11 B sidetrack will exit through the existing 4-1/2" liner and kick off in the Shublik, and target Zone 4 reserves. The proposed sidetrack is a -2,600' horizontal Ivishak Zone 4 producer, which will access a —33 acre reserves target off of drillsite 14. The lateral will be completed with a 3-1/2" X 3-1/4"X 2-7/8" chrome liner which will be fully cemented and perforated. This Sundry covers plugging the existing 14-11A and AL1 perforations and slotted lienr via the 14-11 B liner cement job or a liner top packer set post rig with slick line 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. . celer,'0, to t.'1/dof rte /ctriai the /4 74f--- well V Icif /f 0 BO P,D w ` c 95w�/.c. 0v/7 Iffer p iu feral god ,0A dropfe, 70 < JO/of/ q wi ,-- Or/� e t(c,e / off ?,7%). 14 f bt•e tl 141 kid' /Ptit votive_ r5 cure/1T hortoM4o/e /0ce`0', ((u,, y i-4, wc// ��ov od a1/ow Cor ;Prave1 1eCOv �Gl -fir `��� : � � pD�t� Oft D-¢ rhe pc Pre-Rig Work(scheduled to begin July 1St, 2015) 1.

(i': . 1 Sundry Application Plug for Re-drill Wells Work Flow This process is used to identify wells that are suspended for a very short time prior to being re-drilled. 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 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.

Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item la: Classification of Service Wells: Gas Injection,Water Injection,Water-Altemating-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. Item 4b: TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. 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). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: 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). Item 27: Method of Operation: Flowing,Gas Lift,Rod Pump,Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain). Item 28: Provide a listing of intervals cored and the corresponding formations,and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 MC 25.071. Item 30: Provide a listing of intervals tested and the corresponding formation,and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 MC 25.071.

(TOC 10,600'MD) • 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 2,500 psi. Directional • See attached directional plan. Maximum planned hole angle is 90 deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property line— 15,160' South • Distance to nearest well within pool — 1980' (14-10 producer) Anticollision Summary • No anti-collision issues. Logging • Resistivity, MWD directional and Gamma Ray will be run over all of the open hole section. • A cased hole GR/CCL/CNL log will be run. Hazards • The maximum recorded H2S level on DS 14 is 590 ppm on well 14-21 (07-16-1995). • Lost circulation risk is high. One fault crossing expected between 11,400'— 11,600'.

Pre-work: I forgot to add a line for service coil to go out and perform a dummy whipstock drift and mill out the XN nipple at 10,131' MD. Please see the atttached word document to see the change. Post-work: The completion strategy on this one is a bit different compared to our normal completions. The plan is to bring cement top to just outside the window. This will be done on calculations only based on drilling conditions(i.e. losses, size/condition of hole drilled). There is the potential of running a CBL with the CNL logging package to confirm top of cement. There is a contingency for running a slotted liner completion which would eliminate the cement job altogether and still allow for production from both laterals. The other interesting note that we discussed is the possiblity of perforating the existing CTD liner for additional area open to flow if it is found that the original lateral (14-11A) is not sufficiently contributing to production. To confirm what we discussed in writing about the 4-1/2" mono-bore whipstock, it is flow-through and will not be squeezed off with cement therefore allowing the original well (14-11A)to produce. «14-11AL1 PTD Application —sent to AOGCC.doc» Regards, Operations Drilling Engineer Coiled Tubing Drilling BP (Exploration)Alaska, Inc.
