History and current status: Parent well, C-08B, was completed in 2005 as a lateral extension out of the toe of C-08A. A slotted liner was run in Zone 1A/1 B. The initial oil rate was high but quickly dropped with increasing gas within a few months. In 2006 a plug was run to shut in the new slotted liner, returning production to the cycling parent well perfs in C-08A. The plug was pulled in April 2013 to test the toe which brought in an uncompetitive level of gas. In January 2015 a gas log showed no add perf potential and the plug was reset unsuccessfully. It was reset in March 2015 back to Zone 1A perfs of C-08A which are no longer competitive after ten additional years of cycling. The well has no remaining value and has been released for sidetrack. Proposed plan: Approval is requested to drill a CTD sidetrack lateral from well C-08B by the Nordic 1 Coiled Tubing Drilling rig on or around November 15, 2015. The C-08C sidetrack will perform a single-string exit through the existing 4-1/2" liner. Kick-off will occur in Zone 1A and target Zone 1A/1 B reserves. The proposed sidetrack is a —2,410' horizontal Ivishak Zone 1A/1 B producer which will access targets north of C-Pad. The lateral will be completed with a 3-1/2" x 3-1/4" x 2-7/8" L-80 liner which will be cemented and perforated. This Sundry covers plugging the existing C-08B perforations via the C-08C liner cement job or liner top packer (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. w / " C / ffTc S it'e� x/ -e pock he o e� l �D �Q�� . w�r� f to rtrr� I,' t� ©� ra Te ®� / /^ Qs�a 70 ,1 cis;_. �.���t��n aPQ�i°r GDR r � l P rlv i 74,c for fedr`(l "kW, a//c ✓ l '')"'"C" Pre-Rig Work(scheduled to begin September 15, 2015) 1.

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.

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.

There is a discrepancy for the conductor and surface casing descriptions between what is listed on the 407 and the wellbore diagram. Could you check this.

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 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). ITEM 20: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 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). ITEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None".

Directional · See attached directional plan. Max. planned hole angle is 99deg. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. · Distance to nearest property - 19500 ft. · Distance to nearest well within pool -800 ft. Logging · MWD directional and Gamma Ray will be run over all of the open hole section. Hazards / · C pad is I.!QLdesignated as an HzS pad. No H2S recorded events on C-08. The maximum recorded H2S level on pad is 10 ppm (C-26 & C-27) · Drilling out of an abnormally low pressured zone- Risk of lost circulation and differential sticking. Use PIo-Pro drilling mud to minimize the risk. Reservoir Pressure · Res. press. is estimated to be 3250 psi at 8800'ss (7.1 ppg EMW).
