From: David Minge bp CTD Engineer 1# 0.0 Date: August 28th, 2015 Re: 15-07C, 15-07CL1 Sundry Approval Sundry approval is requested to plug the 15-07C and 15-07CL1 perforations and slotted liner as part of the drilling and completion of proposed 15-07D coiled tubing sidetrack. History and current status: 15-07C is a Zone 1 producer that was drilled in 2003. The 15-07CL1 zone 1 lateral was added in 2010. The well is still producing but with a rapidly increasing GOR, and it is not expected to remain competitive. There are no remaining well work options to enhance production. Proposed plan: 15-07D will be drilled from well 15-07C by the Nordic 2 Coiled Tubing Drilling rig on or around September 25th, 2015. The 15-07D sidetrack will exit through the existing 4-1/2" liner and kick off in the Ivishak, and target Zone 1 reserves. The proposed sidetrack is a —3,000' horizontal Ivishak Zone 1 producer, which will access a -35 acre reserves target off of DS15. The lateral will be completed with a 3- 1/2" X 3-1/4" X 2-7/8" L-80 liner which will be fully cemented and perforated. This Sundry covers plugging the existing 15-07C and CL1 perforations and slotted liner via a CIBP set pre-rig as well as the 15-07D 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.

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. 0 III Image Project Well History File Cover Page XHVZE This page identifies those items that were not scanned during the initial production scanning phase.

This well was sidetracked with the big rig in July 2003 as a Zn 1A horizontal producer with a Zn 1B toe up. Initial production rates were high but dropped 70% in just under a year. At that point it was swapped into the HP system resulting in a small drop in GOR. In an effort to bring in more oil and improve productivity, 75' of Zn 1A perforations were shot in July 2006. The additional perforations brought in an extra 100 -200 BOPD for only a couple of weeks. By November 2007, the well's production was even lower with high GOR and very poor cycle results; therefore a procedure was sent out to set a WRP at 14,620' MD for a Zone 1B toe GSO. However, the well developed a wellhead leak in June 2008 and remained shut -in for almost a year before the wellhead was repaired with a Furmanite wrap in May " 2009. The post Furmanite wrap MIT -OA passed to 1200 psi. The well also passed an MIT -T to 3000 psi in October 2008. The WRP was set with coil at 14,620' MD in June 2009 for a Zone 1B GSO and the well was immediately brought on line in the LP header but was subsequently shut -in for low production on July 17, 2009. Adding a lateral leg to well 15 -07C would add immediate value by increasing the oil rates without abandoning the current reserves and allow it to come online without the aid of gas lift. Recent CTD multilaterals around the GD area have helped to improve production from low rate wells. Well 15 -07C is considered an ideal candidate as there is a good drilling target nearby, the well has low gas rates and the completion allows for the addition of a lateral. The extra leg will allow this wellbore to be put to full utility. The completion will also enable us to isolate either leg by setting a plug or straddle in the future when either leg gasses out. The well, 15 -07C L1, a horizontal leg targeting Ivishak Zone 1A, is scheduled to be drilled by Nordic 2 starting on June 10, 2010. The L1 sidetrack lateral will exit the parent well at 12,735' MD in the Ivishak Zane 1 and drill a -2,220' lateral to a TD of 14,955' MD. The sidetrack will be completed with a 2 -3/8" slotted liner dropped outside the window. The whipstock will be retrieved and production restored from the parent. The following describes work planned. A schematic diagram of the proposed sidetrack is attached for reference. CTD Sidetrack Summary Pre -CT Rig Work: The pre CTD work is slated to begin May 25 2010. 1.

Logging • MWD directional and Gamma Ray logs will be run over all of the open hole section. • • Inner string with MCNL inside liner while deploying liner will be used to log from the liner top to the Top of the Sag River. Hazards • DS 15 is not an H drill site. H levels are typically less than 20 ppm • The maximum recorded H level on Drill Site 15 was 40 ppm on well 15 -20 (07/01/2006). • Overall risk of significant losses during drilling is considered to be low for this well. We are drilling into a fault intersection zone which might indicate a medium risk but we have no mapped fault crossings and no significant losses ( >100 bbls) into Zone 1 have occurred in the area previously which is why we have gone with a rating of low risk for LC. Reservoir Pressure • The reservoir pressure is estimated to be 3,205 psi at 8,681 TVDss (7.1 ppg equivalent). • Max. expected surface pressure with gas (0.10 psi /ft) to surface is 2,337 psi.

(5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to log this well.. (6) Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance sub (Inner and Outer Downhole Pressure, vibration and Downhole weight on Bit), a Directional and Gamma sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor. (7) Data presented here is final and depth ahifting has been waived per Jennifer Flight with BP Exploration (Alaska), Inc. The MWD data is the PDCL for well 15- 07CL1. (8) The sidetrack was drilled from 15 -07C through a milled window in a 4 1/2 liners.
