History and current status: 02-18 was originally drilled in 1980 as an Ivishak producer. It has been CTD sidetracked twice with the last CTD sidetrack occurring in 2007. A hole in the tubing was discovered in 2009. A patch was successfully set and the well produced until 2010 when 2 additional leaks were discovered. 02-18B is an inoperable well and is not economic to fix the well for the remaining reserves of the current sidetrack. The proposed sidetrack will access -40 acres in the northern area of DS 02. Proposed plan: Sidetrack 02-18B to the 02-18C location using Nordic 1 Coiled Tubing Drilling rig on or around February 1St, 2014. The 02-18C sidetrack will exit the existing 3-3/16" liner and kick off in Zone 2 and land in Zone 1. This sidetrack will be completed with a 2-3/8" L-80 liner and cemented in place. This Sundry covers plugging the existing 02-18B perforations via the 02-18C primary liner cement lob and a liner top packer if the liner lap pressure 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. cviscw. wei, prod .es q 70000-1- 604 14.c4 2o ova scrip?, 11)4c0" T +.r I c /awe 4..e�4 E-' _ 01:-;/ 7�it f in co jet i�f c 4� l e n2 -ofri//ed 1b Cc / �°c.- ,.� C- �OriJ P CRif o fecOrer> 4-o 4/5 por '04 t%s��j Pre-Rig Work(scheduled to begin November 1St, 2013) 1.

However, some of the activities may not be specifically related to the 10-403 plugging request. So, for those steps associated with the permanent plugging of the existing completion or for those steps which are permanent changes to the wellbore (cannot be reversed-- for example, non-retrievable whipstocks), 10-403 approval is required before proceeding. These steps are noted by "Yes" in the 10-403 column. Required Permit? Pre-Rig Work(scheduled to begin November 1St,2013) 10-403 PTD 1. S Pull ball, rod, and RHC plug body. No No 2. S Drift for WS.

When a Form 10-403 is submitted requesting approval to plug a well for redrill,the initial reviewer(Art or Steve D.)will check to make sure that the "Plug for Redrill" box in the upper left corner of the 403 form is checked. If the "Abandon" box is checked,we will cross that erroneous entry out and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2. On the Form 10-403 if"Abandon" is checked in Box 15 (Well Status after proposed work), Art or Steve J D. will cross that erroneous entry out and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). Instead, we will check the "Suspended" box. Guy and Winton will serve as quality control for steps 1 and 2. 3. When Steve McMains receives the Form 10-403 with a check in the "Plug for Redrill box, he will enter the existing code "IBPRD" into RBDMS. This code automatically generates a comment under the History tab stating "Intent: Plug for Redrill." 4, When Steve McMains receives any Form 10-407, he will check the History tab in RBDMS for this comment. If he sees the "Intent: Plug for Redrill" code, and cannot find any evidence that a subsequent re-drill has been COMPLETED, he will assign a status of SUSPENDED to the well bore in RBDMS, no matter what status is listed on the 10-407. Steve will also change the status on the 10-407 form to SUSPENDED, and will date and initial his change. If Steve does not see the"Intent: Plug for Redrill" comment or code, he will enter the status listed on the Form 10-407 into RBDMS. 5. When the Form 10-407 for the redrill is received, Steve M. will change the original well's status from suspended to abandoned. 6. The first week of every January and July, Steve M. and Steve D. will check the "Well by Type Work Outstanding" user query in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, Steve M. and Steve D. 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 • • BP Exploration (Alaska) Inc.

(2) All depths are Bit Depths unless otherwise noted. (3) All True Vertical Depths (SSTVD) are SubSea corrected. (4) All Formation Evaluation data is realtime data. (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 Circulatinq Sub, a Drilling Performance Sub (Inner and Outer pownhole Pressure, Vibration and Downhole Weight on Bit), a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor and Ultra Slim Resistivity Sub. (7) Data presented here is final and has been depth adjusted to PDCL (Primary Depth Control Log from Schlumberger MCNL dated 8-Jun-2007. (8) The sidetrack was drilled £rom 02-18 through a milled window in 4.5" liner.

(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 pownhole Pressure, Vibration and Downhole Weight on Bit), a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor and Ultra Slim Resistivity Sub. (7) Data presented here is final and has been depth adjusted to PDCL (Primary Depth Control Log from Schlumberger MCNL dated 8-Jun-2007 per Douglas Dortch with BP Exploration (Alaska), Inc.
