The lateral was drilled in good quality Zn 1B sand and the liner was successfully run to TD. Unfortunately, the cement job failed. The liner wiper plug stuck in the liner at—10540', leaving cement inside the liner and preventing liner access past that point. Without access to the liner, it could not be logged or perforated. In hopes of re-sidetracking to the Zn 1B target, two liner cut&pulls were attempted (cuts at 10205' and 10435') but the liner could not be pulled out of hole. The rig left location on 4/26/11. The well never perforated or produced. Reason for P&A/RST: As the 02-12C well was a failed CST, the well needs to be P&A'ed in preparation for the planned 02-12D RST. The proposed sidetrack is a 2,000' horizontal Ivishak Zone 1 B/2A producer, , which will replace the 02-12C CST and access additional Zone 16/2A reserves in southeastern DS 02. The parent well (02-12C) is a failed CST without access to the liner and can no longer be coil sidetracked. The proposed sidetrack will provide offtake in —50 acre drainage area in western DS 02 and restore wellbore integrity. Other Requests: None. Scope Planned Sundry Work: As currently planned, the P&A of the 02-12C well and the well work in preparation for the 02-15D rotary sidetrack will be as follows: 1. As pre-rig work; a. place a —500' cement plug on both sides of the tubing from —9638' MD (est. TOC at 9138' MD). b. make a tubing cut at 8800' MD. 2. With the drilling rig on the well; a. pull the 4-1/2"tubing from 8800' MD. b. Clean-out the well to the top of the tubing stub at 8800' MD. c. Set an EZSV at—8496' MD and test. d. Run 9-5/8"whipstock and set on the EZSV at—8496' MD. e. Change-out tubing spool and 9-5/8" pack-off. MASP: 3235 psi @ 8211' TVDss (9.5 ppg pore pressure at TPTR) Estimated Pre-Rig Start Date: 08/15/12 02-12C Sundry Application 1 7/24/2012 Proposed Pre-rig prep work: 1. MIT-T to 3000 psi. MIT-IA to 3500 psi. MIT-OA to 2000 psi. 2. Perform a tubing punch just above the existing production packer at 9599' MD (tubing punch at —9540' MD)to allow fluid circulation to the IA at that depth and circulate the well to clean seawater on both sides of the tubing. 3. Place 500' cement plug from the top of the bridge plug at 9638' MD (on both sides of the tubing above the production packer at 9599'' MD). (-35 bbls of 15.8 ppg G cement. Est TOC at 9138' MD.) 4. PT cement to 2500 psi. tr.�iu-r-��30•�•.-••. 5. D&T cement/drift for jet cut on tubin . 6. Jet cut the 5-1/2"tubing at 8800' MD and freeze protect both sides of the tubing with diesel to 2000' MD. 7. CMIT-TXIA to 3500 psi. 8. PPPOT-T and IC. Function LDS. 9. Set BPV and test. Planned Rig Work: 1. MI/RU/confirm barriers. atiti.273 2. Nipple down tree. Nipple up BOPE and test to 250 psi low/3500 psi high. 3. RU and pull the 5-1/2", 17#tubing from the pre-rig jet cut at—8800' MD. 4. PU 8-1/2" clean-out assembly and RIH to clean-out 9-5/8"casing to top tubing stub at—8800' MD. 5. RU E-line and RIH w USIT / CCL / GR to 9000' and log to surface to determine TOC behind the 9-5/8" casing in the 12-1/4" open-hole (if any) and in the 13-3/8"x 9-5/8" OA(est. TOC —2250' MD). 6. RU E-line, RIH with GR/CCL and 9-5/8" EZSV for 47# casing. Set the EZSV at —8496' MD (competent sand / confirm with GR) as required to avoid cutting a casing collar while milling the window. POOH. Rig down E-line. 7. Pressure test the EZSV to 3500 psi for 30 minutes and chart. 8. PU and RIH with 9-5/8" Baker bottom-trip anchor whipstock assembly and 8.5" window milling assembly (to include full gauge string mills). RIH to the top of the EZSV. Orient and set the whipstock. Shear off the whipstock. 9. Hang the milling BHA on a storm packer and change-out the tubing spool and the 9-5/8" pack-off.

I am not able to determine the quality of the cement due to the very high possibility that a microanulus is present and affecting the CBL response. From the VDL measurement it is evident that there is cement in place between the Sag and Put River and above to at least 8980'.Any attempt to further improve the quality of cement through additional squeezes would most likely be impossible. Let me know if you have any questions.

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 / 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.

Anyhow I will give you a description of what happened and if you need more detail please feel free to give me a call. We ran the liner and everything went as planned. During our cement job, we saw high pressures (-4,000 psi) during the entire cement job. We saw a pressure spike which indicated we had bumped the plug. We LD the cement BHA and RIH with our cleanout assembly. We tagged hard and milled at 10,540' MD. It was then determined the liner wiper plug had been caught in a pup joint(this after much research in looking in tallies and barrels displaced). We ran a SCMT which came back showing there was cement behind pipe but after getting Schlumberger to look at it, it was determined to be a false reading. We RIH and tried to pull out the liner but failed. We then went back in with a jet cut and made a cut at 10,435' MD and tried to pull out the above liner in hopes of setting another whipstock and drill a new lateral. This also failed so we went back in one last time and made another jet cut at 10,205' MD and tried pulling the liner. This was also unsuccesful. We then POOH and RDMO to next well, leaving this well suspended. If you need more information please give me a call.

Well 02-12B was drilled in July 2007 as a CTD sidetrack targeting Z1B/2A in southern region of DS2. The well was completed with 250' of Z1B and 485' of Z2A perforations. The 3-3/16" liner lap failed the initial pressure test to 2050 psi (lost 200 psi in 10 min) and a liner top packer was installed. After installing the liner top packer, the liner lap passed a pressure test to 2030 psi. The well is currently shut in for high GOR. In August 2007, borax CNL and STP logs were run to identify the gas source and evaluate potential gas shut-off options. The borax log indicated no channels behind pipe. The STP log showed equal flow contributions from the 2 perforation / intervals but a cooling anomaly was detected on the flowing and residual temperature passes at 11,320' in the Z2A perforations indicating a likely source of gas entry. The GOC was predicted in mid-Z2A but many of the offset wells have coned GOC picks. It is likely that 02- 12B is experiencing a comparable coning affect. In July 2008, a CIBP was set at 11,175' to shut-off the Z2A perforations at the toe of the well. There '/ are still open perforations from 10,830' to 11,080'. In August, 2010, a caliper was run from 10,460' to surface. All tubulars were in good shape. However, it did show slight corkscrew throughout the 3-3/16" liner. The MIT-IA passed to 3,000 i psi and MIT-OA passed to 2,000 psi. The proposed plan for 02-12C is to drill a through tubing sidetrack with the SLB/Nordic 2 Coiled Tubing Drilling rig on or around March 26, 2011. The existing perforations will be isolated by setting the 3-3/16"packer whipstock, as well as the primary cement job. The sidetrack, 02-12C, will exit the existing 3-3/16" liner and kick off in Ivishak,tagging HOT in Z1B and drilling 2,075' of lateral. The completion will be 2-3/8" Carbon Liner. 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.

(3) All True vertical Depths (TVDSS) 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 109 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 has been depth shifted to a Primary Depth Control (PDC) log provided by Schlumberger GR CNL dated 21 Jun 2007 above the Kick off Point of 10132 feet MD per Walter Tifental with BP Exploration (Alaska) , Inc. The MWD data is now the PDCL for well 02-12C. (8) The sidetrack was drilled from 02-12B through a milled window in a 3 1/2 inch liner. Top of window 10132 ft.MD (8750.4 ft.TVDSS) Bottom of window 10136 ft.MD (8753.7 ft.TVD55) (9) Tied to 02-12B at 10119 feet MD (8740.1 feet TVDSS) . (10) Baker Hughes INTEQ run 5 was used to set a bridge packer above SSSV. No logging data is presented. (11) Baker Hughes INTEQ run 6 was unable to reach bottom and pulled out of the hole due to potential motor chunking. No logging data acquired. (12) The interval from 12575 ft to 12598 ft MD (8977.5 ft. to 8977.3 ft. TVDSS) was not logged due to sensor to bit offset at well TD.
