History of 06-02. 06-02A is a CST completed in May 2011 with 500' of perfs in Zone 2A in the GDWFI area. The well was originally designed to have a lateral in Zone 2A and then toe up to a Zone 2B target. After having wellbore stability issues with the toe-up through the 22N shale, the well was openhole sidetracked and completed in only Zone 2A below the 22N shale. Initial production was lower than expected. Historically, wells drilled in this area clean-up in 3-4 months and draw in enough oil to flow competitive. However, this well did not show any improvement over several months. In April 2012, a plug was set over the existing open Zone 2A perfs and 10' of Zone 2B in the heel of the well were shot. Unfortunately, these perfs were too close to the parent well and were gassed out. 06-02A remains shut-in due to high GOR. Reason for sidetrack. 06-02A is not a competitive producer due to a high GOR, and there are no remaining wellwork options. The proposed sidetrack will access reserves in a —55 acre GDWFI target (Zone 2B1) in northwestern DS 06. Proposed plan for 06-02B is to drill a through tubing sidetrack with the SLB/Nordic 1 Coiled Tubing Drilling rig on or around November 15th, 2012. The existing perforations will be isolated by the primary cement job for the liner. The sidetrack, 06-02B, will exit the existing 3-3/16" liner, kick off in Z2, and land in Z2B. This sidetrack will be completed with a 2-3/8" liner in the production interval. The following describes the work planned and is submitted as an attachment to Form 10- 403. A schematic diagram of the proposed sidetrack is attached for reference. (o icer .

Page 1 of 1 Subject: FW: INTENT PLUG for RE-DRILL WELLS: Corrected From: Davies, Stephen F (DOA) Sent: Monday, February 08, 2010 10:52 AM To: Foerster, Catherine P (DOA); McMains, Stephen E (DOA); Schwartz, Guy L (DOA); Saltmarsh, Arthur C (DOA); Aubert, Winton G (DOA) Subject: RE: INTENT PLUG for RE-DRILL WELLS: Corrected Revised procedure with an additional step per Cathy's comment: INTENT PLUG for RE-DRILL WELLS (IPBRD)Type Work Code in RBDMS 1. 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 1/ 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.
