Johnston b p CTD Engineer Date: April 10, 2013 Re: E -01A Sundry Approval Sundry approval is requested to plug the E -01A perforations as part of the drilling and completion of proposed E -01B coiled tubing sidetrack. History and current status: Original E -01 Tubulars are from 1976. Well was TTRD sidetracked to E -01A in 2003. The well came on with acceptable GOR, but only very slowly increased in GOR until it was SI in early 2010 for finally reaching MGOR. The well has been cycling with degrading performance since. A CIBP was , set isolating the bottom most set of perfs in mid -2011, but minimal effect was seen on overall production trends. There are no further wellwork options on this well, and is a strong candidate for • CTD sidetrack. Proposed plan: Sidetrack E -01A to the E -01B location using Nordic 1 Coiled Tubing Drilling rig on or around May 1, 2013. The E -01B sidetrack is planned to exit the existing 3.3/16" liner and kick off in Zone 2 and land in Zone 2. This sidetrack will be completed with a 2 -3/8" L -80 liner and cemented in place. This Sundry covers plugging the existing E -01 A perforations via the E -01 B primary liner cement job and a 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. Required Permit?

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.

The sidetrack, E-01 A, will exit the 7" liner in the Ivishak Z4 and will come down through the conglomerate of Z3 to a Z2B target. Phase 1, Well preparation: After verifying tubing & casing, wellhead and tree valve integrity a thru-tubing 4Y2" x 7" whipstock will b~. n... on e-line and set with a highs ide orientation at 9415'. Following the whipstock set, 0 Is of cement will be pumped and squeezed with 1 %" service coil to P&A the open . órations below the whipstock. Phase 2, CTD Operations: Nordic 1 CTD rig will MIRU with 2%" coil. After milling a window in the 7" liner off of the whipstock @ 9415', -1250' of 3%" open hole will be drilled. From Z4, drilling will be through the conglomerate of Z3 and into a Z2B reservoir target. Solid 2Ÿ8" x 3-3/16" liner will complete the sidetrack. This will be cemented ,'place and selectively perforated. One objective will be to place the cement top at 9,300', -100' above the window. This is to preserve future sidetrack opportunities, following a cut and pull of the sidetrack liner. Nordic 1 will most likely move onto E-01 during the first week of April 03. /" Mud Program: Plan to mill the window in the 7" liner with an 8.6ppg 2% KCI / Y2ppb biozan fluid system. Thereafter an 8.6ppg Flo-Pro mud system will continue to be used to drill the formation. Disposal: /' · All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. ,. · All Class I wastes will go to Pad 3 for disposal. Casing Program: The production liner will be solid 2}Í¡" x 3-3/16" L80, run from TD, 10,665'md, (8995'tvdss) to 9,004'md (-8494'tvdss). It will be cemented back to 9,300' with approx 12Y2bbls of Class G Latéx cement. The plan is to bring the cement top - 100' above the window to preserve future sidetrack opportunities. If the cement fails to hydraulically isolate the sidetrack a liner top packer will be run to complete the job. Well Control: · BOP diagram is attached. " · Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 3500 psi. / · The annular preventer will be tested to 400 psi and 2500 psi. Directional · See attached directional plan, (E-01A Plan #5. Max. planned hole angle is 90°) · Magnetic and inclination surveys will be taken with MWD every 30 ft. Logging Real time MWD & Gamma Ray logs will be run over all of the open-hole section. A memory CNL log will be run in the cased hole. Hazards · H2S on E-01 has not been measured. Max recorded H2S on E-Pad is 1 Oppm from well E-08 · There is one 10' throw fault, which will be crossed perpendicularly. There is a moderate chance of lost circulation although the parent well crossed the same fault without incident. Reservoir Pressure Res. press. is estimated to be 3300 psi at -8800'ss (7.2 ppg emw). Max. surface pressure with gas (0.12 psi/ft) to surface is 2244 psi. / TREE = WELLHEAD = ActuÄtoR; Kä:Els/" ;;...... .......,........... ..........."". BF.

SPACING EXCEPTION DRY DITCH SAMPLE Rev: 07/10/02 C\j ody\templates The permit is approved subject to full compliance with 20 AAC 25.055. Approval to perforate and produce is contingent upon issuance of a conservation order approving a spacing exception. (Company Name) assumes the liability of any protest to the spacing exception that may occur. All dry ditch sample sets submitted to the Commission must be in no greater than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones.
