History and current status: W -18 was completed in 1988. It is a high water -cut well. Serious water breakthrough seems to have occurred in 2008 -2009. This well is no longer economic and there are no • remaining well work options. Proposed plan: Sidetrack W -18 to the W -18A location using Nordic 2 Coiled Tubing Drilling rig on or around September 1st, 2013. The W -18A sidetrack will exit the existing 7" liner and kick off in the Shublik formation and land in Zone 4. This sidetrack will be completed with a 2 -3/8" 13Cr liner and cemented in place. This Sundry covers plugging the existing W -18 perforations via the W -18A 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. `prods ce o � 12 p '4/' iafif T'i i k.e, // S C 04 cv/. u✓4 / � a f/ lt0 o % ea/ ro le fS -Mali /SO BD /� ' set k ,, 'f4 q t4.1 ih P ")- (91e- 93-% .

When a Form 10 -403 is submitted requesting approval to plug a well for redrill, the initial reviewer (Art j 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.

BOP Test SAPC PBU W- 18 Permit No. 88-128 Prudhoe Oil Pool FROM: Harold R Hawkins Petroleum Inspector~ ~ Tuesday, November 15, 1988: I left Anchorage at 7:15 a.m. by Alaska ~ir'%ine~,~"arriving at prudhoe Bay at 8:45 a.m. I arrived at SAPC PBU W-18 (41-21-11-12) at 9:15 a.m. to witness a BOP test. When I arrived on location the BOP stack was almost nippled up to test. Then problems started. The speed head was loosened when an attempt was made to connect the choke line to the BOP stack. The stack had to be nippled down to pick stack up from speed head so as to tighten speed head up. Testing of BOP started at 6:00 p.m. Three failures right at the start stopped the testing. The right ram shaft packing failed, and two new valves on the speed head failed. Wednesday, November 16, 1988: I consulted with the SAPC operator, Don WeSter,"and"the Nab°r~-~2E tool pusher on how to retrieve the ram shaft and pack. assembly from the BOP housing, as they requested my expertise. At 4:00 a,m. testing resumed. There were four more failures. The top drive BOP (kelly) failed; a choke valve on the manifold failed; and the secondary pump on the accumulator failed. One bank of four accumulator bottles was out of service. Time finished, 8:00 a.m. In summary, as far as procedures and testing was concerned, it was satisfactory on Nabors 22E~ but I am quite concerned, because of the time it took and problems with this test, whether the BOP tests are being performed completely when an inspector is not present. SAPC is to call AOGCC when failures are repaired. -~ ,: Attachment Saturday, November 19~ 1988: Don Wester, operator for SAPC, called me-'"a~'d' Said 'all' fail~'u~eS were repaired and tested. 02-00~"A (Rev. 8~85) .

The permit to drill does not indemnify you from the probable need to obtain additional permits required by law from other governmental agencies prior to commencing operations at the well site. To aid us in scheduling field work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. Where a diverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe. ~ tr~ly~Du~s, ." ,/ -~/ ,'. ./ .... , : C.
