Request: Approval is requested for the P&A of Prudhoe Bay well Z -10 to sidetrack and complete Z -10A. Reason for Sidetrack: Produce Ivishak reservoir Zone 4, 46 -42P. Well History: Z -10 is an Ivishak producer with original completion in 1989. The well was frac'd in June 1990, targeting Zone 42P and 43P (the well screened out early). Had acid stimulations 1990, 1995, 1998, and 2010 to increase production. The original 3 -1/2" Tubing was replaced with 4 -1/2" 13Cr Tubing by RWO in 1991. Ad -perfs were shot in 1994, 2004, 2008, and 2009. This well became a sidetrack candidate in 1999 due to liner problems. Currently the well is low PI, low oil rate and not competitive. No viable wellwork options remain. Well has been shut in since 09/2010 (was online for 2 weeks in 2011). Cemented 13 -3/8" surface casing (17 -1/2" hole size) with 783 bbls of Permaforst cement to surface. No LOT recorded. Cemented 9 -5/8" casing (12 -1/4" hole size) with 512 bbls Class G cement. No problems with cement job reported. With 30% washout, cement top calculated to be at 6031' MD. No LOT recorded. Cemented 5 -1/2" liner with 101 bbls of 16.0 ppg Class G cement to liner top. No problems with cement job reported. CBL log run on 5 -1/2" liner shows fair to good cement throughout liner. Scope of Work: The sidetrack plan for the Z -10 well includes the following: pre -rig operations will include laying cement across the perforations, circulating a 1200' MD cement plug into the IA and tubing above the production packer by means of a GLM and cutting the 4 -1/2" tubing at approximately 9800'. Pull tubing, and run a clean out run. A whipstock will be set to exit the 9 -5/8" casing at —9600' MD.

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 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.

Commissio Anchorage BP Exploration / ARCO Alaska Inc. To: From: Subject: Reference: Blair Wondzell - AOGCC Date: December 7, 2000 Troy Miller Z-10 Application for Sundry Permit - P&A for Sidetrack Operations APl #50-029-21986-00 Sundry approval is requested for the proposed DS Z-10 perforation P&A. The well is currently shut-in due to high WC production, resulting from a severely corroded liner and frac into bottom water. The poor mechanical condition of the liner limits cost effective wellwork or workover options, and therefore a sidetrack was proposed. The sidetrack will replace the current wellbore with an extended horizontal wellbore approximately 2700 feet from the original well, to recover the remaining Z-10 and surrounding area reserves. The sidetrack is currently scheduled for Nabors 7ES beginning around January 10, 2001. The pre-rig work for this sidetrack is planned to begin as soon as the attached Application for Sundry is approved. Below is an outline of the proposed P&A and sidetraCk operations. Pre-Rig Work: * Notify the field AOGCC representative with intent to plug and abandon * 1. RIH with CTU to top of fill at _13,608' MD (tagged 12/8/96). Perform a cement P&A using 15.8 ppg class 'G' cement with adequate cement volume to fill the 5-1/2" liner from top of fill to a minimum of 100' above top perforation, plus squeeze 5 bbls to the perforations. Estimated minimum cement volume needed is 10 barrels. NOTE: 10 bbl of cement will leave top of cement higher than 13,414' MD (after 5 bbl squeeze) for AOGCC compliance. Actual TOC may be left up into tubing tail. Use aggregate as required to aid in plugging the perfs. Circulate well clean above cement plug. 2. Rig up slickline, tag and document top of cement and drift tubing for upcoming tubing cut. 3. Liquid pack the 9-5/8" x 4-1/2" annulus to surface. Test the integrity of the cement plug and 9-5/8" casing by simultaneously pressure testing both the tubing and 9-5/8" annulus to 3000 psi for 30 minutes. Increase tubing pressure prior to the 9-5/8" annulus to avoid possibility of tubing collapse. NOTE: This step should be completed prior to the tubing cut to allow additional troubleshooting if either the cement plug or the 9-5/8" casing is leaking. 4. Cut the 4-Y2" 12.60# 13Cr-80 tubing at 12,700' MD or as deeply as possible (as per the 11/25/91 Tubing Summary, 12,700' is -14' down into joint #1). NOTE: The type of cutter to be used is at the discretion of the Wells group. This cut will not be fished; however, avoid cutting tubing at a coupling. 5. Displace the well to clean seawater by circulating down tubing through the tubing cut. Continue to circulate until clean seawater returns to surface. Freeze protect top 2200' MD with diesel. The well should not be left with methanol as a freeze protect fluid, diesel only. 6. Test the FMC 9-5/8" mandrel packoff and tubing hanger seals to 5000 psi for 30 minutes. Bleed tubing and annuli pressures to zero. Set a BPV in the tubing hanger and test from below to 1000 psi. Secure well. . Remove the well house and flowlines. If necessary, level the pad. Please provide total well preparation cost on the handover form. Rig Operations: . MIRU Nabors 7ES. Circulate out freeze protection and displace well to seawater. Set TWC. Nipple down tree. Nipple up and test BOPE. Pull and lay down 4-1/2" tubing from E-line cut and above. MU 9-5/8" window milling assembly and RIH to top of 4-1/2" tubing stub. POOH.

The BOP test went very well and no failures were noted. Nabor's Rig 2-ES consistantly runs a good BOP test and welcomes the inspector's visits. Ail components were functioned and tested to 5000 psi with the exception of the annular BOP which was tested to 2500 psi. All phases of the test were performed properly and held the pressure applied. Although the rig had just moved to Z Pad from S Pad, the rig crew had the location in order with no trash in sight. In summary, Nabor's Rig 2-ES is a good looking rig and appears to be in good shape for working over BPX Well Z-10. Attachment 02-00lA (Rev. 6/89) 20/11/MEMO1.PM3 OPERATION: Operator Drl g Wkvr ?
