History of B -27A. Well B -27A was drilled as a rotary ST completed in June 1996 in the 23P sand. The well came online but quickly struggled. In July 1996, 60' of adperfs were shot in the 22P sand. The well flowed for about 9 mos until the oil rate declined, and then adperfs were shot in the 24P.15' in the 25P were shot in Nov 1997. The well produced fulltime with declining production for several years. The 23P perfs were re -shot in April 2000, and the production slightly increased for —6 mos before starting to decline. In 2006 it was shut -in for TxIA comm and remained offline until a RWO restored integrity in Aug 2008. In mid 2011 B -27A was shut -in for high GOR. After reviewing the STPs from 1999- 2009 and offset production, an increase in gas production from the 25P was identified and that the 23P pert interval may have scale. During the GSO wellwork job in Dec 2011, a tractor with a CIBP got stuck in the liner at —11000' in scale. B -27A is currently shut -in for high GOR. Reason for sidetrack. B -27A is no longer a competitive well due to high GOR. The proposed sidetrack will access a target in Zone 2A & 2B. Proposed plan for B -27B is to drill a through tubing sidetrack with a Coiled Tubing Drilling rig on or around October 15 2012. The existing perforations will be isolated by a 4 -1/2" packer whipstock. The sidetrack, B -27B, will exit the existing 4 -1/2" liner and kick off in Zone 4 and land in Zone 2B & 2A. This sidetrack will be completed with a 3 -1/4" 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. We /i u 'r4 6o' 0 y s Y' 114 :/< Co n Q Q `AP Art.

Benson Blvd.1Room: 788D 'Anchorage, AK 9/21/2012 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 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.

Supervisor o\ Jeff Jones, Petroleum Inspector January 18, 2001 Safety Valve Tests Prudhoe Bay Unit B Pad ThurSday, January 18, 2001' I traveled to BPXs B Pad and witnessed the semi annual safety valve system testing. As the attached AOGCC Safety Valve System Test Report shows I witnessed the testing of 17 wells and 34 components with 2 failures. The Pilot on well B-18 tripped below the required set point and the pilot on well B-21 was frozen. Both failures were repaired and sUcessfuily retested before I departed location. The new style pil°t insulation box fabricated using pipeline insulation installed on most wells on this pad should be installed on the remaining SVS pilots to eliminate the freeze u'p Problems evident on this pad. I also inspected the well hOuses on this pad while witnessing SVS testing. All the well houses inspeCted were clean and the equipment appeared to be in good condition. : Summary: I witnessed the SVS testing at BPXs PBU B Pad PBU B Pad, 17 wells 34 components 2 failures 5,8% failure rate 22 well house inspections ~ Attachment: SVS PBU B Pad 1-18-01 JJ X Unclassified Confidential Confidential (Unclassified if doc. removed ) SVS pBu B Pad 1-18-01 JJ.doc Alaska Oil and Gas Conservation Commission Safety Valve System Test Report Operator: BPX Operator Rep: Merv Liddelow AOGCC Rep: Jeff Jones Submitted By: Jeff Jones Field/Unit/Pad: PBF /PBU /B Pad, Separator psi: LPS 174 Date: 1/18/01 HPS 658 Well Permit Separ Set L/P Test Test Test Date Oil, WAG, GINJ, Number Number PSI PSI Tdp Code Code Code Passed GAS or CYCLE B.01 1700080 174 125 120 p P OIL B-02A 1961110 658/174 550/125 500/120 p P OIL B-03B 1870480 B-04 1700320 B-05A 1960990 B-06 1770740 174 125 120 P P OIL B-07 1780020 658 550 520 'P P OIL B-08 1780410 658/174 550/125 510/110 p P OIL B-09 1780490 B-10 1780540 174 125~ 110 P P OIL B-11 1780690 B-12A 1970090 658 550 530 p P OIL B-13A 1990570 B-14 1780930 B-15 1790190 B-16 1790250 ~B-17 1790280 B-18 1820020 658 5501 01 3 P 1/18/01 OIL B-19 1820030 174 125 120 p P OIL B-20 1821680 174 125 120 p P OIL B-21 1821760 658 550 510 2 P 1/18/01 OIL B-22 1820890 B-23A 1970590 658/174 550/125 550/120 p P OIL B-24 1821400 !B-25 1821510 174 125 115i p P OIL ~B-26B 2000570 '174 125 125 p P OIL B-27A 1961010 658/174 550/125 520/125 p p OIL B-28 1853030 · B-29 1860140 B-30 1860310 B-31 1910460 B-32A 1991180 B-33A 1931450 174 125 115 p p OIL B-34 1930370 Pad 1-18-01 JJ.xls Well Permit Separ Set L/P Test Test Test Date Oil, WAG, GIN J, Number Number PSI PSI Trip Code Code Code Passed (;AS or CVCL~ B-35 1931460 B-36 1960650658/174 550/125 540/120 p p OIL J-05B 2000180 - I Wells: 17 comPonentS: 34 Failures: 2 Failure Rate: 5.8% Remarks: The 2 failures were corrected and paSsed a retest. ~/~o/a~ pa~e 2 of 2 SVS PBU B Pad 1-18-01 JJ.xls ON OR BeFORE ¢:LO~tixtvl~M-~C PERMIT DATA 96-101 7304 96-101 SSVD AOGCC Individual Well Geological Materials Inventory Page: 1 Date: 06/09/98 T DATA PLUS RUN RECVD ClDLLIMLL/CN/GR 10115-11402 1 ~L~EPIA 11404-9978 1 06/28/96 06/28/96 96-101 BHP ~I/S EP IA 11404 -10110 1 06/28/96 96-101 CN/GR ~5/'SEPIA 11404 -9978 1 06/28/96 96-101 DLL/MLL/GR 96-101 SONIC ~I~SEPIA 11404-9978 ~-~SEP IA 11404 -9978 1 06~28/96 1 06/28/96 96-101 GR/CCL 96-101 NGP-MD L 11530-11346 ~i0118-11415 1 08/02/96 FINAL 01/08/97 96-101 NGP-TVD 96-101 CNTD ~"~8488-9069 ~L~10050-11331 FINAL 01/08/97 FINAL 02/21/97 96-101 7617 96-101 7915 .~--SCHLI/M CNTD ~PERRY GR 1 02121/97 2-6 03~05/97 96-101 PERF 96-101 PERF 96-101 PERF FINAL 06/06/97 FINAL 06119197 FINAL 11/10/97 ~10900-11200 L 10800-11150 ~0745-11030 L.R~OMPLETION DATE 10-407 --~//~. 3/ f6/ DAILY WELL OPS R ~/30 Iq~l TO 5~/.~ $,~/~ / '-?/2~ /~/{~/ Are dry ditch samples required? yes ~ And received? yes ~ Was the well cored? yes n~Analysis & description received? -yes no Are well tests required? ,,,yes ~!~ Received? yes~. // Well is in compliance ~j I~itial COMMENTS STATE OF ALASKA - ALASKA ( AND GAS CONSERVATION COM. .SSlON REPORT OF SUNDRY WELL OPERATIONS 1.
