A tubing caliper was run in 2004 and showed the tuing to be in good condition with only one joint with an excess fo 20% penetration. A LDL in 2005 was run at found a leak at GLM#2. A 20'tubing patch was set in 2006 to restore intecgrity. A well test in 2008 then showed an increased water cut. A sample was taken and showed the possible presence of cretaceous water. An IBP was set at 9263' MD in 2008. The MIT-T passed to 3000 psi. In 2009 a CMIT-TxIA failed with a LLR 5 bpm @2200 psi. A LDL was then run and located the leak in the production ir- casing at 5650'-5700'. Scope of Work: The primary objective of the RWO is to fix the PC leak by running a 5-1/2" scab - liner. Pre Rig Prep Work: W 1 PPPOT-IC to 3500 psi, PPPOT-T to 5000 psi, Check all LDS for movement. S 2 Pull the tubing patch at 6298' MD. Pull the nipple reducer at 8440' MD, pull the 2-1/8" Baker IBP. Set a composite plug at 8515' MD (— mid joint in the first full joint below the LTP See attached 4.5" liner tally dated 6/23/98) F 3 CMIT-TxIA to 3500 psi (to compare leak rate before and after cut) MIT-OA to 1200 psi F 4 Cement control lines E 5 Perform power jet cut at 8409' MD. This depth corresponds to 2' above the bottom collar of the pup joint directly above the packer. The top of the packer according to the 6/24/98 tally is at 8407' MD (see attached tally) F 6 Circulate the wellbore at a max rate with 9.8 ppg brine (total volume of brine should be —430 bbls which is 1.5 of wellbore volume). FP well with diesel to 500'. Perform a post cut CMIT-TxIA to 3500 psi (to compare leak rate before and after the cut) ✓ 7 Set a BPV, ND the tree, NU the dry hole tree, PB IA and upper OA Valves O 8 Remove the well house&flow line. Level the pad as needed for the rig. Proposed RWO Procedure: • MIRU Doyon 14. • ND tree. NU and test BOPE with four preventers configured top down (annular, 3-1/2" x 6", blind shears, mud cross and 2-7/8" x 5"VBR's). Test the blind and VBR's to 3,500 psi and the annular to 3,500-psi. Pull TWC. • Pull the 4-1/2" tubing from the cut at—8409' MD • Mill and Retrieve the old production packer. • Perform a cleanout run and polish the tieback sleeve • Run 5-1/2" scab liner and fully cement with 40 bbls of 15.8 ppg Class G cement. • Change out IC packoff • Test wellbore to 3500 psi. • Drill up shoe trac and composite plug, push to PBTD • Run new 4.5" x 3.5" tubing 13Cr with 5-1/2" x 3-1/2" production packer • Set packer and MIT-T& MIT-IA to 3500 psi • Set a TWC and RDMO.

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. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Gerald Murphy, at 659 -5102. Sincerely, Mehreen Vazir BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

(BPXA), as Operator of the Initial Participating Area (lP A) within the Prudhoe Bay Unit (PBU), requested authorization to commingle a portion of the production from the IPA of the PBU with production from the Lisburne Participating Area (LP A) that is processed through the Lisburne Production Center (LPC). r-t" \~~-aC;~ Six IPA wells (L2-03A, L2-07A, L2-08A, L2-11, L2-13A, and L2-18A) located on the Lisburne L2 pad are currently connected to DS-18 by a pipeline and processed at FS-l. These six wells are currently cycled on and off, depending on whether their marginal gas oil ratio (GOR) is competitive with lower GOR production at the FS-I processing facility. Because the LPC is not currently gas- constrained, BPXA proposes to re-route this partially shut-in production through the L2 pad to the LPC processing facility and maintain full-time production from these wells. The Division of Oil and Gas (Division) approves BPXA's request to commingle production from the IPA with production from the LPA with the following conditions: (a) BPXA shall report production from the six IPA wells at the LPC as IPA production and include it on the IPA production reports; (b) BPXA shall report these volumes to the Division using selIing arrangement number 207002FOOO on the PRUD and PGAS accounting unit oil operator reports (01); (c) production from PBU IPA wells to the LPC shall be determined and allocated in accordance with the GPMA metering and allocation procedures; (d) NGLs removed from gas produced by these PBU IPA wells at the LPC shall be accounted for and reported as ¡PA NGLs; (e) BPXA shall provide the Division the appropriate NGL yield for IP A NGLs produced at the LPC within 10 days of the determination and provide the Division with the annual GPMA NGL allocation update; and (t) the updated Lisburne POD, due in June 2007, shall incorporate a description of operations associated with these six wells.

I had been waiting on Nabors 22E to get ready to test and managed to fit this rig in. The rig was ready to test when I arrived and the test was started immediately. All BOPE equipment was tested and passed with the exception of the #3 valve inside the hydraulic choke on the choke manifold, which leaked, was greased, cycled and retested "OK". The rig and its surrounding area were well kept and provided good access. Tim Krupa (Doyon Toolpusher) was on hand and provides for a good test of this rigs BOP equipment. SUMMARY' I witnessed the weekly test of the BOPE on Doyon rig #9 drilling Arco well #L2-11 in the Lisburne field. There was one failure observed. Test time 3 1/2 hours.

Pore pressure predicted from 9.6-9.7 ppg EMW. Mud weight will be at least 9.8 ppg before entedng these zones. Put River also expected to overpressured with a pore pressure of 10.1 ppg EMW. Mud weight will be 10.4 ppg prior to ddlling into this interval. With higher mud weights, awareness of differential sticking needs to be heightened. Pad is a known H2S pad. Possible shallow gas exists in the W, Sak sands (6416' MD), Seabee shales (7813' MD) and the Put River formation (8507' MD) No significant faults are expected to be encountered by the well bore. However, the production zones accessed by DS-18 are known to be highly faulted and severe cases of loss circulation have been experienced. 05/11/98 13'40 FAX 907 564 5193 BP EXPLORATION ~ AOGCC ~005 HAL Li-B [,)RTO N HA L L IBURTON ENERGY SER VICES 0900 Arctic l~oulev~rd / Anchor.~ge, Alaska 99516 / Tel: 907-344-2929 / Fax' 907-344-6746 To: Allen Sherritt From: Larry Wilger Date: April 27, 1998 Re: DS L2-11 Cementing Surface Casing Cemenfi..n.g Design Assumptions I, Bottom holeeireulating_~_emperature is +/- SOO F. : 2.

Well Design: I Horizontal Well Objective: L2-11 is planned as a Zone lB producer, horizontal well targeting a DS 18 BHL. This grassroots well will consist of drilling a 12 ~A" surface hole with 9 5/8" casing. The intermediate hole will be 8 ½" with 7" intermediate casing. The production interval will be 6" to TD. This well will be completed with a 4-1/2" L-80 solid ce- mented liner and 4-1/2" L-80 tubing. The proposed horizontal well will improve the drainage pattern and maximise standoff from the GOC. The installation of MLAS's may be requested for future coil tubing sidetracks.

ALL DEPTHS ARE MEASURED DEPTHS (MD) UNLESS OTHERWISE NOTED. 2. MWD RUNS 1, 2 ARE DIRECTIONAL ONLY AND A_RE NOT PRESENTED. 3. MWD RUNS 3, 4 ARE DIRECTIONAL WITH DUAL GAMMA RAY (DGR) UTILIZING GEIGER- MUELLER TUBE DETECTORS. 4. MWD RUN 5 IS DIRECTIONAL WITH NATURAL GAMMA PROBE (NGP) UTILIZING A SCINTILLATION DETECTOR. THE CHANGE FROM DGR TO NGP PROBE OCCURS AT 8605'MD, 8190'TVD, 5. MWD RUNS 9-11 ARE DIRECTIONAL, DGR, ELECTROMAGNETIC WAVE RESISTIVITY PHASE- 4 (EWR4). THE CHANGE FROM NGP TO DGR DETECTOR OCCURS AT 9475'MD, 8703'TVI). 6. ALL MWD RUN 10 DATA IS REAL TIME DATA OWING TO LOSS OF THE TOOL IN HOLE. 7.

THIS WELL REACHED A TOTAL DEPTH (TD) OF 11485'MD, 8671'TVD. SROP = SMOOTHED RATE OF PENETRATION WHILE DRILLING. SGRC = SMOOTHED GAMMA RAY COMBINED. SGRD = SMOOTHED GA_M/W_A RAY. SEXP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (EXTRA-SHALLOW SPACING). SESP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (SHALLOW SPACING). SEMP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (MEDIUM SPACING). SEDP = SMOOTHED PHASE SHIFT-DERIVED RESISTIVITY (DEEP SPACING). SFXE = SMOOTHED FORMATION EXPOSURE TIME. SRAT = SMOOTHED TOOL SPEED WHEN NOT DRILLING. CURVES WITH THE EXTENSION "M" DENOTE MAD DATA. $ File Header Service name ............. STSLIB.001 Service Sub Level Name...
