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.

The initial production rates were quality but, due to high initial gas rates, the well began cycling within a few months. A gas shut -off plug and adperf were completed in May 2002, but the production rates did not improve. Over the next 3 years, the well's production time was low due to recurring TxIA communication. The leak was finally addressed with a DSSSV in Oct 2006, indicating the control lines were leaking. The well produced until early 2009 when it was shut in for high GOR. In April 2009, CT rigged up to mill the CIBP but tagged collapsed liner at -11722'. Based on an MCNL run in June 2001, there was some up -hole adperf potential in Zone 2A and 2C. 15' of Zone 2A was added in the heel with a GSO of the lateral in July 2009. The well produced for about a year before reaching MGOR. In June 2010, another CIBP was added to isolate Zone 2A and 27' of Zone 2C were added. Unfortunately, the Zone 2C perfs '! produced only gas. The well is currently shut -in for high GOR. REASON FOR SIDETRACK Given the low oil rates and high GOR 02 -21A is a good candidate for a coil sidetrack. The proposed well will access a 50 acre target in SE DS 02. The proposed plan for 02-21A is to drill a through tubing sidetrack with the SLB /Nordic 2 Coiled Tubing Drilling rig on or around April 10th, 2011. The existing perforations will be isolated by a CIBP set pre -rig. The sidetrack, 02 -21 B, will exit the existing 7" liner and kick off in Zone 4 and land in zone Z2. The following describes work planned along with a schematic diagram of the proposed sidetrack. Pre -Rig Work: (scheduled to begin April 1st, 2011) 1. S PuII DSSSV 2. E Set CIBP at 10,920'MD V 3.

The well failed a TIFL on 01/18/05 with the TIO's = 2420/1840/610. Although the wellhead pressures have not exceeded the pressure limits, it is suspected they would do so if not bled by operations. The well was shut-in today due to ambient temperatures and management of gas production. Current plans are to: 1.SL: DGL Vs in sta#1 2. DHD: Re-TIFL Attached is the wellbore schematic.

The permit to redrill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

The sidetrack will be completed with a fully cemented 3 1/2" x 2 7/8" liner. Phase 1: Set whipstock and squeeze perfs. Planned for May 26-28, 2001 · The IA will be liquid packed and an MIT test performed. · E-line will set a whipstock at approx. 11,306'. · Service coil will use approx. 30 bbls cement to squeeze existing perfs. Phase 2: Mill window, Drill and Complete sidetrack: Planned for June 1, 2001. Drilling coil will be used to mill the window and drill the directional hole per attached plan. The sidetrack will be completed with a cemented liner. Phase 3: Install tubing patch Planned to follow the coil sidetrack operation. Mud Program: · Phase 1: Seawater · Phase 2: FIo-Pro (8.6 - 8.7 ppg) 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: · A combination 3 Y2" x 2 7/8" liner will be cemented to approx. 200 ft above the window with a minimum of 16 bbls cement. The top of the 3 Y2" liner will be inside the existing 4 Y2" tailpipe at approx. 10,320'. 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 2000 psi. Directional · See attached directional plan. Max. hole angle is 90 deg. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · An MWD Gamma Ray/Resistivity log will be run over all of the open hole section. A Memory CNL will be run inside the liner. Hazards The highest H2S recorded to date on DS 02 is 8 ppm. Lost circulation risk is Iow as no fault crossings are expected. Reservoir Pressure Res. press, is estimated to be 3350 psi at 9000ss. Max. surface pressure with gas (0.12 psi/ft) to surface is 2,270 psi. TREE = FMC GEN WELLHEAD= FMC ACTUATOR= KB. FIEV = 64' BF. ELEV = ?

(3) All Gamma Ray data (GRAX) and Resistivity data (RACLX, RPCLX, RACHX, RPCHX) presented is realtime data. (4) Well 02-21A was drilled as an open hole sidetrack on well 02-21. (5) The open hole sidetrack began at 11306' MD (8893' SSTVD). The hole was tied in with a Gamma Ray log from well 02-21 at 10782.5'. (6) Well 02-21A was drilled to TD @ 12408' MD (8994' SSTVD). (7) Baker Hughes INTEQ Run 3 utilized the Orient Express with Ultra Slim Multiple Propagation Resistivity (USMPR) services from 11455' to 11534' MD. Then the tool failed to transmit any resistivity data. Mud resistivity was 0.098 ob_mm / 150 F. (8)The interval from 12378' MD (8993' SSTVD) to 12408' MD (8994' SSTVD) was not logged due to sensor to bit offset. (9) The data presented here is final and was depth shifted to a PDC (Primary Depth Control) curve supplied by BPX (SWS, 10-Jun- 2001). (10) A Magnetic Declination correction of 26.79 degrees has been applied to the Directional Surveys.
