Since there is nof indication of integrity loss, it is acceptable to delay until the rig moves. Keep us informed as to the timing. I am not totally familiar with the upcoming schedule on other pads, but it would seem appropriate to look forward and determine if there could be some conflicts out there. Tom Maunder, PE AOGCC From: NSU, ADW Well Integrity Engineer [mailto:NSUADWWeIIIntegrityEngineer@BP.com] Sent: Fri 10/9/2009 3:11 PM To: Maunder, Thomas E(DOA); NSU, ADW Well Integrity Engineer Cc: Regg, James B(DOA); Schwartz, Guy L(DOA) Subject: RE: L-212 (PTD#2050300) and L-216 (PTD#2040650) Request for 4-Year regulatory testing extension Tom, The plan was to wait until two or three days before the L-212 and L-216 witnessed MITIAs were do to group them with the MITIAs for L-115, L-215, and V-104 (due 11/28/09) to save a trip for the AOGCC field inspector. In the past, the inspector had made the trip all the way out to L or V-Pad for one well inspection and we are trying to do a better job at scheduling these to respect their time. Unfortunately, the rig trucks began staging equipment and the activity on the pad became to congested to perform the work. The reason for not performing the MITIAs until the rig moves is because the area is extremely congested with the rig, rig camps, trucks, pipe racks, etc. The team is not comfortable conducting this work with the current activity on the pad and most of the current obstacles can be eliminated after the rig moves. There is rig equipment directly in front of wellhouses L-212 and L-216. Close proximity to Rig N-7ES is 45-90 feet in this case. I too would much rather have had these tested prior to the rigs arrival and I am embarrassed these have not been completed.

Why were these injectors not tested in advance of moving N7ES to L-223? Were there some extenuating circumstances that prevented the wells from testing earlier than the 4 yr anniversary date? Testing earlier is something that we clearly would not refuse. - What is it about performing the MIT that prevents you from testing with the rig in "close proximity"? - What is close proximity? Thanks in advance. I look forward to your reply.

Currently, Rig N-7ES is drilling L-223 and will follow by drilling L-222. These two injectors are in close proximity to the rig and do not allow enough space to safely perform AOGCC MITIA's at this time. I would like to ask permission to inject in both L-212 and L-216 until the rig has moved off L-Pad toward the end of October at which time the MITIA's will be immediately conducted. I have attached the Tl0 plot and wellbore schematic for each injector. «L-212.pdf» «L-212 TIO Plot.doc» «L-216.pdf» «L-216 TIO Plot.doc» Please let me know if you require anything else.

The Schrader in these two fault blocks are expected to be normal pressured to slightly underpressured based on offset well data. The Kuparuk in the pilot hole interval is expected to be normally pressured. II. Hydrates and Shallow gas A. Gas Hydrates are present at L-pad and have been encountered in offset wells throughout the SV4, SV3, SV2, and SV1. Setting casing through the SV1 should keep hydrate exposure from extending past the surface hole. * Recommended practices and precautions.for drilling hydrates should be followed in the surface hole. Occasionally hydrates are encountered below the SV1. / III. Lost Circulation/Breathing A. Lost circulation is unlikely within the Schrader interval. B. We do not expect breathing on this well as we are above the more prevalent breathing shale's Le. Seabee. IV. Kick Tolerancellntegrity Testing A. The 9-%" casing will be cemented to surface. B. The 7" casing will be cemented with 15.8 Ib/gal tail cement to 600' MD above the Ma sand. C. The Kick Tolerance for the surface ca~' is 6.2 bbls with a 10.2 ppg mud, 11.9 ppg EMW LOT, and an 10 ppg pore pressure (most likely 9.8 ppg). 51.7 bl Kick Tolerance is achievable with a12.8 ppg EMW LOT. Ifthe LOT is less then 11.9 ppg EMW, th . e kick tolerance will be < 25 bbls and will require ADW Manager ~ Approval. D. Integrity Testing V. Stuck Pipe Ä. We do not expect stuck pipe. B. There could be slight differential sticking across the reservoir while running the slotted liners. Keep the liners moving as much as possible and run one centralizer per joint to help with standoff. VI. Hydrogen Sulfide A. L-Pad is not designated as an sit ,however Standard Operating Procedures for H2S precautions should be followed at all times. Recentl 10 PB of H2S has been measured at L-Pad from all wells tested as recently as January 2003 with hand held . eters. This is as a result of H2S being transmitted by shared gas lift gas and not produced from L-Pad. There has been no seawater injection at L-Pad to date. VII.

Method of analvsis: 1. A list of wells to be analyzed is created in Compass by performing a global scan with an initial search radius of two thousand feet with an increment of one hundred feet for every one thousand feet of measured depth in the subject well. 2. Wells are analyzed using the Compass Anti-collision module (BP Company setup) with major risk safety factors applied. For problem wells that are plugged and abandoned or that can be shut in, risk-based safety factor may be used, with client notification. 3. All depths are relative to the planned well profile. Survey Proqram: Instrument Type MWD MWD + IFR + MS Start Depth 28.50'md 28.50'md End Depth 1,400.00'md 14,262.52'md Close Approach Analvsis results: Under method (2), all wells may flow.

Method of analysis: 1. A list of wells to be analyzed is created in Compass by performing a global scan with an initial search radius of two thousand feet with an increment of one hundred feet for every one thousand feet of measured depth in the subject well. 2. Wells are analyzed using the Compass Anti-collision module (BP Company setup) with major risk safety factors applied. For problem wells that are plugged and abandoned or that can be shut in, risk-based safety factor may be used, with client notification. 3. All depths are relative to the planned well profile. Survey Proqram: Instrument Type MWD + IFR + MS MWD + IFR + MS Start Depth 28.50'md 4,160.65'md End Depth 4,160.65'md 8,803.12'md Close Approach Analysis results: Under method (2), all wells may flow. All data documenting these procedures is available for inspection at the Drilling & Measurements Directional Planning Center.
