These KOP's may be altered to enhance reservoir contact depending on the angle of intersection of each zone. b) Place 1 RA tag above each window exit. RA tags to be spaced out -40 - 80' above window depth except on the OBd lateral. It will need to be placed 120' above the casing shoe. c) Emergency 7-%" casing slips can be used instead of the 7-%" mandrel hanger if required for space out. 7-%" String Centralizer Placement a) Centralizer size: 7-%" X 9-%" (this is different then the norm of %" under gauge hole) b) Do not run centralizers on the window joints spaced at the top of each sand. c) Place 2 rigid straight blade centralizers back to back at the very bottom of the shoe joint. Do not run any centralizers on the next two full joints. d) With the exception stated above, alternate 1 rigid straight vane cenralizer floating across a full joint and 2 rigid straight vane centralizers, one floating on the upper half of the joint and one floating on the lower half of the joint separated by a stop collar up to ±4,370' MD (320' MD above the top OA sand). Then continue with 1 rigid straight vane centralizer per joint floating to 3,431' MD (780' MD above Ma sand). Zonal isolation with cement is required between the OA and the Nb sands due to the presence of water in the Nb sand. The centralizer program is subject to change pending modeling and hole conditions. 4%" Solid Liner Centralizer Placement a) Run one straight blade rigid centralizer per joint, floating between the collars. If any differential sticking is noticed while drilling, it may be necessary to put another centralizer per joint separated by a stop collar. Do not put any centralization on the first two joints above the bent joint.

Hydrates and Shallow gas A. Gas hydrates are present below V-pad, but have not been a significant issue thus far during V-Pad drilling. If hydrates are encountered follow the recommended practice and apply good drilling operational practices. III. Lost Circulation/Breathing A. Lost circulation is possible within the Schrader interval due to the reduced pore pressure. A LCM decision tree has been developed to give direction in the event of losses. B. We do not expect breathing on this well as we are above the more prevalent breathing shale's Le. Seabee. IV. Kick Tolerance/Integrity Testing A. The 10-%" casing will be cemented to surface. B. The 7-%" casing will be cemented with 15.8Ib/gal tail cement to 700' MD above the Ma sand -3,511' MD. C. The Kick Tolerance for the surface casing is 50.4 bbls with 9.2 ppg mud, 11.8 ppg LOT, and an 8.9 ppg pore pressure (most likely lower based on recent offtake within the block). If the LOT is less then 11.8 ppg EMW, then the kick tolerance will be < 50 bbls. D. The Kick Tolerance for the production hole laterals is infinite with 9.2 ppg mud, 10.5 ppg FIT, and an 8.9 ppg pore pressure. If the FIT is less then 10.5 ppg EMW notify the ODE to have conversation on how to deal with potential ECD concerns around the casing exit points. E. Note: FIT's will only be done on the first horizontal lateral due to pressure connectivity between subsequent laterals. F.

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. V-Pad is not designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. Recently 10 ppm of H2S has been measured at V-Pad from all wells tested as recently as January 2003 with hand held H2S meters. This is as a result of H2S being transmitted by shared gas lift gas and not produced from V-Pad. There has been no seawater injection at V-Pad to date. VII. Faults There is one planned fault crossing while drilling the well. It is possible to encounter sub-seismic faults along the proposed well path. In the production hole sections, if a fault throws us out of section steer up as fast as possible to determine where we are within the section. This will make it easy to lowside OH sidetrack to get back on course.
