Haul all Class I waste to Pad 3 for disposal. 17 -12A Permit to Drill Application Page 6 Drilling Hazards and Contingicies POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. The Sag River in this fault block is expected to be 7.0 ppg EMW. This pressure is estimated based on offset well pressures. 3500 psi test pressure is in accordance with the RP for Prudhoe production well casing tests for producing wells. B. Cretaceous produced water injection over - pressure is expected from the produced water injection in the UGNU Cretaceous sands. Most probable area is about + /- 5600'ss at 9.0 ppg EMW. C. The Shublik, because of its limestone lithology, may be more conducive to lost returns and stuck pipe if faults are encountered. When drilling the build section, monitor returns and hole conditions. D. Tight hole, swabbing, packing off and bridges, requiring normal working and /or washing and reaming occurred on most wells throughout DS 17. Most of these incidents were handled in routine operations. II. Lost Circulation /Breathing A. The 17 -12A is not expected to intersect any mapped faults. The placement of this well is driven by the fault system to the north and west. The nature of drilling parallel to a known fault may pose a low circulation loss risk. a. 17 -12 (1985) experienced a 200 bbls loss in the production hole at 11510', had to POOH and circulate out contaminated mud B. There are two major LC events on DS 17, both wells are southwest of the 17 -12A targets. 17 -19A (1997 Sag River Horizontal) lost +1 -6000 bbls after crossing a fault in the Shublik B at 8915 TVD and 17 -03 (1998) lost +/ -5000 bbls after possibly crossing a fault in the Sadlerochit Zone 4 at 9059 TVD. III. Kick Tolerance /Integrity Testing A. With the planned 9.3 ppg mud weight, the kick tolerance for the intermediate section is 107bbIs. With the planned 8.5 ppg mud weight, the kick tolerance for the production section is infinite. The FIT /LOT will prove up adequate formation strength for expected ECD's. B. Integrity Testing Test Point Test Depth Test EMW (lb /gal) type 9 -%" 20 -ft minimum from the 9-%" FIT 9.9 minimum window window 7" shoe 20 -ft minimum from the 7" shoe FIT 8.8 minimum IV. Stuck Pipe A. 17 -12 (1985) experienced stuck pipe in the intermediate hole after drilling into a coal bed at 6170' (4854' tvd), were able to jar free. B. Directional work will be required in the production hole section. Hole cleaning and differential sticking tendency will be of concern. Watch for signs of tight hole and short trip / back ream as required to avoid stuck pipe. 17 -12A Permit to Drill Application Page 7 ' VI. Hydrogen Sulfide • • DS 17 is designated as an H2S site.

The 17 -12A is not expected to intersect any mapped faults. The placement of this well is driven by the fault system to the north and west serving as baffles and the MI injector to the south (17 -13A). VIII. Anti - Collision Issues . A. Four wells (12 -05, 12 -06, 12 -06A and 17 -06) did not pass major risk criteria, a. Pass 1/200 minor risk criteria. TCR worksheets were completed for the wells. b.

Guy Schwartz Petroleum Engineer AOGCC 793 -1226 (office) 444 -3433 (cell) From: Medvedeva, Maria [mailto:Maria.Medvedeva @BP.com] Sent: Tuesday, December 29, 2009 1:30 PM To: Schwartz, Guy L (DOA) Subject: RE: 17 -12A (PTD - 209 -165) Good afternoon Guy, Sorry in advance for the confusion - I had not gone into details in the operations summary on the change out procedure. As part of step 19, we plan on setting a storm packer in the 9 -5/8" as the first barrier, and since we wouldn't have drilled out yet - we have the second barrier. You are correct, it is BP's policy to have two barriers in place and tested per flow path. As per the OA (9 -5/8" x 13- 3/8 "), we will have it open to a bleeder tank and monitoring for several days while drilling and casing the hole. We will be following the standard BP RP for Packoff change out since it is not possible to have 2 barriers in the OA. Does this answer your questions and clarify on the procedure?

I had a question about the tested barriers in place for pulling the tubing spool and packoff changeout mentioned on step 19. Can you elaborate on this ... I could be missing something? Do you normally have two tested barriers for as per BP policy?
