As the attached AOGCC Safety Valve System Test Report indicates I witnessed the testing of 15 wells and 30 comPonents with one failure. The Surface Safety Valve on Well 17-4 Failed to close on its initial test. After this valve was serviced and the · hyd lines flushed it operated properly and passed the retest. Mark Womble performed the testing today; he demonstrated good test procedures and was a pleasure to work with. I also inspected the wellhouses on this location while witnessing SVS tests. All the Wellhouses and associated equipment appeared clean and in good condition Summary: I witnessed SVS testing at BPX's PBU Drill Site 17.

The permit to drill 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) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

The option to long string the well will be evaluated after reaching the intermediate casing point ( 10' tvd above top of Sag River Formation ). Open hole conditions and mud weight requirements will determine the use of the Iongstring. Approximately 58 feet of Kingak shale will be exposed above the Sag River formation. Problems with this interval usually respond to moderate mud weight increases. The DS 17-20 well target is prognosed for the top of Sadlerochit ( ZULU flowunit ). There is no expected gas cap in the well. Faulting in the near target area is not a concern and a 250' target radius will be used. There is no evidence of geopressuring in the Cretaceous interval in the intermediate hole section and no preplanned increases in mud weight are recommended while drilling this interval. The completion will include 4-1/2" 13CR FOX tubing with dummied GLMs, one equalizing dummy, and one RP shear valve ANNULAR INJECTION The DS 17-16 & 15 surface annulus is available for injection at present. Fluids can also be injected at the central CC-2 injection facility. AOGCC has informed PB Drilling that only associated fluids from drilling operations can be pumped down the surface x intermediate annulus-ie: completion fluids cannot be pumped. FREEZE PROTECTION The 4-1/2" tubing along with the 4-1/2" annulus will be freeze protected with gas or diesel using the RP shear valve in the shallowest GLM. Dry crude needs to be injected down the 10-3/4" x 7-5/8" annulus after the well is completed. CLOSE APPROACHES/SHUT-INS Note near well' proximity of wells DS 17-4 and DS 17-5. 17-4 close approach occurs from 21' to 1394' md'. The SSSV will be shut-in. The well can be brought back on line once surface TD is reached. 17-5 close approach occurs from 21' to 3104' md. A plug will be set in the tail pipe and the SSSV will be shut-in. The well can be brought back on line once the surface hole is TD'd. Notify EOC coordinator when wells can be brought back on line.
