Mike informed me that the BOP stack had just been over hauled and we may have a few flange leaks, but foresaw no major problems. The crew got ready to test at 10:00AM starting with the annular preventer, which tested OK. Next the top pipe rams were closed and the choke and kill line HCR valves were closed. The kill line HCR valve leaked - the manual kill was closed and the pressure was brought up to 5,000 psig. The ring gasket began to leak between the mud X and the lower pipe rams. ! departed the location after 2.5 hours of watching the crew hammer on the hub clamp. I returned to the rig at 5:00PM and the crew was removing the mud X. I told Charlie to give me a call when they were ready to test. At 5:10 AM on 8/26/95 Mike called and said was ready to test and had 5,000psig on the stack. I arrived at the rig at 5:50 AM and went to the rig floor- the crew was tightening a clamp on the choke line - it still leaked - the ring was removed and it was discovered that the wrong type had been installed. This was corrected and the test began again. The choke manifold was tested and then another ring gasket began to leak. ! again departed the location to do SVS test at another location. I returned to the location at 3:30PM and the crew was still testing. Everything had been tested except the blind rams, which were leaking - they were changed out and tested OK. The kill line HCR valve began to leak again - it was greased, cycled and retested OK. The * on the attached AOGCC BOPE Test Report denotes the items that l did not witness the testing of.

Fluid Handling: All drilling and completion fluids can be annular injected. Request to have well E-38 for annular pumping. Request to AOGCC for Annular Pumping Approval for E-38: 1. Approval is requested for Annular Pumping into the E-38 10-3/4" x 7-5/8" casing annulus. , Aquifers in the Prudhoe Bay Field Western Operating Area (including K Pad) have been exempted from Class II injection activities by the AOGCC by Aquifer Exemption Order #1 as referenced in Area Injection Order #3. There are no domestic or industrial use water wells located within one mile of the project area. 3. The 10-3/4" casing shoe will be set at 3657' MD (3645' TVD) which is below the Permafrost and in shale formations in the Sagavanirtok above the Ugnu Formation. . The burst rating (80%) for the 10-3/4" 45.5# NT-80 casing is 4,170 psig while the collapse rating (80%) of the 7-5/8" 29.7# L-80 casing is 3,830 psig. The break down pressure of the Ugnu formation is 13.5 ppg equivalent mud weight. The Maximum Allowable Surface Pressure while annular pumping is calculated according to the following equation and is 2215 psi for a 10.0 ppg fluid in this well (Assumes worst case in which 7-5/8" casing is filled with gas). MASP = 3830 psig - ((fluid density ppg - 1.9) X 0.052 X 10-3/4" Casing Shoe TVD) 5. A determination has been made that the pumping operation will not endanger the integrity of the well being drilled by the submission of data to AOGCC on 7/24/95 which demonstrates the confining layers, porosity, and permeability of the injection zone. 6. The cement design for this well ensures that annular pumping into hydrocarbon zones will not occur.
