The AOGCC Plug and Abandonment Test Report is attached for reference. Well 2-35 is being prepared for a sidetrack in the near future. Wireline was used to verify the location of the top of cement. Top of cement was located at 9,590' md, at this time the plug was pressure tested to 2,200 psi for 30 minutes - no bleed down. The final tag run was made following the pressure test and the plug was found at the same place - no changes.

The cement plug was bullheaded from surface down the production tubing to a calculated top of cement at 9580 ( actual cement top tagged with wire line at 8683 ). This method placed no cement above the packer in the 3.5" x 7" annulus. The top perforation is at 9820 and the production packer is at 9817. The plug was pressure tested to 1500 PSi for 30 minutes. Wire line was then run in the hole and cement tagged inside tubing at 8683. It was indicated that the minimum depth of cement for · I the planned side track operations is 9450' I informed Richard Ortiz with ARCO that.~ ~1~'~° "_ if the excess cement was cleaned out of tl~e tubing the plug would need to be retested, w~kn'~ I$~=.

The well~n question is D$.2.- 12A, and its numerical designation has been changed to DS 2-315'. Annular pumping approval for this well was granted by ADEC in a letter dated September 12, 1991. All other aspects of this well (pumping depth, start and stop dates, estimated volume, and surface location) will remain the same. If you have any questions regarding this change, please call me at 265-1547. Sincerely, David W. Hanson Permit Coordinator Prudhoe Bay/Lisburne Attachment L.
