Plug and Abandonment Operations Summary Upon completion of the drilling phase to the target bottom hole location and conditioning' of the borehole, open hole logging surveys were run. At the conclusion of logging the logging sonde became stuck at the top of the Sadlerochit. E-line cable was stripped over to the fish and the upper 22 ft. of the logging sonde was recovered. The next fishing BHA run made up to recover the rest of the fish encountered an obstruction at the bottom of the whipstock. After repeated unsuccessful attempts to find the sidetrack original hole the decision was made to plug and abandon the well. Verbal approval to plug and abandon was received from Blair Wonzell, AOGCC. An EZSV was set at 9792' and 31 bbls of Class "G" cement were pumped. A waiver was obtained from Blair Wondzell for the requirement to install the uphole bridge plug at 200'-300' in order to redrill the well to a revised target. A new permit will be submitted shortly for 14-2B. RECEIVED DEC 20 1993 Alaska Oil & Gas Cons. Commission Anchorage STATE OF ALASKA ~'' k,~ ALASKA ._,L AND GAS CONSERVATION CL. ....

I. Supervisor FROM: ~'~ug Amos, SUBJECT: Petroleum Inspector pgihlhad.doc Perforation Cement Plug Arco PBU DS14-2A Prudhoe Oil Pool PTD No. 93-168 Tuesday, December 7, 1993: I traveled to Arco's PBU DS14-2A well to witness the tagging of a perforation cement plug for the temporary P & A of this well. The well was abandoned after an unsuccessful fishing operation failed to remove all components of a Neutron Logging Tool. The Source was removed from the wellbore however 73' of the tool was cemented up in the abandoned bottom hole. The first attempt at tagging the isolation cement plug was unsuccessful. We RIH with drill pipe and stinger to 9,792', setting depth of the EZSV retainer and found no cement. We stung into the EZSV with the mud pumps running and immediately saw a pressure increase, indicating a successful cement squeeze job below the EZSV. Additional cement was ordered to lay the 75' cement plug on top of the EZSV. Wednesday, December 8, 1993: I returned to DS14-2A well a 1:00 a.m. and witnessed the tagging of the cement plug laid on top of the EZSV retainer. The cement plug was tagged with 10,000 pounds of drill string weight at 9,657', for a 135' plug. Summary: I witnessed the tagging of the perforation and fish isolation plug at Arco PBU DS14-2A well.

The permit to redrill 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) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

Pressure up on the 4-1/2" 12.6# 13CR80 tubing to 4000 psi to set the production straddle packer(s). Maintain tubing pressure at 4000 psi for 30 minutes after setting packer(s) and record as the tubing test. Bleed off 4-1/2" tubing pressure to +/- 1500 psi. Pressure test tubing x 9-5/8" annulus to 3500 psi for 30 minutes. Record the test on a Barton chart. Bleed off the annular pressure prior to bleeding off the tubing pressure. Bleed off the tubing pressure. Pressure up to 2900 psi on the annulus to shear out the RP valve in the top GLM position. Displace the tubing w/enough diesel to freeze protect the annulus to 2000'. Allow the diesel to U-tube to the tubing. If possible have the well freeze protected by gas by the PE's in the WOA or Drill Site Maintenance in the EOA. A potential gas source nearby will be required - high GOR well or artificial gas lift line.

AN UP PASS WAS ATTEMPTED & PRESENTED BUT WAS SUBJECT TO EXCESSIVE STICK & PULL. THE MLL & CALIPER WERE RECORDED ON THIS UP PASS. THE MLL AFTER LOG CALIBRA- TION WAS DONE WHILE TOOL WAS STUCK. THIS MAY ACCOUNT FOR POOR AFTER LOG VERIFICATION. THE UP PASS CALIPER DID NOT APPEAR TO BE LOGGING ON THE HIGH SIDE OF THE HOLE. THE ACOUSTIC MAIN PASS IS NOT VALID DUE TO TOOL SPEED AND A LOW GAIN SETTING (EXCESSIVE CYCLE SKIPPING). THE ACOUSTIC REPEAT PASS DATA IS VALID & IS USED IN THE FINAL EDITED DATA FILE FOR LDWG. CALIPER BEFORE LOG CALIBRATION WAS DONE IN THE 9.625" CASING DUE TO THE EXTREMELY COLD SURFACE TEMPERATURE. LONG TOOL LENGTH PREVENTED VERTICAL CALIPER CALIBRA- TIONS BEFORE RUNNING IN THE HOLE.
