To replace the riser the pipeline between Anna and Bruce Platforms must be shutdown. In order to maintain oil production from the Anna Platform the associated gas will need to be flared. We have estimated that approximately 1700 mcfd will be flared for about 10 days on Anna. There may be an additional 600 mcfd flared on Bruce for one or two days when the pipeline pigs are placed in the line for spill protection. Every effort has been made to plan and engineer the project. All materials have been pre-ordered and are ready for installation. All reasonable problems have been considered and contingencies are included in the project plan. We conducted approximately 5 days of preliminary diving work on the pipeline to reduce the actual down time. This work included hydroblasting of all the sub-sea bolts and flanges to minimize the downtime and associated flaring. The sub-sea pipeline corridor near the platform was surveyed by divers and all debris was removed. We have pre-fabricated the sub-sea connection spool to minimize the construction (flaring) time. We selected special sub-sea pipeline ball joint connectors to reduce the number of dives and reduce the overall length of the project. All lifting and pulling loads have been pre-engineered and all rigging has been sized, tested and purchased ahead of time. Experienced diving contractors, engineers of several disciplines and a marine construction consultant have been employed to insure timely execution of the project. I will be on vacation from June 18 - 30. If you have questions during this time please contact Faye Sullivan at 263-7685. Thank you, Janet G.

In the email AOGCC requested Unocal outline steps taken to thaw the pipeline from the Anna and Bruce Platforms to the Granite Point Tank Farm (GPTF), and to document efforts to reduce flaring. The oil pipeline at the bottom of Cook Inlet routes from Anna Platform to Bruce Platform and then to the Granite Point Tank Farm. The oil line from the Bruce Platform to the GPTF is approximately 28,000 feet long. ' Prior to plugging between January 25, 1999 and February 1,1999, methanol was added to the oil pipeline (GP1) between Bruce Platform and the Granite Point Tank Farm each time a pipeline pig was shipped to reduce the freezing point. ' Despite our efforts, at 3:30 am on February 2, 1999 the GP1 oil line froze between the Bruce Platform and the Granite Point Tank Farm. Bruce Platform and the GPTF operators attempted to unplug the GP1 line by pushing on the line with gas pressure. In order to continue to produce oil, platform operators switched the oil .production over to the GP2 gas line. At that time Bruce Platform shut in approximately 400 mcfd of gas produced from well 17586 #9. ' From February 3 to February 8,1999 the GPTF continued to work with the Bruce Platform by alternating pressure on GP1 from the beach and the platform. The line remained plugged. ' Between February 9 and February 28, 1999 a construction crew was mobilized at the GPTF. Methanol was injected through a 3/8 inch stainless steel tubing reel with a jet nozzle down the line. During this time 1500 gallons of methanol was injected up to 600 feet down the line. The plug did not move. ' Between March 1 and April 20, 1999 alternating pressure from the shore and the platform was applied to the pipeline. Pipeline pressure was applied up to the maximum allowable operating pressure. During this time other ideas on how to remove the plug were discussed. With each one there was risk of a breach of the line, which could have led to a spill. These ideas were deemed unlikely to bring success and the environmental risk too high. L:\environ\air\facility\99AOGCC_GP l line. doc !'` ~ On April 21, 1999 after 350 psi from the Bruce platform was applied to the pipeline the plug broke free at 3:OOpm: A pipeline pig was sent through the line and the crude was displaced with gas. The GP1 line was placed back in service on April 23, 1999. The GP2 line was converted back to gas service. Gas well 17586 #9 was opened to production on April 24, 1999. From the first day of the event platform operators reduced the flare gas to volumes necessary for maintaining oil production. Casing head gas associated with oil production was used to provide heat to the platforms and run the equipment. The excess casing head gas from the oil production was flared in order to maintain safe operating conditions. Reservoir conditions and economics were considered during this event. Historically, shutting in oil wells on Bruce and Anna Platforms resulted in water encroachment and loss of production. Therefore, it was decided to maintain oil production as a means to minimize production lost. In the early 1980's, prior to Unocai operating the facilities, platform personnel recall the pipeline freezing. during an exceptionally cold winter. As a means to help prevent freezing in the future Unocal has implemented new technology and new procedures. Unocal has purchased 6 expandable pigs, plus an expandable brushing pig. The pigs will expand as the inside pipeline diameter changes from 4.9 inches to 6 inches. The expandable pigs will improve on how the water is swept out of the line. The frequency of pigging has also been increased. During this 77 day event every effort was taken to maintain a safe operation, protect the reservoir, minimize productions loss, and minimize flare volumes. Only casing head gas necessary to produce the crude oil was flared. Should you have further questions please direct them to Janet Bounds at 263-7694. Sincerely, 1dV Martin T. Morell cc: John T.

On July 9, 1999 AOGCC requested via email additional information regarding the pipeline conditions at the time of freeze up, the injection of methanol, and excess flare events on the Anna and Bruce Platforms after the pipeline was placed back in service. This email is a response to AOGCC's email communication. * Prior to the GPl pipeline freezing between the Bruce Platform and the Granite Point Tank Farm pipeline pigs shipped on January 18, 1999 arrived the morning of the January 19, 1999. Pipeline pigs run on January 19 and 20, 1999 failed to reach the shore. * At the time the GP1 pipeline froze the current activity was shipping oil to Granite Point Tank Farm. The average pressure at the time of freezing was 105 psi. * Three phase fluid separation occurs on each platform prior to entering the pipeline. The fluid composition entering the GPl line was crude oil with a trace amount of water (less than 0.5%). * Unocal began injecting methanol at a rate of 3 gallons per day in September. This is standard practice during the winter months. When the pigs failed to reach the shore the amount of methanol injected was increased as follows: 29 gallons on January 19, 23 gallons on January 20, 33 gallons on January 21, 58 gallons on January 24, 58 gallons on 30 and 58 gallons on January 31. After it was determined that there was no more .flow in the line the injection of methanol stopped when the pipeline froze on February 2, 1999. * Excess flaring on the Bruce Platform after the pipeline was back in service until May 31, 1999 was due to maintenance on the Vapor Recovery Unit, and the Solar Gas Compressor. The emissions on Bruce were also impacted for one day because the gas compressor at the Granite Point Tank Farm was down for maintenance. These maintenance events were planned and were not related to the frozen pipeline. * The Anna Excess Flare Logs for April and May contained a calculation error. Revised reports will be sent to you. The revised reports contain three events in April after GPl was place back in service and three events in May. The April events were due to cleaning out the gas line between Bruce Platform and Granite Point Tank Farm on April 23 -24, and 25, 1999. The events on May 7 and 17, 1999 were related to high gas pipeline pressure due to liquids in the gas line between Anna and Bruce Platforms. Unocal is currently in the engineering design phase of evaluating the installation of a gas line pig launcher and receiver in order to help clean liquids out of the line between Anna and Bruce Platforms. This work is pending the ability to remove equipment from the riser to the Bruce platform. The event on May 27, 1999 was due to scheduled annual. maintenance on the gas compressor.

Gas was flowing through the GP-2 line during that time also. The pipeline pigs were retrieved on April 28, 1999. Thank you, Janet G.
