Because we're not totally sure of the root cause at this point, I can't tell you the exact path forward. I can tell you however that the long term plan does not involve K5500 being in service, as GC3 will be sending all emulsion to FS3.

Start safe out for cooler c/o. 2130 All HP wells choked to minimum (-30 F, approx 500 MM gas shut in). Test bank being utilized to rotate HP production for freeze protection. Move HP production to GC-1 Annex. 4/14/01 2400 Flare report started for 3/14/01. 1100 Mechanical safe out has been completed, still working to remove benzenes before allowing crew to start cooler work. Discussed status with GC3 supervisor this morning. Earliest re-start attempt is estimated to be late this evening (3/14).

GC3 is back to normal operations. Also, one note of clarification. In the first note I sent you below, I said that HP was shutdown at 13:30 on 4/10. It was actually shutdown at 12:30 which was 7 hrs into the event. Would you like me to fax you a copy of the flare report?

At its discretion, the Commission will either authorize the flaring or classify the flaring as waste. For each Gathering Center 3 event where gas was flared or vented less than one hour in September 2001, please provide the following additional information: (a) a brief description of the activity underway or problem troubleshooting associated with the flared volumes; and (b) a brief description of the action(s) taken to minimize the flared gas volume. In addition, please provide additional details/clarification on the 9/23/01 gas release from the C-35 slot. If well C-35 was shut in and its flowline was packed with dead crude, please explain why a ./ gas release occurred from the divert valve. Please provide a schematic which indicates the location of the divert valve. What future plans does BP have to prevent the seals on divert valves from leaking? We look forward to a written response by the end of the business day, Tuesday, January 15, 2002: Should you have any questions with respect to our information request, please contact me at 793-1231.

High gas transit line pressure caused by CGF compressor problems due to MI compressors shutting down at 07:40 hrs which caused high FSIM pressure. CGF lost their tandem compressor K-1883 at 09:53 hrs followed by CGF loosing their two booster compressors at 09:59 hrs. CGF lost another tandem compressor, K-1886, at 10:12 hrs. Action Taken to Stop Flaring: 1. Reduced rates to GC-3 by 80MM 2. WOA reduced production rates and shut-in several wells equaling 767 mmscfd. EOA reduced production rates and shut-in several wells equaling 904 mmscfd. Wells were shut-in or choked back starting at 07:45 hours. When CGF lost their tandem compressor at 09:53 hrs, EOC requested FS-1 Annex and GC-1 Annex to start flaring about 300-350 mm each. EOA & WOA continued to cut gas rates as CGF kept losing compressors. At 11:22 hrs, EOC advised that CGF had tandem compressor K-1886 on line.
