General The Gathering Center 3 (GC-3) and Central Control Room Operators will make every attempt to minimize and eliminate flaring. Flaring to maintain production is not allowed. The Control Room Operator will maintain close communications with GC-3 Operators to keep an updated status of K-5500 and related flaring. The Control Room Operator will coordinate with GC-3 Operators to ensure that specific actions are taken within established time guidelines. Any required production rate changes to minimize and eliminate flaring will be coordinated with the Eastern Operations Center (EOC) to coordinate production rate changes. Specific Action In the event of a shutdown of the GC-3 Wet Gas Compressor, K-5500, the following actions will be taken to minimize flaring: . If K-5500 shuts down, the flare gas assist valves will remain closed unless black smoke is observed (black smoke will not nonnally appear with K-5500 flaring). A period of up to one hour is allowed to restart the compressor or estimate the downtime for repairs. The flare rate under this mode will be approximately 4.3 MMSCFD. · If K-5500 has not restarted after one hour, CRC operators will decrease water rate in 10 mbwpd increments over the next four hours, by notifying F5-3 and pipe-lining water to them. This mode of operation will reduce flaring by approximately 0.6 mmscfd (roughly 3.7 MMSCFD) and will reduce purge gas through the on-line skim tank. · If K-5500 has not restarted after a total of four hours from when the compressor first shut down, GC-3 water rates are reduced to 50 MBWD by shutting in high water cut wells and all produced water is transferred from GC-3 to Flow Station 3. The online skim tank is shut down and isolated. The produced water surge tank, and the slop oil tank are also shut down. This eliminates all flared gas from the water handling facility and reduces flared gas volumes to approximately 2.2 MMSCFD. This mode of operation will be used for an additional three hours to allow further time for returning K-5500 to operation. Note: During very cold weather or during phase weather conditions, it may be prudent to continue flaring rather than shutting in high water cut wells. Shutting the wet wells under extreme conditions could increase the risk of frozen piping, spills, and personnel exposure. The Offtake TL, Field OTL, GC-3 OTL, and Operations Manager should discuss the situation before implementing this step. · If K-5500 has not restarted after a total of seven hours from when the compressor first shut down, all High Pressure production into GC-3 is shut down, eliminating flared gas from the condensate associated with high-pressure production. At this point flared gas volumes are reduced to approximately 1.8 MMSCFD. Production at the Gathering Center is now limited to relatively dry low-pressure production with all water routed to FS-3.

Estimated five to ten percent opacity with sporadic fifteen to thirty second puffs of black smoke. Most likely from small valve leakage from remaining safe out (volume too small to calculate, estimated at ten). Action Taken to Stop Flaring: 1. Started LPS compressor 7001 2. Equalized and opened Inlet to C slugcatcher 3. Started vent gas blowers and K5500 LP compressor 4. Allowed to continue as a SID would have likely caused a bigger black smoke incident.

Thursday, November 20, 2003 Page 1 of 1 Greater Prudhoe Bay Flaring Event Subject: Greater Prudhoe Bay Flaring Event Date: Sat, 15 Nov 2003 16:14:43 -0900 From: "GPB, Prod Opt TL" <GPBProdOptTL@BP.com> To: steve_mcmains@admin.state.ak.us Steve, Today GC3's wet gas compressor (K5500) shut down unexpectedly due to "loss of purge in the instrument cabinet". After reviewing the issues that will have to be dealt with in order to restart K5500, we have determined that the most efficient course of action is to replace the compressor immediately. In order to restart K5500 in its current condition we would have to open up the compressor to repair a stuck slide valve. Repairing the stuck slide valve would take, at a minimum, as much time as replacing the compressor with a strong likelihood of a longer duration. This course of action will enable us to confidently return the machine to service for the long term. We had already planned to replace the compressor in the summer of 2004 ~, due to a slowly deteriorating vibration problem. ' We will follow the agreed procedure for minimizing flared gas during K5500 shut down events. The final step in the procedure calls for full shut down of the plant if after 24 hours, restart of K5500 is not imminent. The current ambient temperature is -20F, with the forecast calling for lows between -20F and -30F through Monday. We feel that the most prudent course of action, under these conditions, is to allow GC3 to continue to flare (approximately 2 MMSCFPD) in order to keep the plant partially on line. Our best estimate is that K5500 should be ready for a restart Monday afternoon. When K5500 is back on line and the flaring event is over, I will submit a follow up note. If you have an questions, please do not hesitate to call me at 659-4472. Thank you, Hal Tucker Greater Prudhoe Bay Production Optimization Team Leader '1 of 1 11/16/20039:09 AM FW Grea"ær Prudhoe Bay Flaring Event Steve, GC3's K5500 flaring event, which began at 04:16 on 11/15, ended at 14:35 on 11/19. Total flare duration was 106 hours and 19 minutes. The total flared volume for this event was 9.874 mmscf. During the four day flare event, technicians had to go back into K5500 for two separate repairs, once to replace a leaking compressor mechanical seal and again to repair an excessive lube oil leak. The mechanical seal failure occurred during the initial restart attempt on 11/17 and required replacement of the mechanical seal. The oil leak was discovered prior to the second restart attempt on 11/18 and required replacement of a compressor slide valve "0" ring. K5500 was restarted and loaded up on 11/19 and has been running smoothly since then.. High pressure production wells were cycled on and off periodically during the four days to prevent flow line freeze up. Additionally, produced water was stacked in the skim tank and the produced water pumps brought on briefly each day to warm up injection wells and lines. If you have any questions, please do not hesitate to call me at 659-4472.
