Several (4) high FGOR wells were immediately shut in to mitigate flaring. As these wells worked out of the system and lowered the header pressure other wells picked up gas flow. Additional wells wire then shut in to mitigate flaring. Flaring was reduced to a minimum but required even more wells to be shut in to get completely off the flare.

An unplanned shutdown occurred on the C pad IWAG compressor due to problems with the Trabon lube oil pump system. Repairs were performed and the shutdown was extended to perform lap nned commissioning work on the new gas injection pipeline to L/F pads. The second two flare events were unplanned and due to excessive gas flashing off the 2na and 3ra stage separators in conjunction with an unplanned shutdown on the C-5531 compressor. Flaring was in low volumes & seemed to be insensitive to cutting high GOR production. This is an unusual occurrence at MPU and hence did not fit into any of our customary optimization schemes for reducing flare volumes. After a bit of troubleshooting, it was determined that the carryover problems were due to unusually low processing temps on the 1St stage slug catcher. Low processing temps were caused by a planned H-2603 heater shutdown for repair. The heater was returned to service pending C-5531 repairs and the flaring subsided. High GOR wells B 10, B 15, C 13, C 14 remained shutin throughout the day to mitigate excessive flaring.

A gas leak was discovered in the compressor building that required inspection/tightening of fittings. It was necessary to shut down the compressor to safely work on the'associated piping and fittings. The work was expedited and the compressor returned to service as soon as possible.

Once the fault was repaired on the turbine, gas compression was returned to service and the flare was eliminated. Black Smoke was reported with this incident, and all reports completed and sent to the ADEC. • Flaring Incident Report (exceeding 1 hour) BP Exploration -Milne Point June 12„ 1997 • Time and duration of incident: 23:02 hrs -13 hrs 1 min (June 11 to the 12`h) Flare Volume: 999 MCF Assist Gas Volume: 4274 MCF This was an unplanned flaring event which occurred when the 08 turbine shut-down due to a high temperature on the turbine exhaust, causing a field wide production shutdown. While attempting to bring gas compression back on line, we experienced a LSHH in the gas lift scrubber which tripped and shut-down the gas compression module again. Once the problems with the turbine and the gas lift scrubber were repaired the field was returned to full production and the flare was eliminated. • Flaring Incident Report (exceeding 1 hour) BP Exploration -Milne Point June 16, 1997 Time and duration of incident: 16:41 hrs - 6 hrs - 4 min Flare Volume: 565 MCF Assist Gas Volume: 2409 MCF This was an unplanned flaring event which occurred when the C-5501/11-A gas lift. compressor lost power to the local alarm panel in Mod. 55. Maintenance crews had problems identifying the problem. Once the problem was corrected with a 24 V breaker the Compressor was returned to service and the flare was eliminated with no further incident. • Flaring Incident Report (exceeding 1 hour) BP Exploration -Milne Point June 23 & 24, 1997 • Time and duration of incident: 1958 hrs (6/23) - 4 hrs 48 rains Flare Volume: 426 Assist Gas Volume: 2147 (carry over past midnight from 6/23 to 6/24) This was unplanned flaring following a main power generator unexpected shut down. The power generation package, singularly carrying full field load, shut down on an automatic control system malfunction. Extensive trouble shooting was required prior to returning the power generator to service. The other main power generator was out of service for a gas turbine engine exchange and governor control system upgrade. Start-up conditions were achieved and main power restored Time and duration of incident: 0727 hrs (6/24) - 5 hrs 52 rains Flare Volume: 402 Assist Gas Volume: 2244 This was unplanned flaring from two separate events. The gas compression module in the CFP shut down. One main compressor shut down on a lubricator low flow alarm and the other compressors consequently shut down from a transient pressure spike tripping a high pressure safety switch. The condition was verified safe and the compressors restarted as soon as possible. The C-pad gas reinjection compressor (1WAG) required unplanned repairs when the engine cooling system malfunctioned, causing the compressor to shut down. Repairs were expedited and the compressor returned to service as soon as possible. • Flaring Incident Report (exceeding 1 hour) BP Exploration -Milne Point June 29, 1997 Time and duration of incident: 1516 hrs 5 hrs 55 mins Flare Volume: 392 Assist Gas Volume: 2258 Time and duration of incident: 2218 hrs 2 hrs 27 mins Flare Volume: 231 Assist Gas Volume: 562 • Both of these events were unplanned flaring following unexpected gas compression module shut downs. The C-pad gas injection compressor shut down along with the main facility compressors. Production rates were reduced until the compressors could be restarted. • BP Exploration (Alaska) Inc. 900 East Benson Boulevard P.O.

One gas lift compressor was scheduled for maintenance repairs and a number of wells had been shut in to reduce gas plant throughput. However when the stop button was pushed to shut down one compressor all gas lift compressors shut down. This resulted in a cascade effect that also shut down all plant re-injection compressors and the field re-injection compressor for a total gas handling shut down. Additional wells were shut in at this time. Purge cycles would not initiate for a re-start until automation was able to trouble shoot the cause and resolve the situation. An automated valve signal failed on one start up attempt, E-pad gas handling re-set held out re-start attempts, gas plant pressure switch setting stopped several re-start attempts. • Flaring Incident Report (exceeding 1 hour) BP Exploration -Milne Point Apri120, 1997 Time and duration of incident: 1112 hrs - 5 hr 20 min Flare Volume: 279 MCF Assist Gas Volume: 1612 MCF • This was an unplanned flaring event when the IWAG injection at C-pad shutdown due to an oxygen analyzer wiring problem.

Once repairs were made on (H-2601), the Process Heater was returned to service and IWAG put back on injection. Maintenance crews continue to work on problem with H-5303 (New Process Heater) which appears to have a leak in the fire tube.

Maintenance crews had to make repairs several times due to leaking gaskets on the valve cover gaskets of the 3`d stage cylinder of compressor. Additional production was shut-in to mitigate excessive flaring and assist gas was utilized to eliminate any black smoke from the flare tip. Once repairs were successfully made on the IWAG injection compressor around 1800 hrs, there was another problem with accessing fuel gas to the compressor due to the shutdown of the C-pad process heaters. Maintenance crews continued to work on correcting the problem with fuel gas to the IWAG compressor. Once corrected 1WAG compressor was brought on line at 2200 hrs and the flare was eliminated. • Flaring Incident Report (exceeding 1 hour) BP Exploration -Milne Point March 15, 1997 Time and duration of incident: 04:34 hrs - 19 hrs 26 min Flare Volume: 687 MCF Assist Gas Volume: 3993 MCF This was an unplanned intermitting flaring event which occurred when the 1WAG Injection Gas Compressor at C-pad shutdown due to high temperature in the 3`d stage suction of compressor. Attempt was made to restart, but was unsuccessful. Maintenance crews made every attempt to expedite the start-up of the unit, but repair is taking longer than initially anticipated. Production wells were shut-in across the field in order to mitigate excessive flaring. The Injection compressor is still down at 0600 on the 16`h' due to a gas leak, which was caused by a gasket failure and was identified during an attempt to re-start compressor at 0300 hrs. Once identified that the injection compressor would be down for longer than anticipated additional production was shut-in to eliminate flaring. Maintenance crews are gathering materials to repair the gasket on the 3`d stage suction cylinder and operations is in the process of completion of a safe-out so the unit can be worked on again. Estimation of compressor downtime is unknown at this time, but expectations are to return to service as soon as safely possible.. • Flaring Incident Report (exceeding 1 hour) BP Exploration -Milne Point March 7, 1997 Time and duration of incident: 0614 hrs - 1 hr 16 min Flare Volume: 83 MCF Assist Gas Volume: 360 MCF This was unplanned flaring as a result of an unexpected shut down of the C-pad gas injection compressor (IWAG).
