It was shut-in about 4:00 AM this morning and is expected to be back in service about 8:00 PM. Approximately 7 MMCF of gas will be flared while the C-20 is down (rate = 13MMCFD) The oil system was shut in .for about 2 hours for scheduled maintenance during this period which reduced the flare volume. Specific duration of the event and volume of gas flared will be reported on the monthly flare log and excess flare report. If you have any questions, please contact Janet Bounds. at 263-7694.

TBPF 7/2 and 7/30 received grayling gas line pigs. Why two times in one month? What is the normal pigging frequency? Granite Point Platform 7/5-7, 14, & 16th Well spikes/Wireline work. What wells and and what kind of Wireline work? Steelhead 7/9-11/99 High Seal Vent pressure and C-20 seal failure. Was the seal already broken when the Seal gas regulator was adjusted, or did the seal break as a result of the adjustment? Other than that, things look great. The additional comments on the Steelhead flare log were very helpful, Thanks.
