I am attaching a profile of the efficiencies between Bloomfield and Bisti for Feb 22-
March 11. Summary 1) Before pigging, (i.e. 21-27th), the efficiency was about 96.5% 2) After the pig run on the 27th, the efficiency increased to about 102% for two days. 3) It averaged about 101% for the next 6 days (i.e. 28th-5th March). 4) It then steadily plummeted to 98% over a 3-day period - a percent degradation a day! (5th-8th March) 5) It remains around the 98% average today. Essentially, the high efficiency resulting from the 27th Feb pigging lasted just about a week. The targeted efficiency for this section is 103%. At the TW commercial meeting this afternoon, we indicated that applying the DRA around the end of May (together with other planned outages) may be the way to go. Meanwhile, I believe we should schedule another pig run as soon as we can. I did also receive the sample collected from the last pig run. I will have it analyzed and report on our findings. Please let me know any thoughts you may have on this issue ben Original Message----- From: San-Juan, Team Sent: Wednesday, February 27, 2002 3:04 PM To: Asante, Ben; Jolly, Rich; Roensch, David; Whippo, Jeff; Schoolcraft, Darrell Subject: San Juan Pigging We kicked a pig down the San Juan Lat. on 2-27-02 @ 08:03 MST Pressure was 1145 PSI, Flow of 840. It was a newly rebuild pig and was kicked dry. Bisti was down for 55 min, and the pig went by Bisti @ 10:26 MST. Data at each valve site retreved off RTUs. If you have any questions or comments, please call. Thanks, -Brian-
