RE: San Juan Pigging/DRA

I spoke with San Juan early this morning and they indicated they would be running another pig this Wednesday.

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

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-
