HOUSTON – TEPPCO Partners, L.P. (NYSE:TPP) today announced a $45 million expansion of the Jonah System. The project will increase the gathering capacity of the Pinedale Field lateral and the mainline capacity of the Jonah System. The Pinedale Field lateral’s capacity will be increased from 55 million cubic feet per day (MMcf/day) to 250 MMcf/day. Mainline capacity of the Jonah System will be increased from 730 MMcf/day to 880 MMcf/day to handle growth from the Pinedale Field and significantly reduce operating pressures on the gathering lines in the Jonah Field.

“This project demonstrates the organic growth opportunities resulting from TEPPCO’s investment in Jonah,” said William L. Thacker, chairman and chief executive officer of the general partner of TEPPCO. “This project expands Jonah’s gathering capabilities into the emerging Pinedale Field and shows TEPPCO’s commitment to providing quality gathering services to the region’s producers.”


The expansion will include installation of 43 miles of 20-inch and 24-inch diameter pipe, 9,000 horsepower of compression and enhanced liquid handling facilities at two compressor stations. The project is expected to be completed and in service in fourth quarter 2002.
