Williams and Duke Energy Field Services Agree to Swap Selected Midstream Natural Gas Interests

TULSA, Okla. – A unit of Williams (NYSE:WMB) and Duke Energy Field Services have agreed to an exchange of natural gas gathering and processing interests located in Wyoming, Texas and Oklahoma.

Under the agreement, Williams receives Duke Energy Field Services’ 34-percent interest in the Echo Springs processing plant and related gathering system near WamsutterWyo. In addition to operating the facilities, Williams already owns the remaining 66-percent interest in the Echo Springs complex and just finished expanding its capacity to almost 400 million cubic feet per day.

Steve Springer, senior vice president of Williams’ midstream gas and liquids group, said, “We continue to increase our stake in Wyoming because it’s a significant growth basin for producers. New supplies of natural gas create even more demand for our gathering and processing services in the area and also add value to other Williams’ businesses like energy marketing and trading and pipeline transportation.”         

In exchange, Duke Energy Field Services will receive certain assets including Williams’ Oklahoma Hugoton gathering system, and the Baker, Hobart Ranch and South Bishop gas processing plants located near Baker, Okla., Canadian, Texas, and in Ellis County, Okla., respectively.

“These assets are a great strategic fit with our assets in the area, as they will specifically provide supply to plants with existing capacity” said Michael Bradley, senior vice president, Duke Energy Field Services.  “This asset exchange supports our growth strategy of optimizing and rationalizing assets and allows us to offer more service options to our customers.”

The transaction is expected to close during the first quarter of 2002.
