Williams Launches Major WV Expansion to Serve Southwestern Energy

Yesterday Williams announced a new, major deal with Southwestern Energy to expand its network of gathering pipelines and processing facilities in West Virginia, to serve Southwestern’s increasingly aggressive drilling program in the state. Williams will expand its its Oak Grove processing plant to handle extra wet gas that will flow into it from Southwestern’s 135,000-acre wet gas (i.e. NGL) drilling program in Marshall and Wetzel counties. Southwestern targets wet gas in the Marcellus and Upper Devonian in those two counties. The expansion will give the Oak Grove plant the capability to process an additional 1.8 billion cubic feet per day of wet gas. But wet gas isn’t the only focus. Williams is also expanding its pipeline network to an additional 71,500 dry gas acres, again in Marshall and Wetzel counties, targeting Southwestern’s dry gas Utica program. In the same announcement, almost as an afterthought (but for us is a really big deal), Williams announced it will connect its system to Columbia Pipeline’s (now TransCanada) Leach XPress and Mountaineer XPress pipelines, “to boost market access and diversify gas pricing opportunities.” Leach XPress, which is part of a project including Rayne XPress, will send gas all the way to the Gulf Coast (see Columbia Gas: $1.75B for 2 Projects to Send Marcellus Gas to Gulf). Leach XPress began construction earlier this year. Mountaineer XPress will send gas to Leach, Kentucky (as will Leach Xpress), and from there on to a variety of other markets in the Midwest and South–as well as the Gulf Coast (see Details on Columbia Pipeline Mountaineer XPress Pipeline Project). Mountaineer Xpress received a favorable final environmental impact state from the Federal Energy Regulatory Commission in July of this year, but is still waiting on other permits before it begins construction. Here’s the news about Williams expanding in the Mountain State…
