Excerpt:

Regency Chief Executive Byron Kelley said in an interview that pipes out of the Haynesville region are largely full. Even the announced expansions by his company and others to carry an additional 3.6 billion cubic feet of gas a day out of the Haynesville Shale likely won't be enough. He expects four billion cubic feet a day or more of additional gas to be produced from the Haynesville Shale by 2012, so "we fully expect that we will go through a series of expansions."
