Bracewell attorneys Jason Hutt and Matt Armstrong are guest blogging this week on the National Law Review website about hydraulic fracturing (“fracing”), which is the injection of a high-pressure fluid mix of water, sand and a proprietary mix into formations deep beneath the surface to release natural gas. Fracing has been used more frequently in recent years due to the discovery of massive natural gas reserves in unconventional coalbed methane and shale plays. Recently, two Congressmen key to the energy debate in Washington, D.C., brought more attention to fracing with letters of inquiry directed to eight energy companies. In this post, Jason and Matt discuss a few of the key legal and policy concerns related to hydraulic fracturing.
