Shale, a sedimentary rock abundant throughout much of the U.S., continues to be an important source for natural gas–one that’s fueling not just the energy industry but also some of the nation’s largest law firms.

Skadden, Arps, Slate, Meagher & Flom and Akin Gump Strauss Hauer & Feld picked up key advisory roles on a $742 million deal announced this week in the onshore oilfield services and natural gas sector, another $300 million shale deal received regulatory approval, and K&L Gates reshuffled its leadership to launch a new practice group devoted to capitalizing on energy and natural resources in the country’s lucrative shale deposits.
