Finding itself ensnared in an enormous environmental lawsuit, Schlumberger Ltd. subsidiary M-I Swaco turned to Morgan Lewis & Bockius for help.

It turned out to be a wise move. On March 20, 2013, U.S. District Judge Carl Barbier of the Eastern District of Louisiana dismissed M-I from In Re: Deepwater Horizon. Morgan Lewis Houston partner Hugh E. Tanner said Barbier acted on M-I’s motion for judgment based on partial findings after the plaintiffs closed their case.
