BP’s petroleum engineering expert witness testified this week that the company was drilling safely before the Deepwater Horizon disaster. Retired LSU professor Adam T. Bourgoyne Jr. is president of Bourgoyne Enterprises, Inc. and active as a professional petroleum engineer. He described the Deepwater crew as following normal industry practices at the Macondo well. U.S. District Court, Eastern District of Louisiana judge Carl J. Barbier is hearing the case. In a separate trial, two BP well supervisors are charged with manslaughter in the deaths of eleven workers.
