This year, Pamela Bleyl, 49, was killed in an incident at an Exxon shale oil production site in West Texas.
An employee of oilfield services provider Liberty Energy Inc, Bleyl was crushed between two pieces of equipment while working in Martin County, according to a negligence lawsuit filed in April in Harris County district court in Houston.
“We are very sorry this incident occurred, and we continue to express our deepest sympathy to Pamela’s family and friends,” Macdonald said, adding safety is a priority for the company and “the core value at all of our operations and facilities.”
