Five workers are presumed dead, including one Texan, after an
explosion ripped through a drilling rig in Oklahoma, triggering the
nation's deadliest oil and gas incident in several years.
The drilling rig is owned by Houston-based Patterson-UTI
Energy, which employed three of the deceased. Patterson-UTI has grown
into one of the nation's largest onshore drilling and hydraulic
fracturing, or fracking, companies.
"At this time we have moved from a rescue mission to a
recovery mission," said Pittsburg County sheriff Chris Morris at a
Tuesday press conference. "They are waiting on the scene to cool down
and be stabilized before we can go in."
