One person was flown by helicopter to a Tulsa hospital with burn injuries. However five others were still missing Monday evening.

“We have searched the surrounding area and have not found anybody at this time,” said Kevin Enloe, the emergency management director for Pittsburg County.

On Monday evening, Patterson-UTI confirmed three of its employees were among the missing.

“We’ve reached out to their families and are providing support during this difficult time,” said Patterson-UTI Energy President & CEO Andy Hendricks in a statement.  “At this moment, no one knows with certainty what happened and it would be unwise to speculate. Well control experts and emergency responders are on site and we will conduct a thorough investigation when the incident is fully contained. We will provide updates as more facts are known.”

Officials with the Pittsburg County Sheriff’s Office say that the remains of all five workers were found around 2 p.m. on Tuesday.

The remains will be taken to the Oklahoma State Medical Examiner’s Office for identification.
