Chesapeake Energy personnel are working with representatives from the Occupational Safety and Health Administration (OSHA) and the West Virginia Department of Environmental Protection to conduct an investigation into the May 20 incident at a Chesapeake operated drilling rig, NOMAC 241, in Wetzel County.

There were six workers affected and taken to Wetzel County Hospital; one was transferred to a different facility. They have all been released now. All of the affected workers work for Chesapeake affiliated companies.

The workers on the rig were exposed to a material during the drilling process that caused them to become nauseated.

Upon the workers’ arrival, WCH entered into a hazardous materials response. They set up and used a decontamination tent on site.

As of Friday, workers had finished removing and securing equipment that was in the wellbore at the time of Wednesday’s incident.
