An explosion over the weekend at a natural gas well site in West Virginia operated by Antero Resources injured at least five people, prompting state and federal investigations, local officials and Antero said on Monday.
A spark triggered a flash explosion and a fire after a problem occurred while flowback fluids were being pumped into storage tanks. Two storage tanks exploded at 4 a.m. EDT (0800 GMT) on Sunday, according to Antero spokesman Alvyn Schopp. Five workers were taken to hospital with burns, he said.
“We do not know the ignition source, but we suspect it was a methane explosion,” said Schopp, vice president at Antero, an oil and natural gas company controlled by Warburg Pincus LLC .
