One contractor has died and three others have been taken by helicopter to hospitals in Houston and Austin following an oil well blowout in Burleson County.

That’s according to a spokesman for Oklahoma City-based Chesapeake Energy.

The deadly blowout occurred on the company’s worksite Wednesday afternoon along County Road 127 southwest of Caldwell.

First responders and an oilfield response specialist team remain on location and will likely be there overnight.

No names have been released at this time.

Burleson County authorities said the fire was reported at 3:30 p.m. on the Wendl and Daniel H 1 H well.

Representatives from Chesapeake Energy are also on-site investigating the cause of the blast.

The American Red Cross is also on the scene providing rehab to crews and first responders.

A spokesman for the Texas Department of Public Safety said no evacuations ordered but County Road 127 was temporarily closed immediately after the explosion.

Burleson County emergency crews received mutual aid assistance from multiple other agencies across the Brazos Valley including College Station Fire Department’s HAZMAT unit.

At 8:00 p.m. the roadway was back open but there is still heavy traffic from crews entering and leaving the worksite. It appeared the fire was out at last check.
