RANKIN, Texas (AP) — An oil field rig has exploded in West Texas, killing three workers.

Investigator Dusty Kilgore of the Upton County Sheriff’s Office said the accident happened Tuesday morning at a well site near Rankin, about 40 miles south of Midland.

Kilgore says one other person working at the well survived the blast and was not taken to a hospital.

He did not release the names of those killed.

The well is owned by Parsley Energy of Midland. Kilgore said a pulling unit crew was working at the site when the explosion happened, but he provided no other details.
