FIRESTONE, Colo. (CBS4) – Anadarko Petroleum Corporation has released a statement saying the company is shutting down wells after a fatal house explosion in Firestone.

On April 17 a two story home on Twilight Avenue collapsed and went up in flames. Mountain Range High School science teacher Erin Martinez and her husband Mark were inside along with two others, Mark’s brother-in-law Joseph William Irwin III and a child.

Mark Martinez and Irwin were killed. Erin Martinez was badly burned.

“Anadarko operates an older vertical well that was drilled by a previous operator in 1993 and is located approximately 200 feet from where the home was recently built,” the company said in a statement. “As such, the company has been working cooperatively with fire officials and state regulatory agencies in their investigations since the time of the accident.”

Anadarko says the cause of the explosion remains under investigation but the company, which operates more than 3,000 vertical wells, has “taken proactive measures to shut in all vertical wells across the counties in northeast Colorado where it operates.”

The wells will remain closed down until “field personnel can conduct additional inspections and testing of the associated equipment.”

According to Anadarko, the wells it’s shutting down produce the equivalent of 13,000 barrels of oil a day. A barrel is 42 gallons.
