Aerial footage from midday Monday showed several fires still burning at the site and the derrick, a towering metal structure above the well, collapsed onto the ground.
Morris said his office received a call regarding a gas well fire around 8:45 a.m. Monday morning. The OHP said firefighters planned to bring nitroglycerin to the site which would apparently be used to try to blow the flames out.
FOX23 sent out the alert around 9 a.m., when Pittsburg County Emergency Managers and the County sheriff confirmed an explosion and fire. A Tulsa medical life support helicopter landed near Quinton High School's Event Center.
He says the fire is mostly containing itself on site, where several tanks and other equipment are located.
The company says it was a drilling rig, but they are not sure exactly what it was drilling for. "We are letting the fire run its course".
A primary explosion on one well head led to fires on three wells in last year's well incident, but Enloe said the two events had different circumstances.
Officials say the rig drills for natural gas and oil. "The other one was production well where they were doing some work on a well and it caught on fire".
Enloe reports, "The experts are working on shutting off the well, the remote switch to shut down the blowout preventer is inoperable".
The cause of the explosion is still under investigation.
Sherriff's officials say the fire continues to burn, but it appears to be contained. "I pray there's not, but we just don't know yet", she said.
According to the Oklahoma Corporation Commission, the well site is operated by Oklahoma City-based Red Mountain Operating.
"We are not trying to spread water on it, and spread hazmat, because there are going to be contaminants on location", said Enloe.
Five employees working on the rig are unaccounted for, Pittsburg County Sheriff Chris Morris told the McAlester News-Capital.
