A potentially dangerous oil well blowout at a Chesapeake Energy site in Wymoing caused at least 60 and perhaps 70 residents to evacuate within 5 miles of the disaster for several days until it was contained earlier today. Chesapeake Energy (NYSE: CHK) was drilling the well in the Niobrara Shale region underlying parts of Wyoming, Colorada and Nebraska.
“Potentially explosive methane gas roared from the ground at the site five miles northeast of the town of Douglas,” the AP reported.
Residents reported hearing the roar of escaping gas six miles away.
The blowout occurred Tuesday afternoon at Chesapeake's Combs Ranch Unit well site. However, workers were unable to plug the well with drilling mud until today due to shifting winds that made the site too dangerous to attempt the now infamous “Top Kill” technique. Halliburton subsidiary Boots & Coots workers were able to shove enough mud and other materials into the well to finally stop the methane gas leaking out of the well today.
Chesapeake had to resort to the “Top Kill” technique last year at a Pennsylvania gas fracking well blowout. In that case, Chesapeake used a junk shot of “a mix of plastic, ground up tires and heavy mud to plug the well.”
