Apache moves to kill gas well after uncontrolled flow of fluid and gas migrated more than 7,000 feet

Apache moves to kill gas well after uncontrolled flow by San Antonio Express-News, February 16, 2013, mywesttexas.com
Apache Corp. evacuated 15 nonessential workers from a drilling rig in the Gulf of Mexico and hired specialists Boots & Coots to kill the well after tests found natural gas migrating below the seabed. … Problems first arose Feb. 4, when workers on the Ensco 87 jack-up rig detected a kick, or uncontrolled flow of fluid, in the well. In response, they activated a blowout preventer, which apparently was successful in keeping natural gas from escaping the well. Later testing showed gas had migrated from the bottom of the 8,300-foot well to a shallower sand formation 1,100 feet below the seabed. [Emphasis added]
