Apache Corp. reported Thursday that well control operations at a gas well 50 miles off the Louisiana coast have been completed.
The company detected a kick, or uncontrolled flow of fluid at the well on Feb. 4 and activated a blowout preventer.
That apparently stopped natural gas from escaping the well, but later tests detected the hydrocarbon had migrated from the bottom of the 8,300-foot hole to a shallower sand formation 1,100 feet below the sea floor.
Apache released a statement Thursday reporting that the bottom of the well had been plugged and cemented and the migration of natural gas to the sand formation had been stopped.
No injuries or impact to the environment were associated with the incident, the company said.
It said it is still evaluating the next steps for the well, which is located in 218 feet of water.
Apache is the largest producer in the shallow waters of the Gulf of Mexico shelf.
