"Drilling specialists have been pumping heavy fluids into a gas well 50 miles off the Louisiana coast in a bid to halt natural gas moving among underground formations at the site."
"The intervention is taking place roughly two weeks after workers detected a kick, or uncontrolled flow of fluid, at the Apache Corp. well on Feb. 4. Although they activated a blowout preventer in response and apparently were able to keep natural gas from escaping the well, 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 spokesman John Roper said the Houston-based company was 'continuing our efforts to control the migration of gas in a safe and environmentally responsible manner.'
The company had contracted with the well control specialists at Boots & Coots, a Halliburton company, to try and kill the well, generally by pumping drilling muds into the well. That work is underway, according to the Bureau of Safety and Environmental Enforcement."
