BP Oil Spill Cause: One Cause Halliburton Cementing Process
National Commission Finding On BP Oil Spill 2010: Halliburton Cement Mixture Recipe Flawed And Partially To Blame
It is the question that was on the minds of anyone who was following the BP oil spill in the spring of 2010.
What caused the BP Oil Spill? Well, the answer to the question what caused the Gulf Oil Spill goes beyond placing all the blame on BP.
Halliburton the oil services giant knew that the cement mixture recipe used in the Macando Oil Rig was faulty a National Commission investigating the BP Oil Spill has revealed.
The official name of the commission is The National Commission on BP Deepwater Horizon Oil Spill and Offshore Drilling.
The staff found that Halliburton—in charge of cementing the Macondo well—had conducted four laboratory tests that indicated the cement mixture standards wasn't up to industry standards. The results of at least one of those tests was given to BP on March 8, yet BP failed to act on it. Another Halliburton cement test was carried out about a week before the Deepwater Horizon blowout—and the test also found the cement was unstable—yet the results were never sent to BP.
Soon after the Deepwater Horizon caught fire and started leaking oil into the Gulf of Mexico, attention turned towards Halliburton, and its cementing process.
A BP investigation also placed much of the cause of the BP Oil Spill on Halliburton but Halliburton's prevous public statements said it tested and has used a proper cementing formula.
The lead investigator for the BP National Commission is Fred H. Bartlit Jr.
he makes clear in his letter that if the cement had done its job and kept the highly pressured oil and gas out of the well bore, there would not have been an accident.
“We have known for some time that the cement used to secure the production casing and isolate the hydrocarbon zone at the bottom of the Macondo well must have failed in some manner,” he said in his letter to the seven members of the presidential commission. “The cement should have prevented hydrocarbons from entering the well.”
The failure of the cement set off a complex and ultimately deadly cascade of events as oil and gas exploded upward from the 18,000-foot-deep well.
Halliburton says it is preparing a response to the commission's finding.
