An inadequate underwater cement job during the deepwater drilling process is emerging as a potential cause of the devastating oil spill off the Louisiana coast in the Gulf of Mexico.
Officials haven't said what they think caused the April 20 explosion that led to the sinking two days later of the SSV Deepwater Horizon drilling rig, owned by Transocean Ltd. But industry speculation points to a process where cement is used to seal cracks in the ocean floor surrounding the tubing through which crude oil flows.
Transocean operated the drilling rig under contract for British oil giant BP Plc., the largest oil producer in the U.S. portion of the gulf and a company with a spotty safety history. Transocean has said the global construction titan Halliburton had just completed "cementing" the 18,000-foot-long well around the time of the explosion.
In a statement April 30, Halliburton confirmed that it was the "cementer" hired for the job and said it had completed its job about 20 hours prior to the explosion.
"The cement slurry design was consistent with that utilized in other similar applications," the company said. It said all procedures had been "in accordance with accepted industry practice approved by our customers."
"It is premature and irresponsible to speculate on any specific causal issues," the statement said. |
