HopeTracker| A familiar name is in the Gulf Oil Spill news. Without suggesting the the cause of the oil-drilling blowout — perhaps the worst in US history — is yet known, the Wall Street Journal focuses on Haliburton Co.,the oilfield-services firm that was handling the cementing process on the rig, which burned and sank last week.
According toLtd., the operator of the drilling rig, Halliburton had finished cementing the 18,000-foot well shortly before the explosion.
Regulators have previously identified problems in the cementing process as a leading cause of well blowouts, in which oil and natural gas surge out of a well with explosive force. When cement develops cracks or doesn’t set properly, oil and gas can escape, ultimately flowing out of control. The gas is highly combustible and prone to ignite, as it appears to have done aboard the Deepwater Horizon, which was leased by WSJPLC, the British oil giant. via
