Energy Sector's Unnatural Disasters
It has been more than a month since the April 20 explosion at the Deepwater Horizon oil rig in the Gulf of Mexico that killed 11 people. At the time of this write-up, British Petroleum made little headway with its much touted ‘top kill’ method to ‘kill’ or plug the leaking well from gushing oil. The method began on May 26 (only to be suspended for nearly a 16-hour period after the first ten hour of operation) with remote control submersibles pumping ‘drilling mud’ – a mixture of synthetic petroleum and clays – into the renegade well. BP engineers temporarily shutdown the ‘top kill’ operation when they saw that too much of the drilling fluid was escaping along with the oil. To overcome the high pressure of the gushing oil and gas from the well, the mud will have to be pumped countercurrent not only at a higher pressure but also at a higher flow rate. Under 30,000 horsepower of hydraulic pressure, the mud is expected to push into the leaking drill hole, stopping it up. Once the leaking s...
