Tarballs and an oil sheen were spotted on Lake Pontchartrain and in the Rigolets on Monday, prompting crews to put 600 feet of hard and soft boom at a “choke point”, to stop more oil from getting into the lake, according to government reports. More than 20 vessels responded to the site, collecting more than 1,000 pounds of tar balls and waste, which will be tested to see if it comes from the leaking Deepwater Horizon/BP well. The clean up operation continues today.
We’ve had to learn a lot while watching the excruciating efforts to cap the gushing BP oil well deep in the Gulf of Mexico.
The latest lesson on the chalk board is about deep sea pressures. The water pressure is so great at a mile below the surface that pumping material back into the ruptured oil pipe is an incredibly difficult feat. It calls for a special potion of drilling “mud” that can “lock up” against the force of the oil gushing out, and yet not freeze before doing its job or collapse at deep sea pressures and temperatures.
