Before rig explosion, BP pumped chemical mixture into well, contractor says

KENNER, LA. -- In the hours before the Deepwater Horizon drilling rig exploded, BP pumped into the well an extraordinarily large quantity of an unusual chemical mixture, a contractor on the rig testified Monday.

The injection of the dense, gray fluid was meant to flush drilling mud from the hole, according to the testimony before a government panel investigating the April 20 accident. But the more than 400 barrels used were roughly double the usual quantity, said Leo Lindner, a drilling fluid specialist for contractor MI-Swaco.

BP had hundreds of barrels of the two chemicals on hand and needed to dispose of the material, Lindner testified. By first flushing it into the well, the company could take advantage of an exemption in an environmental law that otherwise would have prohibited it from discharging the hazardous waste into the Gulf of Mexico, Lindner said.

The procedure mixed two substances. "It's not something we've ever done before," Lindner said.

A BP specialist said using the two substances together would be okay. Nonetheless, the night before the rig exploded, Lindner was busy conducting an improvised chemistry experiment to double-check. He mixed a gallon of one of the substances with a gallon of the other and observed their reaction.

When the well became a gusher on April 20, a fluid that fit the general description of the mixture rained down on the rig.

Stephen Bertone, chief engineer on the rig, said in testimony earlier in the day that part of the rig was covered in an inch or more of material that he said resembled "snot."

Ronnie Penton, an attorney for one of the rig workers, said in an interview after the hearing that the double-sized dose of spacer fluid, also known as a "pill," skewed a crucial test of pressure in the well just hours before the blowout. Based on the test, BP concluded it was safe to continue displacing the heavy mud from the well in favor of much lighter sea water.

"That large pill skewed the testing," Penton said.

The alleged departure from standard practice came despite a series of complications in the attempt to complete work on the well.

This just in...........

It's just been reported that BP posted a fake, Photoshopped picture of their crisis response center on their website.1

This is hugely troubling. If BP doctored a picture on their website, what else are they lying about? And why did they fake this picture in the first place? What are they hiding?

This also fits a pattern of stonewalling and misinformation by BP throughout this crisis. The public needs to know what's really going on—and a scandal like this can really increase the pressure for more transparency.

That's why we're calling on Congress to open an investigation into BP's faked photo and any other information they may have hidden or doctored. Click the link below to add your name to the petition:

The petition says, "Congress: We need an investigation to find out why BP posted fake photos of their crisis response center—and what else they're hiding."
