So it turns out that viewers at home marveling at how much ‘mud’ was spewing from the leak were right, apparently something wasn’t working. The force of the mud was not enough to bring down the well pressure, which is the bench mark that starts the application of concrete. They have resumed pumping the mud, but are now injecting junk, or ‘bridging material’ into the mix. They have also been introducing junk and various other jamming materials into the BOP hoping to lower the pressure that way.
So it sounds like BP wasn’t able to force the mud deep enough into the well to plug it, but due to risks they probably started this process with the lowest estimated pressures to keep the pipe intact. Let’s see what happens when they put some weight on the pedal.

“This whole operation is very, very dynamic,” Doug Suttles, the company’s chief operating officer, told CNN’s “John King, USA.”
“When we did the initial pumping (Wednesday), we clearly impacted the flow of the well. We then stopped to monitor the well. Based on that, we restarted again. We didn’t think we were making enough progress after we restarted, so we stopped again.”
The light-brown material that was seen spilling out of the well throughout Thursday was the previously pumped fluid from the “top kill” procedure mixed with oil, he said.
