Like the post below, this looks like good news, but we’ll know more in the coming days:

HOUSTON — BP said Wednesday it had brought pressure under control in its stricken well in the Gulf of Mexico after pumping heavy drilling mud into it, calling the development a “significant milestone” in its efforts to permanently seal the well.
The company began the effort, known as a static kill, on Tuesday afternoon and stopped pumping the heavy mud after about eight hours, saying that the procedure appeared to have reached the “desired outcome” of controlling pressure in the well.
If all goes well, cement may be applied to fill the well over the next few days.
“The well is now being monitored, per the agreed procedure, to ensure it remains static,” BP said in a statement on Wednesday. “Further pumping of mud may or may not be required depending on results observed during monitoring.”
The development comes on a day when the government is expected to announce that three-quarters of the oil from the Deepwater Horizon leak has already been eliminated, and the rest is so diluted that it does not seem to pose much additional harm.
