In the Gulf of Mexico, BP's well is plugged and under control for the first time since late April.
Tuesday night, surface ships pumped heavy mud down a mile down into the well. The pressure leveled off over eight hours, and when the oil stopped surging BP stopped pumping.
The company could begin forcing cement into the well Thursday. To ensure it's killed for good, federal officials say relief wells still need to be completed.
As for the oil that’s already leaked out, a government study estimates 205 million gallons has disappeared.
The study reports 25 percent evaporated thanks to Mother Nature, 24 percent was dispersed naturally or with BP's chemicals and 25 percent more was either captured at the well, skimmed or burned.
