And the oil keeps flowing

Best Chance To Stop Leak Won't Be Ready Until August

The best hope for stopping the flow of oil from the blown-out well at the bottom of the Gulf of Mexico has been compared to hitting a target the size of a dinner plate with a drill more than two miles into the earth, and is anything but a sure bet on the first attempt.

Bid after bid has failed to stanch what has already become the nation's worst-ever spill, and BP PLC is readying another patchwork attempt as early as Wednesday, this one a cut-and-cap process to put a lid on the leaking wellhead so oil can be siphoned to the surface.

But the best-case scenario of sealing the leak is two relief wells being drilled diagonally into the gushing well – tricky business that won't be ready until August.

Welcome to the Summer of Environmental Disaster.
