They need that vertical column of 12,000 ft to give the kill mud enough weight to press down on the oil. They're not going to pressurize the mud in, it's the weight itself that squeezes the oil and gas back into the formation.
Also, if the relief wells are close to the oil and gas, then it's much cheaper to convert them to production wells in a year

These diagrams show me that the pipe bent vs snapped off the BOP and anywon who has ever used a garden hose knows that if you need to stop the water fast, just bend.kink the hose. Why haven't they used the giant claw machines to crimp the pipe in several spots, at least to slow down the flow?
Just wondering...

The pipe did kink, but it's nearly cracked all the way through. It's a heavy wall pipe, not designed to bend at all. Once it did bend, it cracked from the stress, and exposed non-treated metal inside the wall. that is quickly corroding and disintegrating. as well, when they did the "top kill" the whole thing got pressurized, and they blew several new holes open in it. If they took the claw and crimped it, it would crack completely open.
They've given up on "stopping the flow". They've stated that the flow won't stop until the relief wells hit, until then they're going to recover as much oil as possible (snicker...).
