Quote from tradestrong:
Read up on Ixtoc...the chances that they'll hit the bulls eye with the first relief well is very slim. BP wasn't even going to drill 2 relief wells but they were basically told they had better. 900 more feet would be the miracle scenario. And even still, like I said, it could still be months before the blown out well stops spewing even if they do hit the bulls eye the first time.
Here's a little historical perspective for you:
" What took them so long? Ixtoc workers drilled two relief wells, same as the current strategy of BP as stipulated by the Obama administration. In the case of Ixtoc, the first relief well did little good. According to Reuters , Ixtoc âcontinued to leak oil more than three months after Pemex completed its first relief well.â And in that case, Pemex, the driller, was able to shore up its efforts by pumping cement and water down the runaway well, something that cannot be done in the case of the BP spill. Pemex used divers to attempt to fix the blowout preventer, another option unavailable to us.
The earliest timeline for capping the Deepwater Horizon spill with the aid of a relief well was said to be August. This morning White House energy advisor Carol Browner told NPR, â90 days.â That puts us into September. But who is to say that estimate has any validity? Experience counters persuasively that more is likely to go wrong, that one relief well may be insufficient, and moreover, that even with two relief wells in place itâs not a done deal by any means. At Ixtoc, it took from March to May 1980 just to finish the job until the well was, as Priest put it, âofficially capped.â
At Ixtoc they were able to pump heavy mud into the two relief wellsâan option not available to us. Browner indicated that the relief well has to intersect some part of the original wellhead area, an operation that others have described as open heart surgery at 5,000 feet."

that was 1979....30 years ago!
Montara took 3 days once they drilled the well.
