The ultimate solution for stopping the gusher is still a relief well. Two are being drilled in the Gulf of Mexico, one as a backup. The primary well, which was started nearly two months ago, had been drilled to about 16,770 feet below the water's surface by Monday morning. The well was about 900 feet above the point where it will intersect with the Macondo well, Wells said. But horizontally, the well is now just 20 feet away from the blown-out well, after beginning about half a mile away, Wells said.

I'd be interested to hear the technical reason for the shallow angle of approach of the first relief well.
To me the angle should simply be 90 into the side of the existing well or indeed I could understand if they came up from below if the plan was to fill the existing well with concrete.
The way they are shaping the entry it looks like they are intending to use the relief well as a main take off pipe and continue removing oil from the reservoir.
It could even be that they have no intention of putting mud and concrete down that relief well, instead they see this as an opportunity to make money from the oil.

I think they will use the first relief well to cap the damaged well, and then use the second relief well for a production well.

They are drilling horizontal wells, which means that the wells start at a vertical position but end in a close to horizontal position. It's a gradual curve...
there's no such thing as intersecting an existing well at 90 degrees.
And it wouldn't surprise me at all if they tap the existing well and put the new one in production. I'm sure the reason for two relief wells is one high, one low.
The low one brings the well online safely whereas the high one provides a kill to keep pressure from going through to the blown out BoP.
If they can bring the well online safely i say let them do it...they're gonna need the money for the lawsuits.
