A video from BP showing how the relief wells for the leaking pipe in the Gulf are being drilled. This is similar in some ways to what Studio Cruz created for Potter Drilling (which can be seen here) but shows an actual rather than an idealized case. The technology is amazing: drilling a hole a mile underwater through three miles of solid rock to intersect a ten inch diameter pipe. The video is a good example of how informative animation can be used to explain concepts, not only to the public but also to the drilling crews themselves. About six minutes in all.
