So, what's with the hydrogen sulfide tanks? And yeah, I'd heard Anadarko was a "partner" in the blown out well. Many others too probably.
An aside; there have been a few oil and gas wells around these parts for decades but just in the last few years these newer sites have sprung up all around us. I gather at the depths you mention the cost to get at it until recently wasn't justified?
Horizontal drilling is what has made those wells profitable. They probably cost on the order of $6,000,000. The laterals go out over a mile from the surface beginning at 13,000'.
The only other partner in the well is Mitsui, a Japanese company with 10%.
