Note: Added Powder River Basin well on June 10, 2013
I don’t usually talk about “largest wells” in formations or plays because they aren’t representative of the productivity or economics of a play as a whole. With that said, it’s still good to know where the biggest wells are being drilled because that usually indicates there’s a lot of oil in the area (whether it can be extracted consistently and economically is another matter).
Note: Peak month rate oil/gas is the amount produced in a given month divided by 30 days.
