No I wasn’t an accountant but you evidently have a problem with reading comprehension. Can you tell me the difference between sub-salt and pre-salt?
Oh, c’mon man. I was just pulling your chain. Although I have never worked offshore, I will take a gander. The salt in the GOM is Triassic in age. Two continents close together, restricted basin, blah, blah, blah. So, anything pre-salt, at least in the GOM would be Permian or older. There are a few scattered wells in East Texas that found scrawny pay below the salt but it is rare. Mostly red beds and Ouachita facies to the west.
As far as sub-salt, there has been ongoing plays in the GOM for two decades and probably Brazil or Nigeria but I don’t keep up with foreign oil. I believe Anadarko had the first discovery. Two words - Kirchhoff migration. The math is beyond my pay grade.
