The total is illusive because there’s a difference between recoverable oil and not plus not all of Bakken has been surveyed yet, as far as I understand it. New techniques were coming out during the Bush presidency but today O&G companies are cutting back on R&D as well as exploration because of the Democrats attack on their industry. Same thing is true off-shore. California has a ton of oil off-shore but refuses to allow drilling.
The Colorado O&G Commission has new rules too (Democrats, of course) and drilling here has dropped to reflect that.
It’s just a fact. Democrats oppose US energy independence while chasing the windmills in their fantasy world.
How much oil is offshore of Californy and what reason is there not to drill it to salvage the collapsed economy of the state?
