$this->bbcode_second_pass_quote('Pops', '')$this->bbcode_second_pass_quote('Tanada', 'T')he latest EIA data I can find says that fracking in the USA produced 2.67 billion barrels of petroleum and natural gas liquids in 2020. Watching the URR number doesn't seem to help much as every time the price dips the number plummets because it is based on economically recoverable oil.
Only companies under SEC rules must report 1P provable (economical) reserves. Every year they change, because every year more are proven to be workable. But, everyone else just makes them up. You'll remember the fight of the paper barrels where each OPEC producer doubled their reserves overnight and hasn't revised them in decades. The reason is their reserves determine their quota. and of course they aren't audited.

$this->bbcode_second_pass_quote('', 'O')il reserves are reported following different classifications in use (JHL 2007)
US: all energy companies listed on the US stock market are obliged by the SEC to
report only proved reserves (1P), assumed to be the minimum (reasonable certainty if
deterministic or 90% probability if probabilistic); these reserves are audited.
OPEC: because quotas depend upon reserves, OPEC members report proved reserves
(1P), which is their national wish (of course non-audited).
Former Soviet Union: ABC1 (Khalimov 1979) reports maximum theoretical
recovery, being equal to proven plus probable plus possible (3P).
Rest of the world: SPE/WPC (1997) regulations report reserves as proven plus
probable (2P), close to the mean value or a probability of 50%. Oil companies use SPE 2P
reserves to decide the development of their fields, but they are obliged to report only SEC 1P
reserves!
But as he says, you have to make a guess at the ultimate if you're going to make a forecast. He's still sticking to the linearization, which really about all there is.
