Further to this, once a field has been explored and enough known to be confident in the amount recoverable (90% certain), then that amount is declared as reserved and effectively gets added to the balance sheet using one of the ‘standard’ measures for accounting these things.
Loads of links online for that with a few seconds search, but the upshot is many companies will value it on their books based on the money they expect to make from it… no surprise because that it a bloody sensible way to value it!
If they know they can get it out by spending x capital on wells, then they roll that capex into the costs and amortise over the life of the reservoir. They can quite fairly say this many barrels, this fully coated extraction cost, this average selling price, therefore it is x value.
Our one point something billion barrels of oil, even if only 20% gets classed as reserves, is incredibly valuable on someone’s books ($billions)
