Figure 12. Estimates as of January 1994 of proved crude oil reserves, projected crude oil reserve additions through 2015 for oil fields discovered before 1992, and the combined estimates of crude oil in undiscovered conventional oil fields and from continuous-type oil accumulations having incremental costs of $30 per barrel. Quantity of crude oil is in billions of barrels.

Figure 13. Estimates as of January 1994 of proved non-associated gas reserves, projected non-associated gas reserve additions through 2015 for gas fields discovered before 1992, and the combined estimates of non-associated gas in undiscovered conventional gas fields and from continuous-type gas accumulations having incremental costs of $3.34 per thousand cubic feet. Quantities of gas are in trillions of cubic feet and do not include natural gas liquids.
