3537.     UREN, L. C.  Impact of Wartime Conditions on the Petroleum-Producing Industry.  Petrol. Eng., vol. 17, No. 4, 1946, p. 203, 204, 206.

        Discussion of technologic developments during the war period and their effect on the petroleum industry.  One of the most notable is the large-scale production of synthetic oil products from natural gas, coal, and shale oil.  The Fischer-Tropsch process for synthesis of hydrocarbons from CO and H₂ is particularly promising and is said to be successful in producing motor fuels from natural gas at costs competitive with present day costs of petroleum fuels.  Natural-gas reserves have assumed new significance as a result of this development.  Hydrogenation of coal also has advanced economically and technologically.
