Abstract

An historical outline of the development of the gravity method of prospecting is presented. While the very early gravity work with pendulum equipment was for geodetic purposes alone, the increased instrumental sensitivity made available with the development of the torsion balance by Eoetvoes (1888), led in 1915, to the first gravimetric survey for oil prospecting in the Egbell field, Czechoslovakia. The application of the method to prospecting in the United States started in 1924 with the discovery of the Nash dome in Coastal Texas by a torsion balance survey. The development and use of improved pendulum equipment is discussed and finally the recent marked increase in gravity work resulting from the introduction of the gravimeter about 1930 to 1935.
