The oil industry throughout the world last year invested about $325,000,000 in geophysical exploration for oil. This marks a phenomenal growth of the science since its inception less than three decades ago. The commercial acceptance of geophysics is justified by its success in eliminating many wasteful “dry holes” in drilling for oil. Applications in the search for other minerals show encouraging gains. The paper (1) reviews briefly the history and growth of geophysical exploration, especially as related to oil-finding, and of the Society of Exploration Geophysicists; (2) discusses the present technical status and world-wide industrial scope; and (3) attempts to peer into the future to catch a glimpse of future developments and prospects.
