AREAL SEISMIC METHODS FOR DETERMINING THE EXTENT OF ACOUSTIC DISCONTINUITIES

The collection of areal seismic reflection data is becoming fairly routine. It is now generally realized that the solution of three-dimensional (3-D) structural problems is only possible when the target has been adequately sampled and the data have been correctly migrated to produce an accurate image of the subsurface. However, many of our exploration prospects are associated with lithological changes or stratigraphic features rather than structural features. We show how areal seismic techniques can provide an added dimension in determining the extent of acoustic discontinuities in areas where the strata are generally flat. © 1981 Society of Exploration Geophysicists.
