WERKWIJZE VOOR DRIE-DIMENSIONAAL SEISMISCH ONDERZOEK.

摘要

An improved method for three-dimensional seismic exploration of the subterranean structure of the earth is disclosed wherein arrays of sources of acoustic energy and of detectors of reflected energy are used. The configurations of both arrays are conjointly experimented with to improve the signal-to-noise ratio of the resultant data; the signals output by the detectors are summed, and are correlated with those output with respect to all acoustic energy emitted within a given array of sources.
