Abstract
An improved seismic method comprises the steps of generating seismic waves by exploding an explosive device in a subterranean formation, wherein the explosive device comprises a plurality of explosive elements whereby there is a time delay between the detonations of the individual explosive elements, and detecting the seismic waves and/or reflections thereof with seismic detectors. Also disclosed are geophysical survey systems that comprise a seismic energy source comprising an explosive device that comprises a plurality of explosive elements, the seismic energy source being located in a subterranean formation, and a plurality of seismic detectors that are adapted to detect seismic waves and/or reflections generated when the seismic energy source explodes.
