Abstract
The invention comprises the generation of seismic signals at a survey site at which seismic sensors are deployed by dropping mass units from an overflying aircraft. The mass units will impact the earth's surface at said survey site to generate seismic signals. The seismic sensors are utilized to detect the resulting seismic signals.
Claims30
A method for performing seismic exploration comprising:
- deploying a plurality of seismic sensors on the earth's surface at a seismic survey site;
- dropping a mass from an aircraft while said aircraft is at an elevation above said seismic survey site of greater than about 500 feet, thereby generating a seismic signal from impact of said mass on the earth's surface at said seismic survey site;
- detecting seismic signals with said plurality of seismic sensors resulting from said impact of said mass on the earth's surface;
- and
- applying a triangulation method to the seismic signals detected by at least three of said sensors to determine the location of the impact of said mass on the earth's surface.

A method for performing seismic exploration, comprising:
- deploying a plurality of seismic sensors on the earth's surface at a seismic survey site;
- dropping a mass from an aircraft onto said seismic survey site, thereby generating a seismic signal from the impact of the mass on the earth's surface, said mass having an electromagnetic signal generator attached to said mass;
- transmitting an electromagnetic signal from said electromagnetic signal generator attached to said mass to indicate the time of impact of said mass on the earth's surface;
- detecting seismic signals with said seismic sensors generated by the impact of said mass on the earth's surface;
- and
- detecting said electromagnetic signal and utilizing said electromagnetic signal to determine the time of impact of said mass on the earth's surface.
