SEISMIC MARINE PROSPECTING METHOD USING A HYDROPHONE AND GEOPHONE SENSOR COUPLE

摘要

P Marine seismic survey method using at least one pair of hydrophone / geophone sensors located at the bottom of the water, in which a sound source on the surface of the water emits an acoustic signal and the sensors at the bottom water fall under hydrophone H and geophone G recordings, characterized by the following different steps: BR/ - a filtered signal such as BR/ (CF DRAWING IN BOPI) BR/ where HR and GR are determined correspond respectively to the H and G records propagated through a round trip in the water layer, BR/ - the data thus obtained are processed to deduce information on the geology of the subsoil. / P
