Method of seismic prospecting with very high resolution in horizontal boreholes

摘要

A method of seismic prospecting with very high resolution as applicable in particular to exploitation of a productive hydrocarbon deposit essentially consists in transmitting and receiving acoustic waves, in recording shot moments, in determining average propagation velocities of refracted and reflected waves and in establishing a depth-section in order to determine the positions of interfaces located within the geological zone traversed horizontally by a horizontal borehole.
