Simultaneous vertical-seismic profiling and surface seismic acquisition method
This patent describes a method of seismic exploration. It comprises: deploying at least one sensor in a borehole located at a predetermined depth; towing a seismic streamer cable behind a vessel steering a partial circle of predetermined radius and having an orbital focus located substantially above the borehole; generating seismic signals from a source associated with the vessel; receiving reflected seismic signals from the source at the at least one sensor located in the borehole while simultaneously receiving reflected seismic signals at the streamer cable. The at least one sensor and the streamer cable providing an output indicative of the received seismic signals; and correlating the output indicative of the received seismic signals from a reflected subsurface horizon common to the at least one sensor and the streamer cable.
