... Joint surface and borehole seismic are a 3D surface-and-borehole seismic exploration method of the simultaneous acquisition of onshore or offshore 3D seismic and VSP (Vertical Seismic Profile) data using the same sources. When acquiring surface 2D or 3D seismic data in the field, simultaneously...
