Methods of geophysical exploration
This patent describes a method of seismic exploration. It comprises imparting seismic energy into the earth's subsurface at selected intervals along a generally linear shot line; recording a plurality of seismic signals representative of the earth's response thereto at selected intervals along a generally zigzag receiver line for a plurality of source-receiver pair azimuths; sorting the seismic signals into common mid-point (CMP) bins to obtain CMP bins of seismic signals having a plurality of source- receiver azimuths effective for three-dimensional (3-D) processing; and 3-D moveout correcting the seismic signals in each CMP bin employing a three parameter moveout correction, wherein the three parameters include velocity, dip, and the azimuthal orientation of dip.
