Frasier, C W

A method is described of improving resolution of seismic data collected by conventional common midpoint collection (CMP) methods including sequentially activating a conventional seismic source at a series of sourcepoint locations (SP) along a line of survey and redundantly collecting reflection of both the conventional waves and the converted phases thereof via a series of multicomponent detectors at a plurality of detector stations (D) along the line of survey each detector simultaneously but separately recording the motion of the earth in the radial horizontal direction and in the vertical direction. Each resulting convention and converted trace is associated with a sourcepoint-detector station pair of known (SP,D) coordinates, the improvement thereof related to processing both conventional and converted traces in a systematic manner whereby resulting conventional and converted gathers of such traces each samples a reflection point of a target reflector in the subsurface common to each gather irrespective of dip and depth of the target reflector.
