ABSTRACT:
A system and method for pre-stack imaging system that includes multiple processors, with each processor configured to perform two-way wave equation-based forward wave propagation of a source event to obtain a source wave field using high order spatial finite differences for a shot gather, and to perform two-way wave equation-based backward wave propagation of received waves to obtain a receiver wave field using high order spatial finite differences for the shot gather; and to correlate the source and receiver wave fields to obtain an image region.
