Abstract
A method of correlating seismic events associated with different types of seismic transmission modes and includes calculating a shift estimate between a first set of seismic events or attributes associated with the seismic events attributable to one type of transmission mode and a second set of seismic events or attributes associated with the seismic events attributable to a different type of transmission mode using a smoothed version of at least one of the sets of seismic events or attributes associated with the seismic events, and updating the shift estimate using a less severely smoothed or unsmoothed version of the at least one set of seismic events or attributes associated with the seismic events. A related computer system and computer program products associated with the method are also described.
