DETERMINING ATTRIBUTES OF SEISMIC EVENTS

摘要

A technique includes receiving seismic data, which are acquired by a seismic sensor. The seismic data are indicative of an observed wavefield quantity that is associated with a seismic event. The technique includes determining a candidate event for an observed wavefield quantity based at least in part on a ghost model, a source wavelet and a candidate value for at least one directional attribute quantity of the seismic event; correlating the candidate event with the observed wavefield quantity; and determining an event time based on the correlating.
