Simultaneous acquisition during both acquisition and seismic inversion seismic

摘要

1 / 1 Summary "simultaneous acquisition during both acquisition and inversion of seismic seismic method to acquire, at reduced cost of acquisition.Seismic data empregandose simultaneous acquisition coded in field in the field (702) and then building - wannabe records of source (703).To better meet the requirements to use purchase coded by simultaneous computer further, for computer simulation or modeling directly (706).As part of the (707) FWI (reversal of the field full wave) iteratively or RTM (migration time reverse), with further reduction of computational costs.Better satisfying the demands of simultaneous acquisition FWI or RTM (701), the artifacts and cross talk are reduced at the exit.The method can be used for the acquisition of streamer marine and other geometries of length is not fixed.To acquire the displacements both positive and negative, and to mitigate the problem of "missing data" FWI source simultaneously.It can also be used for terrestrial data to overcome problems with mobile extensions and long continuous records.
