Abstract
GPU has been performed in PSTM and RTM for years, and now further applied to multiple attenuation of marine data processing. Surface-related multiple elimination (SRME) algorithm can predict multiples but be burdened by strict requirement on data, we exploit the combination of DMO and DMO-1 method to reconstruct data to regular grid. The common offset gathers are utilized instead of common-source gathers and common-receiver gathers for GPU application. With the aid of GPU, the algorithm can get excellent results effectively.
