EPSI is a seismic free-surface removal technique proposed by van Groenestijn and Verschuur (2009) as an alternative to the traditional adaptive-subtraction process that currently underlies the overwhelming majority of multiple elimination processes. Its theoretical pedigree stems from the familiar relation between the primary and multiple parts of the recorded wavefield that underlies Surface-Related Multiple Elimination (SRME). See
