Stanford Exploration Project

From Wikipedia, the free encyclopedia

The Stanford Exploration Project (SEP) is an industry-funded academic consortium within the Geophysics Department at Stanford University, Stanford, CA, U.S.A. SEP research has contributed greatly to improving the theory and practice of constructing 3-D and 4-D images of the earth from seismic echo soundings (see: Reflection seismology). The consortium was started in 1970's by Jon Claerbout and is currently co-directed with Biondo Biondi.

SEP pioneered innovations in migration imaging, velocity estimation, dip moveout and slant stack. SEP has recently been involved in 3-D seismic applications such as velocity estimation, wavefield-continuation prestack migration, multidimensional image estimation, and 4-D (time-lapse) reservoir monitoring.
