STATIC CORRECTIONS FOR SEISMIC TRACES BY CROSS-CORRELATION METHOD

摘要

A method is disclosed for determining source-to-datum corrections for a multitrace seismic cross-section. The method comprises the measurement of a multiplicity of cross-correlation functions between selected traces of the seismic section to establish a redundant set of simultaneous equations including the desired source-to-datum and geophone-to-datum quantities. The simultaneous equations are then solved for the desired corrections by the least squares error method. The method of the invention also provides for the determination of residual normal moveout corrections.
