Abstract
The present invention provides a method of determining source and receiver static corrections for seismic data that does not depend on user supplied velocity parameters or input models. The method comprises decomposing first break seismic data arrivals into source id terms, receiver id terms, offset terms and average datum correction terms. The source id terms and receiver id terms and offset terms are applied to the seismic data to obtain residual first break times. Average datum correction terms are determined by forming a nonlinear equation for a least-squares fit of the residual first break times as a function of elevation difference. At least one receiver static correction term is determined from the receiver id terms and receiver average datum correction terms. At least one source static correction is determined from said source id terms and source average datum correction terms.
