Source-receiver position estimation using direct arrival modeling and inversion

摘要

A method for correcting physical positions of seismic sensors and/or seismic sources for a seismic data acquisition system. The method includes estimating (1200) a respective energy generated by each source element, which belongs to a source array; calculating (1206) a respective energy recorded by each individual seismic sensor, which belongs to a composite receiver; summing (1210), for each individual seismic sensor, all the generated energies from the all the source elements; estimating (1212) a model of direct arrival waves that propagate from the source elements to the individual seismic sensors; calculating (1212) positions of the individual seismic sensors based on the model of direct arrival waves; comparing (1216) calculated positions of the individual seismic sensors with observed positions of the individual seismic sensors; selecting (1218) a best calculated position for each of the individual seismic sensors based on an objective function; and correcting (1224) the observed positions of the individual seismic sensors with corresponding best calculated positions.
