Abstract
The present invention provides improved methods for processing seismic data which include the effects of offset dependence of reflection amplitudes. The methods of the present invention provide a way to estimate and remove the effect of stretch and small moveout velocity errors on the measurement of offset dependence for the case of small offsets (less than about 30 degrees angle of reflection). Further, the methods of the present invention provide an improved estimate of the correct movement velocity.
