The Effects of Scattering on Seismic Wave Pulses

This paper presents a detailed study of the scattering effect of a single, sand-lens like, obstacle embedded in a uniform medium. The problem is first considered theoretically using the first order perturbation technique previously developed by the author and this theory is then used to compute scattered pulse forms for different receiver positions and obstacle shapes. These pulse forms are subsequently compared with results from two-dimensional seismic modelling experiments. This comparison shows the utility of this theory as an aid in improving seismic interpretation in the presence of scatterers.
