Abstract
A method is described for high-resolution seismic imaging of complex subsurface volumes using a two-stage least-squares reverse time migration with two objective functions. A traveltime misfit objective function enables long-wavelength imaging and an amplitude misfit objective function enables short-wavelength imaging. The method may be executed by a computer system.
