Abstract

We present the theory and numerical results for interferometrically extrapolating ocean bottom seismic (OBS) and surface seismic profile (SSP) data. This method employs a natural Green's function (i.e. shot gather) and a model-based Green's function. Numerical results show that the OBS and SSP receiver apertures can be more than doubled in width by applying interferometric extrapolation to seismic data. Results also suggest that an OBS or marine SSP survey can yield much more information about the reflectors if data are extrapolated by interferometry. This assumes that the sources are located both outside and inside the recording aperture.
