Abstract
A method for spatially interpolating pressure values of seismic data uses known values of pressure and spatial derivatives of pressure at a plurality of irregularly spaced locations along the direction of interpolation. The interpolation preferably uses an interpolation operator calculated by assuming that an interpolated pressure value comprises a linear combination of the known pressure values at locations xand the spatial derivatives at locations X, with operator coefficients wand wrespectively, and calculating the coefficients by minimizing an error function.
