Zusammenfassung:	Techniques are disclosed relating to forward and inverse modeling of geophysical formations using interpolation. In one embodiment, a method includes generating a system of equations based on a background model that describes a geophysical formation. In this embodiment, the method also includes generating a first set of solutions for the system of equations using an initial set of base points from geophysical survey data obtained from the geophysical formation and interpolating, using the first set of solutions, to produce a set of solution approximations for a second set of data points from the geophysical survey data. In this embodiment, the method also includes generating a model of the geophysical formation, using the second set of data points and the set of solution approximations, where the model includes a second set of solutions for the system of equations.
