Abstract
Method for estimating porosity and water saturation or other geological parameters of a subsurface region when the lithology of the region is unknown, requiring only geophysical data from remote surveys. The geophysical data are inverted (-) treating lithology as a third, and discrete, unknown model parameter () to be solved for in the inversion. A technique for solving mixed integer non-linear programs may be used. Suitable rock physics relationships () are used to relate the desired geological parameters to the geophysical model parameters required for simulating the geophysical data in the inversion process.
