Identification of mobilities for the Buckley-Leverett equation

The authors consider a method for determining mobilities by optimal control. The method developed permits one to use an arbitrary number of free parameters in the mobilities and three free parameters in the fractional flow function. This approach covers all previous approaches that deal with optimal control. Computed examples confirm a theoretical expectation that the pressure response can be fitted to any precision and the recovery response with a small error. They give a detailed theoretical study and a comparison with previous approaches.
