The Inverse Coefficient Problem for Equations of Three-Phase Flow in Porous Medium

The identification task of the absolute permeability is considered under conditions isothermal three-phase flow in porous medium. The identification process is carried out by known values of the flow rate on a single well. The resulting permeability field is used to calculate the flow rate at the fo...

Zusammenfassung:	The identification task of the absolute permeability is considered under conditions isothermal three-phase flow in porous medium. The identification process is carried out by known values of the flow rate on a single well. The resulting permeability field is used to calculate the flow rate at the following moments of time. The proposed approach is tested to solve the model problem. The influence of time and number of the flow rate measurements on the identification results is investigated.
