About method of the least squares implementation to problem of non-isothermal filtration

Parameters identification for petroleum stratum by the method of least squares is considered. The method consists in following: a direct problem is solving for considered equation system under appropriate initial and border conditions. Then an inverse problem is solving for receiving of approximated values coefficients of equation. In this case got values are comparing with factual data from history of the petroleum disposal operating. The method is one of effective ways at solution of similar problem on modern personal computer
