Inverse problems of elastoplastic filtration of liquid in a porous medium

Inverse coefficient problems for equations of elastoplastic filtration of fluids in a porous medium in the regime of reduction and recovery of pressure have been solved by applying the methods of identification of parameters and deterministic moments. Examples of determining the piezoconductivities of a bed in the regimes of reduction and recovery of pressure in a well are given, where the values of the solution of the corresponding direct problem determined at the given points of the bed are used as the initial information.[PUBLICATION ABSTRACT]
