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.
