Abstract
A model problem of the permeability field identification for a three-dimensional reservoir opened by a large number of wells in the conditions of stationary singlephase fluid filtration is considered. The permeability field is determined in the process of solving the inverse coefficient problem by on known values of bottomhole pressure. The solving problem algorithm is constructed so that the proportionality coefficients of the layers permeability on wells obtained from the results of geophysical well survey are preserved. The influence of various types of errors on the identification results is studied.
