The article formulated and investigated the problem of finding a horizontal non-component field of stresses and effective viscosity according to the caliper data in a well held in a rock with rheological properties use visco-elasticmodel. According to the data of numerical studies using artificial input data, the range of variation of the effective viscosity and the necessary time for the experiment are established so that the inverse problem has the only solution.
