Determination of Filtration Properties of a Deformable Porous-Fractured Bed from the Results of Hydrodynamic Investigations of Horizontal Wells

Abstract

© 2014, Springer Science+Business Media New York. A computational algorithm has been proposed for interpretation of results of hydrodynamic investigations of horizontal wells in unsteady regimes of filtration in deformable porous-fractured beds. The proposed approach makes it possible to evaluate the dependence of the permeability coefficient of fractures on pressure. A study has been made of the dynamics of change in the bottom-hole pressure after bringing a horizontal well into production and shutting it down in the nonlinear elastic regime of filtration of the fluid in a porous-fractured bed.
