Influence of skin-zone on the operation of production wells

The issues occur during the operation of pumping well due to the hydrodynamic imperfections. Herewith, formation permeability in bottomhole zone is broken. This value depends not only on the actual formation permeability, but on the state of well bottomhole correspondingly as well. A calculation methodology of operation of pumping well installation considering skin-zone in well bottomhole enabling to forecast the surveys on the improvement of pump efficiency is offered.
