Method of Additional Seepage Resistances—Theory and Application

The method for additional seepage resistance based on the local consideration of zones of sharp flow deformation caused by partially penetrating boundaries is described. The allowance for the replacements of the additional resistance by an equivalent resistance to a horizontal flow through an extra length has the advantage of simplifying the subsequent calculating procedure. The application is given for the flow into open partially penetrating channels, to multiple well systems of complete or partial penetration, and to a single well of partial penetration.
