WebAbstract. An investigation has been made of the relations among porosity, permeability, and texture of artificially mixed and packed sand, to determine the approximate porosity and … Webments with water flowing through sand. These experiments led to the for-mulation of Darcy’s law, which describes the steady-state flow of fluid through porous media. In most oilfield applications, the common unit is the millidarcy (mD) [about 10−15 m2]. Permeability is not to be confused with mobility or with hydraulic con-ductivity.
