Effective porosity of sand
WebEffective porosity (also called open porosity) Refers to the fraction of the total volume in which fluid flow is effectively taking place and includes catenary and dead-end (as these … WebEffective porosity is defined as the total porosity minus the clay bound water (blue area only). Further adjustments are sometimes made to generate useful or connected porosity, which excludes clay bound water and any unconnected pores, such as pin-point vugs or isolated pores inside the sand grains.
