A Study of Klinkenberg Effect on Molecular Slip in a Heterogeneous Porous Medium
Abstract/Contents
- Abstract
- Analysis of field cores is an important method of obtaining reservoir properties such as permeability. The permeability can vary with the orientation of the fluid flow with respect to the porous medium.The directional permeability measurements were performed using a spherical porous test sample shaped from a Berea Sandstone core. By introducing compressed nitrogen into the center of the sphere, and measuring both the flow rate at a specific location on the sphere's surface and the pressure differential, the permeabilities to a gas were found.Due to the low mean pressure in the flow system Klinkenberg moleculer slip accounted for a significant permeability increase, as theory would predict. By using the Klinkenberg slip factor, the absolute permeabilities were obtained at several locations. The temperature of the nitrogen was kept constant so that the Klinkenberg slip factor could be used with the permeability to determine the heterogeneous and isotropic properties of the sandstone core.
