Characterization of a Non-Darcy Flow and Development of New Correlation of NON-Darcy Coefficient

Darcy’s law has long been used to describe the flow in porous media. Despite progress that took place oil production industry research, it became clear there is a loss of pressure, especially area near wellbore region, where not applicable. For this reason, Forchheimer presented his equation 1910, he added new term dealing with pressure due inertial forces by introducing term, β coefficient, into equation. This paper presents study fluid through media, water was as working fluid. Furthermore, characteristics non-Darcy were analyzed presenting corresponding and velocity gradient curves for each pressure. Extensive analysis indicates many correlations available literature either have defective units or are product small number experiments. In study, we benefit from relatively large samples, radial flow, perforation middle samples. The properties samples measured using mercury intrusion porosimetry. It found direct relationship between porosity grain’s size; greater size grains, porosity, vice versa. coefficient β, be inversely proportional permeability. previous investigated compressible scenarios; however, calculated an incompressible flow. Finally, analyzing values both studies, could deduce novelty permeability, tortuosity included.
