Integrating Inertial Factor Obtained From Turbulent Gas Flow in Reservoir Characterization and Well Performance

Abstract

Darcy's law applies only in the region of streamline flow, however when it concerns inertial or turbulent flow regime such as large production or injection rate in the vicinity of the wellbore, the turbulence effects affect considerably the cinematic charges and production rate due to the fact that the pressure gradient increases at a greater rate than does the flow rate. Forchheimer's publication in 1901 is commonly marked as the start of a general understanding that Darcy's law is not universally valid for porous flow. Since then non-Darcy flow has been in continuous investigation.
