Modeling and Simulation of the Wafer Non-Darcy Flow Experiments

SPE Western Regional Meeting, 2001
Abstract Darcy's law governs most flow patterns in petroleum recovery processes. However, when fluid flow velocity is very high, for example, near the wellbore, Darcy's law may be inadequate to simulate the fluid flow. The non-Darcy effect has been incorporated into the Department of Energy (DOE) reservoir simulator MASTER

NON-DARCY FLOW THROUGH LARGE GRANULAR MEDIA

ISH Journal of Hydraulic Engineering, 1998
ABSTRACT This paper presents the results of applying dimensional analysis to obtain a relationship between friction factor and Reynolds number for flows through porous media using a directly measurable parameter such as hydraulic radius R, which is equal to void ratio e divided by the specific surface So, as characteristic length.

Investigation of Non-Darcy Flow for Fine Grained Materials

Geotechnical and Geological Engineering, 2018
Research efforts have been done to determine the limit of validity of Darcy’s Law in various fields of engineering where viscous conditions of flow are likely exceeded. In geotechnical and geological engineering, the application of centrifuge modeling for studying flow through porous materials is complex because the seepage velocity scales ...

Non-Darcy Flow Near Hydraulically Fractured Wells

SPE Journal, 2004
Summary In this work, we analyze the effect of non-Darcy flow near hydraulically fractured wells on well inflow performance. It is based on a dedicated numerical model of plane, steady-state flow of an incompressible fluid toward a vertically fractured well in the center of a circular reservoir.

Non-Darcy flow behavior in liquid-saturated porous media

Journal of Geophysical Research, 1962
Velocity-gradient data for water-saturated porous media were considered in some detail. Deviations from Darcy's law were found in data originally presented in support of the law. Recent data were analyzed on the basis of a postulated three-parameter equation, in contrast with the one-parameter Darcy proportionality. The equation contains Darcy's law as

Volumetric approach to non-Darcy flow in confined aquifers

Journal of Hydrology, 1986
Abstract Analytical expressions for type curves are derived for non-Darcian groundwater flows which occur naturally in coarse grained or fractured media. The basis of the derivation is the continuity equation coupled with the Forchheimer flow law which has laminar and turbulent flow components.

Non-Darcy flow through synthetic porous media and development of non-Darcy coefficient correlations

The flow in porosity is one of the hot research topics involved in many engineering applications, so there has been extensive research in this field. The flow in porous media is either Darcy or non-Darcy, depending on the flow velocities. Therefore, the need for a study that effectively: presents an experimental study that captures the complexity of ...
