dc.descriptionThis study adds a new dimension to fluid flow in porous media by replacing Darcy's equation with new models that are capable of representing both Darcy and non-Darcy flow behaviors. A new diffusivity equation based on the Forchheimer's equation has been derived to replace the diffusivity equation based on Darcy's law. A new diffusivity equation has been proposed also. This model includes the viscous term presented by Darcy's equation, the inertial term in Forchheimer's equation and the frictional/viscous term of the Brinkman's equation. Finally, a new comprehensive model has been introduced. This model derived from the Navier-Stokes equation, has another connective term while collectively including all the previous terms described by other models. Mathematical derivations and numerical simulation of all suggested models are presented in this study.en_US
dc.descriptionThe evaluation of the non-Darcy coefficient, beta, from the existing correlations presented in the literature has been proven misleading; therefore, a new reliable experimental approach has been suggested as an alternative. The suggested technique gives accurate beta estimate. A new dimensionless quantity "Be" has been proposed to distinguish between Darcian and non-Darcian behaviors, "Be" found to be equal to 0.0526 at 5% deviation from the Darcian linear trend. This dimensionless group was found superior to other similar numbers proposed by previous authors.en_US
dc.descriptionIn order to correctly predict fluid flow in porous media, a coupled fluid flow/stress model has been suggested to define the relationship between porosity and mean effective stress during a depletion process. The proposed model is designed to work with fluid flow models presented herein to update the values of both porosity and permeability during the course of production from reservoirs.en_US
dc.descriptionThe proposed models and techniques presented in this study are expected to be easily applied to oil and gas reservoirs as well as in other underground fluid flow applications ensuring more accurate flow behavior predictions. (Abstract shortened by UMI.)en_US
