Abstract

Diffusion forces have been ignored when modeling fluid flow in porous media with a consent belief that viscous transport is the predominant controller. This work introduces a new comprehensive flow model suitable for tight UCRs including viscous, inertia and diffusion forces to account for the transport of fluid in the three scales. A new model addressing multiphase 1-D radial flow in tight UCRs has been mathematically derived and numerically solved, tested and verified against real cases using MATLAB software. A detailed parametric analysis and verification has been carried out and a very clear profiles and flow patterns of the main flow parameters were identified. It has been established that, with lower permeability of the porous medium and lower viscosity of the flowing fluid, the diffusion mechanism becomes more predominant in controlling flow velocity. The results of the newly derived equations that includes the diffusion term have significantly shown the contribution of diffusivity to the flow in the nanoscaled pore spaces as suspected and proven by the numerical models created and the comparison between the suggested equation to other equations and correlations that are used in the field to describe the behavior of the flow in low permeability and low porous medium was established.
