Abstract The threshold pressure gradient, which is associated with non-Darcy flow in low permeability tight gas formation, is defined as the level of pressure gradient that has to be attained to enable the fluid to overcome the viscous forces and start to flow.

Numerical Modeling of Low Permeability Oil Flow with the Threshold Pressure Gradient
SPE Western Regional MeetingAbstract In this article, the authors present partial differential equation models for linear transient oil flow that include a threshold pressure gradient (TPG) assumption for low permeability flow. Results of numerical simulations developed for the dimensionless PDEs are compared to a conventional model and to each other to determine ...
