Example Models

	Perforated Well Analysis of fluid flow into wells often begins with the assumption that the intake fluid is uniform along the entire length of wellbore. This assumption runs into trouble when applied to the modeling of perforated wells. When these wells...
	Buoyant Darcy Flow: The Elder Problem This model of buoyancy flow driven by salt concentrations is a benchmark problem originally posed for heat flow by Elder (1967) and recast for solute transport by Voss and Souza (1987). It has been used to benchmark numerous density flow...
	Failure of a Multilateral Well An increasingly common technique to maximize oil production from deep wellbores is to emplace "open" multilateral wells, with multiple legs that branch off of a single conduit. The down side of leaving the well open is a high risk of...
	Discrete Fracture This example models free flow through a fracture in a block of porous media, where flow in the fracture is much faster than in the matrix block. The approach uses internal borders for modeling the free flow in 2D. The porous media flow is...
