Hydrology & Subsurface Flow

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...
	Buoyancy Flow with Darcy's Law: The Elder Problem Density variations can initiate flow even in a still fluid. In earth systems, density variations can arise from naturally occurring salts, subsurface temperature changes, or migrating pollution. This buoyant or density-driven flow factors...
	Open-Hole Multilateral Well Multilateral wells—those with multiple legs that branch off from a single conduit—can produce oil efficiently because the legs can tap multiple productive zones and navigate around impermeable ones. Unfortunately, drilling engineers...
	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 Darcy's law physics interface is used to model the flow in the the porous...
