Failure of a Multilateral Well

Multilateral wells—those with multiple legs that branch off from a single well—can produce oil efficiently because the legs can tap multiple productive zones and navigate around impermeable ones. Unfortunately, drilling engineers must often mechanically stabilize multilateral wells with a liner or casing, which can cost millions of dollars. Leaving the wellbore uncased reduces construction ...

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 porous block The fracture flow is modeled by adding the Fracture Flow feature to the Darcy's law interface. The fracture flow is added to a 2D surface in the 3D domain. This model ...

Variably Saturated Flow

This example utilizes the Richards’ Equation interface to assess how well geophysical irrigation sensors see the true level of fluid saturation in variably saturated soils. The challenge to characterizing fluid movement in variably saturated porous media lies primarily in the need to describe how the capacity to transmit and store fluids changes as fluids enter and fill the pore space. ...

Terzaghi Compaction

Fluids that move through pore spaces in an aquifer or reservoir can shield the porous medium from stress because they bear part of the load from, for instance, overlying rocks, sediments, fluids, and buildings. Withdrawing fluids from the pore space increases the stress the solids bear, sometimes to the degree that the reservoir measurably compacts. The reduction in the pore space loops back and ...

Aquifer Characterization

This model uses the Optimization interface to solve the inverse problem for determining the spatially variable hydraulic conductivity on a discretized quadratic grid from a number of aquifer pump tests. Because the number of observations is smaller than the number of unknown parameters, a geostatistical penalty term is used to discriminate between solutions with comparable fitness values. ...
