Dual Permeability Models are mathematical and computational models used to describe the flow of fluids through porous media, such as rocks and soils. These models are particularly relevant in the fields of petroleum engineering, hydrology, and environmental science. The concept of dual permeability arises from the observation that many porous media exhibit two distinct flow regimes: a fast flow through large, interconnected pores and a slower flow through smaller, less connected pores.

In dual permeability models, the porous medium is represented as two overlapping continua: a matrix and a fracture network. The matrix represents the bulk of the porous medium, while the fracture network represents the larger, more interconnected pores. Each continuum has its own permeability, which is a measure of the ease with which fluids can flow through it. The interaction between these two continua is typically modeled using transfer functions, which describe how fluids move from one continuum to the other.

Dual permeability models have been successfully applied to a wide range of problems, including the simulation of oil and gas reservoirs, the prediction of groundwater flow, and the assessment of contaminant transport in soils. They provide a more accurate representation of fluid flow in porous media than single-permeability models, which assume that all pores are equally interconnected. However, dual permeability models are also more complex and computationally intensive, requiring sophisticated numerical techniques for their solution.
