WebPermeability is a measure of the degree to which the pore spaces are interconnected, and the size of the interconnections. Low porosity usually results in low permeability, but high porosity does not necessarily imply high permeability. It is possible to have a highly porous rock with little or no interconnections between pores. Web29. jan 2024 · Geologic structure plays an important role in controlling fluid flow in geothermal systems.

Web29. sep 2014 · Permeability is a measure of the ability of a fluid to pass through its porous medium. Permeability is one of important to determine the effective reservoir. Porosity and permeability are two properties describing the reservoir rock capacity with regard to the fluid continence. Moreover, a reservoir rock can be porous without being permeable. WebPermeability and Seepage - N. Sivakugan (2005) 1 Chapter 7 Permeability and Seepage 7.1 INTRODUCTION Permeability, as the name implies (ability to permeate), is a measure of how easily a fluid can flow through a porous medium. In geotechnical engineering, the porous medium is soils and the fluid is water at ambient temperature.
