WebPermeability, 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. Generally, coarser the soil grains, larger the voids and larger the permeability. WebFeb 26, 2024 · There are many applications for hydraulic fracturing. Hydraulic fracturing can: Increase the flow rate of oil and/or gas from low-permeability reservoirs. Increase the flow rate of oil and/or gas from wells that have been damaged. Connect the natural fractures and/or cleats in a formation to the wellbore.
