Permeability of rocks
Webpermeability of rocks and soils or the effective hydraulic aperture of fractures in situ on outcrops as well as on laboratory specimens [6]. The apparatus is capable of making permeability measurements ranging from 0.01 to 10 darcies for matrices and 10 μm to 2 mm fracture apertures [6]. WebApr 22, 2024 · Permeability is a measure of a rocks ability to transmit fluids. In addition to being porous, a reservoir rock must allow fluids to flow through its pore network at practical rates under reasonable pressure differentials. Controls on permeability include: • The size of the available pores.
