Permeability parameter

WebPermeability is one of the important parameters for reservoir evaluation, development, and production prediction. Shale oil and gas being an important unconventional energy source, the characteristics of extremely low porosity and permeability bring great challenges to … Let be oil relative permeability, and let be water relative permeability. There are two ways of scaling phase permeability (i.e. effective permeability of the phase). If we scale phase permeability w.r.t. absolute water permeability (i.e. ), we get an endpoint parameter for both oil and water relative permeability. If we scale phase permeability w.r.t. oil permeability with irreducible water saturation present, endpoint is one, and we are left with only the endpoint parameter. In order to satisfy bot…

Web22. mar 2013 · Permeability is an important parameter to characterize the ease with which a porous medium transmits fluids, and an accurate measurement or estimation of permeability has been a challenging task, especially for media with low permeability. Web5. apr 2024 · We present a mathematical model for carbon dioxide generation rate during fermentation using the onggi’s gas permeability as a free parameter. Our model provides a good fit for the data, and we conclude that porous walls help the onggi to ‘exhale’ carbon dioxide, lowering internal levels to those favoured by lactic acid bacteria.
