Thus the absolute or total porosity = effective porosity + ineffective porosity Interconnected and connected pores constitute effective porosity because hydrocarbons can move out from them.
Web12 sep. 2024 · Ineffective porosity (also called closed porosity) Refers to the fraction of the total volume in which fluids or gases are present but in which fluid flow can not effectively take place and includes the closed pores. Understanding the morphology of the porosity is thus very important for groundwater and petroleum flow. Web25 jun. 2015 · Porosity decreases until high pore pressures (= geopressure) reduce the effective pressure and cause an increase in porosity (from Stuart [9] ). Measurement techniques Laboratory Numerous methods can be used in the laboratory to determine porosity and density. The most common are by saturation weight and Boyle’s law.
WebCOMSOL Multiphysics software was used in conjunction with MATLAB to create the computational models necessary for this study. Computational models were built using the porous media flow (PMF) module to simulate the sponge-like characteristics of the lung tissue in the presence of edema fluid [6]. Validation of the model, performed in ...
