Development of Semi-Empirical Concept of Permeability: Darcy

Another derivation of Darcy's law is used extensively in petroleum engineering to determine the flow through permeable media — the most simple of which is for a one-dimensional, homogeneous rock formation with a single fluid phase and constant fluid viscosity. Almost all oil reservoirs have a water zone below the oil leg, and some have also a gas cap above the oil leg. When the reservoir pressure drops due to oil production, water flows into the oil zon… WebThis paper introduces a novel fluid transport law in porous media that can be used in oil and gas reservoir, as well as in civil, chemical, mechanical, and mineral engineering cases. … northgate telus
