Capillary pressure can serve as both an opposing or driving force for fluid transport and is a significant property for research and industrial purposes (namely microfluidic design and oil extraction from porous rock). It is also observed in natural phenomena. See more In fluid statics, capillary pressure ($${\displaystyle {p_{c}}}$$) is the pressure between two immiscible fluids in a thin tube (see capillary action), resulting from the interactions of forces between the fluids and solid walls of … See more Capillary pressure formulas are derived from the pressure relationship between two fluid phases in a capillary tube in equilibrium, which is that force up = force down. These forces are described as: These forces can … See more Needle ice In addition to being manipulated for medical and energy applications, capillary pressure is the cause behind various natural phenomena … See more • Capillary action • Capillary number • Disjoining pressure • Leverett J-function • Young–Laplace equation See more Capillary pressure is defined as: $${\displaystyle p_{c}=p_{\text{non-wetting phase}}-p_{\text{wetting phase}}}$$ where: See more Microfluidics Microfluidics is the study and design of the control or transport of small volumes of fluid flow through porous material or narrow channels for … See more It has been shown that as reservoir simulators use the primary drainage capillary pressure data for saturation-height modeling calculations, primary drainage capillary pressure data should be averaged in the same manner that water saturations are … See more WebJan 19, 2016 · After completing measurements of capillary pressure for primary drainage, the direction of saturation change can be reversed, and another capillary pressure …

How to plot centrifuge capillary pressure vs corrected saturation?
WebThe capillary pressure curve consists of three branches: a primary drainage, a primary imbibition and a second drainage branch. Below we will discuss these branches in some detail. 1st-Drainage At Sw=1, the start of the 1st drainage, an "entrance" pressure needs to be exceeded before oil can enter the sample. Then a plateau is reached. WebJan 19, 2016 · After completing measurements of capillary pressure for primary drainage, the direction of saturation change can be reversed, and another capillary pressure relationship can be measured—it is usually called an imbibition relationship. Imbibition is often analogous to the waterflooding process. WebOct 29, 2008 · The first term is the forced part of the capillary pressure with LET function fp. cow. F. The ...
