Thomeer proposed a model of the following form for describing mercury-injection capillary pressure data: RTENOTITLE.

In this paper, we developed a novel methodology, based on Thomeer formalism and optimization techniques, for capillary pressure estimation using “standard” log data. With this methodology, capillary pressure will cover a larger volume of the reservoir than the volume covered by the SCAL. J. H. M.

In reality, capillary pressure and relative permeability effects are often coupled in a single flow experiment, and their separation requires the use of a numerical simulator (Archer and Wong, 1973; Sigmund and McCaffery, 1979 and Tao and Watson, 1984).

With the method proposed by this study, synthetic capillary pressure curves can be obtained and applied to petroleum exploration and production.

A method is presented that provides a mathematical description of capillary pressure curves and, probably, of differences in pore geometry of samples. The technique is based on the observation that the location and shape of a capillary pressure curve reflect characteristics of the pore structure of the sample.

It was found that the universal capillary pressure model could be reduced to the frequently-used Brooks-Corey capillary pressure model and the Li-Horne imbibition model when the fractal dimension of the porous media takes a limiting value.

Saturation was calculated for the reservoir The capillary pressure J-function is a dimensionless measure of the capillary pressure of a fluid in a porous medium. The function was derived based on a capillary bundle model.

The pressure gradients for the oil and water phases are determined by the fluid densities. The water saturation distribution above FWL (or below FWL for a negative capillary pressure in an oil-wet system) is controlled by the balance of capillary and buoyancy (gravity and density 2016-02-09 Current Filters. entry pressure Feature 2017-04-26 2014-03-01 tion capillary pressure data.

Rock-fabric-specific capillary pressure models were developed by Lucia (1995, 1999). New data acquired in this study compare well with the existing Class 1 model. However, new data from ARFN 2 and 3 samples do not fit previous models. We developed new models for ARFN 2 and 3 rocks using the Thomeer method.

Abstract. A method is presented that provides a mathematical description of capillary pressure curves and, probably, of differences in pore geometry of samples. The technique is based on the observation that the location and shape of a capillary pressure curve reflect characteristics of the pore structure of the sample.

Continuous capillary pressure (P c ) curves of subsurface rock formations adjacent wells are determined based on translation relaxation time (T 2 ) data from nuclear magnetic resonance (NMR) and from wireline well logs, such as resistivity logs, to obtain water saturation (S w ) of the rock in the formations.
