Thomeer proposed a correlation for estimating permeability from three parameters of the mercury capillary pressure curve, as mentioned previously. Swanson proposed a correlation between permeability and the intersection of a 45° line with the mercury capillary pressure relationship plotted on a log-log scale. 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. 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.

Thomeer capillary pressure model

Thomeer (1960) developed a method for the analysis of mercury injection capillary pressure (MICP) data, which was used primarily within Shell (Thomeer, 1983; Smith, 1992; Hawkins et al., 1993). He observed that the data from the MICP experiment, for simple rock types, could be represented by a hyperbola when plotted on Log-Log graph paper. 2014-09-01 · Thomeer (1960) presented a mathematical model to describe capillary pressure curves using three parameters. He also proposed, graphically, a relationship between air permeability and the introduced parameters. Moreover, Kewen Li [7], investigated a number of existing capillary pressure models; Cory-1954, Thomeer-1960, Brooks and Corey-1966, Van Genuchten-1980-, Skelt and Harrison-1995, Jing and Van Wunnik-1998, and Li and Horne-2001, he prevailed that all of these capillary pressure models were proposed empirically; and almost parameters involved in these models do not A new capillary pressure model is proposed. It is based on previous study, and largely empirical. It is tested with over 200 samples covering a wide range of lithology iv (clean sandstone, shaly sandstone, and carbonates dominated by intergranular pores).

I also incorporate characteristics of capillary pressure behavior using the classic Brooks-Corey power-law model.

The new capillary-pressure model is applied to evaluate sealing capacity of seals, calculate transition zone thickness and saturation above free water level in reservoirs.

Converting Capillary Pressures to the Height Domain. 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.

For reservoir rock/fluid 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. 2017-08-20 A new capillary pressure model is proposed. It is based on previous study, and largely empirical. It is tested with over 200 samples covering a wide range of lithology iv (clean sandstone, shaly sandstone, and carbonates dominated by intergranular pores).

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.

Thomeer proposed a model of the following form for describing mercury-injection capillary pressure data: ..(3) in which S Hg is the saturation of mercury. The Thomeer function has three parameters: Threshold pressure P ct; Pore geometric factor G; Mercury saturation at infinite capillary pressure S Hg∞ The Thomeer Analysis is a method to evalute mercury injection capillary pressure (MICP) data. The resulting fitting parameters (displacement pressure, pore geometric factor, Bulk volume occupied at infinitive pressure) can be used to characterize the pore structure and to build a saturation model. For more information: A Thomeer forward-modeled capillary pressure curve can be generated from insight into the generating parameters that can come from a variety of sources of rock data, from cores to cuttings and the Shell Rock Catalog (Thomas et al., 1995).
