Hence, when it comes to building reservoir models and estimating volumes in-place, capillary pressure based saturation-height models are used to de- scribe Sw. For unconventional reservoirs, even if capillary pressures are not controlling Sw, saturation-height modelling provides a means to describe Sw variations in reservoirs using property variations.

Using (Fg) derived from Wu (2004) method, the relation is improved considerably and recorded the highest correlation among the used models (Table 3). The porosity can be used instead of the fractional bulk volume occupied by Summary Reservoir engineers use capillary pressure to compute the original hydrocarbon in place and to estimate the ultimate recovery using fluid flow simulation. Traditionally, capillary pressure data are obtained from the special core analysis (SCAL). SCAL is a time consuming and expensive procedure.

There are four common functions available within the SHM module: Brooks-Corey, Lambda, Thomeer, and Leverett-J function. Each functional solution has three coefficients. Converting Capillary Pressures to the Height Domain.

An analytical model for predicting the capillary pressure-saturation profile developed across the interface that separates two immiscible fluids has been derived from reservoir pressure transient analysis.

Michael (Friendswood, TX), Thomeer; Bart (Houston, TX), Bissonnette;  Thomeer model. 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.

This pressure results from the contrast in pressure gradients caused by the different densities of the nonwetting ( ρ nw ) and wetting ( ρ w ) phases (right). Capillary pressure is a critical property for reservoir modeling. Reservoir engineers use capillary pressure to compute the original hydrocarbon in place and to estimate the ultimate recovery using fluid flow simulation. Traditionally, capillary pressure data are obtained from special core analysis (SCAL). 2016-01-19 The Thomeer Analysis is a method to evalute mercury injection capillary pressure (MICP) data.

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. 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.

A set of sixty four Mercury Injection Capillary Pressure curves from a Middle East tight carbonate reservoir were modelled with Thomeer hyperboles and grouped using K-medoids clustering. 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. 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.

The breakthrough pressures (Pb) and Thomeer shape factors (C) are defined for each capillary pressure curve We did this using data up to 1000psi mercury capillary pressure because this equates to the maximum reservoir thickness i.e. 200m Thomeer Model in a Tight Gas Reservoir

This also demonstrates that the Brooks-Corey model and the New Mexico Institute of Mining and Technology of mercury capillary curves using the Thomeer-method. Since the widely used sured data needed for a valid drainage capillary pressure curve represents the be able to model initial water saturation the Pcl needs to be converted to 12 Apr 2018 Theoretical background of Thomeer hyperbola rock typing.
