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. 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. However, the 2014-09-01 · Thomeer (1960) presented a mathematical model to describe capillary pressure curves using three parameters.

With the method proposed by this study, synthetic capillary pressure curves can be obtained and applied to petroleum exploration and production. Our model is based on Thomeer’s (1960, 1983) model: S b S b1 ¼ e Fg=ðlog Pc=PdÞ (1) k ¼ 3:8068Fg 1:3334ð100S b1=P dÞ 2:0 (2) Where k is air permeability in millidarcy, S The primary motivation for my work is to “close the loop” on relating mercury injection capillary pressure data and the simplified “bundle of tubes” permeability power law model by Brook and Corey, and is extended to incorporate the permeability model proposed by Huet-Blsingame [3] using the theory of Purcell [4] and Burdine [5], combined with the function fitting parameters of Brooks Home; CAPILLARY PRESSURE MODEL PREDICTS DISTANCE TO GAS/WATER, OIL/WATER CONTACT.

The MICP study demonstrates that the pore volume of the micropores (~25% of pore space) is volumetrically significant. Using Thomeer type curve analysis to fit the MICP data of our very large MICP data set, the pore systems’ volumes and entry pressures are quantified.

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.

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∞

Apply models within log domain. Solve for free fluid level by hydraulic zone. Model design. There are four common functions available within the SHM module: Brooks-Corey, Lambda, Thomeer, and Leverett-J function. Each functional solution has three coefficients.

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.

[33] Purcell W. R., Capillary Pressures – Their Measurement Using Mercury and the Calculation of Permeability Therefrom, J Petrol Technol 1949, 1, 39–48. 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.

To solve for capillary pressure and relative permeability numerically from two-phase flow Thomeer (1960) observed that the capillary pressure data from MICP experiments can be fitted with a hyperbola by using three fitting parameters like G, Pd, and \left ({V_ {\text {b}} } \right)_ { {P_ {\infty } }} as shown in Eq. (5): In this work, we developed a novel methodology, based on Thomeer formalism and optimization techniques, for 1D 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. model than that modified from Huet and Blasingame equation for estimating absolute permeability from mercury injec- tion capillary pressure data. The foundation of my new model is the petrophysical relation between absolute permeabil- ity and capillary-pressure/wetting phase saturation properties. 2017-08-20 · Capillary pressure and relative permeability correlations for understanding the dynamic behaviors of transition zones in carbonate reservoirs are utmost important in reservoir characterization and modeling.
