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.

Chapter 8: Capillary Pressure 8.1 Introduction and Theory Capillary pressure data are required for three main purposes: • The prediction of reservoir initial fluid saturations. • Cap-rock seal capacity (displacement pressures). • As ancillary data for assessment of relative permeability data.

This also demonstrates that the Brooks-Corey model and the This disclosed subject matter is generally related to methods for characterizing two-dimensional (2D) and three-dimensional (3D) samples to determine pore-body and pore-throat size distributions and capillary pressure curves in porous media using petrographic image analysis. 3 Feb 2016 Since the widely used mercury capillary pressure curves themselves can lead Prior to fitting the Thomeer-hyperbola all of the MICP curves has to be In order to be able to model initial water saturation the Pcl needs 12 Apr 2018 Theoretical background of Thomeer hyperbola rock typing. Thomeer (1960) observed that the capillary pressure data from MICP experiments can 7 Sep 2016 The main mathematical models for capillary pressure are the Thomeer [17], Brooks–Corey [18], van [19], and the three-constant hyperbolic Three permeability models were proposed based on the Thomeer parameters The peak position moved toward larger capillary pressure with the increase of 7 Sep 2016 The main mathematical models for capillary pressure are the Thomeer [17], Brooks–Corey [18], van [19], and the three-constant hyperbolic The analysis has shown that parametrization of MICP data using Thomeer It also describes capillary pressure models and porosity-permeability models. Thomeer proposed a model of the following form for describing mercury-injection capillary pressure data: Thomeer model . •The Thomeer model of capillary pressure is a hyperbolic relation between Mercury Injection.

Thomeer capillary pressure model

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 J. H. M., Introduction of a pore geometrical factor defined by the capillary pressure curve, J Petrol Technol 1960, 12, 73–77. [33] Purcell W. R., Capillary Pressures – Their Measurement Using Mercury and the Calculation of Permeability Therefrom, J Petrol Technol 1949, 1, 39–48. 2017-04-26 · The Thomeer function has three parameters: the threshold pressure P ct, the pore geometric factor G, and the mercury saturation at infinite capillary pressure S Hg∞. (Thomeer wrote Eq. 15.8 with bulk mercury saturation instead of mercury saturation. 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.

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). In 1960, Thomeer 2 proposed a relationship between capillary pressure and mercury saturation empirically: Equation 3 where pe is the entry capillary pressure of the rock sample, SHg is the mercury saturation, SHg8 is the mercury saturation at an infinite capillary pressure, and Fg … 2016-01-01 Mohamed S. El Sharawy 60 Thomeer (1983) model (Eq.

There are multiple pore structures among the selected core samples because of the various capillary pressure curves.

Chapter 7 - Introduction to Petrophysical Rock Types. Workshop. Day 4 will cover show how to convert lab measured capillary pressure data to reservoir conditions to determine height above free water, seal capacity and initial water saturation. The inputs to the models are air porosity, grain density, and Thomeer parameters obtained using mercury injection capillary pressure profiles. Corrected air permeability is the target variable.
