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.

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. He also proposed, graphically, a relationship between air permeability and the introduced parameters. Thomeer J. H.

R., Capillary Pressures – Their Measurement Using Mercury and the Calculation of Permeability Therefrom, J Petrol Technol 1949, 1, 39–48. Abstract.

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 DOI: 10.2118/105139-MS Corpus ID: 140667487.

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: 2016-01-19 · This procedure of Eq. 2 has been applied to the conversion of mercury capillary pressures to oil/water, gas/oil, and gas/water capillary pressures. The results are mixed: sometimes it works well, and sometimes it does not. Thomeer model.

level is defined as the elevation where the capillary pressure is zero. The above equation gives the mapping between the elevation and the capillary pressure. The capillary pressure is proportional to the elevation above the free water level and the constant of proportionality is the product of the density difference and the acceleration due to gravity.

200m Thomeer Model in a Tight Gas Reservoir In this chapter we will discuss how the capillary pressure curve determines the hydrostatic distribution of fluids in porous media. We will also see that capillary pressure can have a significant effect in dynamic displacement processes. Capillary pressure adds the second spatial derivative of saturation to the mass conservation equations.

Chapter 6 - Common Applications (Thomeer and Leverett J) Workshop. 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.

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 … A Capillary Pressure Function for Interpretation of Core-Scale Thomeer (1983), as well as Polynomial, Sigmoidal, Exponential (e.g., such as poor matches of threshold pressure and irreducible/residual fluid saturation, as well as inability to model a sharp capillary transition. 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. 2018-04-12 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). 2017-04-26 2017-08-20 2016-01-01 lary pressure and related forces in most cases.

With this methodology, capillary pressure will cover a larger volume of the reservoir than the volume covered by the SCAL. J. H. M. Thomeer, “Introduction of a Pore Geometrical Factor Defined by a Capillary Pressure Curve,” Transaction of AIME, Vol. 219, No. 2057, 1960, pp. 354-358.

SCAL is a time consuming and expensive procedure. As a result: only few measurements of capillary pressure can be done and capillary pressure In this study, eight permeability models are calibrated to a large mercury injection capillary pressure dataset obtained fromtheMiddleEastregion.Thepermeabilitymodelsare:Purcell,Thomeer,Winland 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.
