Hence, when it comes to building reservoir models and estimating volumes in-place, capillary pressure based saturation-height models are used to describe Sw. OURSE OJETIVES the target audience.

Input includes high-resolution petrographic images and laboratory-derived porosity measurements. 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.

• Thomeer function • Lambda function The established model of Pc versus Sw can be used for formation characterization or in other words, rock typing and Flow Unit characterization. • Pore throat size distribution • Displacement pressure • Estimation of Permeability • Assessment of the degree of heterogeneity Capillary pressure (P c) is the difference in pressure measured across the interface in the capillary (P c = P nw - P w).

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). Capillary Pressure Model.

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. 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 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 … 2014-09-01 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. 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.

Andy May (10/2/2013) The capillary pressure model is based entirely upon special core analysis. Following is a description of the model.

It also describes capillary pressure models and porosity-permeability models. In Chapter 5, the MICP parametrization workflow used in this thesis is described. Chapter 6 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. predict permeability. Nine Permeability models that use mercury injection capillary data are compared using a through statistical and graphical analysis. The permeability models are: Purcell model, Thomeer model, Winalnd model, Swnson model, Pittman model, Huet-Blasingame model, Dastidar model, Injection Capillary Pressure Data,” Paper [22] W. R. Purcell, “Capillary Pressure—Their IPTC 10994 Presented at the 2005 Measurement Using Mercury and the International Technology Conference, Calculation of Permeability There Form,” Doha, 21-23 November 2005, 12 p.

The final form of my new proposed model allowed us to predict absolute permeability as a function of effective porosity, irreducible wetting phase saturation, displacement or threshold pressure corresponding pore throat radius, and basic pore size characteristics. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): phase trapping, Hysteresis We discussed in CENG 571 how the pore size distribution may be characterized measuring a mercury- air (vacuum) capillary pressure curve for a rock sample.

Two-phase capillary pressure is relatively easy to measure in the laboratory, but three-phase capillary pressure is seldom available from experiments. Kalaydjian’s paper (1992) is one of the few reported cases of measurements of three-phase capillary pressure. One common way to model three-phase capillary pressure is by using weighted averages

The capillary pressure curves can characterize the pore structure of the core samples. There are multiple pore structures among the selected core samples because of the various capillary pressure curves. New Mexico Institute of Mining and Technology A comparison of the capillary pressure derived water saturation and that from a conventional Simandoux porosity-resistivity model is shown below. Example showing SWpc (black), SWsimandoux (blue), SWcore (black dots), and SOcore (red dots) in Track 5.

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 …

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. 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.
