The results illustrate how estimates of and obtained from four different isotropic estimation schemes [noninteracting, DS (Zimmerman, 1991), CPA (Berryman, 1980), and nonsymmetric self-consistent scheme of Budiansky and O'Connell (1976), and O'Connell and Budiansky (1977)] can then be used to predict what 2020-12-17 · The term "petrophysics" was coined by G.E. Archie and J.H.M.A. Thomeer in a quiet bistro in The Hague. By their definition, petrophysics is the study of the physical and chemical properties of rocks and their contained fluids. The T2 data and the hydrocarbon density, water density, free water level, and paleo-water level of the formation are processed to obtain parameters of Thomeer hyperbolas that closely conform to water saturation values obtained from the other well logs. The Thomeer hyperbolas so determined are converted to capillary pressure curves.
Corrected air permeability is the target variable. Applying developed permeability models in recent reservoir characterization workflow ensures consistency between micro and macro scale information represented mainly by Thomeer parameters and absolute permeability. The Thomeer database created is used by internally designed software, to apply these parameters for the geocellular saturation-height model for the multiltimodal pore systems in this reservoir. As a part of this process, detailed core to log integration, permeability prediction modelling, and well log quality control steps are utilized. Grain Size distribution Parameters The parameters of a millimeter plot or a phi plot can be determined from the following formulas (after Folk and Ward 1957 and Jorden and Campbell,1984.). ϕx is a grain size expressed in phi(ϕ) units such that x% of the sample is larger than this grain size.

Thomeer parameters for a multi-pore system of a Thomeer model are determined by evaluating an objective function that measures the mismatch between the well log data and modeled data having the PAPER TAKS FORCE BASIC RESERVOIR ENGINEERING Balikpapan 16 june 2014 Using Capillary Pressure Derived Parameters for Improving Permeability Prediction M. Deni Saputra, Khusnul Praptin Mulyana, Arfyan Rachmadani Petroleum Engineering , Sekolah Tinggi Teknologi Minyak dan Gas Bumi, Balikpapan, Indonesia ABSTRACT This paper presents the construction and verification of a new … 2016-01-19 · The Thomeer function has three parameters: Threshold pressure Pct Pore geometric factor G Mercury saturation at infinite capillary pressure SHg∞ Thomeer Hyperbola is determined by three parameters (two asymptotes): (1) P d, the displacement pressure required to first intrude mercury into the largest pore-throat; (2) G, the Pore Geometrical Factor, and (3) B ∞, the percent bulk volume occupied by mercury at infinite pressure (Thomeer, 1960; reproduced by permission of SPE). 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. 2020-10-01 · Thomeer parameters are related with the characteristic parameters of Thomeer PSD, including the peak position, the peak height and FWHM. The peak position moved toward larger capillary pressure with the increase of extrapolated displacement pressure and pore geometrical factor.

Thomeer parameters relate to the controlling parameters of Gaussian density function. 根据Thomeer参数提出了三种渗透率模型，并与以前的模型进行了比较 。 Not all curves, however, are hyperbolic and suitable for assignment of G values. Thomeer (1960) showed graphically that a relationship exists among air weakness related to the Thomeer curve fitting procedure: it is sensitive to heterogeneous pore- throat distributions, resulting in unrealistic Thomeer parameters.
This study has suggested that Gaussian error distributions are a better alternative than Thomeer hyperbolas for alluvial fan conglomerates, but future investigations are needed. Moreover, investigations of the Thomeer parameters were performed and the analysis showed: high correlation between the Thomeer parameter equivalent to largest pore-throat radius and permeability measured by CCA. 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. Moreover, investigations of the Thomeer parameters were performed and the analysis showed: high correlation between the Thomeer parameter equivalent to largest pore-throat radius and permeability measured by CCA. Thomeer suggested an pore geometrical factor. Thomeer suggested an empirical fit for f(G) = G -1.333.
