Export of equations to reservoir modeling software. track it aims to highlight a set of derivable parameters of mercury capillary curves using the Thomeer-method. Since the widely used mercury capillary pressure It may be expected that parameters in such a relation can then be used to describe differences in pore geometry of these samples. For a practical description of 6 Jun 2019 The shape of this function is determined by three Thomeer parameters: - Pd is the “Minimum Entry Pressure” related to the largest pore throat;.

This results in a full characterization of the entire pore space of each core plug. 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.

The Thomeer hyperbolas so determined are converted to capillary pressure curves. The Thomeer-Corey alpha parameter [Pa-1]. LAMBDA
2020-10-1 · 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.
Theme Visible Selectable Appearance Zoom Range (now: 0) Fill Stroke; Collaborating Authors 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 Thomeer parameters as input. 2016-09-07 · 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 dependence of the J-function on the saturation Sw is not well understood.
The Thomeer hyperbolas so determined are converted to capillary pressure curves. Our PRTs are derived from Thomeer analyses of up to 1,500 mercury injection capillary pressure (MICP) curves. Thomeer analysis involves the fitting of the Thomeer hyperbola to core plug MICP data by determining the Thomeer parameters (initial displacement pressure, geometric factor, and bulk volume mercury injected). 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.

Thomeer parameter, P d, when plotted on a logarithmic axis [Log (P d) domain] showed the most significant variation, and it was considered the controlling parameter for classification. We observed four distinct and separable modes (Figure 5) and fitted each with a Gaussian distribution, termed a Porositon.
