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. The peak position moved toward larger capillary pressure with the increase of extrapolated displacement pressure and pore geometrical factor.

Thomeer (1960) proposed the following model: (1) S b S b ∞ = e − F g / log (P c P d) where, S b is the bulk volume (in percentage) occupied by mercury, S b ∞ is the bulk volume (in percentage) occupied by mercury at infinite capillary pressure or the total interconnected pore volume, F g is a parameter that defines the capillary pressure curve Thomeer Parameters and Petrophysical Rock Types: A Thomeer hyperbola is fit to the HPMI data by optimizing on the Thomeer Parameters G1, Pd1 and BV1 for the first pore system and G2, Pd2 and BV2 for the second. The following image relates the Thomeer hyperbola (dashed black line) to the Capillary Pressure Curve (solid black line). The Thomeer permeability can be computed for all samples with MICP Thomeer parameters. Thomeer gave no instructions as to the contribution to permeability from a multiple-pore system.

These 5.1 A family of capillary pressure curves showing Thomeer’s three parameters: 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). 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. Corrected air permeability is the target variable.
