Following the standard supervised machine learning practice, the dataset was divided into two parts where 80% is used for training and 20% for blind testing. 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. 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 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).

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.

Each curve can be uniquely defined by specific values 2019-12-4 · permeability models are: Purcell model, Thomeer model, Winalnd model, Swnson model, Pittman model, Huet-Blasingame model, Dastidar model, Buiting-Clerke model using Laplace transform and Buiting-Clerke model using Thomeer parameters. The adapted methodology used in this comparative study is to compare all models with their published 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).

Thomeer parameters

In 1960, Thomeer showed that each capillary pressure curve using mercury injection method can be described using three pore-network parameters. 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.
