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. A prediction model for it is presented based on capillary pressure model, and the J-function prediction model is a power function

He also proposed, graphically, a relationship between air permeability and the introduced 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. 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.

2014-3-1 · Thomeer parameters, grain density and porosity were used as input parameters to the develop AI models. 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.

(e.g., Swanson parameter, area under the curve, threshold entry pressure, capillary pressure at different mercury saturations, Thomeer parameters, Brooks and parameters in the Gaussian density function relate more directly and intuitively to pore- system attributes than the parameters included in Thomeer's derivative.

The inputs to the models are air porosity, grain density, and Thomeer parameters obtained using mercury injection capillary pressure profiles. 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. 2021-03-27 Predicting Carbonate Rock Properties Using NMR Data and Generalized Interpolation-Based Techniques Theme Visible Selectable Appearance Zoom Range (now: 0) Fill Stroke; Collaborating Authors US20140350860A1 US13/902,333 US201313902333A US2014350860A1 US 20140350860 A1 US20140350860 A1 US 20140350860A1 US 201313902333 A US201313902333 A US 201313902333A US 2014350860 A Master's thesis in Petroleum engineering.
