In this work, we developed a novel methodology, based on Thomeer formalism and optimization techniques, for 1D capillary pressure estimation using “standard” log data. With this methodology, capillary pressure will cover a larger volume of the reservoir than the volume covered by the SCAL.

I also incorporate characteristics of capillary pressure behavior using the classic Brooks-Corey power-law model. The final form of my new proposed model allowed us to Converting Capillary Pressures to the Height Domain. The pressure gradients for the oil and water phases are determined by the fluid densities. The water saturation distribution above FWL (or below FWL for a negative capillary pressure in an oil-wet system) is controlled by the balance of capillary and buoyancy (gravity and density Current Filters. entry pressure Feature Thomeer hyperbolas, Gaussian distribution functions, Reservoir Characterization, MICP-based rock/pore typing Number of pages: 84 + supplemental material/other: 1 Stavanger, 15.06.2019 Title page for Master's Thesis 4.4 Capillary Pressure Models Model capillary pressure data shapes.

Thomeer proposed a model of the following form for describing mercury-injection capillary pressure data: ..(3) in which S Hg is the saturation of mercury. The Thomeer function has three parameters: Threshold pressure P ct; Pore geometric factor G; Mercury saturation at infinite capillary pressure S Hg∞ 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. For more information: A Thomeer forward-modeled capillary pressure curve can be generated from insight into the generating parameters that can come from a variety of sources of rock data, from cores to cuttings and the Shell Rock Catalog (Thomas et al., 1995).

Abstract. A method is presented that provides a mathematical description of capillary pressure curves and, probably, of differences in pore geometry of samples. The technique is based on the observation that the location and shape of a capillary pressure curve reflect characteristics of the pore structure of the sample.

The new capillary-pressure model is applied to evaluate sealing capacity of seals, calculate transition zone thickness and saturation above free water level in reservoirs. Good results are achieved through integration of well log data, production data, core, and geological concepts.

The above equation gives the mapping between the elevation and the capillary pressure. The capillary pressure is proportional to the elevation above the free water level and the constant of proportionality is the product of the density difference and the acceleration due to gravity.

This module discusses the construction of a capillary pressure model at the core scale. The first lesson focuses on the methodology used in Saturation Height Modeling (SHM), while the second lesson presents a step-by-step example in Techlog. The breakthrough pressures (Pb) and Thomeer shape factors (C) are defined for each capillary pressure curve We did this using data up to 1000psi mercury capillary pressure because this equates to the maximum reservoir thickness i.e. 200m Thomeer Model in a Tight Gas Reservoir Converting Capillary Pressures to the Height Domain.
