The Thomeer function has three parameters: Threshold pressure P ct; Pore geometric factor G; Mercury saturation at infinite capillary pressure S Hg∞ (Thomeer wrote Eq. 3 with bulk mercury saturation instead of mercury saturation. Bulk mercury saturation equals the product of porosity and mercury Saturation-Height Equations There are various practical techniques for correlating capillary pressure curves according to rock type for a heterogeneous formation and generating field wide saturation-height function that relates capillary pressure curves to porosity, permeability or rock type in general. The classic method is based on Hence, when it comes to building reservoir models and estimating volumes in-place, capillary pressure based saturation-height models are used to de- scribe Sw. For unconventional reservoirs, even if capillary pressures are not controlling Sw, saturation-height modelling provides a means to describe Sw variations in reservoirs using property variations. The saturation height functions can describe the drainage process during the hydrocarbon migration and are expressed as a relationship among the saturation, the height above the free water level and some model properties (commonly porosity and permeability). The Thomeer function parameterization of MICP data has been shown to upscale (Buiting, 2007). Square Root K/Ø Methods: Leverett J Function and Flow Zone Indicator (FZI) Technique Whereas the Thomeer method has been used for many years in Shell, in other companies the Leverett J Function method ( Leverett, 1941 ) and the related FZI technique Thomeer (1983), as well as Polynomial, Sigmoidal, Exponential (e.g., Skelt and Harrison, 1995) and Hyperbolic functions. These functions have been found useful for describing saturation-height (i.e., P c) relationships in specific field cases, but they may suffer from limitations such as poor matches of threshold pressure and irreducible Pore structure of carbonate reservoirs is complex and multimodal.

2019-05-03 · Saturation Height Function kokokyi Uncategorized May 3, 2019 1 Minute Further to the presentation on “Saturation Height Function” (prepared by Mr Leong) which I posted previously, I would like to stress that Leverett-J method of generating SHF is one of the many methods used in the industry. Applying different saturation height models “A saturation height model is an equation that represents the water saturation profile in a reservoir interval as a function of the fluid/rock properties and the distance above the Free Water Level (FWL) and is constructed from capillary pressure data” (Valentini et al.

However, neither method has been satisfactorily upscaled until now. The popular J-function method usual starts with a classification of pore systems using the parameter. 2020-10-01 · 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. Saturation Height Modeling 1/2.

J- Function Techlog SHM module (Saturation Height Modeling) allows to build Thomeer function to obtain mathematical model of water saturation from capillary pressure. 6 Jun 2019 The capillary pressure in a reservoir determines the saturation distribution The shape of this function is determined by three Thomeer parameters: Buiting, J. [ 2007] Fully Upscaled Saturation-Height Functions for Re relationship, capillary pressure profile and water saturation for a given height above free The ones discussed here are the Leverett J-function, Thomeer model,.
