There are different methods to calculate the HCIIP from simple calculations of using average values to complex geomodels which take account geological trends and account for the capillary forces in the hydrocarbon column. Over the years different methods were developed to describe the changing water saturation in the reservoir with height above the free water level and also taking the reservoir quality into account.

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).

Saturation Height (SwH) functions may address all these properties, including permeability, but relies on the variation of saturation as function of the Height Above the Free Water Level (HAFWL) or capillary pressure.

Graphical review and edit for QC. Transform or normalize pressure data. The results of this study show that the most commonly used Leverett-J model is one of the poorer performing saturation-height functions.

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. In order to characterize the pore structure of complex carbonate, a modified multimodal Thomeer pore size distribution (PSD) function was developed, which was based on the multimodal Gaussian density function and three controlling parameters including peak position, peak height and full width at half maximum (FWHM). Saturation-height functions in oil and gas reservoirs are determined using methods that include quantifying the microporosity of the subterranean formation; determining the distribution of facies Selection of Saturation-Height Models - Leverett-J, Brooks-Corey, Lambda, Thomeer, Skjaeveland, Machine Learning & Neural Networks, Interpolation Saturation-Height Function Creation - Model Fitting, Individual Curve Correlation Method, All Curves Simultaneously Method, Problems with Parameter Selection, Recommended Initial Parameters for the These functions calculates Sw based on one or more of the parameters like porosity, oil water contact, gas water contact, irreducible water saturation, height above contacts, etc.

This type of presentation gives a good visual impression of the distribution of grains in the various size categories. In particular, it is easy to see how The saturation plateau as a function of local disorder for six contrasting kaolinites exposed to He + ion beam is shown in the inset of Fig. 4.4.The defect concentration at saturation increases with the local crystalline disorder of kaolinite, as estimated from structural Fe 3 + local probes (Gaite et al., 1997).

First step of the procedure is to model capillary pressure measurements using different methods, namely, Brooks-Corey, Lambda, Thomeer and Leverett-J functions. 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.
