Conventional saturation-height methods used by the oil and gas industry are in the literature for determining field-wide saturation-height functions based on on Thomeer's original set of pore geometrical factors, relating satu
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).
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).

Techlog Saturation Height Function Workflow Saturation-height function is used to predict the saturation in the reservoir for a given height above the free water level. The authors investigate performance of eight saturation-height methods (i.e., Leverett, Cap-Log, Modified Cap-Log, Johnson, Cuddy, Modified Cuddy, Skelt-Harrison, and Sodena methods) employed in the oil industry.
Upscaling is difficult when desiring to honor and retain the information obtained from core descriptions, facies classifications and mercury injection Who use saturation-height function Geologist uses it to generate GIIP or OllP in his static model The result of static model is passed to Reservoir Engineer for the starting point of his dynamic modelling (history matching). Methods disclosed herein may create a saturation-height function by: quantitatively measuring microporosity, using techniques such as laser scanning confocal microscopy and/or MICP data; determining the distribution of facies and microporosity as a function of depth using techniques such as conventional openhole logs, core, borehole images, nuclear magnetic resonance (NMR) logs, and analysis of sequential core samples using confocal microscopy and/or MICP; and evaluating the effect of 2015-06-24 · In a manner similar to that described in the previous P c /S w section, height/saturation curves are often fitted to these resistivity-log-derived S w data to enable reservoir hydrocarbons-in-place volumes to be calculated. The function forms are similar to or are the same as those described above for P c /S w. Fully Upscaled Saturation-Height Functions for Reservoir Modeling based on Thomeer's Method for Analyzing Capillary Pressure Measurements Buiting, Jan Jack ( Saudi Aramco ) March, 2007 – OnePetro 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 and microporosity as a function of depth; and calculating the saturation-height function for a given formation. Saturation-height functions in oil and gas Data Interpretation Thomeer Curve Fitting: Rock Typing • Thomeer model is extensively used to fit the Pc curves (hyperbolic function) for saturation height modelling and rock typing • Fitted curves are defined by the pore structure factor (G), threshold pressure (Pd) and the total interconnected pore volume (Sb∞) (Bulk Volume saturation at infinite pressure ~ Porosity) • LR-Senergy •Leverett-J Functions •FOIL Functions •…To name a few… 0 20 40 60 80 100 120 140 160 0.00 0.20 0.40 0.60 0.80 1.00 L Saturation - v/v “A method of estimating Saturation based on the height above the free-water-level and capillary pressure” After applying this correction, saturation height models are developed from core capillary pressure (Pc) data to calculate water saturation vs. depth, which is independent of logs. First step of the procedure is to model capillary pressure measurements using different methods, namely, Brooks-Corey, Lambda, Thomeer and Leverett-J functions.

Workshop Chapter 8 - Applied Saturation Height Model Using Petrophysical Rock Types. The saturation-height function greatly impacts reserve calculations and is used by geologists or reservoir engineers to predict the saturation in the reservoir for a Prado A, Selman M.
