The residual oil saturation as a function of the initial oil saturation, f(S oi). This relationship can be determined experimentally. The S oi /S or relationship model includes Land’s type, Suzanne type (plateau type), and Linear correlation type. It needs to be determined by special core analysis (SCAL) data.

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 two best known methods to analyze MICP measurements and to estimate saturation height curves are Thomeer-and Leverett J functions. 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.

Despite log-based water saturation (Archie) and core measurements (Dean Stark) indicating more than 80% water saturation for less permeable reservoir rocks within the oil leg, production tests did not produce water at 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. Thomeer Feature.

The popular J-function method usual starts with a classification of pore systems using the parameter. The results of this study show that the most commonly used Leverett-J model is one of the poorer performing saturation-height functions. Of the conventional "equation based" approaches, the Thomeer and Skjaeveland models appear to have the most utility and are recommended as first choice saturation-height models to test. 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∞ (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.

This functions correlated data over several orders of magnitude change in permeability. Also, notice that the J function value where most of the saturation change occurs is close to the value of 0.49 for a bundle of identical capillary tubes.

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. 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.

(The square root sign is missing in Figure 6.) Notice that the wetting phase saturation appears to plot the weight retained on each tray as a histogram as in Fig. 3.3. A histogram shows what percentage by weight of the grains fall within a particular size range. This type of presentation gives a good visual impression of the distribution of grains in the various size categories.
