Unconventionals & CO2 Storage. Quality Control of Functions - Checking for “Good Behaviour” HAFWL = Height above FWL (m) Rhow / Rhohc = Water and Hydrocarbon density (SG) 1.2406 = Conversion (psi/m) Method: Calculate J value for each known saturation cell (logs etc) Plot J vs known Sw (altogether &/or by facie) If reasonable relationship(s) evident, use J vs Sw as proxy for your Saturation height function The Saturation-Height Modeling module provides core-to-log integration via the following workflow: Template loading of special core data. 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. 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. The two best known methods to analyze MICP measurements and to estimate saturation height curves are Thomeer-and Leverett J functions.

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. (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. 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).

2016-09-07 · The function was derived based on a capillary bundle model. However, the dependence of the J-function on the saturation Sw is not well understood. A prediction model for it is presented based on capillary pressure model, and the J-function prediction model is a power function instead of an exponential or polynomial function.

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. 2017). Presentation to illustrate links between saturation height relationships, permeability and flow prediction. Saturation modeling features.

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
