Mar 26, 2015 · A Buckles plot is a plot of water saturation (S w) vs. porosity. Contours of equal bulk volume water (BVW) are drawn on the plot. Points plot on a hyperbolic BVW line where the formation is near immobile water if the points come from a …

Apr 5, 2022 · Points scatter on a Buckles plot where the formation falls below the top of the transition zone. Figure 1 shows how a Buckles plot relates to capillary pressure, fluid distribution, and fluid recovery in a reservoir.

Water Saturation Crossplots. Learn about Hingle, Pickett, and Buckles plots, combining plots, uses of crossplots, examples.

This crossplot is used to determine a BUCKLE number from water saturation - porosity data sets. Typically core data are used. Each line represents a constant BUCKLE (bulk volume water) number and the value of each line is displayed as a label.

Jul 30, 2009 · In 1965, Buckles proposed that porosity and irreducible water saturation are hyperbolically related: Porosity×Irreducible Water Saturation=Constant The magnitude of the constant was shown to be related to rock type, and indirectly to permeability.

Download scientific diagram | Buckles plot; porosity values as a function of the water saturation (BVW) (Buckles 1965; Holmes et al. 2009) from publication: Integrated petrophysical and ...

Hingle Plot is also used to determine Rw, without having to compute porosity first. It can also display zones with different water saturation values. Buckles Number can give an indication if a certain zone is at irreducible water saturation and therefore will not produce any water.

One of the simplest and most widely used methods of estimating the advance of a fluid displacement front in an immiscible displacement process is the Buckley-Leverett method. [1], [2]. The Buckley-Leverett theory [1942] estimates the rate at which an injected water bank moves through a porous medium.

This is a recognized concept in the oil industry and its plot (Buckles plot) is typically applied for different reservoir parameter evaluations. This plot includes a family of hyperbolic curves, in which each one shows a constant BVW value, increasing this constant value has opposing relation with pore throat size (Figure 1).
