Buckles plot
Revision as of 17:49, 17 April 2014 by FWhitehurst (talk | contribs)
A Buckles plot is a plot of water saturation (Sw) 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 reservoir with consistent pore type and pore geometry.
- 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.
