Sorrento field: water saturation (view source)
Revision as of 20:40, 9 September 2014
, 20:40, 9 September 2014→Sw-elevation plot
An S<sub>w</sub>-elevation plot ([[:file:predicting-reservoir-system-quality-and-performance_fig9-95.png|Figure 1]]) for study wells 4, 8, and 11 defines a trend of decreasing [[water saturation]] with increasing height. Well 1 is not on the same trend. Differences in water saturation attributable to differences in [[capillary pressure]]s are apparent but are not great enough to explain the discrepancy. Ignoring possible hydrodynamic effects, the difference in trends probably represents two separate oil columns and therefore two reservoirs.
