Sw by Stratigraphy (Wells South-North)
Visualizes the range of Sw seen in sand bodies across wells, organized by stratigraphic unit (Group/Formation/Member level) and by well position South to North. Each point is one sand interval's median Sw, computed with that SAME interval's own fitted Rw from the Rw Calibration (Per Sand Interval) card -- not a formation-level average -- so the granularity matches how Rw was actually calibrated. Not restricted to a fixed formation list: any stratigraphic unit with interval-level Rw evidence can be picked, up to 10 at a time, directly on the chart.
What "accuracy" means here: No hydrocarbon/water-leg restriction is applied here (unlike the Sw validation cards) -- every Phase4-Sand depth in an interval contributes, so a point can reflect a genuine hydrocarbon show (low Sw) or a wet interval (Sw near 1). This card is a visual exploration tool, not a precision/recall test against a known ground truth.

Sw by Stratigraphy (Wells South-North)
Each point is one sand interval's median Sw, computed with that interval's OWN fitted Rw (Rw Calibration Per Sand Interval card), not a formation average. Wells are ordered South to North by wellhead latitude. Colour marks the selected stratigraphic unit -- picking a Group-rank unit automatically includes its resolved Formation/Member children.
