Rw Calibration (All Formations, Data-Discovered)
Same Pickett-plot Rw fit as the main Rw Calibration card, but not limited to a hand-picked list of 10 formations -- every formation with enough qualifying wells is found directly from the data. Built after a real gap was found this session: well 9/09a- 11's two correctly-recorded gas shows (71m and 97m thick) sit in Beryl Formation, which was never in the original 10 and so never entered Rw/Sw at all. Writes its own separate results -- the original 10-formation card is completely unaffected by this one.
What "accuracy" means here: The formation list itself is discovered from the data (any formation with at least 10 qualifying wells by default), not hand-picked -- so the set of formations shown here will differ from, and is not a replacement for, the original 10-formation Rw Calibration card. Results are written to separate database rows from that card and never overwrite its numbers.

Pickett Plot
Both axes are log scale. Small dots are individual depth samples (downsampled for display). Diamonds are the porosity-binned lower-envelope points the fit actually used. The line is the fitted Sw=1 (100% water-saturated) line -- real hydrocarbon-bearing rock at the same porosity should read to the right of it (higher resistivity).
