Compare three capillary pressure models with named inputs: Brooks-Corey, Van Genuchten, and Leverett J-function. 20 saturation points with J-function scaling chart.

A log display for one vertical well. Paste SP, gamma-ray and shallow, medium and deep resistivity onto the Log Data sheet — any sampling interval, depth increasing downward — and the Well Log sheet draws them as tracks against depth: SP as bars either side of a shale baseline, GR as bars coloured by a five-band palette, a lithology column from the same palette, resistivity on a logarithmic scale with decade lines, and a computed shale-volume track from the gamma-ray index. The tracks are charts over a grid of cells that supplies the depth lines and labels, and the sheet prints on one page. No add-in is needed.
