– showing DST intervals (vertical thin lines and cross bars) * dots for well perforations in depth track, formation tops found in database are annotated along margin..


Pay (incremental hydrocarbon*Phi*h) (blue curve) and Sw (red curve) are shown in Track 4 using a single set of cutoffs:


Phi = 0.1
Sw = 0.5
Vsh = 0.3
BVW = 0.08


KHAN is used to predict pay in these wells, illustrated on next page.
