[%]
Given that the sample was taken from a point 100 ft above the oil-water contact,
what is the expected water saturation at that elevation? If the hydrocarbon
bearing thickness from the crest (top) of the structure to the oil-water contact in
175 ft, what is the average water saturation over this interval? (pw = 64 lbs/ft³
and po=45 lbs/ft²³.
