Area versus depth below sea level plot for the example prospect used to generate the gross rock volume (GRV) (shaded polygon). In this trial, the GRV (31,844 ac-ft) includes a vertical reservoir gross thickness of 115 ft and an oil–water contact at −6150 ft such that the area equals the 400 ac discussed in Figure 1, with an associated hydrocarbon column height of 200 ft down from the crest.
