We can determine the downdip hydrocarbon column length by plotting a reservoir's static hydrocarbon pressure gradient vs. its hydrostatic pressure gradient. Hydrocarbon densities determine static hydrocarbon pressure gradients. The gradient is easily calculated when the density is measured. When density is not measured, charts are available to help estimate density.

This subsection shows how to determine oil and gas pressure gradients, make a plot of hydrocarbon pressure gradient, and determine hydrocarbon column length.
