If a P<sub>c</sub> curve is available, then a profile of S<sub>w</sub> can be approximated using information from the curve. To make an S<sub>w</sub> profile of a reservoir using a P<sub>c</sub> curve, use the table below.
If a P<sub>c</sub> curve is available, then a profile of S<sub>w</sub> can be approximated using information from the curve. To make an S<sub>w</sub> profile of a reservoir using a P<sub>c</sub> curve, use the table below.
# Convert pressure scale (Y-axis) to hydrocarbon column length ( ''h'' ), where h = P<sub>c</sub> × conversion factor (if conversion is unknown, use 0.7 for oil and 0.4 for gas).
# Using the same scales, plot the curve next to a [[Cross section#Structural cross section|structure section]] showing the trap. Place the base of the curve at the free water level (see Figure 9-23).
# Estimate S<sub>w</sub> for any point in the reservoir by reading the S<sub>w</sub> that corresponds to the depth.
