Water saturation can be measured directly from a sealed core, which is an expensive method, or it can be calculated from the Archie equation, which is less expensive. S<sub>w</sub> can also be estimated using a graphical representation of the Archie equation known as the Pickett crossplot. This subsection discusses how to calculate S<sub>w</sub> using the Archie equation, how to determine values for variables of the Archie equation, and how to make a Pickett crossplot.
