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. Sw can also be estimated using a graphical representation of the Archie equation known as the Pickett crossplot. This subsection discusses how to calculate Sw using the Archie equation, how to determine values for variables of the Archie equation, and how to make a Pickett crossplot.
