Determining water saturation

Water saturation can be measured directly from a sealed core, which is an expensive method, or it can be calculated from the Archie equation,[1] which is less expensive. Sw can also be estimated using a graphical representation of the Archie equation known as the Pickett crossplot.[2] 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.
