Second to mapping, but closely tied to it, is log analysis (see [[Log analysis applications]]). The computer can help by plotting multiple runs, curve types, and text information onto a composite log, or it can compute water saturation curves from input curves using the Archie equation or more complex variants of it. Crossplots of any curve against any other curve (such as a Pickett plot) can be generated. These types of analyses are not restricted to a single well. With the proper application program, an entire field study can be processed, complete with field-wide crossplots by zone. Often the output data from the log analysis process is imported into the mapping package to be contoured. | Second to mapping, but closely tied to it, is log analysis (see [[Log analysis applications]]).
