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]]).
