Petrophysical analysis utilizing digital-log information has recently become a recognized tool in the search for oil and gas. Until now, this method has not been widely used in exploration programs, due to the unavailability of a mass of accurate, inexpensive digital-well-log data and adequate computer software to completely analyze the data.

These data and analysis capabilities are now available to the oil industry and can be readily used in modern petroleum exploration programs.

Results from computer analysis of digital logs from many wells can develop leads for exploration trends, locate possible bypassed hydrocarbon-bearing areas, and better indicate productive zones within a well.
