Hydrocarbons are daily becoming more difficult to locate in the subsurface. The future major discoveries will most likely come from stratigraphic traps, and one of the most valuable stratigraphic tools is gathering dust in almost everyone's files. This stratigraphic tool is the well log. With massive, inexpensive, well-log digitization capabilities and computer software for analysis of data from these logs, the routine, expensive, time-consuming work can be reduced drastically and permit the geologist to do more creative exploration. Results from the computer analysis of digital logs from many wells have developed leads for exploration trends, have located possible bypassed hydrocarbon-bearing zones, and have indicated better productive zones within a well.
