"Downhole Explorer is an exceptionally smart drillhole presentation and plotting program with many innovative features. On-line tutorials and wizards make the program extremely easy to use. For example, the document wizard makes it possible for the first time user to build an entire project complete with section plots and log sheets in a matter of minutes."

The specification for Earthworks Downhole Explorer was based on the original MS-DOS based GeoBASys application.  John Davis developed Downhole Explorer in association with MICL (Datamine) between 1999 and 2003.  The application was also used to provide Eathworks Present for Datamine.
