Because most downhole reservoir evaluation tools are unable to successfully detect very thin bedding, it is difficult to evaluate the production potential of laminated formations and small natural fractures. The availability of logging tools that provide higher data sampling rates has made the study of in-situ, fine-scale formation features possible. Tools such as the Formation MicroScanner* (FMS), Borehole Televiewer (BHTV), and the High-Resolution Dipmeter are able to show images of borehole walls. However, the interpretation of borehole images relies on the quality of the image data presented. Fine-scale formation features such as bedding will not be recognized if the presentation of the images is unclear.

The purpose of this paper is to provide an inexpensive and intuitive way for enhancing and displaying borehole images. The advent of 32-bit microcomputers and windowing software on PC's makes the availability of inexpensive platforms for viewing, analyzing, and interpreting data possible. We have developed a prototype system for image analysis and image processing of FMS and BHTV field data. The software represents the first stage towards a borehole image understanding system.
