This report describes progress on the project, "Fractured Reservoir Discrete Feature Network Technologies" during the period March 1, 1998 through May 30, 1998. The report presents summaries of technology development for discrete feature modeling in support of the TAGS process. In addition, the report provides information on project status, publications submitted, data collection activities, and technology transfer through the world wide web (WWW).
