abstract:This paper presents a study on the hydraulic properties of fractured rocks using a borehole acoustic televiewer and double packer system. Two deep boreholes located in Kaohsuing, Taiwan were tested in this study. The paper characterizes the hydraulic properties for the two test sites and concludes that infillings, lithology, and interconnectivity of fractures are significant factors affecting the hydraulic properties of fractured rocks. The borehole-geophysical logging from the televiewer was proven to be a highly efficient way to obtain useful information (eg. positions of geological structures and fractures) for hydraulic testing during hydrological investigations.
