- A method to locate fractures adjacent to, but not intersecting, an uncased wellbore would be a great aid to the geothermal industry. A prototype downhole radar probe was recently completed with the aim of locating fractures near a single wellbore. This probe, operating in the pulse mode with a bandwidth of 30 to 300 MHz, contains two identical directional antennas. As with any prototype instrumentation, extensive field work is required to completely understand the characteristics of the system. A first step in that understanding is to operate the instrument under known or controlled conditions. In this paper, some tests of the radar probe in a travertine quarry using a known target are reported. In the tests, the target is clearly detected from a borehole located 14 ft away. 12 refs., 5 figs., 1 tab.
