| Abstract | A borehole radar prototype was designed based on theoretical considerations. Experiments were conducted at a granite quarry where an existing flam cut slot was used to simulate a fracture. The radar returns form this simulated fracture were detectable in boreholes located at distances of up to 12 meters from the fracture. Engineering design for a downhole radar system is almost complete. This system, including the directional antennas, is fabricate into a tool to be used in a borehole. |
