Abstract
The present invention is directed to a wireless fracture-mapping tool utilized for determining fracture directional and length characteristics of hydraulically induced fractures in subterranean earth formations containing recoverable energy values. The apparatus of the present invention utilizes antenna packages from which a transmitting antenna is propelled from a wellbore penetrating the earth formation into the fracture system. Signal-receiving antennas disposed on opposite sides of the transmitting antenna are likewise propelled into the fracture system for receiving signals from the transmitting antenna that are indicative of the fracture orientation and length. With the present invention the axial and singular three-dimensional location of the fracture or other fracture profiles may be readily mapped. This fracture-mapping system of the present invention aids in the recovery of the energy values from the subterranean earth formation by facilitating the strategic emplacement of wellbores to more efficiently recover the energy values in the subterranean earth formations.
