Abstract:
Ground penetrating radar (GPR) measurements from a downhole well tool in a wellbore are obtained to identify length of fractures adjacent the wellbore. A ground penetrating radar transmitter of the downhole tool emits an electromagnetic pulse. The electromagnetic wave of the ground penetrating radar is diffracted on encountering an end or tip of a fracture, which acts as a secondary source. The diffracted signal is then collected by downhole receiver(s) of the downhole tool. Length of the fracture is determined based on the time of travel of the electromagnetic wave from its emission until its collection as a diffracted signal by the downhole receiver(s).

Claim (Index 1):
An apparatus for determining location of end portions of a fracture in a subsurface formation penetrated by a well, comprising:\n (a) a well logging tool adapted for movement in the well by a well logging cable, the well logging tool comprising:\n (1) a ground penetrating radar transmitter emitting electromagnetic energy in the well at a depth of interest: \n (2) a radar receiver receiving ground penetrating radar electromagnetic energy in the well at a distance from the ground penetrating radar transmitter; \n (3) the radar receiver sensing time of receipt of the ground penetrating radar electromagnetic energy by the radar receiver: \n (4) downhole telemetry transmitting the sensed time of receipt of the ground penetrating radar electromagnetic energy over the wireline logging cable for processing; \n (b) a data processing system determining from the sensed arrival time of the received electromagnetic energy the location of end portions of the fracture in the subsurface formation.
