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):
A method of determining location of end portions of a fracture in a subsurface formation at a depth of interest penetrated by a well, comprising steps of:\n (a) moving in the well to the depth of interest a well logging sonde containing (1) a ground penetrating radar transmitter and (2) at least one radar receiver at a distance from the ground penetrating radar transmitter; (b) emitting a ground penetrating radar pulse of electromagnetic energy from the ground penetrating radar transmitter in the well logging sonde at the depth of interest; (c) receiving ground penetrating radar electromagnetic energy with the at least one radar receiver in the well logging sonde at a distance from the ground penetrating radar transmitter by performing steps of:\n (1) sensing arrival of a first break of the ground penetrating radar pulse indicating the spacing of the radar transmitter and radar receiver; and \n (2) sensing arrival of a second break of the ground penetrating radar pulse indicating presence of a fracture as a secondary electromagnetic energy source; \n (d) sensing arrival times of the first break pulse and the second break of the ground penetrating radar pulse by the radar receiver; (e) determining from the arrival times of the second break of the ground penetrating radar pulse the location of end portions of the fracture in the subsurface formation.
