Abstract: A method includes drilling a wellbore into a subsurface using a drill bit and, for each of a plurality of depths of the drill bit in the wellbore, detecting, at each of a plurality of receiver stations located along a fiber optic cable disposed behind a casing string within the wellbore, a seismic signal created by the drill bit drilling the wellbore, sending an optical signal generated by the detection of the seismic signal from each of the plurality of receiver stations to an interrogator, sorting, using a computer processor, the optical signals by receiver station, and determining, using the computer processor, a seismic velocity using first breaks picked from the sorted optical signals.

Abstract: A system and a method for generating a subterranean map with ground penetrating radar are described. The system includes multiple ground penetrating radar transmitters, multiple ground penetrating radar receivers, and a controller. A first subset of the transmitters radiate a first signal at a first frequency bandwidth, a second subset of the transmitters radiate a second signal at a second frequency bandwidth different than the first frequency bandwidth, and a third subset of the transmitters radiate a third signal at a third frequency bandwidth different than the first and second frequency bandwidths. The receivers receive a first return signal at the first frequency bandwidth, a second return signal at the second frequency bandwidth, and a third return signal at the third frequency bandwidth and transmit the return signals. The controller operates the ground penetrating radar transmitters, receives the return signals, and generates a subterranean map from the return signals.
