Abstract: Fracture monitoring and characterization of a subterranean fracturing process is described. Hydraulic fracturing conditions intended to induce tensile crack opening or compressional crack closure of a fracture responsible for a microseismic event in the Earth formation are selected and a hydraulic fracturing operation is performed using the selected conditions to cause tensile crack opening or compressional crack closure of the fracture responsible for a microseismic event in the Earth formation. Induced motion data from the microseismic event is received using a plurality of receivers, and the received data is analyzed to track the development of the fracture responsible for the microseismic event and/or to track a proppant distribution within the fracture.

Abstract: Processing strain measurement signals from a first measured signal representing a first received backscattered optical signal for a first sensor—the first measured signal associated with a first phase signal—and a second measured signal representing a second received backscattered optical signal for a second sensor. The second measured signal is associated with a second phase signal constituting a consolidation of the first phase signal and an additional phase signal—where the additional phase signal is unrecoverable from the first measured signal. The first phase signal is determined from the first measured signal and processed. The second phase signal is determined from the second measured signal, where the first phase signal and additional phase signal are indistinguishable in the phase domain. The second phase signal is processed to obtain the additional phase signal and a strain measurement signal is constructed using the processed first phase signal and additional phase signal.
