Claim:
1. A method of real time diagnostic of fracture operations, the method comprising: performing fracture operations in a wellbore comprising forming a fracture in communication with the wellbore; recording microseismic activity generated by the fracturing operations; determining microseismic event locations; generating tube waves to propagate along the wellbore toward the fracture and reflect from the fracture along the wellbore; recording the tube wave reflections from the fracture in real time; analyzing the microseismic event locations and the tube wave reflections from the fractures; using the tube wave reflections to orient seismic sensors and to calibrate a seismic wave propagation velocity model; determining leakage in a plug associated with the wellbore based on the tube wave reflections; and performing a remediation operation based on the determined leakage; wherein the seismic sensor orientation and the seismic wave propagation velocity model calibration comprise: calibrating the microseismic wave propagation velocity model.
