Abstract From the Canadian patent

A system and method for micro seismic fracture mapping using seismic source timing measurements for velocity calibration (28) and mapping. The system is deployed and coupled to a wire line (36) and a seismic source trigger with the sensor and transmitter coupled to the sensor with transmission of the time value of the first signal and the receiver and micro seismic velocity analyzer using receiving and transmitting of the first signal and the receiving and transmitting of the second signal transmitted to the analyzer (28) and the micro seismic velocity is calibrated based on the time difference between the first time value and a second time value associated with the second signal.
