Abstract: 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.

Abstract: A system and method for microseismic fracture mapping using seismic source timing measurements for velocity calibration is disclosed. The system may include a seismic source coupled to a wireline and a seismic source trigger, a sensor capable of detecting a first signal from the seismic source trigger, a transmitter coupled to the sensor, capable of transmitting a time value associated with the first signal, a receiver capable of detecting an event generated by the seismic source; and an analyzer capable of calculating a microseismic velocity of the event. In one embodiment, a first signal is transmitted through a wireline to trigger a seismic source. The first signal is detected, and a first time value associated with the first signal is transmitted. An event associated with the seismic source is detected and a second signal associated with the event is transmitted to an analyzer.
