Kashtan (St.-Petersburg State University) V.A. Korneev (Lawrence Berkeley National Laboratory) & A. Sidorov (St.-Petersburg State University) SUMMARY We apply tube-wave monitoring method to a time-lapse cross-well dataset from Mallik field. Raw waveforms are used for analysis thus avoiding any smearing of 4D response introduced by pre-processing. We perform extensive modeling that includes effects of a source borehole and confirms nature of most prominent arrivals as being tube-wave related. Modeling proves that strongest conversion of tube wave into P and S
