AB  - We are presenting a first example of 3D frequency domain acoustic inversion applied to a synthetics data over a shallow channel. High resolution images are obtained in less than a day CPU time using inexpensive hardware by utilizing a point iterative solver for wave equation modelling part of the code and multi shot approach. Tests have shown that it is possible to combine multiple shot positions and reduce time required for computation dramatically. Final recovered velocities are within 4% of the true velocity once and spatial positioning I quite well. We did not use any apriori information on anomaly position nor size.
