3D Frequency Domain Waveform Inversion – Synthetic Shallow Channel Example

C026 3D Frequency Domain Waveform Inversion – Synthetic Shallow Channel Example I. Stekl* (Imperial College London) M.R. Warner (Imperial College) & A.P. Umpleby (Imperial College) SUMMARY 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
