- Аннотация: Far-field sonic imaging is becoming a well-established tool for high-resolution structural imaging in the vicinity of the borehole. Spectral element modelling (SEM) is proposed and evaluated as a prospective technique for use as a forward modelling engine for sonic imaging. The correctness of the approach is validated by successfully comparing the results against the analytical solution. The tests of SEM capabilities on a realistic synthetic model clearly show that this technique is worthwhile to be advanced further. The memory and computational time estimate demonstrate the necessity of additional work on the method prior to recommending it for practical processing.Far-field sonic imaging is becoming a well-established tool for high-resolution structural imaging in the vicinity of the borehole.
