Abstract
Summary
We analyze response of vertical cylindrical structures embedded in horizontally stratified media. Both the cylinders and the host media are liquid. Diameter of the cylinders is less than or approximately equal to the dominating wavelength of the signal, which represents investigation of some boreholes and natural pipes using conventional seismic exploration. We model the data with the spectral element algorithm and benchmark the method against a precise semi-analytical solution. The results show that the spectral element algorithm is a reliable method for modelling such a structure and that even thin cylinders can produce strong scattered waves visible on the recording.
