Three-dimensional modeling of acoustic noise in well-bore induced by the source in reservoir

We consider three-dimensional modeling of wellbore acoustic fields induced by the fluid flow noise in the reservoir. The goal is to develop highly accurate mathematical models to improve the quality of interpretation of acoustic noise logging data for oil and gas producing wells. Using the spectral element method, we simulate acoustic fields in wellbore, analyze their spatial frequency patterns and the fine structure of the resulting 3D resonance modes. In the axisymmetric case we compare the results with the previously found solution simulated by the two-dimensional finite-difference algorithm.
