Modeling of acoustic fields, induced by the flow noise in the near-wellbore zone

We consider modeling of wellbore acoustic fields induced by the flow noise in the formation inflow zone. The influence of reservoir properties, geometry, and phase composition of fluid on acoustic field in wellbore is investigated. Using numerical modeling, we showed that these factors significantly influence the spatial-frequency pattern of spectrum, and certain frequencies of the spectrum are strongly amplified. We demonstrate various examples of reservoirs with oil and gas wells.
