Abstract

The paper presents a solution to the forward acoustic logging problem for a multi-pole acoustic radiator located in a non-cylindrical well off its axis. The modelling investigates how the non-cylindrical well geometry and the displacement of the radiator from the well axis influence the parameters of the measured elastic waves.
