We present a method of calculation to simulate the propagation of acoustic and elastic
waves generated by a borehole source embedded in a layered medium. The method is
formulated as a boundary element technique where the Green's functions are calculated
by the discrete wavenumber method. The restrictive assumptions are that the borehole
is cylindrical and that its axis runs normal to the layer interfaces. The method is used
to generate synthetic acoustic logs and to investigate the wavefield radiated into the
formation. The simulations considered display the Stoneley wave reflections at the bed
boundaries and show the importance of the diffraction which takes place where the
borehole wall intersects the layer interfaces.
