A slow wave in a fluid layer simulating an oil-saturated seam

A simple model of an oil-saturated layer is proposed. A slow wave propagating in a fluid layer sandwiched between two elastic half-spaces is studied. For this wave the phase and group velocities and also the horizontal and vertical components of the displacement are presented. The theoretical results are in good agreement with the experimental data obtained. Bibliography:4 titles. Translated fromZapiski Nauchnykh Seminarov POMI, Vol. 203, 1992, pp. 101–112.
