Abstract
A method for determining the lithology of subterranean structures based on attenuation of wave energy is disclosed which features a wave model based on a two-way solution to the wave equation rather than one-way solutions previously proposed. Rather than measuring amplitude of the wave as a function of its attenuation, energy flux density is measured which provides a two-way wave solution. In a preferred embodiment, pressure gradient measuring transducers are used to measure the energy flux density.
