On the basis of known relationships between various elastic moduli
and porosity in a porous medium and of various parameters from well-logs,
the reflection coefficient for normal incidence of P-waves is compared
to that of S-waves. If pores contain gas, the reflection coefficient
in S is much smaller than that of P but shows large differences for
different gas concentration in one of the two layers while the reflection
coefficient in P is insensitive to the gas concentration. It is found
that the ratio of the two reflection coefficients provides a powerful
tool for discriminating between layers of different degrees of gas
concentration and for the extension of the sensitivity of the bright-spot
technique to greater depths.
