Reflection of plane waves at boundaries of a liquid filled poroelastic half-space
چکیده انگلیسی
Solution for Biot's dynamical equation are analyzed for reflection of waves at free permeable and impermeable boundaries and rigid permeable and impermeable boundaries along with partitioning of energy. Reflection of waves at such boundaries are useful to seismologist and geophysicists. Variation of reflection coefficients with angle of incidence is used to detect lateral changes in elastic properties of reservoir rocks. Reflection coefficients and Square root of energy ratios as a function of angle of incidence are plotted for kerosene-saturated sandstone and water-saturated sandstone to study the effect of the presence of kerosene over water in half-space. It is found that the mass coupling parameter or interacting parameter or overlapping parameter between solid and liquid plays a significant role in generating the reflected slow dilatational wave. In general, rigid boundary behaves as an energy attenuator.
