As seismic waves travel through the earth, the visco-elasticity of the earth's medium will cause energy dissipation and waveform distortion. This phenomenon is referred to as seismic absorption or attenuation. In hydrocarbon reservoir description, seismic absorption can be used as an attribute to interpret for fluid units. In seismic data processing, this information can be used to enhance seismic data resolution by means of absorption compensation. The absorptive property is described by a quality factor, Q, which defines the energy decay and a velocity dispersion relationship. The quality...
