Seismic characterisation of coal interbed multiples in Cooper Basin, Australia
Apparent attenuation resulting from interbed multiples is conveniently expressed by Margrave’s nonstationary convolution model. A few examples of nonstationary processes are time migration, normal-moveout corrections, and ...
Signal Enhancement and Impedance Inversion for Highly Cyclically Stratified Sedimentation
In highly cyclic sedimentation with large impedance contrasts, such as coal beds, peg-leg multiples make seismic ties with primary-only synthetics difficult. If internal multiples are included in synthetic seismograms, ...
