Investigation of and correction for waveform changes arising from NMO stretch
NMO-stretch distorts seismic frequency content significantly depending on depths of the target reservoir and offset locations. It causes poor resolution on CMP-stacked sections for image processing, and also creates ...
Application of Constrained Least-Squares Spectral Analysis
Constrained Least-Squares Spectral Analysis (CLSSA) is applied to seismic data for (1) stratigraphic layer thickness estimation, (2) stratigraphic visualization, and (3) Hydrocarbon indication. Results obtained from these ...
