5-Day Seismic Interferometry Course

5-Day Seismic Interferometry Course

Objective: Seismic interferometry can be defined as correlating traces together in a common shot gather (or common receiver gather) and summing the resultant correlograms over either shot or receiver indices. The main benefit is that the source and/or receiver arrays can be redatumed to be closer to the target body without knowing the velocity model. Other possible benefits include super-illumination, super-resolution, super-stacking elimination of well statics, interpolation, data extrapolation, and no need to know the velocity model or the source's excitation time or wavelet. An alternative description of seismic interferometry is that it is Berryhill's redatuming equation except the data, rather than the estimated velocity model, are used to construct the extrapolation operators. The main objective of this 5-day course is to present the key ideas of seismic interferometry and illustrate them with examples from marine data, land data, and synthetic data. MATLAB exercises will be presented that educate the user about the benefits and pitfalls of interferometric imaging. Examples will be presented that use interferometry for 2D deconvolution, data extrapolation, data, interpolation, super-stacking, and super-illumination. (Details Here).
