[2014-09-09] Joint inversion of time-lapse seismic datasets
Joint full-waveform inversion of time-lapse seismic datasets with model-difference regularization is a promising new technique for identifying production-induced changes within hydrocarbon reservoirs and in the overburden. The proposed technique achieves robust inversion of velocity changes in the presence of challenging survey repeatability issues.
