Details
It is well known that seismic data is frustratingly insensitive to gas saturation, limiting our ability to distinguish residual from commercial accumulations. In this workshop, we will use real and synthetic examples to explore whether modern imaging and inversion methods are finally able to crack this longstanding geophysical challenge.
