Workshop 11
Exploring the Limits of Gas Saturation Measurement Using Seismic Data Monday, June 8th|
Convenors
- Alistair Crosby (BP)
- Rodney Johnston (BP)
- Mark Chapman – (University of Edinburgh)
- Gary Hampson (DUG)
Description
It is well-known that seismic data is frustratingly insensitive to gas saturation (“a little gas goes a long way”), and this limits our ability to distinguish residual from commercial accumulations, particularly in exploration settings where well information is sparse or absent. In this workshop, we will explore the extent to which conventional imaging and modern inversion-based methods (such as multiparameter FWI) can crack this most longstanding of geophysical challenges. A focus will be the findings of a recent “gas saturation acceleration challenge”, in which participants attempted to distinguish between commercial and non-commercial (residual) gas saturations in both field and realistic synthetic datasets – but all novel contributions on the theme will be welcomed.
Sub-Topics that will be covered in the workshop:
- Sensitivity of viscoelastic parameters to gas saturation in different geological settings – theoretical and laboratory view
- Interim results from the recent “gas saturation acceleration challenge” (field and realistic synthetic datasets)
- Other compelling field and synthetic data examples
Participant Profile
Commercial and academic participants in the bp “Gas saturation acceleration challenge” as well as anyone with an interest in how to distinguish between commercial and non-commercial gas accumulations using seismic data.
