The next-generation seismic reservoir characterisation technology

Page last modified

April 11 2024

Wave-Equation Based Amplitude Versus Offset (WEB-AVO) translates migrated seismic data into elastic reservoir models using a unique physical data model. It is the only AVO technology that properly accounts for multiples, mode conversions and transmission effects and in combination with its innovative parameterisation, it represents the high-tech seismic solution for risk reduction and return maximisation of Exploration & Production, geothermal but also CO2 storage projects.

Pros & Limitations

Three times more sensitive to hydrocarbon saturation and lithology changes when compared to conventional solutions

Most realistic AVO data model

Unique parameterisation, solving for compressibility and shear compliance

Computationally more expensive
