Inversion of 4D seismic data for production facies

Rapid and accurate characterization of time-lapse seismic data is important to enable operational adjustments to be made and provide a guide for future drilling. A facies-based Bayesian inversion offers some advantages over traditional simultaneous prestack inversion, primarily a... Read More.


Optimisation of Pre-stack Scaling Prior to Seismic Inversion

When interpreting seismic reflection data, a common problem is the uncertainty in the representation of a reflecting interface — is it a peak, zero crossing or trough? This uncertainty itself leads to different qualitative interpretations by different geoscientists and ulti... Read More.


Density from Seismic Inversion

A pre-stack simultaneous inversion in the Cooper-Eromanga Basin has produced very good predictions for all elastic properties: acoustic impedance (AI), shear impedance (SI) and density (Rho). The predicted relative elastic properties show very high correlations (>80%) with wel... Read More.


Seismic inversion of a carbonate buildup: A case study

The information within seismic data is band limited and angle limited. Together with the particular physics and geology of carbonate rocks, this imposes limitations on how accurately we can predict the presence of hydrocarbons in carbonates, map the top carbonate, and characteriz... Read More.
