Time-lapse (4D) inversions deal with changes in seismic amplitudes and travel-times. This analysis is performed on migrated seismic images, which represent the spatial and time-lapse variability of the medium’s reflectivity. 4D reservoir analysis methods such as inversion and warping need to follow the structure ...

Using pre-stack model-based inversion we will analyze the impact of marine seismic acquisition and processing on our ability to predict elastic parameters.

We demonstrate how we unlocked the potential of one of the last underexplored regions of the South Atlantic margin through smart seismic acquisition, processing technology and close collaboration.

For seismic exploration (i.e. reservoir geophysics), retrieval of body waves appears promising, especially at low frequencies (below 3 Hz) where seismic vibrators reach a limit. These low frequencies are of interest for velocity model building (Baeten et al. 2013) and for broadband seismic inversion ...

The use of broadband data in reservoir characterization has proven advantages. However, the whole workflow should be reviewed and renewed in order to get all the advantages of broadband data.

Reliable low frequency content and phase alignment are critical for broadband seismic inversion and the prediction of reservoir properties. However, currently there is a lack of tools for ultra-low frequency (less than 5 Hz) quality and phase assessment. A focusing metric in the impedance ...

In an increasingly complex and challenging environment, CGG is building effective links between academia and industry and utilising new techniques to enhance hydrocarbon exploration success in a world where oil prices are highly volatile. In this environment there is increasing focus on risk reduction ...

Recently there has been renewed interest in the hydrocarbon potential of the Perth Basin in Western Australia. Recent discoveries of gas have shown that there is a working hydrocarbon system within at least the northern and central parts of the basin. In most parts ...

The deepwater Gabon South Salt basin represents one of the last underexplored regions of the West African continental margin. A new 25,000-sq km (9,653-sq mi) broadband 3D seismic survey was recently acquired in the basin as part of an integrated eoscience program to support ...
