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 ...

A case study of Oligocene-Miocene sediments in East Java Basin, Indonesia. The work look into the depositional setting and paleogeography of subsurface by removing the struture in 3D seismic. The result have been correlated with regional geology and outcrop analog. The work is done ...

The success of any broadband survey is dependent upon the accuracy with which acquisition and environmental factors are compensated for in processing. Such compensation ideally involves directional source designature and deghosting along with receiver deghosting. Traditionally, receiver deghosting is applied in the shot domain ...

Making informed field development decisions requires taking uncertainty into account. Geostatistical inversion is a key technology for quantifying uncertainties using available seismic and well data. However, the common practice, consisting of choosing the "best possible" parameters, results in unrealistically small uncertainty estimates. In this ...

The size and complexity of the mega gas clouds in offshore Brunei pose severe imaging problems to the structures underneath. We present a comprehensive technical package to tackle the complex wave propagation and anelastic energy losses associated with these gas clouds. We started by ...
