In this paper a comparison of deterministic and geostatistical inversion approaches to reservoir characterization of a complex gas saturated clastic reservoir with thin coal beds will be discussed. This type of reservoir is characterized by high acoustic contrasts which cause challenges for inversion techniques ...

Water column statics caused by tidal variation and water velocity change during seismic surveys is one major source of noise in marine 4D projects. Correction of this statics effect is a key step in any marine 4D processing. Applying water column statics correction requires ...

Surface wave inversion (SWI) for S-wave velocity plays an important role in near surface characterization and PS-wave velocity model building for depth migration. A hybrid approach is proposed to reduce non-linearity for multi-modal inversion without a-priori identification of higher order modes. This method is ...

The compensation of absorption loss inside the imaging process using attenuation models estimated by Q-tomography is now widely accepted and used in the industry. This technology becomes even more important in the case of a complex dataset. For the Martin Linge field, characterized by ...

An automated and real-time field PSTM system, called TeraMig, was applied during the acquisition of a land 3D WAZ survey for PDO. The system was used to migrate one million vibrated points (around 10 billion traces) and was able to generate a real-time field ...

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 ...
