In shallow water environments, near surface reflectivity information is poorly recorded with 3-D towed streamer acquisition geometries. Therefore, the missing information must be reconstructed in the...

When considering shallow water towed streamer data, developing an accurate velocity model using primary reflections alone is challenging and often only allows an average velocity of the near surface...

Compensating for water velocity variations remains a key challenge in seismic data processing, where the water velocity varies over time. In a 3D seismic survey, adjacent sail lines are recorded at...

A case study was carried out over the Valemon and Kvitebjorn Fields, where a high fidelity velocity model was built to solve the complex velocity variations in the overburden. A shallow channel...

Multi-component towed streamer data allow for separation of the up-going and down-going wavefields and, thus, sea-surface independent removal of the receiver side ghost. To achieve deghosting of...

Future time-lapse broadband surveys should provide better reservoir monitoring resolution by extending the 4D signal bandwidth. In this paper, we will review the consequence of extending the signal...

This paper proposes a new trace up-sampling method for seismic data. The method is based on building a local time-space model of the seismic data following some physical assumptions about its...

New streamer technology has provided a step change in seismic data quality. The increase of the natural frequency content of seismic data as well as the ability to accurately separate seismic data...

Upon successful installation and acquisition of 4D data from the Jubarte pilot PRM system, we would like to share some of the lessons learned from the Jubarte experience. Discussion includes the...

A depth migration method, that uses primaries and all orders of multiples, has been adapted to produce extended 3D and 4D images in the context of seabed acquisition. The technology has been...
