The objectives of this paper are to discuss the successes and challenges of applying high frequency DM FWI to OBN data and the alternative QC methods required as the industry moves towards higher...

Ocean bottom node (OBN) data in a shallow water environment can be contaminated by near surface elastic effects such as guided waves. The presence of these waves may present a challenge for acoustic...

Many regulatory bodies (as well as sound engineering practice) require a shallow high-resolution survey prior to drilling or adding infrastructure. While there are acquisition methods specifically...

With more and more marine seismic surveys utilizing Full Waveform Inversion for high quality velocity models it will be beneficial to generate additional low frequency energy beyond standard marine...

Effective attenuation of strong ground roll while preserving the signal is still a challenging task for land seismic data processing. Eigenimage filtering, either in time domain or frequency domain,...

Efficient acquisition of large-scale, azimuth-rich ocean bottom node (OBN) data, with long offsets and high fold is now a reality. Such data provide an opportunity to apply advanced model building...

The Faroe Shetland Basin area located to the West of the Shetland Islands is typified by complex structural features with highly variable velocities, often with sharp contrasts.

Ocean Bottom Node (OBN) data can be acquired using blended acquisition or simultaneous shooting that allows temporal overlap among different sources. A higher blending ratio can help reduce the...

In ocean bottom seismic data, vertical components are frequently contaminated by converted shear waves due to the scattering in the shallow seabed. Proper removal of this energy is an important step...

Ocean Bottom Node (OBN) acquisition provides ultralong offset and full-azimuth (FAZ) illumination for better model building and imaging. A blended-source, sparse-node deep water OBN survey can...
