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.
The Faroe Shetland Basin area located to the West of the Shetland Islands is typified by complex structural features with highly variable velocities,.
Ocean Bottom Node (OBN) data can be acquired using blended acquisition or simultaneous shooting that allows temporal overlap among different sources. A.
In ocean bottom seismic data, vertical components are frequently contaminated by converted shear waves due to the scattering in the shallow seabed. Proper.
Ocean Bottom Node (OBN) acquisition provides ultralong offset and full-azimuth (FAZ) illumination for better model building and imaging. A blended-source,.
Iterative data-domain least-squares migration can overcome acquisition limitations and recover the reflectivity for desired amplitudes and resolutions..
Least-squares imaging of primary reflection can overcome acquisition limitations and recover the reflectivity for desired amplitudes and resolutions (Wang.
One of the advantages of ocean bottom seismic data is combining hydrophone and vertical geophone data for ghost reflection attenuation. However, when the.
Due to inherent benefits such as ultra-long offset, full azimuth (FAZ) illumination and low-frequency availability, a large multi-client sparse-node.
We propose a multi-channel dynamic matching full-waveform inversion (DMFWI) for a high-resolution velocity-model update, which focuses on solving.
Imaging artifacts caused by strong internal multiples can interfere with primary images, affecting structural interpretation and amplitude analysis. In.
When a seismic wave propagates in the subsurface of the earth, its energy can be attenuated. This has a negative influence on both the amplitude and the.
