The development of carbon capture and storage (CCS) relies heavily on high-resolution seismic images to characterize both the geological framework of the storage site and its overburden. In this...

In marine ocean bottom node (OBN) processing, removing the effects of water velocity variation and correcting for node positions and clock-drifts reduce statics in the data. Clock-drift for...

The authors discuss the initial results of a groundbreaking 3D Ultra High Resolution Seismic (UHRS) survey utilizing a P-Cable system. The survey was initiated in the summer of 2023, offshore USA,...

The authors describe how a simultaneous velocity and angle-dependent reflectivity inversion workflow (Ultima) can provide accurate and high-resolution attributes that could help derisk frontier...

Noise is an ongoing issue in seismic processing and our capability to successfully process ocean bottom node data relies on our capability to successfully attenuate the presence of shear wave noise...

Amplitudes recorded by seismic receivers are usually clipped when the signal level exceeds the maximum signal that can be safely recorded by the instrument. Clipping leads to spectral leakage of...

Acoustic FWI has been widely applied in seismic work programs. The normal derivative of the FWI velocity model, which is known as the FWI Image, has been shown to provide a highly interpretable...

Acquisition of ocean bottom node (OBN) data in the vicinity of field infrastructure and concurrent rig activity, drilling, and adjacent seismic operations is challenging and requires careful planning...

Seismic velocity models derived via ray-based tomography and full waveform inversion (FWI) are typically non-unique, as the observed data may be explained by many possible models. Constraints may...

Sparse OBN acquisition can provide an efficient cost-effective method for acquiring seismic data over Carbon, Capture and Storage (CCS) sites. The authors demonstrate how using the full wavefield (P)...
