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)...

Obtaining high-quality seismic images from Distributed Acoustic Sensing Vertical Seismic Profile (DAS VSP) data is challenging due to its limited subsurface spatial sampling and suboptimal data...

In this paper, the authors propose an elastic dynamic matching FWI (EDMFWI) as an extension of the acoustic algorithm. With the successful applications to variety of datasets, it demonstrates the...

In deep water Ocean Bottom Node (OBN) surveys, after wavefield separation, the downgoing dataset is most useful due to its superior illumination compared to the upgoing wavefield. However, the...

In this paper, the authors present FWI images from the recent FWI model and combine these with AVO intercept volumes to create a new attribute that can act as a screening tool to help understand...
