The 4D seismic method has been increasingly applied since being introduced some four decades ago for reservoir monitoring including pressure changes and fluid replacements. At the same time, seismic...

In recent years the industry has seen a paradigm shift with the advent of Full Waveform Inversion (FWI) imaging in 3D seismic data processing projects. Fundamentally this is a fairly simple process...

Presented here is a case study where the authors developed a workflow to build a background S-wave velocity model for an existing deep-water ocean-bottom node (OBN) survey in the Gulf of Mexico.

The near-surface in the Delaware basin in the Permian is characterized by interbedded thick deposits of late Permian halite and anhydrite introducing a high velocity layered system, in addition to...

This paper shows the results of a high resolution, hybrid Ocean Bottom Node (OBN) and short offset streamer (eXtended High Resolution, XHR) acquisition, combined with an enhanced processing solution...

In this paper, the authors compute traveltime-tables for Kirchhoff depth migration using a full wave equation (acoustic, visco-acoustic, elastic, visco-elastic, etc.), which can directly use...

Among other advantages, multicomponent seismic data acquired at the sea floor facilitate the separation of up- and downgoing wavefields. These separated components can then be used to reveal an...

This paper aims to present a novel application of unsupervised machine learning (UML) to semblance-based velocity picking. Earlier methods have used UML to identify semblance maxima within a single...

This paper will discuss the many challenges in creating and processing large volumes of data and the steps associated with generating a 3D volume over a vast area.

Updated regulations for seismic surveys acquired in the Gulf of Mexico have significantly changed how large scale Ocean Bottom Node (OBN) surveys can be acquired. The primary impact of these changes...
