The Santos Basin has proven to be a highly prolific basin over the past few decades, with extensive exploration activities leading to the drilling and production of numerous wells. The Santos Sul 3D...

In this paper, we present an innovative node design and deployment method that challenges the coupling paradigm. We have designed and tested an autonomous seabed recording system, but instead of...

In recent years, there has been an increased interest for multi-parameter Full Waveform Inversion (MP-FWI) within the seismic industry. This paper revisits the motivation for this approach and...

Exploration is usually performed in a phased approach, regional 2D is initially acquired with very sparse line spacings (20-50 km), this is then followed by a period of densification over specific...

This extensive study highlights the significant remaining pre-salt and post-salt potential in an open acreage area within the Santos Basin, Brazil's largest producing basin. By utilizing a...

High-dimensional (3D) FKxKy inversion is believed to enhance sparsity in the transformed domain, leading to improved deblending performance for simultaneous source data. While this approach has been...

One of the most significant improvements in model building and seismic imaging has been the incorporation of elastic wave propagation in full waveform inversion. We have extended Dynamic Matching...

Ocean Bottom Node (OBN) seismic acquisition offers rich azimuthal coverage and long offsets, which are valuable for velocity model building. Despite the better sampling of the wavefield, OBN can...
