NVGS, a recently acquired southward extension of the NVG survey in the northern Norwegian North Sea, is a high-quality broadband seismic data set, which reveals detailed stratigraphy from the Permian Salt to the Quaternary section for stratigraphic and lithological interpretation. In the deeper parts ...

This paper presents a detailed and integrated methodology and case study for building a 3D geological model to characterize a Lower Cretaceous reservoir for a field located offshore Abu Dhabi.

A desktop study using the recently acquired 2D seismic data on the prospectivity over the oceanic crust, in ultra-deep water Gabon.

Exploration on the African continent has traditionally been concentrated in prolific basins on the Sub-Saharan Western margin, in detriment to the East. Proven prolific basins, existing infrastructure, favourable and progressively transparent regulation; along with the analysis of prospective conjugate basins of Brazil are just ...

As the key step in subsalt imaging, conventional salt model building has typically relied on manual interpretation of the salt geometry, which proves to be difficult for resolving complex salt models. As a result, subsalt imaging has been approaching a plateau in the last ...

Areas with complex overburdens pose a major challenge for seismic imaging of deep targets. Reduced illumination can compromise velocity estimation and the image at the target level. A solution to this problem is given by ocean bottom node (OBN) acquisitions. They provide increased illumination ...

Santos Basin has become one of the most prospective oil provinces in the world. Due to the geological complexity, OBN acquisition has emerged as an imaging solution. It provides the full-azimuth and long-offset illumination FWI needs to realize its potential. Given the right data ...

Stampede field is a faulted subsalt four-way reservoir in Green Canyon, Gulf of Mexico. Imaging for part of the field has remained challenging due to interference from the complex overburden, which carries large velocity errors and creates non-uniform illumination for the subsalt. Before correcting ...
