It has been well documented that the pre-stack seismic attributes can be an efficient tool for hydrocarbon exploration and pore fluid detection using techniques like Amplitude Versus Offset (AVO) analysis. These studies mainly focus on siliciclastics rather than carbonates as fluid effects in carbonate ...

We address the problem of creating low frequency models for AVO inversions, investigating two workflows, neither of which involve well log interpolation. The first workflow creates a constant but structurally-compliant low frequncy model from averages over available logs. Facies analysis is done from the ...

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.

Interbed multiples cause artifacts in subsurface images because they are incorrectly migrated when using standard primary-based migration algorithms. While surface-related-multiple-elimination has been well established as a standard step in seismic processing, the usage of interbed multiple attenuation (IMA) remains low due to various practical ...

Geophysical imaging in the foothills environment is typically hampered by complex structure, and the high cost of data acquisition in poorly accessible, rugged topography. Seismic imaging is particularly difficult due to poor signal penetration, steeply dipping structures and irregular data coverage. The use of ...

Direct wave arrivals are the most robust signals to determine velocity and consequently they have been used for almost a century in hydrocarbon exploration. The reason is simple as the arrival time is explicitly available. In order to acquire these direct arrivals in a ...
