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 ...
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 ...
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 ...
Ten years ago, CGG launched a project to develop a new concept of marine vibrator (MV) technology. We present our work, concluding with the successful acquisition of a seismic image using an ocean-bottom-node 2D survey
A new broadband Wide-Azimuth Towed-Streamer (WATS) survey was acquired in a shallow water region of offshore China to better resolve reservoir compartments. Two side boats were added as additional source boats to form the WATS acquisition geometry to resolve the shortcomings of narrow-azimuth acquisition ...
