Greater Johan Castberg area, Barents Sea: Outstanding near-offset coverage and long-offset FWI
CGG, together with TGS, recently acquired a multi-client TopSeis™ 3D seismic survey in the Barents Sea. The survey, known as “Greater Castberg” was acquired and imaged using the latest advances from CGG's proprietary TopSeis solution. The latest advances include a wide distribution of five ...
Advanced reprocessing of legacy seismic data offshore Peru
Advanced reprocessing of legacy seismic data offshore Peru
Paper designed to focus on new technology - our specific focus is on the use of modern processing sequences applied to 2D legacy data in Peru (GeoSpec). There are links drawn from previous geological study of the area.
An integrated geoscience workflow to improve unconventional play assessment – an example from the SCOOP/STACK, Oklahoma
An integrated geoscience workflow to improve unconventional play assessment – an example from the SCOOP/STACK, Oklahoma
This article highlights some important outcomes from an integrated study in the Anadarko Basin. Newly generated data is presented and discussed across the study area. The main aspects discussed here focus on 1) basin evolution, which has played an important role in source maturity ...
Geology-guided pore space quantification for carbonate rocks
Geology-guided pore space quantification for carbonate rocks
The heterogeneity in geological properties of carbonate rocks makes their acoustical behaviour more difficult to model and predict than siliciclastics. This uncertainty in prediction normally is attributed to their pore structure complexity and heterogeneity. Pore structure in carbonate is a result of the place ...
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 ...
Fluid detection in carbonate rocks by integrating well logs and seismic attributes
Fluid detection in carbonate rocks by integrating well logs and seismic attributes
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 ...
Norway: New play models for Patch Bank Ridge, east of Utsira High
Norway: New play models for Patch Bank Ridge, east of Utsira High
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 ...
