Acting as a technology-agnostic, standards-based data platform, the OSDU has reduced energy data silos and provided the capability for applications developers to build new solutions and data ingestion services. The current OSDU schemas are primarily created to store file metadata to allow users to ...

The increasing focus on de-risking near-field exploration in the Northern Viking Graben area demands data with improved imaging. This has led to CGG initiating a new multi-year acquisition programme to acquire east–west triple-source multi-sensor seismic data over a 24,000 km2 area, adding a second ...

The northern North Sea is a very active oil and gas exploration region, where several commercial discoveries have been made over recent years. The Late Jurassic sands are one of the major reservoir plays in the Northern Viking Graben. In recent years, the Late ...

Full-waveform inversion (FWI) has become the centerpiece of velocity model building (VMB) in seismic processing in recent years. It has proven to significantly improve the velocity model, and thus the migration image, for different acquisition types and different geologic settings, including very complex environments ...

Although the resolution of a seismic image is ultimately bound by the spatial and temporal sampling of the acquired seismic data, the seismic images obtained through conventional imaging methods normally fall far short of this limit. Conventional seismic imaging methods take a piecemeal approach ...

Companies that have worked in the oil and gas industry for many decades have built up a valuable and detailed understanding of the Earth and its subsurface. One such company is CGG, a global geoscience technology and HPC leader that has been collecting and ...

Applications of full-waveform inversion (FWI) to land data have proven much more challenging than to marine data. The difficulties are linked to a lower signal-to-noise ratio but also to a greater influ-ence of elastic wave phenomena in these data sets, especially those characterized by ...

Fizz gas detection is a critical step in field development as it is often difficult to differentiate it from commercial gas in reservoirs on acquired seismic data. In a shallow reservoir context, it is theoretically possible to observe a fizz gas effect through a ...

The Haugaland High, in the Norwegian North Sea, consists of a layered overburden of sub-horizontal sediments of almost 2km thick which sits on the Cretaceous Chalk. The background velocity regime of these top layers has a low vertical gradient down to the Chalk interface ...
