For subsurface commercial ventures or environmental projects that rely on maps of faulted horizons, accurate maps are fundamental. Fault topology provides an ideal tool for analysis of connectivity of fault systems. The data required to undertake the analysis is straightforward to extract from fault ...

Ocean Bottom Node acquisition is known to improve seismic velocity model building and imaging, especially for deep and complex targets. Due to cost considerations, OBN surveys are typically only acquired around the production field, using a relatively dense receiver grid. At the exploration phase ...

We evaluate how two-dimensional (2D) seismic and controlled source electromagnetic (CSEM) imaging, both vintage and modern, might help improve geological understanding of, and exploration for, SMS deposits along part of the Mohns Ridge segment of the ultraslow-spreading Arctic Mid-Ocean Ridge. Mohns Ridge has been ...

The Atlantis Field has gone through more than two decades of continuous seismic imaging efforts, during which time many innovative technologies were incubated, the most recent one being the successful application of full-waveform inversion (FWI) in salt environments. This technique led to a significant ...

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 ...
