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 ...

‘Risk: The potential for adverse consequences for human or ecological systems, recognising the diversity of values and objectives associated with such systems.’ This widely used definition both clarifies and clouds how environmental scientists can discern and address risk. While it provides a broad basis ...

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 ...

The development of time-lag FWI (TLFWI) in recent years has enabled the use of the full wavefield (primary reflection, multiple, ghost, and diving waves) in inversion. With this advance it is now possible to include ever more detail in the velocity model, ultimately reaching ...

We present the main results of a tailored velocity model building workflow on a recent broadband survey from North Kuwait. Depth imaging in Kuwait presents several challenges, including the need to capture the strong velocity variations of a complex near surface that generates long ...
