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 ...

AI capabilities are evolving and helping optimize workflows and aiding E&Ps with the vast troves of data they collect daily.

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 ...

The Gulf of Mexico (GoM) is one of the most prolific oil and gas producing provinces in the world. The Mad Dog Field, like many large deepwater fields in the GoM, is subsalt. The geometric complexity of the overlying salt causes extremely variable image ...

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 ...

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 ...

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 ...
