Carbonate velocity model building is challenging due to the complex geometry and sharp velocity contrasts associated with carbonates. Full-waveform inversion (FWI), together with long offsets, wide azimuth and good low frequency data, is known to be a powerful tool to address these challenges. Unfortunately ...

Time-lapse seismic is now being used more frequently to assist reservoir development, prevent infrastructure damage or monitor geological storage. To better reveal true 4D signals while suppressing acquisition-related noise as a result of, for example, water velocity changes, source positioning errors etc., a new ...

Successful applications of full waveform inversion (FWI) to land datasets are far less numerous than marine applications, yet the development of dense, long-offset broadband acquisitions has presented promising opportunities. While challenges exist due to elastic effects, acoustic land FWI has been shown to provide ...

Spanning decades of exploration and production in the United Kingdom Continental Shelf, many programs of towed streamer data have shaped our knowledge of the Central North Sea. However, the fundamental lack of illumination and azimuth/offset coverage provided by towed streamer geometries, remains a blocker ...

The Northern North Sea is a very active area for oil and gas exploration with several commercial discoveries made over the last few years. These include the Dugong discovery on the Tampen Spur and multiple discoveries in the Greater Fram area on the Horda ...

Sophie Zurquiyah joined CGG in 2013 and was appointed CEO in 2018. The collapse in oil price,Covid-19 pandemic and energy transition have created a tough business environment during her near four-year tenure in this role, but also created opportunities. In this interview, Sophie talks ...

Executives from CGG, PGS and TGS shared how their companies are helping businesses minimize their carbon footprints by implementing CCS subsurface technologies and services.

Each year the geoscience industry creates huge volumes of documents containing a wealth of knowledge which cannot be easily queried or extracted. Key to the successful extraction and transformation of data is an understanding of the nature of the data that exists within a ...

Based on an extensive 3D modelling study utilising full-wavefield Finite-Difference modelling and Full-Waveform Inversion (FWI) we demonstrate that the TopSeis/OBN hybrid acquisition acquired from May to August 2021 in the Nordkapp basin in the Barents Sea has the potential to image salt flanks and ...
