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 ...

There have been many advances in natural language processing in recent years but most of the work have been focused on texts from a general domain or medicine and so datasets in the geology domain are sadly lacking. We demonstrate how existing taxonomy and ...

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 ...

While significant progress has been made in CCUS over the last five years, the industrial and financial sectors need to see how projects are being effectively de-risked. By capitalizing on the latest technology advances and the integration of multidisciplinary skills and data, geoscience has ...

This paper describes a new dense survey acquired in 2020 in the Permian Basin and aims to objectively assess the quality and benefits brought by a richer low end of the spectrum and far offsets. For this purpose, we considered several aspects, from acquisition ...
