Time-lapse (4D) seismic surveys are devised to detect subsurface changes resulting from hydrocarbon production and fluid injection. Full-waveform inversion (FWI) of time-lapse seismic data has been reported to provide high-resolution estimates of 4D changes. However, successful applications of 4D FWI on field data have ...

The western part of the Gulf of Mexico (WGOM) is often characterized by large and complex salt and shale bodies, making it notoriously challenging to image deep subsalt targets, especially with only wide-azimuth towed-streamer (WATS) data available. In 2018, BHP acquired a large-scale sparse ...

The 4D global inversion workflow is a multistage process that includes seismic data preconditioning, wavelet estimation, low-frequency model building, 3D inversion, and finally a 4D global inversion. In this work, focusing on a post-salt turbidite reservoir in the Campos Basin, offshore Brazil, we show ...

Exploration activity in the Barents Sea has fluctuated considerably over the last 40 years, in line with the price of oil and general industry optimism. Today’s high level of activity focused on ongoing and planned field developments and production may spur further exploration as ...

At first glance, the Western Indian Ocean region may look like a barren oceanic crust with little potential, but there is tantalising evidence to suggest otherwise. CGG geoscientists have been sifting through the evidence to re-evaluate opportunities offshore East Africa and in the Western ...

Overview of carbonates short courses for Nov, Dec 2021.

Deep neural networks are used to characterize the porosity and permeability of the Dogger formation north-east of Paris, France, that already hosts a number of geothermal plants and is set to become even more important with the transition toward renewable energies. Due to the ...
