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 corpus of files. For large datasets, it is time-consuming to manually open and review each document in turn. Therefore, in this article, we discuss how machine learning is used at CGG to classify documents in our automated pipeline and reduce project times significantly.

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 sedimentary details, given an accurate initial model in the shallow and a carefully designed deblending and FWI workflow. As a part of this we demonstrate that the large offsets and multi-azimuth recorded by the ocean bottom nodes are crucial to image the complex salt diapirism in the area including the steeply dipping flanks.

Sercel has announced that its state-of-the-art WiNG land acquisition nodes are making a key contribution to a major mining exploration program in Zambia’s Katangan copper-bearing basin.

Survey design comparison regarding seismic reservoir characterization objectives: a case study from South Tunisia L. Michou, L. Michel, P. Herrmann, T. Coleou, P.Feugere, J.L. Formento The objective of this onshore survey designs’ comparison case study is to highlight the impact of the acquisition trace density on seismic reservoir characterization in order to optimize acquisition geometries. Structural, AVO and AVAz seismic reservoir attributes and QCs from 4 seismic surveys over the same area, the Jebel Grouz South Tunisian field, are compared. Results highlight the added value of the acquisition trace density in comparison to the source strength or the source and receiver proportion, especially for elastic and anisotropic seismic reservoir characterizations.
