Since the discovery of pre-salt oil fields offshore Brazil two decades ago, the Santos Basin has transitioned from an exploratory to a development phase. This requires a more comprehensive understanding of the reservoir physical properties. This study aims to demonstrate, on one of the ...

Automated grain segmentation and mineral classification in rock thin sections
Automated grain segmentation and mineral classification in rock thin sections
Traditional petrographic analysis of rock thin sections is time consuming, it is potentially subjective, may suffer from operator bias, and the results are not necessarily representative of the bulk rock sample. The challenge to automation of petrographic description is the complexity that is inherent ...
Characterizing North Sea chalk with high-resolution elastic full-waveform inversion
Characterizing North Sea chalk with high-resolution elastic full-waveform inversion
Full-waveform inversion (FWI) is a well-established technology for building high-resolution velocity models over complex areas. Conventional industry implementations of FWI typically use the acoustic approximation, which can break down in the presence of strong velocity contrasts where elastic effects in the recorded data cannot ...
Correcting Image Distortion Below Complex Gas with Dynamic Resolution Q-TLFWI in the Andaman Sea, Offshore Indonesia
Correcting Image Distortion Below Complex Gas with Dynamic Resolution Q-TLFWI in the Andaman Sea, Offshore Indonesia
Significant subsurface imaging distortions are frequently encountered in intricate faulted structures below substantial gas accumulations in the overburden. The primary difficulty arises from the absorption of seismic energy by gas bodies, and the presence of complex velocity heterogeneities. In these settings, visco-acoustic Time-lag Full ...
Deepwater Zambezi Delta, Mozambique-exploring a frontier basin using high resolution imaging
Deepwater Zambezi Delta, Mozambique-exploring a frontier basin using high resolution imaging
This study demonstrates how a high-end 3D seismic survey can generate new insights within a frontier basin such as the Deepwater Zambezi Delta in Mozambique and uncover hidden facets of basin evolution. Observations from high-resolution seismic imaging integrated with potential fields data have helped ...
Angle-restricted FWI for shallow reservoir characterization
Angle-restricted FWI for shallow reservoir characterization
In the Barents Sea, bright amplitudes on seismic data below the Base Quaternary indicate the presence of hydrocarbon reservoirs. To allow characterization and quantitative interpretation of these potential reservoirs, analysis of amplitude versus reflection angle (AVA) information is crucial. Even with the availability of ...
Recent discoveries in Namibia’s Orange Basin have raised industry expectations that a similar level of success could be replicated in its conjugate margin, Uruguay. Still considered as a frontier basin, the Uruguay deepwater has similar geological elements at basin scale and unique aspects at ...

Karim Lassel interviewed by Oil Review Middle East about Viridien’s activity in the MENA region
To coincide with ADIPEC 2024 Karim Lassel discusses Viridien’s bold rebrand and its commitment to drive innovation for the energy industry.
Côte d’Ivoire - The new West African exploration hotspot
Côte d’Ivoire - The new West African exploration hotspot
The play-opening giant discoveries of Baleine and Murene-1 (Calao) offshore Tano Basin have reinvigorated exploration in the Equatorial margin of Africa. The basin is geologically complex and has proven its unparalleled hydrocarbon potential. To further explore this basin, there is a need for high-end ...
