We present AI-drive workflow for automatic interpretation of large seismic volumes. The workflow is applied to an offshore Abu Dhabi area of 15000 km2. First, we show the fault detection results for the low-magnitude faults of strike-slip type by the fine-tuning of the DNN.

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

To coincide with ADIPEC 2024 Karim Lassel discusses Viridien’s bold rebrand and its commitment to drive innovation for the energy industry.
