Distributed Acoustic Sensing (DAS) is gaining increased attention in the Carbon Capture and Storage (CCS) industry as a feasible cost-effective method for subsurface imaging and monitoring. This study examines the processing and imaging challenges of surface-acquired DAS data in the North Sea with a ...

Junior Potgieter, Global Strategy Head, Minerals & Mining, Viridien, explains how AI and other advanced tech is transforming the work of explorers.

Carbon storage licensing on the Norwegian Continental Shelf has gained momentum, highlighting its role in the energy transition. Legacy seismic data, originally acquired for oil and gas exploration, is a valuable asset for assessing carbon storage reservoir potential. Maximising the value of this data ...

Viridien has conducted a test of inversion techniques to evaluate which methods prove useful over large areas of interest. Both Extended Elastic Impedance coloured inversion (EEI-CI) and Deterministic Elastic Inversion (DEI) were evaluated as exploration screening tools for the Lower Cretaceous Agat play on ...

Reaching Europe’s net‑zero ambitions requires rapid, scalable deployment of carbon capture and storage (CCS). This white paper presents Viridien’s integrated screening workflow for identifying, ranking, and prioritizing geological CO₂ storage opportunities across continental Europe. Using a globally consistent digital geological database and a multi‑scale ...

ELEM Biotech streamlines cardiac simulations by 40% with Viridien HPC & Cloud Solutions

Structural distortions are frequently encountered in Abu Dhabi area with significant velocity heterogeneity and complex geological features. Due to the unique challenges, FWI often struggled to accurately resolve small-scale distortions. The hard seabed and ultra shallow water environments lead to significant noise that destabilize ...

Imaging deep targets underneath highly heterogeneous overburden using data from non-ideal acquisition is always challenging. In Block SC38, offshore Philippines, the seismic energy propagation is disrupted by a complex volcanic system in the overburden, leading to washed-out imaging beneath the volcano. The absence of ...

Many fields in the Brazilian pre-salt have been historically imaged with narrow-azimuth towed-streamer (NATS) data and only recently have been surveyed with ocean bottom nodes (OBN). Some cases of time-lapse 4D seismic monitoring are limited to hybrid pairs of data, where a NATS baseline ...
