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 ...

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 ...

In this case study, we present results from the first ocean bottom node (OBN) based 4D imaging at the Liza field, offshore Guyana. With two nominally repeated OBN surveys acquired within less than a year, we initially employed a parallel 3D processing flow to ...

A comprehensive assessment of geomechanical risks is essential for the success of geological carbon storage. Although the relationship between injection-induced pore pressure changes and rock failure is broadly understood in poromechanics, the challenge of characterizing and managing geomechanical hazards associated with subsurface CO₂ injection ...

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 ...

New long-offset, low-frequency (LOLF) OBN acquired using the innovative TPS low-frequency source provides transformational imaging of the subsalt geology in the complex and inboard, minibasin domain of the central Gulf of Mexico (GOM). The role of low-velocity (LV) shale bodies in the deformation, which ...
