Côte d'Ivoire Tano Basin offers significant exploration opportunity, with multiple recent discoveries including Bubale-1x, Murene-South-1x within Upper Cretaceous deepwater slope channels / fan systems, and Baleine, a shelf-edge carbonate discovery. The extensive play diversity and prospectivity is highlighted by a new 16,000 sqkm high-resolution ...

In recent years, full-waveform inversion (FWI) has become a cornerstone of velocity model building in seismic processing. The technique has repeatedly proven its effectiveness in delivering significantly more accurate velocity models, resulting in improved migration images across a wide range of acquisition configurations and ...

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 ...

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 ...

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 ...

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 ...

Inspired by the successes of sparse ocean bottom nodes (OBN) programs in recent years, especially the industry's first long-offset, low-frequency (LOLF) sparse OBN survey using the Tuned Pulse Source (TPS) as the seismic source (Merritt et al., 2024), Viridien acquired Laconia OBN, its vast ...
