High-quality subsurface imaging, especially of the shallow stratigraphic section, is critical to the success of CO₂ storage projects. In 2014-2018, Viridien began acquiring a regional broadband 3D seismic survey in the Northern Viking Graben (NVG). This regional dataset covers the Horda Platform in the north and Stord basin in the south, as seen in Figure 1 below. This dataset has been reimaged with Viridien’s latest proprietary technologies through continuous development, as industry demand for higher-quality data has grown. The newly reimaged NVG data (see map) reveals potential opportunities in semi-open aquifers with substantial storage capacity in the Stord Basin, where suitable reservoirs and seals may enable efficient injection and trapping of CO₂.
The Gulf of America is a vital part of US energy infrastructure, with its future increasingly dependent on new seismic technologies to tackle complex geology. As exploration advances into salt-dominated regions, operators are relying on advanced imaging and novel acquisition technologies to better map subsurface formations, improving visibility beneath salt layers and deepwater sediments that previously hid critical structures.
Modern Super-Regional profiles observing an entire margin are often difficult to procure as the emphasis in seismic acquisition is becoming increasingly focused on smaller-scale high-definition 3D volumes. In margins where the expected success has not yet been realised, these large regional profiles can be particularly insightful. They offer new perspectives on petroleum system–controlling features that have an impact at scales far larger than can be resolved when examining a more localized, prospect specific, 3D. Geoex MCG’s regional 2D seismic survey offshore Morocco provides an opportunity to conduct such an analysis (Figure 1). Despite numerous wells in the proximal domain of the margin, the distal portion of the Morocco offshore, more specifically on oceanic crust, remains significantly underexplored. This regional long offset 2D provides significant insights into key locations for further exploration invoking an untested petroleum system that has been demonstrably active.
