Abstract Hybrid event beds comprising clay‐poor and clay‐rich sandstone are abundant in Maastrichtian‐aged sandstones of the Springar Formation north‐west Vøring Basin, Norwegian Sea. This study focuses on an interval, informally referred to as Lower Sandstone, which has been penetrated five wells that distributed along a 140 km downstream transect. Systematic variations bed style within this stratigraphic interval used infer variation flow behaviour relatively proximal distal settings,...
Reservoir properties of deep-marine sandstones deposited by various sediment-gravity-flow types in the northwestern Voring Basin (Norwegian Sea) are characterized using detailed sedimentological and petrographic analyses. The quartz arenites subarkoses, having similar mineralogical compositions, a low degree diagenetic modification, to moderate volumes cement (up 6%). However, significant textural variability is observed for sandstone types, which were subdivided based upon their interpreted...
In August 2022, the world's longest running offshore industrial CO 2 injection project celebrated its 26-year anniversary. During these years, Sleipner has been invaluable in demonstrating that storage is feasible, safe, and efficient. We will here show how time-lapse seismic monitoring of plume development revealed depositional architecture Utsira Formation, thin mudstone layers have contributed to distributing a larger rock volume, promoting trapping by dissolution. The relatively shallow...
The requirement to reduce global CO2 emissions has resulted in the need for rapid, safe development of Carbon Capture and Storage (CCS) projects. Regional storage clusters, that often lie adjacent past or present hydrocarbon hubs associated infrastructure, are seen as a potential fast-track routes toward decarbonisation. These complex subsurface settings pose critical challenge predicting pressure interference not only between planned sites but also with existing oil gas fields. Injection...
ABSTRACT For nearly three decades, Equinor's Sleipner Carbon Capture and Storage project has demonstrated how the application of geological principles, modelling techniques analysis repeated time‐lapse (4D) seismic data helped to characterise CO 2 plume migration within late Miocene–early Pliocene Utsira Formation. However, influence stratigraphic complexity on fluid been rather poorly understood. This resulted in a significant degree uncertainty characterisation storage formation, including...
Abstract Ichnological studies are still in their infancy when it comes to the interpretation of deep‐marine deposits. The Eocene–Oligocene turbidite system Grès d'Annot Formation south‐east F rance is well‐studied sedimentologically, but its trace‐fossil content poorly known. Here, an integrated ichnological–sedimentological study presented from Annot sub‐basin for first time, which demonstrates value interpreting proximal distal and axial marginal trends confined systems. A comprehensive...
ABSTRACT Well-developed detrital clay grain coats are observed in deep-marine sandstones of the Upper Cretaceous Springar Formation Vøring Basin Norwegian Sea. The form thin and compact rims on individual sand grains meniscus-shaped bridges between grains. These well-developed found high-density turbidites proximal hybrid event beds with common to pervasive dewatering structures deposited proximity base a syndepositionally active basin high. Here, one exploration well, throughout sandstone...

Summary This contribution presents an integrated case study of Well X, which targeted a drift-influenced slope channel complex in Cretaceous and Neogene stratigraphy Block 2, offshore Tanzania. The large-scale architecture several complexes reveals interaction with associated drift deposits "levees", displaying high degree asymmetry, being developed on the northern side margins. We present hypothetical model for these large, fine grained interpret them as result flow stripping silt clay form...
