Abstract Sedimentary facies in the distal parts of deep‐marine lobes can diverge significantly from those predicted by classical turbidite models, and sedimentological processes these environments are poorly understood. This gap may be bridged using outcrop studies theoretical models. In Skoorsteenberg Formation (South Africa), a downstream transition thickly bedded sandstones to argillaceous, internally layered hybrid beds, is observed. The beds have characteristic stratigraphic spatial...

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 The Middle Devonian Gauja Formation in the Baltic Basin preserves tide‐influenced delta plain and front deposits associated with a large southward prograding complex. outcrops extend over 250 km from southern Estonia to Lithuania. succession can be divided into 10 facies associations recording distributary channel belts that became progressively more tide influenced when traced southwards towards palaeo‐shoreline, separated by muddy intra‐channel areas where deposition was...

The topography of the seabed (orientation and gradient) rheology flows greatly influences character basin-floor turbidity current deposits. Therefore, submarine fan pinchouts can help to constrain basin configurations at time deposition. Although depositional architecture lobe has been documented in various basin-fills, quantification rates change different palaeogeographic positions not attempted previously. Here, we utilize extensive outcrops research boreholes from oblique up-dip pinchout...

Abstract Deep‐water stratigraphic successions from syn‐ to post‐rift stages are an archive of evolving physiographic configurations, and can record axial transverse sedimentary sources. The healing topography decreases the influence syn‐rift structures on sedimentation patterns transport processes over time, which leads a long‐term transition dominantly dispersal patterns. Halten Dønna terraces, offshore mid‐Norway, comprise series rift‐related sub‐basins established during Jurassic, were...

Abstract The sedimentological, architectural, and stratigraphic database from one investigated shelf-margin clinothem complex in the Eocene Central Basin of Spitsbergen suggests that dominating process regimes facies products may change several times during a sea-level cycle, even though basin-wide processes are constant. Continuous mountainside exposures were by combination “walking-out” surfaces geometrical elements, closely spaced detailed vertical sections, tracing on helicopter photo...

Improved prediction of the recovery oil-in-place in basin-floor fan reservoirs requires accurate characterization and modelling multiscale heterogeneities. The use outcrop analogues is a key tool to augment this process by documenting quantifying sedimentary architecture, hierarchy facies relationships. A 3D geological workflow presented that tests impact fine-scale heterogeneities within lobe complexes on reservoir connectivity. Construction models complex allows realistic depositional...

Submarine lobes form at the distal end of sediment gravity flow systems and are globally important sinks for sediment, anthropogenic pollutants organic carbon, as well forming hydrocarbon CO 2 reservoirs. Deep-marine, near bed or bottom currents can modify pathways distribution by directly interacting with modifying seafloor morphology. Deciphering nature gravity- interaction, particularly in ancient systems, remains a challenge due to lack integrated datasets necessary oceanographic...

Abstract Submarine slope channel systems have complicated three‐dimensional geometries and facies distributions, which are challenging to resolve using subsurface data. Outcrop analogues can provide sub‐seismic‐scale detail, although most exhumed only afford two‐dimensional constraints on the depositional architecture. A rare example of an accessible fine‐grained complex set situated in a tectonically quiescent basin that offers seismic‐scale, down‐dip across‐strike exposures is Klein...

Sedimentary facies in the distal parts of deep-marine lobes can diverge significantly from those predicted by classical turbidite models, and sedimentological processes these environments are poorly understood. This gap may be bridged using outcrop studies theoretical models. In Skoorsteenberg Fm., a downstream transition thickly-bedded sandstones to argillaceous, internally layered hybrid beds is observed.

Recent studies characterizing outcrop analogues of deep-water lobe reservoirs have demonstrated that these deposits are stacked in a hierarchical manner with characteristic element scales vary between turbidite systems. Static connectivity and dynamic numerical modelling idealized, non-hierarchical systems identified the presence discrete net-gross or amalgamation ratio thresholds control flow. The objectives current work to compile geostatistical description hierarchy; develop scheme able...

Abstract Clean basal and capping argillaceous sandstone couplets in deep water settings have been previously interpreted as the result of spatially segregated turbidity currents debris flows or spatio‐temporal transitioning a turbulent flow to transitional/laminar state. However, this paper presents three‐dimensional laboratory experiments demonstrating that single sediment‐gravity can develop sand–mud by autogenic remobilization sediments are still process being deposited. This appears...

Deep-water lobe deposits are arranged hierarchically and can be characterized by high net:gross ratios but poor sand connectivity due to thin, laterally extensive, shale layers. This heterogeneity makes them difficult represent in standard full-field object-based models, since the sands an model not stacked compensationally become connected at a low ratio. The compression algorithm allows generation of low-connectivity models ratios, including amalgamation as independent input parameters....

Scours, and scour fields, are common features on the modern seafloor of deep-marine systems, particularly downstream submarine channels, in channel-lobe-transition-zones. High-resolution images have improved documentation large scale, coalescence, distribution these scours systems. However, their scale high aspect ratio mean they can be challenging to identify outcrop. Here, we document a large-scale, composite erosion surface from exhumed stratigraphy Unit 5 Permian Karoo Basin succession...

Summary Assessing a hydrocarbon reservoir for development involves using various types of data including seismic acquisitions, analogue production data, and exploration/offset well data. In contrast, assessing saline aquifers CO2 injection is typically constrained by limited project finances lack previous exploration experience. As result, there high level uncertainty regarding depositional environment the resulting effect this on injectivity. The knowledge about aquifer's architecture poses...

Dissolution of CO2 is a critical chemical trapping mechanism for the secure storage in subsurface. However, there considerable uncertainty over rate and cumulative mass via dissolution, particularly longer timescales. Naturally occurring reservoirs are valuable analogues that can help to predict long-term performance anthropogenic storage. The 3He δ13C content within natural be used quantify fraction gaseous removed by dissolution. Previous studies show dissolution dominant form trapping. In...

Reservoir modelling and production forecasting are challenging as we trying to describe the whole reservoir predict dynamic behaviour of all wells based on a limited amount measurements. Taking advantage data available at various scales, understanding uncertainties in model flow simulations, become then important allow for robust development operation field. In uncertainty analysis, an accurate representation is preferred, several realisations that probable within span should be considered....
