“…These composite analogues are adoptable as quantitative facies models (cf. Baas et al 2005;Colombera et al 2013) that have been proven to be useful for the definition of conceptual models of reservoir heterogeneity, for conditioning stochastic geocellular reservoir models (cf. Colombera et al 2012b), and for guiding well-to-well correlations of sandbodies or mudstone units (Colombera et al 2014;2016).…”

The Shallow-Marine Architecture Knowledge Store (SMAKS) is a relational database devised for the storage of hard and soft data on the sedimentary architecture of ancient shallow-marine and paralic siliciclastic successions, and on the geomorphological organization of corresponding modern environments. The database allows incorporation of data from the published literature, which are uploaded to a common standard to ensure consistency in data definition. The database incorporates data on geological entities of varied nature and scale (i.e., surfaces, depositional tracts, architectural elements, sequence stratigraphic units, facies units, geomorphic elements), including attributes that characterize their type, geometry, spatial relations, hierarchical relations, and temporal significance. Furthermore, geological entities are assigned to depositional systems, or to parts thereof, that can be classified on multiple parameters (e.g., shelf width, delta catchment area) tied to metadata (e.g., data types, data sources).The SMAKS permits the quantitative characterization of modern and ancient shallow-marine and paralic clastic depositional systems. It aims to serves as a repository of analogue information for hydrocarbon-bearing successions, and as a research tool, applicable to aid the development of facies models or to assess the sensitivity of depositional systems to particular controlling factors, for example.To demonstrate the wide applicability of the database in fields of both fundamental and applied research, example database output is presented that (i) includes data from wave-, tide-, and fluvial-dominated shallow seas and sedimentary successions, and (ii) covers a wide depositional spectrum, from backshore to shelf-edge settings. The examples include information on the facies organization of different types of paralic sub-environments, on the hierarchical arrangement of architectural elements that form deltaic constructional units in Quaternary deltas, on the morphometry of modern and Quaternary tidal sand ridges, and on the geometry of parasequence-scale nearshore sandstone belts from the Upper Cretaceous of the Western Interior Seaway in Utah (USA).

“…In this study, model inputs to constrain channel-form and bar geometries have been acquired from field-based measurements of outcrops and modern systems, from remotely sensed satellite imagery, and from subsurface data (e.g., seismic, cores and well logs). Data that describe such real-world examples are held in the Fluvial Architecture Knowledge Transfer System (FAKTS) -a relational database that stores quantified sedimentological data from many modern classified fluvial systems and analogue ancient fluvial successions (see details in Colombera et al, 2012Colombera et al, , 2013Colombera et al, , 2017, which is populated with sedimentological data from the published literature and our own field studies.…”

“…mudstone) typical of deposition in fluvial overbank settings in response to nonconfined flood events (Medici et al 2015). Such overbank deposits tend to be preferentially preserved in basins subject to rapid rates of subsidence whereby channel emplacement by avulsion does not fully rework them (Colombera et al 2013).…”

Characterization of a fluvial aquifer at a range of depths and scales: the Triassic St Bees Sandstone Formation, Cumbria, UK

2017

Fluvial sedimentary successions represent porous media that host groundwater and geothermal resources. Additionally, they overlie crystalline rocks hosting nuclear waste repositories in rift settings. The permeability characteristics of an arenaceous fluvial succession, the Triassic St Bees Sandstone Formation in England (UK), are described, from core-plug to well-test scale up to~1 km depth. Within such lithified successions, dissolution associated with the circulation of meteoric water results in increased permeability (K~10 −1 -10 0 m/day) to depths of at least 150 m below ground level (BGL) in aquifer systems that are subject to rapid groundwater circulation. Thus, contaminant transport is likely to occur at relatively high rates. In a deeper investigation (> 150 m depth), where the aquifer has not been subjected to rapid groundwater circulation, well-test-scale hydraulic conductivity is lower, decreasing from K~10 −2 m/day at 150-400 m BGL to 10 −3 m/day down-dip at~1 km BGL, where the pore fluid is hypersaline. Here, pore-scale permeability becomes progressively dominant with increasing lithostatic load. Notably, this work investigates a sandstone aquifer of fluvial origin at investigation depths consistent with highly enthalpy geothermal reservoirs (~0.7-1.1 km). At such depths, intergranular flow dominates in unfaulted areas with only minor contribution by bedding plane fractures. However, extensional faults represent preferential flow pathways, due to presence of high connective open fractures. Therefore, such faults may (1) drive nuclear waste contaminants towards the highly permeable shallow (< 150 m BGL) zone of the aquifer, and (2) influence fluid recovery in geothermal fields.
