A screening assessment of the impact of sedimentological heterogeneity on CO2 migration and stratigraphic-baffling potential: Johansen and Cook formations, Northern Lights project, offshore Norway

We use a method combining experimental design, sketch-based reservoir modelling, and single-phase flow diagnostics to rapidly screen the impact of sedimentological heterogeneities that constitute baffles and barriers to CO2 migration in the Johansen and Cook formations at the Northern Lights CO2 storage site. The types and spatial organisation...

Early post-rift depositional systems of the Central Atlantic: Lower and Middle Jurassic of the Essaouira-Agadir Basin, Morocco

Passive margins are traditionally regarded as tectonically quiescent, however the increasing recognition of significant post-rift tectonic uplift along their flanks offers an important control on sediment delivery. The most extensive record of the early post-rift succession of the Central Atlantic Margin (CAM) is found in the Lower and Middle...

The Guadiaro-Baños contourite drifts (SW Mediterranean). A geotechnical approach to stability analysis

Two Quaternary plastered contourite drifts, with terraced and low-mounded morphologies, make up the continental slope and base-of-slope in the northwestern Alboran Sea, respectively, between the Guadiaro and Baños turbidite systems, close to the Strait of Gibraltar. Considering their significant lateral extent, the link between the contourite...

Untangling Sea Level and Sediment Supply History of the Panther Tongue Delta, Utah, USA

The Panther Tongue is a fluvio-deltaic parasequence in the lower part of the Star Point Sandstone formation in the Wasatch Plateau, central Utah, deposited during the late Cretaceous period. The sedimentology of the Panther Tongue and adjacent beach ridges parasequence has been extensively described by Hwang & Heller (2002) and Hampson et al. ...

Static Reservoir Model of Crevasse Splays in the Colorado River System, Salar of Uyuni, Bolivia

The Altiplano Basin (Bolivia) exhibits one of the best examples of dryland river systems with a low gradient, where it is possible to obtain field data to build 3D high-resolution geological models of different sediment bodies. This study presents the development and understanding of a 3D geological model for crevasse splays deposited in this...

Control of Fluvial Architecture on the Spatial Distribution of Arsenic Rich Ground Water

In Bihar, India, arsenic rich aquifers are used as a drinking water source by millions of people, even though the arsenic concentration in some places is so high it causes serious health issues. The arsenic concentrations in the aquifers show a large spatial variability, one that is presently unpredictable. The most important factors which play...

Sand-mud erosion from a soil mechanical perspective

‘Wetlands’ in tidal lagoons and estuaries are among the most valuable ecosystems in the world. Managing these systems requires both a thorough knowledge and validated tools to predict their behavior and development. An important morpho-dynamic process herein is the erosion (‘pick-up’) of the bed, which are in inter-tidal areas often composed of...

Geologic origin of arsenic groundwater contamination in Maner block, Bihar, India

Arsenic contamination of the groundwater and as a consequence, of the drinking water, has developed to a major problem for many regions globally during the last decades (Chile, China, United States, Argentina, and Mexico). The issue of Arsenic contamination has already been studied extensively in West Bengal, India and Bangladesh, which are some...

Sedimentology and 3D architecture of a bioclastic calcarenite complex on Favignana, southern Italy: Implications for reservoir modelling

The island of Favignana provides an exceptional three-dimensional insight in the architecture of a Lower Pleistocene bioclastic calcarenite complex. Due to the degree of quarrying, a large amount of outcrops is available in the eastern part of the island. Two campaigns resulted in the logging of stratigraphic sections, recording of sedimentary...

The Cambro-Ordovician Sequence in the Petra Area, Jordan: Sedimentology and Stratigraphy

The Ram Group in Jordan forms part of a massive and voluminous quartz-rich blanket that covered North Africa and Arabia, the former northern margin of Gondwana during the Early Paleozoic. The lack of vegetation on the vast peneplained and tectonically stable margin resulted in the development of extensive alluvial systems markedly different in...

Imaging frozen glacio-fluvial bedrock valley infill using Ground Penetrating Radar

A Ground Penetrating Radar (GPR) survey was conducted in April of 2008, collecting 27 km of radar profiles in Sandflugtdalen, a permafrosted glacio-fluvial bedrock valley in West Greenland. Due to low electric permittivity of frozen soil, GPR has good depth penetration of permafrost, up to 80 m using low-frequency (50 MHz) antennae. Resolution...
