Depositional Environments A sedimentary environment is a geographic location characterized by a particular combination of geologic processes and environmental conditions. Geologic processes include the currents that transport and deposit sediments (water, wind, or ice) and the plate tectonic settings that affect sedimentation.Jun 1, 2017 · The present study points to a transgressive shoreface depositional environment for the intra-Draupne Formation sandstone, with localized fan-delta sediment input. This has important reservoir implications, in particular away from current well control. The depositional environments associated with sandstones are very important and they range from terrestrial to deep marine, including: Fluvial ( alluvial fans, river sediments); Deltaic (levees, distributary deposits ,mouth bars and other sediments formed where river meets a lake or sea); Aeolian (wind-blown dune sands formed in coastal and dese...

Depositional features include distributary channels, river-mouth bars, interdistributary bays, tidal flats, tidal ridges, beaches, eolian dunes, swamps, marshes, and evaporite flats (Coleman, 1976).Understanding the depositional setting of siliciclastics reservoir is fundamental process to exploration and development of hydrocarbon reservoirs and to the multi-phase cycle of the oil and gas industry. Typically, core samples from existing or potential reservoirs can be used for interpretation of depositional environment. However, the lack of core samples in certain reservoirs represents a ...Jul 10, 2011 · The table below includes specific environments where various types of sediments are deposited and common rocks, structures, and fossils that aid in deducing the depositional environment from examining a sedimentary rock outcrop. Although this is not a complete list, it is a good introduction to depositional environments. Continental. Transitional. The heterolithic lower part of the fan is commonly weathered and covered by scree. Logs were correlated by assigning depositional sub-environments based on their lithofacies association and bounding surfaces (Prélat et al., 2009).
