This course is devoted to acquire the basic background in Siliciclastic facies sedimentology in order to apply them to subsurface data at the appropriate scale as commonly done in the oil & gas industry for both regional exploration studies & detailed reservoir characterization for field development.It starts with a review of erosional and hydrodynamical processes (wind- currents- tide- and waves as well as gravity) controlling sedimentary structures & facies deposition (including movies) followed by a review of facies, facies sequences and sedimentary environments from the continental domain (Fluvial- Lacustrine & Aeolian) grading to deltas, non-deltaic coastlines and shelf and ending into deep water settings with turbidites and slumps.Facies will be analyzed by the way of outcrops, cores and subsurface data ( logs).
Facies sequences will be also address in order later on to define depositional environments by multi 2D correlations or using 3D Seismic amplitude maps. A special attention will be paid to sand body geometry in order to better constrains the model and select the appropriate analogs.
The different chapters of this formation will be punctuated by practical applications deriving from outcrops and subsurface examples.
