Appraisal and development of clastic reservoirs rely on sandbody geometries and porosity. In addition, most clastic reservoirs are afected by natural fractures which have either a positive or negative impact on reservoir quality and well performance, be it positive from the presence of open fracture networks or negative from the presence of low k fractures and faults. This course sets out to equip the oil industry geoscientist and reservoir engineer with the essential basic knowledge to work with clastic reservoirs. The course material is partially based on an update of the paper Depositional Sequence Response to Foreland Deformation in the Upper Cretaceous of the Southern Pyrenees, Spain, AAPG Bulletin, 2000, by Ardèvol et al., and forthcoming papers in preparation.

Deltaic Sandstones

Dynamic stratigraphy, architecture, geometry and facies analysis

Delta plain

  • Fluvial channels: tide-storm influence, depositional bars


Delta front

  • Lacustrine lobes
  • Fluvial: mouth bars, lobes
  • Tidal: tidal flats, shoals, tidal bars
  • Wavy / estuarine: strand plain, barrier, foreshore, shoreface



  • Offshore sands


Fracture analysis (optional)
