2 Appraisal and development of clastic reservoirs rely on sandbody geometries and porosity. In addition, most clastic reservoirs are affected 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 L. Ardèvol, J. Klimowitz, J. Malagón, P. C. Nagtegaal, and forthcoming papers in preparation. Instructors: Lluís Ardèvol i Oró and Jon Gutmanis Assistants: Davinia Díez-Canseco or Marc Tudela Location: south-central Pyrenees, the course begins and ends in Barcelona Cost: EUR 2,850 Dates: May 7-10; September 17-20, 2018 Closing date: 10 days prior the course begins Class size: 12 / 4 participants Level: basic / skill Delivery: field trip + 1h daily classroom Physical demand: easy short hike on level terrain

5 Standard daily program Objective: to take the group through the shallow-marine clastic reservoir characterisation workflow. We will integrate discussions at specific outcrops with classroom sessions to present the essentials of modern dynamic stratigraphy and sedimentology, and fracture characterisation.
