DESCRIPTION AND OBJECTIVES

This course aims to develop a fundamental knowledge of the basic geological and petrophysical concepts and apply this knowledge to understand reservoir geology. The course covers mechanical and chemical compaction, cap rocks (shales and salt)- overpressure, fluid flow in porous media, petrophysics (well logs and cores), stress condition in reservoirs, reservoir models, production geology, sandstone reservoirs, carbonate reservoirs, and several case studies. As well as reservoir rock types, carbonates and non-marine reservoirs. Reservoir properties, depositional and diagenetic controls; fluid properties and their saturation; hydrocarbon distributing and fluid contacts; reservoir zonation and thickness mapping reservoir pore spaces configuration; mapping reservoir heterogeneity; reservoir estimation and calculation of reservoir volume.

INTENDED LEARNING OUTCOMES

This course will enable to discuss main concepts of Reservoir Geology, especially petrophysical concepts, used in the description of reservoirs and the way the corresponding rock properties are measured from cores. Access to rock properties from log interpretation and compare to core measurements. Define petro-facies, electro-facies and rock-types, Integrate cores, logs and well tests data for reservoir modeling. Apply the workflow for building a reservoir static model using dedicated software. Identify and assess the uncertainties within the geomodeling workflow.
