CDGA

This course is designed to develop skills in understanding of the basic geometry and Petrophysical characteristics of carbonate reservoirs which can exhibit highly heterogeneous and complex properties. A key dynamic of the course is a series of exercises utilizing subsurface data sets that include core data, geophysical logs and seismic are given. A focused and a comprehensive approach is needed to better understand the nature of the rock containing the fluids and the flow properties within the porous and often fractured formations. This involves detailed understanding of the fluids saturation, pore-size distribution, permeability, rock texture, reservoir rock type, and natural fracture systems at different scales. Depositional fabric, grain type and size and subsequent diagenetic modifications are the major controls on carbonate reservoir behavior. The complex inter-relationship of the depositional and burial history can be unraveled to allow prediction of reservoir facies and reconstruction reservoir models.
