Characterisation and Modelling of Carbonate Naturally Fractured Reservoirs

Sunday, 19 January 2014, 0900–1600, Meeting Room 216, QNCC, Doha, Qatar

Instructor: Shawket G. Ghedan, Computer Modeling Group, Ltd, Calgary, Canada

Course Outline:

The course starts by covering the geological aspects of carbonate fractured reservoirs, NFRs, in terms of matrix and fractures characterization and determination of its intrinsic and effective properties needed for reservoir modeling. It then continues to explore the recovery mechanism of naturally fractured reservoirs and its difference than those of conventional oil reservoirs. Further, the course presents the concepts of Wettability, Pc and Kr curves and their importance in the recovery mechanisms of naturally fractured reservoirs. Modeling approaches will differ based on the types of the Carbonate NFR, and the oil recovery processes encountered during primary, secondary and tertiary recovery techniques. The course explains the modeling approaches of Standard Dual Porosity, Dual Porosity with Multiple Interacting Continua, Dual Porosity with Vertical Refinement, Dual Permeability, and finally Dual Permeability with Vertical Refinement. Further, the course explores the various matrix-fracture transfer function and the related shape factors. Finally the course would shed light on the topic of thermal recovery from Carbonate Naturally Fractured Reservoirs which is taking a lot of attention lately.
