Course Description
This course offers both the fundamentals of oil and gas reservoir engineering and the practical applications to conventional and unconventional (fractured, tight gas) reservoir problems. Estimation of oil and gas reserves, volumetric and material balance methods, reservoir, well recovery and performance analysis are presented. Well testing methods, behavior of reservoir under primary, secondary and tertiary recovery methods, and different drive mechanisms, are discussed. Field development strategies and planning, including horizontal well and multi-stage fracturing are presented. Displacement of oil by gas and water, principles of reservoir simulation and new technical developments are introduced. The course is intended for petroleum engineers, geologists, geophysicist and others who are interested in understanding the fundamental principles of reservoir engineering and the basic behavior and performance of hydrocarbon reservoirs. The objective of the course is to provide a more comprehensive understanding of the characteristics of oil and gas reservoirs, from fluid and rock characteristics through reservoir definition, delineation, classification, development plan, and production. Data collection, integration and application towards maximizing recovery are emphasized.
