OUTLINE
The course addresses the production performance of wells and gathering systems. It teaches the fundamentals and the relevant engineering methods and computation tools. The theory is applied for planning, designing, operating, monitoring, and analyzing of field production performance.

The course addresses the behavior of individual oil and gas wells, as well as the integrated production system. It examines the steady-state production and the transient characteristics. It covers the inflow from the reservoir to the well-bore dealing with relevant aspects of reservoir behavior and depletion changes. It analyzes the production flow network and studies its hydraulic and thermal characteristics. It discuses the production constraints in the payzone, the wellbore and the flowlines. It discusses the effect of artificial lift and pressure boosting facilities on production performance and presents the impact of emerging technologies, such as downhole or seabed oil-water separation, on flow performance.

TARGET ATTENDEES
The course is aimed at engineers of all disciplines, with or without practical production technology experience. Petroleum technology background (reservoir, production, well engineering) is of advantage but not necessary. Development geologist, petro-physicists, drilling engineers, facilities engineers and other professionals involved in preparing field development schemes, planning production facilities, and conducting production operations will be benefited.
