Thermal Recovery Methods for Heavy Oil Fields Training Course
This course is designed to cover all the traditional and modern Thermal Recovery Methods used in the oil industry for Heavy Oil recovery. Perhaps no other single subject dominates the oil industry like thermal recovery. For many of oil fields, particularly where low-to-medium gravity oils are found or where the oil viscosity is unfavourable for conventional EOR methods application, Thermal Recovery Methods are the best techniques for ultimate recovery. Vast deposits of heavy oil exist in Canada, Venezuela and USA that are amenable to recovery by Thermal Recovery. Thermal Recovery is usually applied to heavy to medium oils, however these methods can be applied to any field being considered and be competitive with alternative methods. The course consider the following methods: Cycle Steam Injection, Double Injection Nitrogen-Steam, CO2-Steam Injection, Flue Gas-Steam Injection-This methods have given excellent results in China and Louisiana (USA), Steam Drive Process, Hot Water Injection Processes, In Situ Combustion Processes, Cold Heavy Oil Production with Sand (CHOPS), Vapor Extraction Method (VAPEX) and Steam-Assisted Drainage (SAGD).
Who Should Attend
This course is designed for Production and Reservoir Engineers and their supervisors; Chemical Engineers Associated with crude oil production in areas of high viscosity. Technical field personnel and services companies representatives to obtain or increase the understanding of the overall concepts and principles of improving the efficiency of production, treatment and the handling of heavy crude oils.
