High Viscosity Crude Oils Optimization Production Technology

COURSE DESCRIPTION

Experience in the production of heavy crude oils has demonstrated that the majority of conventional production systems and treatments are highly inefficient. The production, treatment, storage and fluid transference through pipelines of high viscosity crude oils are associated to severe and costly technical problems. The main objective of this course is to increase the efficiency in the production of heavy crude oil areas and reduce significantly the high cost of producing high viscosity crude oil. Other objectives are; the study of conventional methods and operational problems associated with the use of those methods in the production of heavy oil areas. A study of all methods available to handle high viscosity production areas in the world.  Simplified mathematical aspects of the simulation of diluent fluid consumption.  Study of theoretical field constituted by six wells producing different types of heavy crude oils at different rates of production.  A study in depth of an actual field case. This course includes a discussion on “Paraffin and Asphaltene deposition in the production of heavy crude oils”.
