About the course
This course deals with the engineering of gas condensate and volatile oil reserves. The course proceeds from simple techniques to determine the values of fluid properties and estimate reserves to the techniques of preparing equations of state for compositional simulation studies.Both types of procedures require the use of laboratory data, so the laboratory procedures and results are carefully discussed. Equations of state are discussed in detail, starting with basic definition, mixing rules, definition of the mixing rule parameters, then going on to extending the single-carbon number composition, grouping into pseudocomponents, characterizing the pseudocomponents, and finally adjusting the equation of state to cause a match of calculated results with laboratory data. Exercises are worked by the participants at each step of the characterization process.
