Sampling And Characterization Of Difficult Fluids Course

F Brent Thomas

This intermediate course explores the challenges of sampling and characterizing volatile hydrocarbon fluids in low permeability porous media. It covers fundamental phase behavior concepts to identify and resolve difficulties encountered in both oil and gas condensate reservoirs. The course emphasizes the importance of understanding fluid behavior in situ, including issues like solids precipitation and phase separation during sampling. It also addresses both bottomhole and surface sampling techniques, highlighting the advantages and limitations of each. With a focus on unconventional reservoirs, the course aims to improve fluid characterization accuracy, impacting reservoir evaluation and asset management decisions.Read more...
