COURSE OVERVIEW
From reserve estimation and hydrocarbon reservoir modeling to Enhanced Oil Recovery (EOR), a solid understanding of PVT (Pressure–Volume–Temperature) phase behavior and reservoir fluid properties is essential for efficient and profitable hydrocarbon production and processing in the oil and gas industry.
This course provides comprehensive coverage of reservoir fluid composition, phase behavior, and fluid classification. It addresses best practices for obtaining high-quality PVT samples, the effects of contamination, and the interpretation of laboratory PVT tests using correlations and modeling techniques. Key fluid properties—such as density, viscosity, and interfacial tension—are examined in detail, along with the evaluation and practical application of PVT reports.
Participants will also explore fluid analysis and characterization methods, including Equation of State (EoS) tuning using a commercial modeling tool and its application in reservoir simulation studies. A complimentary 30-day license of Hydrafact software will be provided to support selected calculations and practical exercises.
The course includes discussion of common sources of error in PVT analysis and interpretation, supported by real case studies to reinforce learning and practical application.
