Fluid Properties and Phase Equilibria (PVT)

---

Disciplines: Reservoir

Course Description

This (PVT) class will focus on the advanced and key topics of reservoir fluid properties, fundamentals, practical measurements and workflows. In the class, we will emphasize use cases and various examples including modern PVT report reviews as well as the key use-case related elements of equation of states (EOS s) that are often shared in our industry, especially in relation to reservoir models and other tools that use the PVT data. In addition, we will give a broad view of the new developments in all elements of the development cycle, including exploration, reservoir and production management, EOR/IOR and even CO2 sequestration. As the complexity of fluids and the reservoir conditions become more challenging, progress in the computational area is also being made, such as, new EOS models and computational techniques, advanced characterization methods, etc. Therefore, complex fluids and their implications will be inherently part of this class. One of the new topics that we will also introduce is the use of data-centric/machine learning methods in the area of hydrocarbon fluid properties

1. Introduction
   • Why do we need fluid data: well testing, in place volumes, material balance equation, etc
   • Classification of Reservoir fluids: Black oils to volatile fluids to dry gases and Volumetric/PVT experiments
2. Computational Aspects
   • Black oil & gas correlations, Definitions: API, SG (gas & oil), Bo, Rs, Pbp, Gas Gravity, Z-factor etc.
   • Machine learning and data-centric models
   • Fluid Properties Fundamentals ("Thermodynamic Aspects"- EOS formulas, underlying assumptions, reasoning etc), and HC characterization: SCN groups & implications
   • EOS Applications and their use
3. Introductory Examples/Exercises: Compositional Data and Fluid Characterization
   • Review of modern PVT reports & QC: Essential data/experiments
   • Data Use: Measured data/Key data
   • CN distribution and its implications
4. QC and Tuning (Recipe/Methodology): Justification and how to start tuning process
   • Exercises (oils and condensates): Various classes of fluids/report formats – (instructor driven), Tuning/Regression, Interfacing with other packages
5. Compositional Grading
6. OBM Contamination
   • OBM Contamination and decontamination
7. Viscosity models 
8. Emulsions
9. CGR Correlations and Applications
10. New Developments: Miniaturization, Pore Proximity, Life Cycle Management, MD, Data Driven/Hybrid Models (time permitting)
11. MMP/MME: interaction of phase behavior and flow (time permitting)
