Phase Behaviour Modelling and PVT Creation using WinProp

Learn how to predict phase behaviour and characterize the reservoir fluids for reservoir simulation using WinProp. Review basic concepts of the petroleum fluid phase behaviour and gain hands-on experience using WinProp to Characterize the heavy fraction of the petroleum fluids, lump and split components, match laboratory PVT data through regression, simulate first and multiple contact miscibilities, perform multiphase equilibrium calculations, and perform phase diagram generation. Users will also learn to characterize the fluid and tune the EoS in order to obtain a fluid model suitable for inclusion in GEM, STARS, or IMEX datasets, and analyze WinProp results.

Description of mechanisms involved:

• Fundamentals of phase behaviour and PVT modelling
• Introduction to WinProp for phase behaviour calculations
• Techniques in splitting, lumping and grouping of heavier hydrocarbons
• Multi-phase flash calculations and creation of phase envelopes
• Detailed interpretation and analysis of lab PVT data
• Determine Minimum Miscibility Pressure (MMP) and Multi-Contact Miscibility (MCM)

Exercises with STARS Matching various laboratory experiments and EoS tuning by regression, including:

• Saturation Pressure, Gas-Oil Ratio (GOR), and etc.
• Constant Composition Expansion (CCE) and Constant Volume Depletion (CVD)
• Separator Test, Swelling Test, and etc.
• Density and viscosity of oil as a function of Pressure and/or Temperature
• Output of different Fluid Model types for Black Oil (IMEX), K-Value (STARS), and Compositional (GEM)
