EoS Characterization
Tune EoS to accurately match laboratory results and predict fluid behavior.
- Analyze two EoS models - surface (separator) conditions and reservoir conditions
- Choose from multiple EoS models, E.g. Peng-Robinson and Soave-Redlich-Kwong EoS models (2 and 3 parameter versions), to match lab data
- Create separate EoS models for surface (separator) conditions and reservoir conditions
- Regression on composition and properties to allow for easy matching of lab data
- Automatic parameter selection and built-in parameter bounds simplifies regression process
- Linear temperature-dependent volume shift model to accurately match lab calculated density
- Match separator data separately from PVT data gathered at reservoir temperature using differential liberation experiments
- Group parameters for regression and apply varying weights to specify importance of matching distinct parameters
Reservoir Fluid Characterization
Understand property distribution within a reservoir fluid system, under different depletion scenarios.
- Exponential, two-stage exponential, and gamma distribution functions for characterization calculations
- Fraction splitting and component lumping to simplify creation of pseudo-components
- Specify own lumping criteria or use WinProp internal algorithm to determine lumping criteria
Miscibility Prediction
WinProp’s multiple contact miscibility option performs calculations under condensing, vaporizing, or condensing-vaporizing drives.
- User-friendly component lumping and fraction splitting options
- Extensive library of hydrocarbon and non-hydrocarbon components
- First contact miscibility pressure calculation to match data and understand the fluid mixture properties
- Differential evolution algorithms provides more stable search for minimum miscibility pressure (MMP) calculations
- Multiple mixing cell method of Ahmadi and Johns to calculate minimum miscibility pressure
- Create ternary diagrams to graphically interpret miscibility mechanisms and calculate how to achieve multi-contact miscibility
- Phase split calculation of Li, Johns and Ahmadi for multi-contact miscibility calculations
Asphaltene and Wax Precipitation Modelling
Save time by quickly characterizing Asphaltene and Wax deposition fluid model for use in compositional simulation.
- Multi-component solid solubility model is coupled with Equations-of-State (EoS) for descriptions of asphaltene or wax precipitation
- Model up to three fluid phases in equilibrium with the precipitate as a multi-component solid
Aqueous Phase Properties
Model the solubility of CO2, H2S, and light hydrocarbons in water of varying salinity.
- Accurately predict water content of gases
- Extensive library of geochemical reactions for rock mineralogy interaction with the aqueous phase
- Standard phase property table also includes entropy, enthalpy and heat capacity
