Fluid Characterisation
PVTP provides a consistent PVT framework, ensuring accurate fluid behaviour across the system and enabling seamless conversion between compositional and black oil models for vendor-neutral integrated modelling.
Matching on Lab Experiments
PVTP enables EOS development by matching lab data such as CCE, CVD, differential liberation, and separator tests. It includes quality checks for pseudo components, flexible workflows, and multiple regression techniques to ensure consistent, monotonic property behaviour. It also features proprietary property databases, pseudo-component handling, volume shift initialisation, advanced phase detection, and EOS/black oil viscosity options, including CO₂-specific corrections.
Lumping / Delumping
PVTP supports integrated modelling through proprietary lumping and delumping algorithms that preserve transformation rules within compositions. Unlike marker-based methods, this allows consistent conversion between reservoir and process models across multiple vendors, enabling seamless compositional handling throughout the workflow.
Carbon Dioxide
PVTP extends standard EOS models with proprietary corrections to accurately represent CO₂ behaviour across wide pressure and temperature ranges. This enables reliable modelling of CO₂ mixtures up to 20,000 psig, overcoming limitations of traditional EOS approaches and single-component CO₂ models.
Compositional Gradients
PVTP models compositional variation with depth in reservoirs where gravity segregation affects fluid properties. It generates depth-dependent EOS-based compositions, enabling more accurate reservoir characterisation across thick or heterogeneous structures.
Wax Formation
PVTP predicts wax deposition and operating envelopes using thermodynamic models based on Gibbs free energy changes, including modified versions of Won, Chung, and Pedersen models. It estimates both onset conditions and deposition volumes under varying pressure and temperature.
3-Phase Flash Calculations
PVTP includes advanced two- and three-phase flash calculations using methods such as Soreide–Whitson and Hydrafact models. A proprietary “Pseudo Multi Phase” algorithm accelerates computation while retaining accuracy, enabling practical use in large-scale simulations.
Salt Precipitation
PVTP models salt deposition caused by pressure and phase changes in water-saturated gas systems. It predicts conditions and quantities of precipitation based on brine composition or salinity, supporting assessment of production risks.
Hydrates
PVTP includes industry-standard and research-based hydrate models to predict formation conditions and operating envelopes. It also evaluates inhibitor type and dosage to support safe production and flow assurance design.
