Petroleum fluids are what an E&P company sells to make money, and hence, understanding petroleum fluids is fundamental to maximizing the profitability of oil and gas assets. An equation of state (EOS) model is one of the most sophisticated technologies available to describe these petroleum fluids. We have specialized in EOS model development the last 30-40 years. When we develop EOS models, it typically involves 10s or 100s of fluid samples regionally distributed across a field or a region. These models are often referred to as either common, field-wide or basin-wide EOS models.
Approach & Methodology
- Quality check (QC) PVT laboratory reports
- C7+ characterization
- EOS Tuning to match laboratory experiments
- Thermodynamic Consistency Check of EOS
- EOS Pseudoization/lumping
- Extrapolated Black Oil Table Generation
- Fluid initialization
Deliverables
- EOS model in requested format (E300, GEM, SENSOR, HYSYS or other)
- Black oil tables in requested format (E100, IMEX, PROSPER or other)
- All digital files and results related to this work (e.g. QC)
- Final detailed report containing key findings, results and recommendations
- Final presentation
