PVT & Phase Behavior
PVT has an impact on essentially every discipline in the petroleum domain. However, utilizing and accessing PVT information can be costly, impractical and time-consuming. whitsonPVT streamlines the access to both PVT data and models throughout an organization. Every PVT report, black oil table, fluid initialization model or gas-EOR calculation is centralized in one place. We like to think about it as a living document for PVT data and models that ensures consistency and enables collaboration across an organization.
- Fluid definition from limited field data (API & GOR)
- BO Table Generation and Extrapolation
- BOT and EOS Model Export to Any Platform
- Gas EOR Module (Miscibility, Huff-n-Puff)
- Database of PVT Reports, Sampling & Fluid Storage
Production Data Diagnostics
Generate daily wellstream compositions based on readily available field-measured data, leveraging an EOS model. These wellstream compositions are used for multiple relevant engineering calculations, such as separator shrinkage factor calculations (sales oil recovery factor), converting GORs for changing separator conditions, and separator process optimization. Other engineering applications include the analysis of emissions & air quality, well classification (for royalty & tax purposes), as well as the correct allocation of sales products to individual wells.
- Compositional Tracking
- Separator Oil Shrinkage (Sales Oil Volume)
- Common Process Conversion
- Separator Optimization
- Gas Condensate Diagnostics
Bottomhole pressures are required in many reservoir- and production engineering aspects, such as history matching, RTA/PTA, IPR estimation, and more. Based on production data measured at the surface (i.e. surface rates, and wellhead pressure and temperature), and key properties describing the wellbore (i.e. a deviation survey describing the curvilinear shape of the well, wellbore diameter, and pipe roughness), we can estimate the bottomhole pressure through several commonly used correlations.
- Multiphase flow wellbore calculations
- Multiple correlations (Beggs and Brill, Hagedorn and Brown, Gray, Woldesamayat and Ghajar)
- Uncertainty range of BHP calculation based on different correlations
- Consistent handling of shut-well BHP calculation

Our Consultancy Services
Understanding petroleum fluids is fundamental to maximizing the profitability of oil and gas assets, as the fluids are what we produce, and what we sell. An equation of state (EOS) model is one of the most sophisticated technologies available to describe these petroleum fluids. We have over the last 30+ years specialized in EOS model development and fluid characterization. Our EOS development projects generally involve multiple fluid samples from different wells.

- EOS Model Development
- Black Oil Table Generation

Gas Condensate Reservoirs
whitson gas condensate services include topics related to PVT, condensate blockage, and simulation of well productivity, depletion and gas cycling using black-oil and EOS reservoir models. We work with all PVT laboratories on design, QC and interpretation of conventional and special gas condensate PVT studies. We develop EOS and black-oil PVT models with special emphasis on gas condensate issues like CGR variation, condensate blockage and gas cycling EOR. Together with Stratum Reservoir (Trondheim Lab) we quantify near-well flow leading to blockage; whitson designs and interprets the lab tests, then develops velocity-dependent relative permeability models.

- Relative Permeability Modeling
- Condensate Blockage Modeling
- Gas Cycling / EOR
- EOS & Black Oil PVT Modeling
Enhanced oil recovery with gas injection is a commonly used strategy to increase the recovery from existing oil and gas fields. We assist our clients in both conventional and unconventional assets in addressing the challenges related to the implementation and operation of gas EOR projects, specifically assisting in selection of wells for injection, design of injection strategy (number of wells, injection pressures & volumes), and history-matching once the EOR has been started.
