PHASE BEHAVIOUR & FLUID PROPERTY PROGRAM

PRODUCT SPECS

WinProp is a fluid property characterization application for creating tuned fluid property descriptions for IMEX™, GEM™ and STARS™, plus black oil fluid property data for 3rd-party reservoir simulation software. WinProp can be used for:

� Component characterization

� PVT matching

� Miscibility studies

� Modelling of laboratory experiments

� Prediction of wax and asphaltene production

� Surface separation facilities modelling

� Generation of PVT data for CMG simulators

WinProp incorporates a user friendly graphical interface that makes preparing data and interpreting results more effective and efficient.

BENEFITS

� Tune EoS to accurately match laboratory analysis results and predict fluid behaviour

� Understand property distribution within a reservoir fluid system, under different depletion scenarios

� Improve understanding of reservoir exploitation process

WinProp™ is an essential tool for reservoir engineers, both in the laboratory and in the field, to accurately identify and model the phase behaviour and properties of reservoir fluids. It has proven its value for multi-phase and special processes, and where compositional variations exist. WinProp is an integral component in advanced reservoir simulation modelling.

MULTIPLE EoSIt is often difficult for a single EoS description to perform adequately over a wide range of conditions encountered in reservoir phase behaviour modelling. This can be alleviated by the introduction of a second EoS model that is applied to calculations performed at surface (separator) conditions, while the first EoS set is used for calculations at reservoir conditions. Therefore, separator data can then be matched separately from other PVT data gathered at reservoir temperature, for example by CVD and differential liberation experiments.

AQUEOUS PHASE PROPERTIESUsing Henry’s Law, WinProp models the solubility of CO

2, H

2S, and light hydrocarbons in water of varying salinity.

Water content of gases is also predicted accurately. WinProp contains an extensive library of geochemical reactions for rock mineralogy interaction with the aqueous phase for output into GEM reservoir simulator.

ASPHALTENE AND WAX PRECIPITATION MODELLINGWinProp has a multi-component solid solubility model coupled with the EoS for description of asphaltene or wax precipitation. WinProp models the precipitate as a multi-component solid. It also handles non-isothermal conditions and allows up to three fluid phases in equilibrium with the precipitate. Save time with the easy to use model that has few adjustable parameters and requires minimal experimental data.

MISCIBILITY PREDICTIONWinProp’s multiple contact miscibility option calculates condensing, vaporizing, or condensing-vaporizing drives. Based on user-defined lumping schemes, WinProp creates ternary diagrams to graphically interpret the miscibility mechanism. The minimum miscibility enrichment level allows calculation of the minimum fraction of rich gas required to be added to a lean gas stream to achieve multi-contact miscibility with oil at a specified pressure and temperature.
