PVTLIB®
Black oil/compositional properties
Increased accuracy of reservoir and production engineering calculations
Without precise fluid pressure, volume and temperature properties, you risk inaccuracy in your petroleum reservoir and production engineering calculations. PVTLIB enhances your accuracy by calculating physical properties for gas, oil and water petroleum fluids. Get more precise answers with two equations of state for compositional analysis, and tap into one of the industry's most extensive libraries of empirically derived models, offering more than 140 PVT correlations for oil, gas, condensate and water.

Quick, accurate calculations
PVTLIB offers a comprehensive, empirical set of site-specific PVT property correlations, allowing you to generate accurate calculations - even when only minimal data is available. The software's ease of use lets you quickly derive answers you can trust for production and reservoir engineering problems. And with direct import links to IHS's PERFORM®, OilWat®/GasWat®, SubPUMP® and Pipesoft-2®, you add even more efficiency to your final reserves/production reporting.
More flexibility with two equations of state
PVTLIB calculates physical properties and vapor-liquid equilibrium of hydrocarbon mixtures using two equations of state: Redlich-Kwong-Soave (RKS) and Peng-Robinson (PR). Two methods offer added flexibility and accuracy in calculating reserves and production in complex multiphase fluid environments. You can also calculate for a full single stream or two separate streams, vapor and liquid, or choose from as many as 17 components, including psuedo-components (hypotheticals), impurities (CO2, H2S, N2) and water.
Detailed calculations with PVT property templates
With a suite of regionally specific empirical PVT property templates, you can create detailed PVT calculations and analysis using black oil correlations, laboratory separator data, flash liberation data, differential liberation data and equations of state. Lab data is shown together with calculated properties to "visually" check accuracy of correlations against measured data.
"PVTLIB helps me accurately model fluid properties, using either black oil or compositonal methods. I have access to 140+ PVT correlations so I can model any fluid from around the world. I can also export results to other IHS engineering applications, which enhances the accuracy of calculations. "

Graphical capabilities
PVTLIB's many graphical capabilities help you reach faster, more reliable conclusions. You can plot and compare different correlations on a single graph, as well as produce numerous output graphs, including a phase-envelope graph for compositional cases. You can also overlay multiple correlations for the same fluid component (i.e. FVF) on a single plot and compare/contrast answers between correlations. PVTLIB also features different units systems, including custom-defined by user.
