PVT fluid properties calculator
PVT calculator software at pengtools.com is the core PVT engine of the pengtools.
PVT software calculates the main properties of oil, gas and water using a set of black-oil correlations and provides the basic input for any Petroleum Engineering calculation.
PVT software is available online at www.pengtools.com.
Typical applications
- Calculation of fluid properties for oil, gas and water.
- Generating the PVT model
- Matching the PVT model to the Lab data
- Exporting PVT tables to Excel or reservoir simulator
Main features
- Plots of PVT properties vs pressure at reservoir temperature
- Results table contains values under standard conditions and at pressures between surface atmospheric and reservoir at reservoir temperature
- "Default values" button resets input values to the default values
- Switch between Metric and Field units
- Save/load models to the files and to the user’s cloud
- Share models to the public cloud or by using model’s link
- Export pdf report containing input parameters, calculated values and plots of the PVT properties
- Continue your work from where you stopped: last saved model will be automatically opened
- Download the chart as an image or data and print (upper-right corner chart’s button)
- Export results table to Excel or other application

What to do when you need a PVT model quick? Watch our demo video on how to create a PVT model in 5 min?
In this demo we are solving the PVT exercise 11-2 of William McCain's book "The Properties of Petroleum Fluids".
