PVT fluid properties calculator

PVT calculator software at pengtools.com

PVT calulator 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
