This is an important tool for Oil and Gas. By using it and sharing your experience with your friends you are contributing to the viability of this project. thanks

This app is a tool very useful for complex calculations of the gas compressibility factor Z for natural gases used in the Gas Law: PV = nRTZ. Formulas by Hall and Yarborough (1973) correlation to estimate z-factor of natural gas.

Standing and Katz’s Chart to Z-Factor vs Reduced Pressure and Reduced Temperature was plotted by app using formulas by Hall and Yarborough (1973).

What’s New

Version 2.1

- improved iPad 11 version to run on Mac M series (designed for Mac)

new features based on user requests:
- current pseudo-reduced temperature highlighted in the Z-factor graph
- on moving your finger on the graph shows the Z factor versus the gas pressures for the current gas temperature
- added options to select units and set decimals
