Gas Properties Download

Click highlights to download macro-enabled Excel workbooks "Gasprops" or "BHFP-Unload".


Two pseudo-critical properties worksheets are included depending upon availability of gas composition or specific gravity.

“Gasprop” calculates standard gas properties, pseudo-pressure, and pseudo-pressure with k(p)
“BHP” calculates a flowing bottom-hole pressure from surface pressure using Cullender and Smith or Hagedorn and Brown.
“Unload” uses the well known Turner method to calculate the minimum gas rate for continuous liquid removal.


I coded using VBA and the modules are not password protected --modify as you see fit. I have used since 2003 without problems but make no guarantees. Use at your own risk.
