Calculate Gas Formation Volume Factor
Excel Function To Calculate Gas Formation Volume Factor
This Excel tool is very helpful to calculate gas formation volume factor (Bg). This gas properties is estimated from gas viscosity and compressibility factor that have been calculated from the previous posts. On input, you have to provide gas specific gravity (air=1), gas composition (CO2 and H2S), and temperature. Gas compressibility factor and viscosity calculations are provided in this tool. Gas formation volume factor is asymptotically approached as the pressure decrease.
Note: Gas compressibility factor is calculated using Dranchuk and Abou-Kassem equation. Gas viscosity is estimated from Lee, Gonzales and Eakin equations.
