Calculate_Gas_Rate_Using_Choke_Equation_Schlumberger_Model
This tool is useful when you want to estimate gas rate by increasing choke size during a welltest program. Suppose you want to test your gas well using separator test. You want to produce your well up to 100 MMscf/d.
Unfortunately, your separator test is limited to produce gas up to 30 MMscf/d. Using this tool you can predict your gas rate by changing the choke size. Gas rate is calculated using Schlumberger model.
To calculate gas rate, follow the following steps:

Calculate C coefficient from welltest data.
Plot Choke Size vs. C coefficient calculated above.
Generate correlation of C coefficient as a function of Choke Size using Excel trendline.
Re-calculate C coefficient using above correlation.
Calculate gas rate using new calculated C correlation.
