Gas wells need a minimum flow rate to lift liquid droplets to the surface—this is the critical velocity, where drag and gravity forces balance.
If the rate drops below this, liquids build up in the wellbore, leading to loading issues that affect production.
This Excel tool calculates the critical lift rate (Qcr) using the Turner and Coleman correlations, both widely used in the industry. It has a simple interface for quick data input and clear results.
A PVT correlations library runs in VBA to estimate fluid properties, and results are shown in an interactive chart, plotting Critical Lift rate as a function of pressure.
