Critical Lift Rate - Excel Calculator

Gas wells need a minimum flow rate to lift liquid droplets—this is the critical velocity, where drag and gravity balance. If the rate drops, liquids accumulate, leading to loading issues.

This Excel tool calculates the critical lift rate (Qcr) using the Turner and Coleman correlations. It features a simple interface, a built-in PVT correlations library, and an interactive chart that plots Qcr against pressure for quick analysis.
