Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

Precisely formulated gas mixtures with known concentrations of particular target gases are referred to as calibration gas standards. To guarantee the accuracy of gas concentration measurements, almost ...

A new empirical correlation can help engineers size chokes for controlling gas-condensate production and predicting the performance of flowing wells under different conditions. The correlation was ...
