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 ...

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 ...

In one such experiment on suspended animation, using a mixture of gases which required to be present in precise proportions within a mixture at very low flow rates, Dr. David Kraus, Ph.D. experienced ...

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 ...
