Gas transport in nanoscale channels that have perfectly flat walls has been found to be frictionless, challenging the classical theory of gas flow. The findings might enable new devices for gas ...

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 ...

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 ...
