Different correlations applied to each segment of a well bore provide better pressure-loss estimates than a single-correlation for the entire well. Four widely used multiphase-flow correlations have ...

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 ...

Replacing worn-out couplings with the incorrect size can cause unintended consequences. Flow velocity is an important consideration when replacing a larger hydraulic hose inside diameter with a ...
