New approach calculates deepwater gas-lift valve dome pressure

Click here to enlarge imageA new approach for calculating the dome pressure for nitrogen-charged, gas-lift valves placed in deepwater wells provides more general and precise numerical values than previous correlations.The need for tables can be avoided with the new approach because it does not depend on test-rack temperature. Moreover, it is especially suited for computer applications because its analytical feature ensures low computational cost.Gas liftGas lift is one of the most important artificial lift methods, especially for offshore wells. In this method, gas at a high pressure is injected into the tubing or tubing-casing annulus, and its flow rate, during kick-off or production p...
