NEW APPLICATION OF GOLDEN SECTION SEARCH FOR PREDICTION OF OPTIMIZED GAS LIFT PARAMETERS
Abstract
Currently, continuous gas lift has a significant contribution for the purpose of petroleum production from those wells that have low production rates or those that have ceased their production. Therefore, production engineers are constantly finding the ways for optimizing this type of system. Superior designs are achieved when important parameters are optimized prior to system implementation. Optimization of gas injection into the annulus and also the tubing size are of the most important parameters. The functionality of these parameters with respect to the oil production rate is never differentiable and thus simple methods do not fetch up the optimum values. Heuristic approaches have been used for this reason but the timeconsuming nature of these methods has always been a drawback. This paper presents the “Golden Section Search” method for obtaining the optimum values to the gas lift optimization problem. Faster runs and the capability for approaching the solution with any given precision are of its characteristics.
