Abstract

A smart in-situ gas lift is the latest emerging technology in the oil and gas production. This intelligent system requires the reservoir to have high amount of gas supply either from reservoir’s gas cap itself or another gas formation. The aim of this study is to select the design consideration for smart in-situ gas lift. Theoretical analysis, simulation and also field applications have been critically reviewed to notice their effects on the field development and production strategy. Compared to conventional gas lift design, four main design factors have been addressed namely interval control valves (ICV), well selection, valve setting depth and valve opening. To further validate the effectiveness of the smart in-situ gas lift, the design has been applied on a well which is located in L-Field. The application of smart in-situ gas lift show great improvement to the productivity of the well when the natural production rate has increased up to 27% compared to the impact of conventional gas lift on natural production rate which has increased about 11% from natural production rate. Plus, the implementation of smart in-situ gas lift has maximized the production of oil from reservoir that characterize by large gas cap size. This paper generally endorses the fact that in situ gas lift method gives big advantage in extending the well life even at high water cut and reducing the high cost of installing expensive gas lift infrastructures in the conventional gas lift system.
