The production influx changes from reservoir into the wellbore, this fluctuation is considered to be the main source of problems caused in the production management. The reason is difference between mobility of water and oil. As water is less viscous than oil, it flows faster than oil. The high water production rate requires larger water treatment facilities ultimately increasing the operating cost, meanwhile there is lesser provision for these facilities in offshore setup. In this paper it is described, how advanced well completion equipped with autonomous inflow control devices AICDs increases oil production while reducing water flow rates even after water breakthrough. The compatibility of AICDs is evaluated for better water production management in mature fields. In order to counter these problems a simulation study is required to design the well completion along with the required number of packers, devices and their sizes. The inflow control technology is capable to create higher or lower drawdown on the reservoir in order to assure the maximum flow of oil while restricting water to flow through. Autonomous ICDs proved to be the best inflow control devices and are efficient to be used in well with very high water cuts i.e. up to 90%. This study shows the application of AICDs for production optimization and reduction of water cuts in mature oil fields.
