A REVIEW ON SMART WELL COMPLETION SYSTEM: ROUTE TO THE SMARTEST RECOVERY.

Drilling and completion techniques in petroleum industries have advanced significantly over the last few decades to improve the recovery from hydrocarbon reservoirs. The conventional method of drilling followed by well completion is replaced by various intelligent ways, which effectively support the production improvement. Smart well completion is one of these intelligent or modern techniques that include permanent downhole sensors and surface-controlled downhole flow control valves, allowing to record, evaluate, and actively manage production in real time without any well interventions. In addition, Smart wells provide the ability to control uncertainties associated with reservoir heterogeneity. These mitigate unexpected sand production due to fractures and hence increase the ultimate recovery. The design, selection and installation of different tools and equipments in a smart well completion are conducted in an effective manner so that the wells can be brought into production within the operator's objectives for the field development. Once a smart well is developed, valves can be used to independently control each segment/branch of the well in a reactive mode, such as shutting off a zone when it starts producing water; or in a defensive mode, which requires a prior determination of valve settings. The smart well system is comprised of different downhole sensors and valves which facilitate to improve the performance of the well, literally signifies the improvement of productivity and bypassing different unwanted occurrences. Various objectives are served like water cut minimization, and net present value maximization. Besides the sand production can also be minimized which causes serious distortion in the production scenario. So the intelligent completion method of production well can destine towards a logical and effective stability. In this paper, the completion system of a smart well is reviewed and presented with its pros and cons. The proper arrangement structure is furnished here which will be helpful to get a clear idea about the smartest completion outlook and can be effectively used for further practical applications.
