bstract Increased hydrocarbon recovery and accelerated production from ultra-high water mobility oil-wet reservoir requires the application of advanced well completion technologies to address premature water breakthrough, reservoir management, production management and extended reservoir contact from a single well location. The Burgan Reservoir of Minagish Field, West Kuwait has active aquifer, very high permeability sands associated with active faults and contain highly viscous reservoir fluid with downhole viscosity of 40cp, enhances water mobility and resulted in premature water breakthrough with increasing water cut trend within few months of production as confirmed from well performance of existing horizontal wells. This has resulted in to nonuniform reservoir depletion, by-passed oil regions and low oil recovery. The Kuwait’s first smart level-4 multilateral well was completed in

Burgan reservoir by combining the Level-4 junction along with stacked dual lateral completion having customized viscosity independent Inflow Control Device (ICD), customized two Inflow-Control Valves as well as down hole gauges, wide operating range Electrical Submersible Pump (ESP), suitable wellheads, X-MAS tree and Integrated surface panel for real time data monitoring. The smart multilateral well has assisted in addressing premature water breakthrough, enhanced dry oil production and facilitated uniform depletion, which results in improved hydrocarbon recovery. The paper covers the customized design of smart Level-4 multilateral well by taking in to account the reservoir and its fluid characterization, well architecture, implementation and specially designed invert emulsion drilling fluid for effective wellbore cleanup to achieve formation virginity. The improved reservoir management and production management results are also mentioned in this paper.

Introduction The advance smart multilateral well equipped with Inflow Control Device (ICD) and Inflow Control Valve (ICV) along with downhole gauges is identified as the optimum solution to accelerate oil production rate, maximize reservoir contact from a single well location and achieve adequate proactive reservoir management as well as production management to maximize oil recovery in high water mobility Burgan reservoir of Minagish field, West Kuwait. The Minagish field located in the West Kuwait (figure 1) is a north-south trending anticline with hydrocarbon contained in six major reservoirs ranging in age from early Jurassic to late Cretaceous and consists of both sandstone and carbonate reservoirs. The Burgan sandstone reservoir is lying at the crest of Minagish Field. The lower part of reservoir consists of massive channel sand and the upper part of reservoir contains vertically stacked thin laminated sand bodies with extensive lateral facies variation (figure 2).
