This paper describes a case history detailing design, planning, completions, testing and production of first Inflow Control Device (ICD) horizontal well in one of field in Middle East. In this field, most of existing wells are openhole horizontal producers. A non uniform production profile across the horizontal section can result in early water and gas breakthrough. This can substantially reduce oil production, create zones of bypassed oil and lower the ultimate recovery. In case of early water breakthrough, it will also accelerate the need for artificial lift for individual wells and require increased water and gas handling capacity requirements. The area of first row of producers located close to the water injectors are now experiencing increasing water cut in some wells causing the well to decline and die prematurely. Objective from the first ICD installation was to test the technical concept of ICD completion in managing the heel-toe effect and reduce the water cut (multiple water entries) in this well, as a first step to mitigate the down-dip and mid-dip problem. Additionally following objectives were set: reduce water cut, optimize production, extend the life of well, prove ICD technology benefits and use to field wide. A critical aspect of the process way the modeling, prediction and optimization of both reservoir performance and completion hardware design. After successful ICD design and installation, well was put on production and tested, following results are achieved: oil rate increased by 100%, Water cut reduced by 18% and well head pressure increased by 30%. The appraisal and acceptance loop of the completion has been closed by having this well completed, put on production and tested. Approval of concept was achieved and the anticipated benefits were realized by actual performance of the well. Leverage knowledge from this pilot well has provided an insight into ICD capabilities and implementation and has set the stage for other fields.
