Field conditions, valid information, and good initial planning become very important in the success of flow assurance management activities, particularly in <br /> <br /> <br /> deepwater operation. Low deep water temperature environment and limitations on installation as well as maintenance of production facilities at sea, make problems that occurred in deepwater is more complicated compared to operation in onshore. So that the mistake in early planning design of facilities which used in <br /> <br /> <br /> deepwater operation, will lead to less optimal production or might be able to jeopardize the sustainability of field production. This study creates a new model of an operating prediction curves (stable operating envelope), which provides description of the safe conditions of various problems that may occur during the hydrocarbon production in deepwater operation using flow assurance. The production problems case focuses on gas hydrate formation, wax deposition, severe slugging, maximum pipe strength and back pressure occur <br /> <br /> <br /> in the system. The developed curves provide information about safe region at various liquid rates and gas liquid ratio which may occur during operation. These curves can be applied for a new production system design. The curves are enhanced by considering the influence of various water cuts of reservoir fluid. To show the <br /> <br /> <br /> implementation of developed curves, the several case study are discussed due planning of engineered efforts to the production system. All the plans studied by <br /> <br /> <br /> one purpose, so that stable operating envelope which generated can be more optimal.
