Abstract: A system includes a distributed control system and a subsea tree that includes subsea tree chokes and a subsea control module communicatively coupled to flow control valves. The distributed control system communicatively couples to the subsea control module, is located at a surface level, and includes processors that send a first instruction to the flow control valves to adjust hydrocarbon production flow when water or gas cut is above a threshold. The processors also send a second instruction to the subsea tree chokes to adjust the flow of the production when a quality of commingling of the production flow with additional production flows is less than a threshold, an arrival pressure is less than a threshold, or an arrival flow rate is less than a threshold. The processors further continue the production of the fluids with current settings when a production rate is above a production rate threshold.

Abstract: A system, method and program product for analyzing multiphase flow in a wellbore. A system is provided that includes: an input system for receiving pressure and temperature readings from a pair of sensors located in the wellbore; a computation system that utilizes a flow analysis model to generate a set of wellbore fluid properties, wherein the set of wellbore fluid properties includes at least one of: a fluid mixture value, a phase velocity value, a flow rate, a mixture density, a mixture viscosity, a fluid holdup, and a slip velocity; and a system for outputting the wellbore fluid properties.
