Abstract (en)
A system (10) includes a distributed control system (20) and a subsea tree (56) that includes subsea tree chokes (136) and a subsea control module (38) communicatively coupled to flow control valves (126). The distributed control system (20) communicatively couples to the subsea control module (38), is located at a surface level, and includes processors (27) that send a first instruction to the flow control valves (126) to adjust hydrocarbon production flow when water or gas cut is above a threshold. The processors (27) 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.
