SYSTEMS AND METHODS FOR STARTING, RESTARTING, MONITORING AND INCREASING PERFORMANCE
OF A PRODUCTION AND/OR INJECTION SYSTEM |
(57) 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.
