Dual Subsea Production Chokes for HPHT Well Production
摘要:
Configurations and methods for subsea hydrocarbon production at high pressure wells are contemplated in which production control is achieved by implementing two choke valves in series between the wellhead and the riser The first production choke reduces pressure from well pressure to a reduced pressure, while the second production choke further reduces the pressure from the reduced pressure to riser pressure. The first production choke is preferably coupled to the production tree, and the second production choke is coupled to production tree, a subsea pipeline-end device (e.g., PLET or PLEM), a well jumper, or a flowline jumper.
