Abstract:
1. A subsea production assembly comprising: a first production choke fluidly and in series coupled to a second production choke to control flow of a hydrocarbon production stream from a well, wherein the first and second production chokes are non-downhole production chokes, and wherein the hydrocarbon production stream flows through the first and second production chokes; wherein the first production choke is configured to reduce pressure of the hydrocarbon production stream from a subsea well from a well pressure to a reduced pressure; wherein the second production choke is configured to reduce pressure of the hydrocarbon stream from the reduced pressure to a riser pressure; wherein first and second production chokes are fluidly coupled to a wellhead in a position at or downstream of the wellhead and upstream of a riser base; and wherein the wellhead is configured to produce a high pressure fluid.
