Abstract
Production from a subsea wellhead to a floating production facility may be realized with the use of a substantially neutrally buoyant flexible production riser which includes biasing means for shaping the riser in an oriented broad arc. The broad arc configuration permits the use of wireline well service tools through the riser system.
Claims2
In a system for the production of hydrocarbon fluids from a subsea well including at least one well head having a riser connection, a moored, floating production vessel located at the surface of the body of water, and at least one flexible production riser extending between said well head riser connection and said vessel, said flexible riser being substantially neutrally buoyant and further including biasing means on said riser for shaping said riser in an oriented, broad arc, said biasing means including a control bundle disposed on one side of said riser bundle, whereby the passage of gravity-motivated wireline well service tools between said vessel and said well is permitted.
