Abstract: A well has an outer housing with a vertical main bore and a wing bore. The well is completed by: running an upper completion into the well; locating a tubing hanger in the main bore of the outer housing for fluid communication with the wing bore, the tubing hanger including a services line connected to downhole equipment; connecting a further services line to the services line of the tubing hanger, after the tubing hanger has obtained said operational position; and installing a cap on an end of the main bore. The connected services lines are arranged to communicate a service between the tubing hanger and an exterior of the capped well through either or both of: the end of the main bore; and the cap. Related apparatus, a cap, and a tubing hanger are also described.

Abstract: A method is for constructing a subsea well and an associated unit. The method may include: providing a unit having at least one component of a flow control assembly, the flow control assembly to be operable for controlling a flow of injection or production fluid during operation of the well after the well has been constructed; lowering the unit through sea toward a seabed; receiving part of the unit in a subsurface of the seabed to anchor the unit in place, part of the unit projecting above the seabed, whereby the component of the flow control assembly is positioned in the projecting part; and performing at least one well construction operation through a bore in the unit.
