Abstract:
A Christmas tree may include a body and a sleeve. The body may include a production flowbore therethrough, a longitudinal flowbore intersecting the production flowbore, and optionally one or more annulus passageways, crossover passageways, or chemical injection passageways intersecting at least one of the production flowbore and the longitudinal flowbore. The sleeve may be attached to and circumferentially rotatable about at least a portion of the body and may include a transverse flowbore therethrough. An annular fluid gallery may be formed between the body and the sleeve. At least one of the longitudinal flowbore and the one or more annulus passageways, crossover passageways, or chemical injection passageways may include a flowpath connecting to the annular fluid gallery or is configured to be connected to a flowpath connecting to the annular fluid gallery.
