Abstract
A system, in some embodiments, for producing well production fluids through a tubing hanger connected with a production tubing string. The system includes a subsea tree with a production flow passage and a tree annulus flow passage. The system also includes a spool assembly separate from the subsea tree that includes a body with a longitudinal passage configured to receive and support the tubing hanger, there being an annulus between the production tubing string and the body. The spool assembly also includes a lateral flow passage extending from the spool longitudinal passage and configured to transfer the production fluids. Further, the system includes an annulus flow passage extending externally from the spool assembly and in fluid communication with the annulus.
Claims12
A system for producing well production fluids through a tubing hanger connected with a production tubing string, comprising:
- a subsea tree comprising a production flow passage and a tree annulus flow passage;
- a spool assembly separate from the subsea tree and comprising:
- a body comprising a spool longitudinal passage configured to receive and support the tubing hanger, there being an annulus between the production tubing string and the body;
- and
- a lateral flow passage extending laterally from the spool longitudinal passage and configured to transfer the production fluids to the production flow passage;
- and
- an annulus flow passage in fluid communication with the annulus and extending externally from the spool assembly at a first location and reentering the spool assembly at a second location separate from the lateral flow passage.
A system for producing well production fluids with a tubing hanger supporting a tubing string with an annulus surrounding the tubing string, and a subsea tree, the system comprising:
- a spool assembly comprising:
- a spool longitudinal passage configured to receive and support the tubing hanger;
- and
- a lateral flow passage extending laterally from the spool longitudinal passage and configured to transfer the production fluids to the subsea tree;
- and
- an annulus flow passage in fluid communication with the annulus and extending externally from the spool assembly at a first location and reentering the spool assembly at a second location separate from the lateral flow passage.
A system for producing or injecting fluids into a well using a tubing string with an annulus surrounding the tubing string, comprising:
- a subsea tree comprising a production flow passage and a tree annulus flow passage;
- a spool assembly separate from the subsea tree and comprising:
- a body comprising a spool longitudinal passage;
- and
- a spool lateral flow passage extending laterally from the spool longitudinal passage and configured to transfer the fluids to the production flow passage;
- a tubing hanger landable within the spool longitudinal passage and comprising:
- a hanger longitudinal passage;
- and
- a hanger lateral flow passage in fluid communication with the hanger longitudinal passage and the spool lateral flow passage;
- and
- an annulus flow passage in fluid communication with the annulus and extending externally from the spool assembly at a first location and reentering the spool assembly at a second location separate from the spool lateral flow passage.
