Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

WHAT IS CLAIMED IS;

1. A system, comprising:

a tubing hanger positioned in a wellhead housing;

a production tubing string coupled to mid extending from the tubing hanger into a well·, a flowline connection body fluidly coupled to Be tubing hanger and disposed atop the wellhead homing; and

at least one primary production barrier valve disposed along a production flowpath within the tubing banger,

2. The system of claim 1, further comprising a barrier valve disposed along an annulus flowpath within the tubing hanger,

3. The system of claim I, farther comprising a second primary production harrier valve disposed upstream of the tubing hanger along a main production flowbore of the production tubing string.

4. The system of claim 1, wherein the flowline connection body further comprises:

a production swab valve disposed along a production flowpath within the flowline connection body, wherein the production swab valve provides vertical access to Be production flowpath within the flowline connection body;

a production wing valve disposed along the production flowpath witiun the flowline connection body downstream from the at least one primaiy production barrier valve;

a pressure control valve disposed along the production flowpath within the flowlme connection body downstream of the production wing valve; and

a process shut down valve disposed along the production flowpath within the flowline connection body downstream of the pressure control valve.

5. The system of claim 4, wherein the flowline connection body further comprises:

an annulus swab valve disposed along an annulus flowpath within the flowline connection body, wherein the annulus swab valve provides vertical access to the annulus flowpath within the flowline connection body; and

an annulus wing valve disposed along the annulus flowpath within the flowfine connection body downstream from an annulus flowpath within the tubing hanger.

6. The system of claim 5, wherein the flowline connection body further comprises a crossover valve disposed between the production flowpath within the flowline connection body and the annulus flowpath within the flowlme connection body.

?. The system of claim 1 , further comprising a jumper and a manifold, wherein the jumper couples the manifold to the flowline connection body.

8. The system of claim l, further comprising:

a barrier valve disposed along an annulus flowpath within the tubing hanger;

a second primary production barrier valve disposed upstream of the tubing hanger along a main production flowbore of the production tubing string;

a crossover valve disposed between the production flowpath and the annulus flowpath within the tubing hanger;

a production wing valve disposed along the production flowpath within the tubing hanger; and

an annulus wing valve disposed along an annulus flowpath within the flowlme connection body.

9. The system of claim 8, further comprising:

a flow module coupled to the flowline connection body via a first jumper; and

a manifold coupled to the flow module via a second jumper.

10. The system of claim 9, wherein the flow module further comprises a pressure control valve and a process shut down valve.

11. The system of claim 8, wherein the flowlme connection body comprises:

a production swab valve disposed along a production flowpath within the flowline connection body, Wherein the production swab valve provides vertical access to the production flowpath within the flowlme connection body; and

an annulus swab valve disposed along the annulus flowpath within the flowline connection body, wherein the annulus swab valve provides vertical access to the annulus flowpath within the flowline connection body.

12. The system of claim 1, wherein the flowline connection body does not include a primary production barrier valve capable of shutting in the well.

13. A system, comprising;

a tubing hanger positioned in a wellhead housing;

a production tubing string coupled to and extending from the tubing hanger into a well; a flowline connection body fluidly coupled to the tubing hanger and disposed atop the wellhead housing; and

at least two primary production harrier valves located upstream of the tubing hanger.

14. The system of claim 13, further comprising a barrier valve disposed along an annulus flowpath within the flowline connection body.

15. The system of claim 13, further comprising an annular access valve disposed along an annulus flowpath within the tubing hanger.

16. The system of claim 13, further comprising a production swab valve disposed along a production flowpath within the flowline connection body.

17. 'Che system of claim 13, further comprising a flow module coupled to and disposed above the flowline connection body, wherein the flow module comprises:

a production wing valve disposed along the production flowpath within the flow module; a crossover val ve disposed along the annulus flowpath within the flow module, wherein die annulus flowpath within the flow module couples to the production flowpath within the flow module downstream of the production wing valve;

a pressure control valve disposed along the production flowpath within the flow module downstream of the production wing valve; and

a process shut down valve disposed along the production flowpath within the flow module downstream of the pressure control valve.

18. The system of claim 17, wherein the flow module further comprises a third primary production harrier valve.

19, The system of claim 17, further comprising a jumper and a manifold, wherein the jumper couples the manifold to the flow module.

20. The system of claim 13, wherein the flowline connection body does not include a primary production barrier valve capable of shutting in the well.
