Abstract

A well test burner system includes a plurality of burner nozzles, each including an air valve and a well product valve movable between an open position, where air and a well product are allowed to circulate through the burner nozzle to discharge an air/well product mixture, and a closed position, where the air and the well product are prevented from circulating through the burner nozzle. One or more actuation devices are operatively coupled to the air valve and the well product valve to move the air valve and the well product valve between the open and closed positions.

Claims

1. A well test burner system, comprising:

a plurality of burner nozzles, each including an air valve and a well product valve movable between an open position, where air and a well product are allowed to circulate through the burner nozzle to discharge an air/well product mixture, and a closed position, where the air and the well product are prevented from circulating through the burner nozzle; and

one or more actuation devices operatively coupled to the air valve and the well product valve of each burner nozzle to move the air valve and the well product valve between the open and closed positions, wherein the one or more actuation devices comprises a rotatable cam plate.

2. The well test burner system of claim 1, wherein the plurality of burner nozzles is arranged in a circular array, the well test burner system further comprising:

an air inlet manifold extending about the circular array;

an air inlet pipe extending radially between the air inlet manifold and each burner nozzle to provide air to the plurality of burner nozzles;

a well product inlet manifold; and

a well product inlet pipe extending between the well product inlet manifold and each burner nozzle to provide a well product to the plurality of burner nozzles.

3. The well test burner system of claim 1, wherein the plurality of burner nozzles is arranged in a circular array and the rotatable cam plate comprises:

a circular body that defines a planar face extending between a central aperture defined in the body and an outer periphery of the body;

one or more outer radial lobes protruding from the planar face at a first radius from a center of the body to radially align with the air valve of each burner nozzle; and

one or more inner radial lobes protruding from the planar face at a second radius from the center to radially align with the well product valve of each burner nozzle.

4. The well test burner system of claim 3, wherein the one or more outer and inner radial lobes are angularly aligned with respect to each other to simultaneously engage the air and well product valves, respectively.

5. The well test burner system of claim 3, further comprising a transition surface defined at one or both arcuate ends of the outer and inner radial lobes.

6. The well test burner system of claim 3, wherein the one or more outer radial lobes exhibit an outer arcuate length and the one or more inner radial lobes exhibit an inner arcuate length that is shorter than the outer arcuate length such that, as the cam plate rotates, the one or more outer radial lobes engage the air valve of a given burner nozzle before the one or more inner radial lobes engage the well product valve of the given burner nozzle, and the one or more outer radial lobes disengage the air valve of the given burner nozzle after the one or more inner radial lobes disengage the well product valve of the given burner nozzle.

7. The well test burner system of claim 3, wherein each air valve and each well product valve provides a head and a stem that extends longitudinally from the head, and wherein the one or more outer radial lobes engage the stem of each air valve to move the air valve between the open and closed positions and the one or more inner radial lobes engage the stem of each well product valve to move the well product valve between the open and closed positions.

8. The well test burner system of claim 3, further comprising a motor operatively coupled to the cam plate to rotate the cam plate in either angular direction.

9. The well test burner system of claim 1, further comprising a compression spring coupled to each air valve and each well product valve of each burner nozzle, the compression spring exhibiting a spring force that urges the air valve and the well product valve to the closed position.

10. The well test burner system of claim 1, wherein the one or more actuation devices comprises a plurality of actuation devices, and each air valve and each well product valve is independently and selectively operated by an individual actuation device of the plurality of actuation devices.

11. The well test burner system of claim 10, wherein each air valve and each well product valve provides a head and a stem that extends longitudinally from the head, and wherein the individual actuation device of each air valve and each well product valve engages the stem to move the air valve and the well product valve between the open and closed positions.

12. The well test burner system of claim 10, wherein the plurality of actuation devices comprises an actuator selected from the group consisting of a mechanical actuator, an electromechanical actuator, a hydraulic actuator, a pneumatic actuator, and any combination thereof.

13. The well test burner system of claim 10, further comprising a computer communicably coupled to the plurality of actuation devices to selectively actuate the plurality of actuation devices.

14. A method, comprising:

supplying air and a well product to a plurality of burner nozzles, each burner nozzle including an air valve and a well product valve; and

actuating the air valve and the well product valve of each burner nozzle between an open position and a closed position with one or more actuation devices operatively coupled to the air valve and the well product valve of each burner nozzle, wherein the actuation device comprises a rotatable cam plate,

wherein, when the air valve and the well product valve are in the open position the air and the well product circulate through the burner nozzle and discharge an air/well product mixture, and

wherein, when the air valve and the well product valve are in the closed position the air and the well product are prevented from circulating through the burner nozzle.

15. The method of claim 14, further comprising:

opening the air valve of a given burner nozzle prior to opening the well product valve of the given burner nozzle; and

closing the air valve of the given burner nozzle after closing the well product valve of the given burner nozzle.

16. The method of claim 14, wherein the plurality of burner nozzles is arranged in a circular array and the rotatable cam plate comprises one or more outer radial lobes and one or more inner radial lobes, the method further comprising:

rotating the cam plate;

engaging the air valve of each burner nozzle with the one or more outer radial lobes as the cam plate rotates and thereby moving the air valve of each burner nozzle between the open and closed positions; and

engaging the well product valve of each burner nozzle with the one or more inner radial lobes as the cam plate rotates and thereby moving the well product valve of each burner nozzle between the open and closed positions.

17. The method of claim 16, wherein the one or more outer and inner radial lobes are angularly aligned with respect to each other, the method further comprising simultaneously engaging the air valve and the well product valve of each burner nozzle with the one or more outer and inner radial lobes, respectively.

18. The method of claim 16, further comprising:

engaging the one or more outer radial lobes on the air valve of a given burner nozzle before the one or more inner radial lobes engage the well product valve of the given burner nozzle; and

disengaging the one or more outer radial lobes from the air valve of the given burner nozzle after the one or more inner radial lobes disengage the well product valve of the given burner nozzle.

19. The method of claim 14, wherein the one or more actuation devices comprises a plurality of actuation devices, the method further comprising independently operating each air valve and each well product valve with an individual actuation device of the plurality of actuation devices.

20. The method of claim 19, wherein the plurality of actuation devices is communicably coupled to a computer, the method further comprising sending command signals to the plurality of actuation devices to selectively actuate the air valve and the well product valve of each burner nozzle.
