Abstract

A plug that contacts both an upstream seat and a downstream seat based on a upstream spring creating first forces on the upstream seat and a downstream spring creating second forces on the downstream seat. The first forces may be in a downstream direction and the second forces may be in an upstream direction. Additionally, the upstream chamber and the downstream chambers may be dependent pistons that are configured to create dynamic forces acting upon the plug.

Claims (41)

1. A high pressure valve for oil and gas operations comprising:

a plug configured to rotate between an open position and a closed position, wherein in the open position the plug allows fracturing fluid to flow through tubing, the plug being configured to move along a linear axis when in the closed position;

a first assembly positioned upstream from the plug, the first assembly including a first seat positioned upstream from the plug and configured to contact the plug, the first seat being configured to move along the linear axis based on receiving forces from the plug, the first assembly including a first chamber configured to generate a first force against the first seat;

a second assembly positioned downstream from the plug, the second assembly including a second seat positioned downstream from the plug and configured to contact the plug, the second seat being configured to move along the linear axis based on movement of the first seat and receiving forces from the plug, the second assembly including a second chamber configured to generate a second force against the second seat;

a conduit directly extending from the first chamber to the second chamber, wherein fluid flows through the conduit to control the first force and the second force responsive to movement of the plug on the linear axis and the first seat or second seat receiving the forces from the plug, wherein the first force is inversely related to the second force.

2. The high pressure valve of claim 1 , wherein a first volume of fluid within associated with the first chamber is dependent on a second volume of fluid within the associated with a second chamber, wherein the first volume and the second volume dynamically change.

3. The high pressure valve of claim 1 , wherein the first force exerted by the first piston being is dependent on the second force.

4. The high pressure valve of claim 1 , wherein:

the conduit extends across the plug.

5. The high pressure valve of claim 4 , wherein the conduit provides a closed fluid path between the first chamber and the second chamber.

6. The high pressure valve of claim 1 , further comprising:

hydraulic fluid that is configured to move between the first chamber and the second chamber, wherein a total amount of the hydraulic fluid within the first chamber and the second chamber does not change.

7. The high pressure valve of claim 6 , wherein responsive to moving a portion of the hydraulic fluid from the second chamber to the first chamber, the first force will increase and the second force will decrease.

8. A high pressure valve comprising:

a plug configured to rotate between an open position and a closed position, wherein in the open position the plug allows fracturing fluid to flow through tubing;

a first assembly positioned upstream from the plug, the first assembly including a first seat positioned upstream from the plug and configured to contact the plug, the first seat being configured to move along a first linear path;

a second assembly positioned downstream from the plug, the second assembly including a second seat positioned downstream from the plug and configured to contact the plug, the second seat being configured to move along the first linear path based on movement on the first seat;

a conduit that is configured to allow fluid communication between the first chamber and the second chamber, the conduit extending across the plug;

an external piston in fluid communication with the conduit, the external piston including a first side and a second side, the first side being configured to receive the fracturing fluid to move the external piston.

9. The high pressure valve of claim 8 , wherein when the external piston moves a total amount of hydraulic fluid within the first chamber and the second chamber increases.

10. A method associated with a high pressure valve comprising:

rotating a plug from an open position to a closed position, wherein in the open position the plug allows fracturing fluid to flow through tubing;

positioning a first assembly upstream from the plug, the first assembly including a first seat positioned upstream from the plug and configured to contact the plug;

moving the plug along a liner axis while in the closed position;

moving the first seat along the linear axis, the first assembly including a first chamber configured to generate a first piston force against the first seat;

positioning a second assembly downstream from the plug, the second assembly including a second seat positioned downstream from the plug and configured to contact the plug; and

moving the second seat along the linear axis based on movement on the first seat and based on receiving forces from the plug, the second assembly including a second chamber configured to generate a second piston force against the second seat;

moving fluid through a conduit to control the first force and the second force responsive to movement of the plug on the linear axis and the first seat or second seat receiving the forces from the plug, wherein the first force is inversely related to the second force, wherein the conduit directly communicating coupling the first chamber and the second chamber.

11. The method of claim 10 , wherein a first volume of fluid within the first chamber is dependent on a second volume of fluid within the second chamber, wherein the first volume and the second volume dynamically change.

12. The method of claim 10 ,

wherein the first force is dependent on the second force.

13. The method of claim 10 , further comprising:

configuring the conduit to extend across the plug.

14. The method of claim 13 , wherein the conduit provides a closed fluid path between the first chamber and the second chamber.

15. The method of claim 13 , further comprising:

positioning an external piston in fluid communication with the conduit, the external piston including a first side and a second side, the first side being configured to receive the fracturing fluid to move the external piston.

16. The method of claim 15 , further comprising:

moving the external piston to increase a total amount of hydraulic fluid within the first chamber and the second chamber.

17. The method of claim 10 , further comprising:

moving hydraulic fluid between the first chamber and the second chamber, wherein a total amount of the hydraulic fluid within the first chamber and the second chamber does not change.

18. The method of claim 17 , wherein responsive to moving a portion of the hydraulic fluid from the second chamber to the first chamber, the first force will increase and the second force will decrease.
