Abstract

Embodiments of the present disclosure include a remote well servicing system including a control unit and a remote servicing manifold. The control unit further includes a service fluid source and a control system. The remote servicing manifold further includes a fluid input line coupled to the service fluid source, a fluid output line couplable to a well component, and a valve coupled to the fluid input line and the fluid output line, wherein the valve, when actuated, places the fluid input line in fluid communication with the fluid output line and permits delivery of a service fluid from the service fluid source to the well component. The remote servicing manifold also includes a control line coupling the valve and the control system wherein the control system controls actuation of the valve via the control line.

First claim

The invention claimed is:

1. A remote well servicing system, comprising:
a fluid input line coupled to a service fluid source;
a plurality of fluid output lines respectively coupled to a plurality of well components;
a remote services manifold comprising:
a fluid input coupled to the fluid input line;
a plurality of fluid outputs coupled to the plurality of fluid output lines
a plurality of valves controlling greasing of the plurality of well components, the plurality of valves positioned within the remote servicing manifold and corresponding to the plurality of fluid outputs, wherein each of the plurality of valves, when actuated, places the fluid input line in fluid communication with a corresponding fluid output and permits a service fluid from the service fluid source to a corresponding well component, thereby greasing the corresponding well component; and
one or more control lines coupled to and controlling actuation of the plurality of valves.

2. The system of claim 1 , wherein the one or more control lines comprises a pneumatic control line.

3. The system of claim 1 , wherein the one or more control lines comprises a pneumatic control line and an electrical control line, and the one or more control lines controls actuation of the plurality of valves via a solenoid and a pneumatic actuator.

4. The system of claim 1 , where the remote servicing manifold further comprises a pressure booster that increases the pressure in the plurality of fluid output lines.

5. The system of claim 1 , wherein the remote servicing manifold is coupled to a bleed line, wherein service fluid in the remote service manifold, the fluid input line, and/or the plurality of fluid output lines, is selectively directed into the bleed line to relieve pressure.

6. The system of claim 2 , wherein the pneumatic control line is selectively coupled to a pneumatic bleed line to relieve pressure.

7. The system of claim 1 , wherein the service fluid comprises a grease or a lubricant.

8. The system of claim 1 , further comprising a controller that controls the plurality of valves via the one or more control lines, and wherein the controller is remotely or wirelessly located from the remote servicing manifold.

9. The system of claim 1 , further comprising a controller that automatically controls the plurality of valves via the one or more control lines based on a predetermined condition.

10. A remote well servicing system, comprising:
a control unit, comprising:
a service fluid source; and
a control system;

a remote servicing manifold, comprising:
a fluid input coupled to the service fluid source via a fluid input line;
a plurality of fluid outputs couplable to a plurality of well components via a plurality of fluid output lines;
a plurality of valves controlling greasing of the plurality of well components, the plurality of valves positioned within the remote servicing manifold and corresponding to the plurality of fluid outputs, wherein each of the plurality of valves, when actuated, places the fluid input line in fluid communication with a corresponding fluid output and permits delivery of a service fluid from the service fluid source to a corresponding well component, thereby greasing the corresponding well component; and
one or more control lines coupling the plurality of valves and the control system, wherein the control system controls actuation of the plurality of valves via the one or more control lines.

11. The system of claim 10 , further comprising a plurality of the remote service manifolds, each of which comprises a fluid input line coupled to the service fluid source at the control unit.

12. The system of claim 10 , wherein the control system comprises a user interface.

13. The system of claim 10 , wherein the control system controls actuation of the plurality of valves based on a command received from a user device.

14. A method of remotely servicing a plurality of well components, comprising:
supplying a service fluid to a remote servicing manifold via a fluid input line coupled to a fluid source;
remotely actuating a valve of a plurality of valves within the remote servicing manifold via a control line coupled to the valve, thereby permitting flow of the service fluid;
delivering the service fluid from the remote servicing manifold to a well component via a fluid output line; and
greasing the well component with the service fluid.

15. The method of claim 14 , further comprising delivering the service fluid from the remote servicing manifold to a plurality of well components simultaneously.

16. The method of claim 14 , wherein the service fluid is a greasing fluid or a lubricant.

17. The method of claim 14 , further comprising actuating the valve electrically, pneumatically, or electro-pneumatically.

18. The method of claim 14 , further comprising relieving pressure in the remote servicing manifold by permitting flow of the service fluid into a bleed line.
