Abstract

A telemetry system including a tubular. A pump in operable communication with the tubular configured to pump a fluid through the tubular; a flow altering arrangement in operable communication with at least one of the pump and the tubular. A flow interacting detail disposed in the tubular; and a load sensor configured to detect forces imposed on the flow interacting detail due to flow through the flow interacting detail and output signals related to the forces detected. Also included is a method of communicating through a tubular.

First claim

What is claimed is:

1. A telemetry system comprising:
a tubular having a wall defining an inner annular surface;
a pump in operable communication with the tubular configured to pump a fluid through the tubular;
a flow altering arrangement in operable communication with at least one of the pump and the tubular;
a flow interacting detail mounted to the wall extending about the inner annular surface of the tubular; and
a load sensor configured to measure forces imposed on the flow interacting detail due to flow through the flow interacting detail and output signals related to the forces measured.

2. The telemetry system of claim 1 , wherein the output signals are proportional to the forces measured.

3. The telemetry system of claim 1 , further comprising a processor in operable communication with the load sensor configured to track the output signals over time.

4. The telemetry system of claim 3 , wherein the telemetry system is configured to transmit data at least from the pump to the processor through changes in flow.

5. The telemetry system of claim 1 , wherein the smallest radial dimensions of the flow interacting detail are no smaller than the smallest radial dimensions of the tubular.

6. The telemetry system of claim 1 , wherein the flow interacting detail includes at least one recess on an inner radial surface thereof.

7. The telemetry system of claim 1 , wherein the flow interacting detail allows passage of tools therethrough.

8. The telemetry system of claim 1 , wherein the flow interacting detail includes an orifice.

9. The telemetry system of claim 1 , wherein the tubular is one of a liner, a casing, and a drill string disposed in an earth formation borehole.

10. The telemetry system of claim 1 , wherein the flow interacting detail and the load sensor remain downhole as part of a completion.

11. The telemetry system of claim 1 , wherein the load sensor includes one or more of a strain gauge, a piezoelectric sensor, a capacitive sensor, or combinations of one or more of the foregoing.

12. The telemetry system of claim 1 , wherein the flow interacting detail is substantially immovable in relation to the tubular.

13. The telemetry system of claim 1 , wherein the flow altering arrangement is the pump.

14. The telemetry system of claim 1 , wherein the flow altering includes altering rates of flow.

15. The telemetry system of claim 1 , wherein the flow interacting detail extends entirely about the inner annular surface.

16. A method of communicating through a tubular, comprising:
flowing fluid through a tubular including a wall defining an inner annular surface and having a flow interacting detail mounted to the wall extending about the inner annular surface;
altering flow of the fluid through the flow interacting detail;
measuring force on the flow interacting detail related to the flow of the fluid; and
tracking the measured force over time.

17. The method of communicating through a tubular of claim 16 , further comprising transmitting data from an arrangement altering the flow to a sensor measuring the force.

18. The method of communicating through a tubular of claim 17 , wherein the transmitting data is through continuous phase modulation.

19. The method of communicating through a tubular of claim 16 , further comprising avoiding restricting intervention through the tubular and the flow interacting detail by not reducing inner radial dimensions of the flow interacting detail to dimensions smaller than minimum radial dimensions of the tubular.

20. The method of communicating through a tubular of claim 16 , further comprising maintaining the relative position between the flow interacting detail and the tubular.

21. The method of communicating through a tubular of claim 16 , wherein altering flow includes altering rates of flow.
