Instrumented packer
A technique that is usable with a subterranean well includes communicating a fluid into a region of the well and monitoring a level of the fluid communicated via a downhole sensor. The communication is controlled in response to the monitoring.
1. A method usable in a subterranean well, comprising:
forming an isolated zone inside a casing of the well;
inside the isolated zone, communicating a fluid into a region of the well, the region being located between the casing of the well and a wellbore of the well;
monitoring a level of the fluid communicated via a dowwnhole sensor; and
controlling the communication in response to the monitoring.
2. The method of claim 1 , further comprising introducing a tagging agent into the fluid.
3. The method of claim 2 , wherein the tagging agent comprises at least one of the following:
ferromagnetic particulates, salt and radioactive particulates.
4. The method of claim 1 , wherein the monitoring comprises detecting a tagging agent.
5. The method of claim 1 , wherein the monitoring comprises detecting the presence of at least one of the following:
ferromagnetic particulates, salt and radioactive particulates.
6. The method of claim 5 , wherein the downhole sensor comprises at least one of the following:
a gamma ray detector; a coil and a resistivity sensor.
7. The method of claim 1 , further comprising:
incorporating the sensor into a downhole tool.
8. The method of claim 1 , wherein the forming comprises:
setting at least one packer to establish the isolated zone.
9. The method of claim 7 , further comprising:
running the downhole tool into the well in association with the communicating.
10. The method of claim 8 , wherein said at least one packer includes two packers, one of the packers incorporates the sensor and the other of the packers incorporates another sensor.
11. The method of claim 1 , wherein the sensor indicates a level of the fluid.
12. The method of claim 1 , wherein the communicating the fluid comprises communicating at least one of the following:
cement and an acidizing fluid.
13. The method of claim 1 , wherein the communicating the fluid is part of a cement squeeze operation.
14. The method of claim 1 , wherein the communicating fluid is part of an acidizing operation.
15. A method usable in a subterranean well, comprising:
communicating a fluid into a region of the well, the region being located between a casing of the well and a wellbore of the well;
monitoring a level of the fluid communicated via a downhole sensor;
controlling the communication in response to the monitoring; and
incorporating the downhole sensor into a downhole tool, the downhole tool comprising a first packer that incorporates the downhole sensor and another packer that incorporates another sensor.
16. The method of claim 15 , further comprising introducing a tagging agent into the fluid.
17. The method of claim 15 , wherein the monitoring comprises detecting the presence of at least one of the following:
ferromagnetic particulates, salt and radioactive particulates.
18. The method of claim 17 , wherein the downhole sensor comprises at least one of the following:
a gamma ray detector, a coil and a resistivity sensor.
19. The method of claim 15 , wherein the communicating the fluid comprises communicating at least one of the following:
cement and an acidizing fluid.
20. A system usable with a subterranean well, comprising:
a casing string creating a region located outside of the casing string; and
a second string comprising a first packer comprising a first sensor to indicate a level of fluid in the region and a second packer comprising a second sensor,
wherein at least the first sensor is adapted to indicate presence of a tagging agent in the fluid.
21. The system of claim 20 , wherein the tagging agent comprises at least one of the following:
ferromagnetic particulates, salt and radioactive particulates.
22. The system of claim 20 , wherein the sensor comprises at least one of the following:
