Intelligent well system and method
View Patent ↗An intelligent well system and method has a sand face completion and a monitoring system to monitor application of a well operation. Various equipment and services may be used. In another aspect, the invention provides a monitoring system for determining placement of a well treatment. Yet another aspect of the invention is an instrumented sand screen. Another aspect is a connector for routing control lines.
1. A method for monitoring an operation in a well, comprising:
injecting a cement into the well;
monitoring a characteristic in the well by using a sensor positioned in the well, the sensor being a fiber optic line; and
determining a placement position of the cement in the well from the monitored characteristic, wherein the fiber optic line provides a distributed temperature measurement.
2. The method of claim 1 , further comprising injecting gravel slurry or additional cement into the well in response into the determined placement position of the cement in the well.
3. The method of claim 1 , wherein the sensor is positioned proximate a screen.
4. A method for monitoring an operation in a well, comprising:
injecting a cement into the well;
monitoring a characteristic in the well by using a sensor positioned in the well, the sensor being a fiber optic line; and
determining a placement position of the cement in the well from the monitored characteristic, wherein the fiber optic line provides a distributed stress measurement.
5. The method of claim 4 , further comprising injecting gravel slurry or additional cement into the well in response into the determined placement position of the cement in the well.
6. The method of claim 4 , wherein the sensor is positioned proximate a screen.
7. A method for monitoring an operation in a well, comprising:
injecting a cement into the well;
monitoring a characteristic in the well by using a sensor positioned in the well, the sensor being a fiber optic line; and
determining a placement position of the cement in the well from the monitored characteristic, wherein the fiber optic line provides a distributed strain measurement.
8. The method of claim 7 , further comprising injecting gravel slurry or additional cement into the well in response into the determined placement position of the cement in the well.
9. The method of claim 7 , wherein the sensor is positioned proximate a screen.
10. A method for monitoring an operation in a well, comprising:
injecting a cement into the well;
monitoring a characteristic in the well by using a sensor positioned in the well, the sensor being a fiber optic line; and
determining a placement position of the cement in the well from the monitored characteristic, wherein the fiber optic line provides a distributed sand detection measurement.
11. The method of claim 10 , further comprising injecting gravel slurry or additional cement into the well in response into the determined placement position of the cement in the well.
12. The method of claim 10 , wherein the sensor is positioned proximate a screen.
13. A method for monitoring an operation in a well, comprising:
injecting a cement into the well;
monitoring a characteristic in the well by using a sensor positioned in the well, the sensor being a fiber optic line; and
determining a placement position of the cement in the well from the monitored characteristic, wherein the fiber optic line provides a distributed seismic measurement.
14. The method of claim 13 , further comprising injecting gravel slurry or additional cement into the well in response into the determined placement position of the cement in the well.
15. The method of claim 13 , wherein the sensor is positioned proximate a screen.
16. A method for monitoring an operation in a well, comprising:
injecting a cement into the well;
monitoring a characteristic in the well by using a sensor positioned in the well, the sensor being a fiber optic line;
determining a placement position of the cement in the well from the monitored characteristic, wherein the fiber optic line provides a distributed measurement; and
performing a remedial action based upon the determined placement.
17. The method of claim 16 , wherein the distributed measurement provided by the fiber optic line is a distributed pressure measurement.
18. The method of claim 16 , wherein the monitored characteristic is selected from temperature, pressure, flow, stress, strain, sand detection, and seismic measurements.
19. The method of claim 16 , wherein the remedial action is selected from the group consisting of injecting gravel slurry or additional cement into the well, actuating a sleeve, and actuating a valve.
20. The method of claim 16 , wherein the sensor is positioned proximate a screen.
