Abstract
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.
Claims22
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.
