Abstract (en)
[origin: WO2015185859A1] The system for operating and monitoring a well for extracting or storing a fluid to be used, such as natural gas, comprises a tubing (20) in which the fluid to be used flows, a protective casing (60) disposed around the tubing (20) and a cement sheath (30) interposed between the casing (60) and a rock formation (70) through which the well extends. The system further comprises, outside the casing (60), between same and the cement sheath (30), a series of electronic units (110) distributed in predefined positions in a succession of planes perpendicular to the casing (60) and spaced apart axially along the casing (60). Each electronic unit (110) comprises a communication means (14) for the electronic unit to communicate with another electronic unit (110) or a surface terminal (100), a power supply unit (13) of the electronic unit (110) and at least one of the following elements: a) a detection unit comprising at least one sensor (11) for sensing a physical or chemical quantity and b) a signal processing unit (12).
