  • Redundant systems for downhole permanent installations
    Patent number: 7520321
    Abstract: A well instrumentation system, comprising: a power and data supply; and a plurality of functional units attached to the power and data supply and distributed throughout the well, characterised in that the power and data supply comprises first and second substantially identical cables, and in that each unit comprises a first power supply channel and a first data channel connected to the first cable, a second power supply channel and a second data channel connected to the second cable, and a functional module which draws power from the first power supply channel or the second power channel module, and data from the first data channel or the second data channel. The power and data supply can comprise a surface unit that can be selectably connected to either the first or second cable. The selection of connection of the surface unit to one or other cable is effective to select the corresponding power and data channels in the functional units.
