Abstract
Downhole electrical energy harvesting and communication in systems for well installations having metallic structure carrying electric current, for example CP current. In some instances there is a harvesting module () electrically connected to the metallic structure () at a first location and to a second location spaced from the first location, the first and second locations being chosen such that, in use, there is a potential difference therebetween due to the electric current flowing in the structure (); and the harvesting module () being arranged to harvest electrical energy from the electric current. In addition or alternatively, there may be communication apparatus () for communication by modulation of the current, for example CP current, in the metallic structure ().
