Abstract
Introducing metal ions into fluids produced from a wellbore may inhibit the formation of scale on downhole production equipment. The ions may be introduced by one or more electrodes disposed in downhole locations such as in a sand control screen assembly, an inflow control device or in a production tubing base pipe. Parameters indicative or predictive of scale formation may be monitored, and an electrical voltage supplied to the electrodes may be adjusted to in response to any predetermined threshold of the parameters being exceeded. In some embodiments, a chemical ion source may be provided, which may release ions in response to erosion or corrosion reaction controlled by electrical power. Electric control of scale production allows for targeted feedback control of the amount of metal ions released as a scale inhibitor without requiring storage of downhole chemical solutions or the passage of fluid lines to downhole locations.
