Abstract: A system and method for preventing scale in a well. The system includes a conduit providing fluid communication between a first location and a second location and a sensor at the second location configured to measure scale deposition in the fluid and a value of a fluid parameter. A scale deposition at the first location is determined from the scale deposition at the second location and the fluid parameter at the second location. A scale inhibitor is injected at the first location based on the determined scale deposition at the first location.

Abstract: A scale sensor comprises sensor electrodes including an uncoated porous metal working electrode and a counter electrode; and an impedance analyzer electrically coupled to the sensor electrodes. A method of monitoring scale deposition comprises placing an uncoated porous metal working electrode and a counter electrode in a fluid to be monitored; and monitoring scale deposition on the uncoated porous metal working electrode using an impedance analyzer electrically coupled to the uncoated porous metal working electrode and the counter electrode.
