Abstract
Systems and methods include scale control in oilfield produced waters. Thermodynamic data indicative of surface conditions and subterranean conditions of a subterranean region including a well is received, from probes. An acidity of a produced water stream to be disposed in the well is received from a pH meter. A supersaturation degree of the produced water stream to be disposed in the well is determined, by using the thermodynamic data. An amount of carbon dioxide to be injected in the produced water stream to neutralize a scaling risk is determined, by the one or more processors, by using the supersaturation degree and the acidity. An injection of the amount of the carbon dioxide in the produced water stream is triggered to neutralize the scaling risk.
