The process of mineral scale precipitation and deposition is a common problem in oil fields. It is usually attributed to the mixing of incompatible water during secondary recovery stages. This issue can also be caused by thermodynamic and operating conditions during primary production stages. There are several methods proposed to predict mineral scale precipitation and deposition. Some of these methods are disruptive, based on artificial intelligence and machine learning, which rely on large amounts of historical information about past precipitation and deposition events. Therefore, expertise in identifying and differentiating scales, as well as access to reliable data, are important factors in the predictive success of these empirical models. To address this problem, there is a need to develop novel or integrative methodologies for diagnosing the CaCO3 scale deposition. These methodologies should be supported by primary water tests and production data available in oil fields. In this paper, we present the results of a new integrated method that estimates formation damage due to CaCO3 scale precipitation in producing wells using day-to-day field data, such as historical production, reservoir properties, and physicochemical characteristics of the formation water. The methodologies also include an operational risk management diagram. The method was successfully tested in four wells of the USCO field, located in Colombia. The results showed that three of the wells had the potential for CaCO3 deposition due to unfavorable operational conditions for the thermodynamic stability of the minerals dissolution into the formation water. Additionally, the fourth well remained undamaged because its high bottom pressure and low production water rate hindered the formation of CaCO3 scale. The methodology for evaluating the saturation index was compared with the results obtained by PHREEQC software. One advantage of our methodology is that it can effectively predict and manage scale occurrence, leading to increased productivity in oil-producing wells.
