Abstract

Systems and methods include a method for downhole leak detection and prediction in water injection wells. Bulk well operation information for one or more wells is accessed from a database. Real-time pressure and water rate information is received from surface and downhole gauges during operation of a water injection well. Engineered prediction-ready data is generated using the real-time pressure and water rate information by translating the bulk well operation information. Early signs of leakage at sub-surfaces of the water injection well are determined using the engineered prediction-ready data and wellbore dynamics of the water injection well. Information associated the early signs of leakage is provided based on the determining and for presentation to one or more users.
