As a result of reduction trend in exploration of new major oil fields and depletion of proven reserves categorized as easy oil, new challenges have arisen both from operational and reservoir standpoints to exploit more challenging hydrocarbon deposits due to the complexities in reservoir rock and fluid characteristics as well as flow assurance aspects. Therefore, surveillance data-driven analytics, measured and synthetic petrophysical properties, integrated with lithology and stress state properties become of interest to reduce uncertainties and risks involved in selecting reliable water shut off wells in complex carbonate reservoirs. As loss of well integrity during production due to poor cementing state is one of the most common reasons of problematic water production in wells, the coupled geomechanical modeling is performed in the selected candidates well will excess water issue based on diagnostics workflow. The results of simulation compared against cement logs confirms the depths of the well integrity issues, as a proactive step in oilfield produced water management.
