Evaluating Sugarcane Irrigation Water for Sustainable Enhanced Oil Recovery and Efficient Waste Management

As global water scarcity intensifies, industries like oil and gas are increasingly exploring alternative water sources to meet operational needs. This study evaluates the potential of using sugarcane irrigation water as an environmentally sustainable solution in petroleum engineering, specifically for enhanced oil recovery (EOR). The research investigates the compatibility of two distinct sugarcane irrigation water samples with five crude oil types, examining key parameters such as emulsion formation, organic matter deposition, interfacial tension (IFT), and wettability alteration. The results reveal significant variability in phase separation, ranging from 37–82% over a three-hour period. A notable correlation is found between lower IFT values and enhanced emulsion stability. Moreover, the sugarcane irrigation water samples reduce the contact angle by up to 36˚, suggesting their potential to alter the wettability of reservoir rocks from oil-wet to neutral-wet conditions. This indicates that sugarcane irrigation water can be used as a sustainable alternative in EOR, minimizing the need for freshwater resources while reducing environmental pressures associated with water consumption and wastewater disposal in the oil and gas sector. The study advocates for the adoption of water reuse strategies, promoting environmentally sound practices that conserve water resources and reduce the ecological footprint of petroleum operations.
