We assess the impact of our operations on water resources through EIAs, which direct our conservation efforts and the development of innovative water management solutions. Water stewardship efforts Ensuring no process or industrial wastewater discharge to the desert Exploring the use of brine from desalination plants as an alternative for water injection Treating and recycling all sewage generated at ADNOC sites for the irrigation of green spaces Deploying mobile, self-contained units for the dewatering and reuse of drilling mud Reusing produced water for enhanced oil recovery, as well as for process and irrigation needs post treatment Mandating grey water treatment and re-using in accommodation design Adopting a no fresh surface and groundwater withdrawal for operations, drilling and well completion activities Employing a hypersaline23 groundwater closed-loop system to maintain reservoir pressure and enhanced well production Ensuring sustainable groundwater use that does not exceed natural aquifer recharge rates Implementing innovative solutions, fostering efficient water use and reduction at source Our commitment to sustainable water stewardship is guided by a comprehensive water conservation strategy, which drives the efficient and responsible use of water resources across our operations through: • Actively seeking opportunities to avoid unnecessary water use and applying reduce, reuse and recycle principles • Utilizing non-freshwater alternatives, including treated wastewater, wherever feasible • Deploying innovative technologies and water management solutions • Supporting safe water discharge 23 Hypersaline groundwater has total dissolved solids (TDS) above 150,000 ppm. 82
