A joint strategic initiative between ADNOC and Abu Dhabi National Energy Company (TAQA), Project Wave reflects ADNOC’s commitment to sustainable water management. The project is designed to reduce or eliminate the use of non-renewable groundwater by utilizing seawater as an alternative source through the development of an independent treatment facility using advanced nanofiltration technology. The industry-leading facility is expected to receive up to 100% of its power from the clean energy grid and treat 115 million imperial gallons per day (MIGD) of nano filtered seawater, reducing water injection related energy consumption by up to 30%. The construction of a nanofiltration plant, water transportation system and pumping stations to supply treated seawater for enhanced oil recovery at Bab and Bu Hasa fields are currently underway and are expected to start operations in 2026. By providing a dedicated supply of low salinity treated seawater, Project Wave will ensure a sustainable and long- term water source for ADNOC’s onshore operations, preserving natural aquifers and supporting responsible resource use. The project contributes to ADNOC’s water stewardship by safeguarding aquifer recharge capacity, improving water injection performance and reducing both CAPEX and OPEX. It represents a long-term commitment to minimizing environmental impact while enabling operational resilience across our upstream assets. Project wave – sustainable water management “ Project Wave shows the impact that innovative water management can have at scale. We’re delivering a seawater nanofiltration plant that should supply 115 million imperial gallons of treated water per day to support reservoir pressure in the Bab and Bu Hasa fields. By replacing deep aquifer saline water systems, we’re reducing water-injection related energy use by up to 30% and using clean energy sources to power the process. It’s a more efficient and responsible way to manage water in our operations.” ● Omar Hasan Al Marzooqi General Manager, ADNOC Upstream PROTECTING NATURE AND BIODIVERSITY ADVANCING NET ZERO KEEPING OUR PEOPLE SAFE EMPOWERING LIVES HOW WE OPERATE SUSTAINABILITY AT ADNOC ABOUT ADNOC 83 ADNOC Sustainability Report 2024
