The purpose of the implemented project activity is to improve the energy efficiency of the Nimr produced water disposal system located in Oman by implementing an ecological wetland solution. Before the project implementation around 105,000 m³ per day (annually 38,152,635 m³) of oil contaminated water (herein after referred as “produced water”) is being transferred from the Nimr of the oil up-stream process of the Oil Concessionaire(Oman’s national oil producer majority owned by the Oman Ministry of Oil and Gas) to Nimr production station. From the Nimr Production station, the oil-contaminated water is injected to three (3) sites via energy intensive injection pumps into deep wells for final disposal. The Injection pumps consume about 5.56 kWh/m³ (annually 212,034 MWh per year) of fossil fuel-based grid electricity. This results into 134,609 tons of CO2 emitted into the atmosphere.

After the project (NWTP phase 3) implementation, which is designed to treat up to 80,000 m³/ day (annually 29,200,000 m³) of the produced water, which was disposed into deep-water disposal (DWD) wells. The mentioned amounts of produced water (80,000 m³/day) is disposed to a highly energy efficient ecological wetland close to the deep water well sites, which is consuming around 0.1 kWh/m³ of electricity only. The wetland facility is designed, built, operated, owned and transferred (DBOOT model) by Bauer Nimr LLC (project owner) next to an existing pilot wetland area.
