In order to reduce the environmental impact of produced water management a wetland system is being installed in the Sultanate of Oman. The facility will reduce the disposal of hydrocarbon polluted produced water into deep aquifers, recover hydrocarbons by means of an additional oil/water separation step and decrease the overall power consumption of the oil field operation by using a gravity flow system. During construction measures have been taken to reduce the impact by using only local materials for the installation of a sealing layer.

The project is currently in the commissioning phase and first result have shown that up to 60 bbl/d of crude oil were recovered, an overall a reduction of the power consumption between 1.2 and 1.8 Mio MWh can possibly achieved in the 20 years of operation and due to the installation of a mineral sealing layer the impact during construction could be reduced by 80 % for this element compared to the installation of an artificial sealing.
