The Ghasha and Hail fields are located within the Marawah Marine Biosphere Reserve, west of Abu Dhabi Island. It was the first biosphere reserve in the UAE that was recognized by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 2007.
The reserve is rich in coastal ecosystems such as coral reefs, seagrass beds, and mangroves. It is also home to the world’s second-largest population of dugongs, an endangered marine species that feed on seagrass and prefer to live in shallow waters.
In line with ADNOC’s ongoing commitment to protecting the biodiverse marine environment, the company worked in close partnership with the Environment Agency - Abu Dhabi (EAD) and conducted one of the largest marine Environmental Impact Assessment (EIA) studies ever undertaken in the UAE. Collectively, they integrated the findings into a robust biodiversity monitoring program that detailed how they would minimize our potential environmental footprint throughout the lifetime of the project. The program includes monitoring elements such as marine mammal and reptile observation, bird surveys, quality of marine water (both in-situ and analytical), in-fauna sediment testing, underwater noise levels, and reclamation fill.
The use of artificial islands will provide habitats to marine life by eliminating the need to dredge over 100 locations for wells. Through onshore and offshore clustering technologies, the environmental footprint of the project was minimized as they enabled the drilling of several wells from a common location.
In relation to our wider marine environment, 2.3 million mangrove seedlings have been planted across ADNOC’s nurseries in Al Dabbia and Zirku Island, and 550,000 across Abu Dhabi. 293 artificial coral reef structures have also been deployed in Makasib Island, Rock Mosfayer, Zirku Island, Nitah, and Das Island.
