The Nasr (Al-Nasr) oil field is situated approximately 130km northwest of Abu Dhabi, UAE. Initial oil production began in January 2015, marking the completion of Phase I (early development phase).
The field is operated by Adma-Opco, a joint venture comprising Abu Dhabi National Oil Company (Adnoc – 60%), BP (14.67%), Total (13.33%), and Japan Oil Development Company (Jodco, a subsidiary of Inpex – 12%).

Phase II of the Nasr Full Field Development Project aimed to increase oil production capacity from 22,000 barrels per day (bpd) to 65,000 bpd and concluded in the first half of 2019.
This project forms part of Adma-Opco’s overall strategy to fast-track the development of new fields, including Satah Al Razboot (SARB) and Umm Lulu, contributing to an additional production capacity increase of 270,000 bpd.
Nasr Phase I development details
Nasr Phase I was jointly developed with the Umm Lulu Phase I project, which started production in October 2014. The combined development of these two fields involved approximately 6,000 tons of structural steel, 28,000m of piping, more than 4,300 valves, 35,000 flanges and pipe fittings, and around 200km of cables.
Phase I comprised the installation of two wellhead towers (WHT 1&2) and a manifold tower (MFT-1), which connected to neighbouring facilities at Abu Al Bukoosh (ABK) and Umm Shaif.
Oil from Nasr is transported to these adjacent facilities, facilitating seamless operations.
Nasr Phase II Full Field Development Project
The Nasr Phase II Full Field Development Project was divided into three EPC packages. Package 1 involved constructing seven wellhead towers and installing 110km of infield pipelines, a 32km excess gas pipeline, and a 70km oil export pipeline.
Package 2 formed the core infrastructure, consisting of a multi-platform super complex incorporating a gas treatment platform, separation and accommodation platforms, utilities, flares, and connecting bridges.
Package 2 also included the installation of 44km of subsea power and 55km of subsea cables.
Package 3 provided project management consultancy (PMC) services, awarded to Technip with a contract value of approximately $206 million.
