West Nile Delta

Only about two years after the signing of extensive agreements, production started from one of the largest projects of the DEA company history - West Nile Delta in the Mediterranean Sea off the Egyptian coast. This is a very important milestone, not only for DEA and operator BP, but also for the country Egypt.

Production from two out of a total of five fields commenced in March 2017, Taurus and Libra. The other three fields of the project, Giza, Fayoum and Raven will go into production by 2019.

The West Nile Delta fields are located approximately 65 to 85 kilometres off the coast of Alexandria and were discovered during the exploration phase from 2000 to 2010. The gas and condensate fields are being developed in several phases. In the first phase of execution, five major fields are under development: Taurus, Libra, Giza, Fayoum and Raven. The additional discoveries Maadi, Viper, Ruby, Polaris and Hodoa are planned to be developed at a later stage. Production from the offshore WND gas fields commenced on 24 March 2017. Once gas is flowing from the five fields, DEA’s share of the output will add a volume of more than 250 million cubic feet of gas per day (about 40,000 barrel oil equivalents per day) to DEA’s production in Egypt.

Efficient use of existing infrastructure to accelerate field development

The WND project stepped into execution after the project partner DEA and operator BP signed the final agreements in March 2015. Two of the five fields under development, Taurus and Libra, have been fast-tracked and put in production.

The key to accelerate the first phase of the project was the efficient use of existing infrastructure. Efficient project management enabled the team to deliver below budget and ahead of the original start-up schedule.

The two fields Taurus and Libra are developed subsea, with a total of nine wells and an offshore tie-back of 42 kilometre length to existing offshore infrastructure. The Taurus and Libra offshore infrastructure has been installed in a water depth between 60 and 800 metres. Two subsea manifolds, a total of 79 kilometres of rigid pipelines, 68 kilometres of control umbilicals and 24 kilometres of flexible well flowlines have been installed on the seafloor. The offshore installation campaign started in July 2016 and achieved mechanical completion in February 2017.

The other three fields, Giza, Fayoum and Raven will be tied-back to the shore over long distance and deep-water. The existing Rosetta plant will be modified for Giza and Fayoum and integrated into a new adjacent onshore processing plant for Raven.

Geology characteristics

The Giza, Taurus, Libra, Fayoum, Maadi, Viper, Polaris and Ruby fields hold gas resources within the Pliocene formations, while the Raven field holds gas resources in the deeper Miocene formations. The Hodoa discovery holds gas resources within Oligocene formations.
