Nené Marine: offshore hydrocarbons in the Republic of Congo

We began production of the field in 2015. The gas from the field powers the CEC plant, which supplies electricity to the country.

Production begins 16 months after discovery

Nené Marine, in the block Marine XII, of which we are a producer with 65%, produces hydrocarbons from the pre-salt formation Djeno, 28 m under water, near existing plants. We began producing in the offshore field in 2014, eight months after getting the production permit and 16 months after discovering it through exploration. The complete development of the field is through various phases and involves installing a production and drilling platform with over 20 wells, with a ceiling of 50,000 barrels of oil equivalent a day. In 2019, phase 2A operations for the Nené Marine project began, with 12 new wells linked to two platforms going into production, making a total of 15 wells. The year also saw phase 2B for Nené approved. We also began building a new platform, which will be installed, alongside new undersea pipework. Drilling of the first well in phase 2B has already begun, in preparation for the early production launch, and we are making the most of synergies with existing facilities. We also completed installation of the third turbine, which will increase electrical generation capacity at Congo power station (20% of which is owned by Eni) by 170 MW. The extra gas will be produced in the block.

In 2019, we completed phase 2A of the Nené Marine project by putting a total of 15 wells into production and approved the implementation of phase 2B during the year.

Safety first

Safety in the workplace is an imperative value we want to share with our employees, contractors and local stakeholders. We are committed to eliminate accidents and protect the integrity of our assets. We consolidate a culture of safety through management and organization models, digital tools and communication initiatives. Our goal is strengthening the awareness of our people and their sense of responsibility toward themselves and others, by expanding HSE tools and digitalization to make corporate processes safer, more efficient and faster.

Impact on the environment and communities

We have never done exploration or development work for hydrocarbons within the boundaries of natural sites on the UNESCO World Heritage list, and in May 2019, we formally committed never to do so, officially instating a biodiversity and ecosystem services (BES) policy that we had already followed in our operations and which is part of our path of transformation. We are committed to long-term investment, going beyond profit priorities in the short term from the operating and social point of view, as recognised in our new company mission, which is inspired by the UN's Sustainable Development Goals.
