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 in 2020, 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 are also about to complete 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.
Phase 2A of the project completed
September: last well begins producing. Production goes beyond 30,000 barrels of oil equivalent per day.
April: first installation of our Inline Phase Splitter (IPS) technology.
Production at Litchendjili
Underwater pipework completed, meaning production at the Nené field can be sent to the onshore plant in Litchendjili.
First phase 2A well in production
The second platform in phase 2A is completed and the first well linked to the platform goes into production.
2A platform installed
The first platform in phase 2A is installed 12 months after approval. New wells are drilled and production is ramped up in the Nené field.
Production under way in Nené
Thanks to the undersea pipework, production has begun in the field. We rounded off recovery work in the well by tapping it safely.
For us, workplace safety is a fundamental principle that we share with employees, contract workers and local communities. That is why we implement all the necessary measures to avoid accidents, including organisational models to assess and manage risks, training programmes, skills development and the promotion of a culture of safety.
Undersea pipework 17 km long.
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.
Our results so far
A few highlights of our success:
3.5 billion boe
hydrocarbons discovered 2015-2017 in the block Marine XII
140,000 boe per day
production at the ceiling phase
length of the undersea pipework
increase in energy capacity at Congo power station in 2018
