Eni is investing four billion dollars in the development of the Baleine field offshore Côte d'Ivoire, marking one of the largest upstream commitments in West African energy in recent memory. The announcement confirms a full field development programme at Baleine, the discovery that Eni and its partner PETROCI brought to first oil with exceptional speed following the initial find. The scale of the capital commitment signals that Baleine is being treated as a major long-cycle asset rather than a fast-monetisation opportunity.
Baleine is a combined oil and gas field, and Eni has positioned it as a flagship low-carbon-intensity project for the company's African portfolio, with associated gas intended for domestic power generation in Côte d'Ivoire rather than flared or reinjected. The $4 billion envelope covers the full development scope needed to bring the field to plateau production, including subsea infrastructure, floating production capacity, and the gas export and utilisation systems tied to the country's power grid. PETROCI, the national oil company, holds a participating interest alongside Eni as operator.
Côte d'Ivoire's government has made Baleine a centrepiece of its energy sovereignty agenda, using the field's gas to reduce the country's dependence on imported power and expensive liquid fuel generation. The phased development model Eni is pursuing — Phase 1 already delivered first oil — means additional tranches of capital will flow into the country as each production phase is sanctioned and executed. The $4 billion figure appears to represent the full lifecycle investment across all planned phases rather than a single contract award.
For the West African offshore services market, a $4 billion operator commitment at an active field under phased development means a sustained, multi-year procurement cycle rather than a single construction campaign. Subsea tie-backs, additional wells, potential FPSO modifications or a second production vessel, pipeline infrastructure connecting to shore, and ongoing well intervention work all represent discrete scopes that will require competitive tendering as each phase is sanctioned. The combination of oil revenue and gas-to-power obligations gives Eni and PETROCI strong incentive to maintain development momentum.
