Kosmos energy updates on the grand tortue ahmeyim gas project progress

The highly anticipated Grand Tortue Ahmeyim (GTA) gas project, jointly managed by American firm Kosmos Energy and spanning the maritime border between Senegal and Mauritania, has once again captured attention. The Texas-based energy company recently provided fresh insights into the production ramp-up of this significant cross-border field. Phase one of the project officially commenced commercial production in early 2025. This initiative is under close scrutiny in Dakar, where Prime Minister Ousmane Sonko has emphasized control over extractive resources as a defining political objective of his administration.

A pivotal cross-border project for Dakar and Nouakchott

Following extensive negotiations between the two capitals, the GTA project is strategically positioned on a gas field located precisely at the maritime boundary separating Senegal and Mauritania. A rare arrangement in the West African extractive industry, the project features an equitable, 50/50 split of resources between the two nations. Kosmos Energy leads the development efforts alongside bp, the long-standing operator of the concession. Meanwhile, national companies Petrosen for Senegal and the Société Mauritanienne des Hydrocarbures (SMH) for Mauritania represent their respective states’ participation.

The initial phase of the project relies on a Floating Liquefied Natural Gas (FLNG) unit, designed to process gas for export to global markets. The targeted initial capacity is approximately 2.3 million tonnes of LNG annually. Kosmos has confirmed that production is steadily advancing towards its nominal plateau, following the successful completion of technical commissioning last year and the subsequent dispatch of the first gas cargoes.

Kosmos energy navigates senegalese political expectations

Since the Bassirou Diomaye Faye – Ousmane Sonko administration took office in March 2024, the trajectory of the GTA project has been subject to intense monitoring in Dakar. The Senegalese head of government has repeatedly articulated his intent to renegotiate or audit contracts inherited from the previous regime, which were often deemed imbalanced and disadvantageous to the state. This assertive stance introduced a period of uncertainty for international operators, with Kosmos and bp at the forefront.

The recent communication from the American group aims specifically to provide reassurance regarding the operational timeline. Kosmos underscores the stability of its partnership with authorities in both countries and confirms ongoing technical discussions concerning subsequent project phases. Nevertheless, the company has adjusted some of its ambitions downwards, as several financial analysts observed a disparity between initial targets and the actual volumes produced during the early months of operation.

Crucially, the successful ramp-up of the GTA field is expected to generate substantial budgetary revenues for both Senegal and Mauritania. On the Senegalese side, projections indicate several hundred billion CFA francs in annual income once full capacity is achieved. These funds are earmarked for the Fonds Intergénérationnel and the national budget, two essential mechanisms within Dakar’s natural resource management framework.

Phase 2, local content, and energy sovereignty

Beyond the initial phase, attention is now shifting towards the project’s expansion. GTA Phase 2, long discussed as a means to boost capacity to approximately 3 million tonnes per year, remains contingent on an agreement among industrial partners and governments. Kosmos has indicated that studies are progressing, though without a firm calendar commitment at this stage. The prevailing international LNG prices and the operator’s stated debt reduction strategy also factor into the equation.

For both Dakar and Nouakchott, the issue of local content remains a sensitive point. The Senegalese government has expressed its strong desire to see more national enterprises integrated across the value chain, from industrial subcontracting to logistics services. Ousmane Sonko has also raised the possibility of directing a portion of the gas production towards domestic supply, particularly to fuel thermal power plants and alleviate the nation’s energy costs, bolstering energy sovereignty in West Africa.

However, the authorities’ room for maneuver is constrained by existing contracts and the imperative to maintain the attractiveness of the MSGBC sedimentary basin. Several adjacent blocks are still undergoing exploration, and the approach adopted towards Kosmos and bp will serve as a crucial signal to potential investors. The credibility of Senegal’s gas ambitions is being determined not only within the FLNG unit’s engine rooms but also in the ministerial offices of Dakar, shaping the future of the political Sahel.
