Extracts crude from Ghana's Jubilee and TEN deepwater fields through FPSO-anchored subsea infrastructure where water depth makes fixed platforms physically impossible.
Tullow extracts crude from Ghana's Jubilee and TEN deepwater fields through FPSO vessels connected to subsea wellheads, because water depth makes fixed platforms physically impossible, which means every barrel produced must pass through a single infrastructure sequence before reaching Tema port via shuttle tanker. That sequence — subsea wells, FPSO storage, tanker scheduling, port logistics — creates a fixed throughput ceiling that can only be raised through entirely new capital deployment, and Ghana's Petroleum Commission governs how quickly the wells feeding that sequence can be drawn down, subordinating output to regulatory approval cycles rather than reservoir physics alone. The GNPC joint venture and accumulated subsea infrastructure together make operator substitution structurally difficult, but that same single-jurisdiction concentration means any regulatory revocation or forced license renegotiation eliminates the entire production mechanism with no other asset base to absorb the loss. Cedi devaluation raises local operating costs against dollar-denominated crude sales at the same time that IMO emissions rules require upgrades to the FPSO and shuttle tanker fleet, so external cost pressures compound against a system that cannot flex its throughput ceiling without triggering the capital deployments those pressures constrain.
How does this company make money?
Crude oil is sold per barrel at international benchmark prices, with transportation costs deducted. The split of proceeds between the company, the Ghanaian government, and joint venture partners is governed by production sharing contract terms and each partner's working interest percentage.
What makes this company hard to replace?
The Ghana National Petroleum Corporation joint venture agreements embed the company directly in Ghana's national oil development framework, making a straightforward operator substitution structurally difficult. The existing subsea infrastructure and accumulated reservoir knowledge together create technical barriers that would prevent an alternative operator from replicating production efficiency without rebuilding both from scratch.
What limits this company?
Ghana's Petroleum Commission approval cycles for reservoir management decisions create the governing throughput limit: production profiles from Jubilee and TEN cannot be optimized at the pace subsurface conditions permit because each material intervention requires regulatory authorization before execution.
What does this company depend on?
The operation depends on five named upstream inputs: the Ghana National Petroleum Corporation joint venture partnership, production permits issued by the Ghanaian Petroleum Commission, continued operation of the FPSO Kwame Nkrumah vessel, subsea wellhead maintenance contractors, and shuttle tanker offtake scheduling through Tema port.
Who depends on this company?
The Tema Oil Refinery loses its preferred crude feedstock supply if production stops. The Ghanaian government loses the petroleum income streams that fund national budget allocations. Kosmos Energy and other joint venture partners lose production volumes from their assets in these fields.
How does this company scale?
Subsea well drilling and completion techniques can be replicated across multiple reservoir targets within existing license areas. However, FPSO vessel capacity and the subsea infrastructure represent fixed throughput ceilings that can only be raised through entirely new capital deployments.
What external forces can significantly affect this company?
Devaluation of the Ghanaian cedi against the US dollar raises local operating costs while crude sales remain dollar-denominated, creating a cost-revenue currency mismatch. West African political conditions affect the flow of regional oil investment. International Maritime Organization emissions regulations require upgrades to the FPSO vessel and the shuttle tanker fleet.
Where is this company structurally vulnerable?
Because the differentiator is a single-jurisdiction infrastructure sequence tied to Ghanaian licenses and a GNPC partnership, any regulatory revocation, nationalization action, or forced license renegotiation in Ghana instantly eliminates the mechanism with no diversified production base to absorb the loss.
