Partners in Ghana’s Tweneboa, Enyenra and Ntomme (TEN) oil fields have agreed on the final sale and purchase terms to acquire the floating production, storage and offloading (FPSO) vessel currently operating at the field, ahead of the expiry of its lease in 2027.

In its operational and financial update released on January 5, 2026, Kosmos Energy announced that a final Sale and Purchase Agreement is expected to be executed in early 2026. The agreement will see the TEN partnership transition from leasing the FPSO to outright ownership.

According to Kosmos Energy, the move is expected to deliver significant reductions in operating costs at the TEN field, with a positive impact on the company’s leverage position beginning in 2026.

“As ownership is transitioned to the partnership, we expect TEN operating costs to significantly reduce and positively impact the company’s leverage in 2026,” the company stated.

The decision comes as the TEN fields enter a more mature phase of production, making cost efficiency increasingly important to sustaining the asset’s long-term economic performance. Lower operating expenses are expected to enhance value and extend the viability of the fields over their remaining production life.

Although the purchase price of the FPSO was not disclosed, Kosmos confirmed that the acquisition aligns with its broader strategy to optimise its Ghana operations and strengthen cash flow.

The TEN fields remain one of Ghana’s three producing offshore oil developments and continue to play a central role in Kosmos Energy’s West African portfolio.
