Ghana’s Cybele Energy has inked a Production Sharing Agreement for a shallow water offshore acreage in Guyana.
In the week of December 8, 2025, the Accra-headquartered company, headed by president Beatrice Mensah‑Tayui signed a $17Milion- deal for Block S7, awarded under the country’s first competitive licensing round, which was announced in February 2025.
Block S7 is located outside disputed territorial zones and benefits from 3D-seismic data overlapping the Carapa‑1 area.
Cybele Energy was the second of the three groups awarded four blocks to sig its PSA with the Guyanese authorities. In November 2025, TOTALEnergies (leading its partners Qatar Energy and Petronas), signed a $15Million agreement for shallow-water Block S4, in what was described as a new deal under Guyana’s updated oil framework.
The 100% Guyanese-owned International Group Investment Inc. (IGI), which was awarded two blocks S5 & S10, has not concluded its negotiations.
Production figures published by Cybele Energy are a stretch. The statement says the plan is to produce up to 160,000Barrels of Oil Per day from a development concept using eight production wells and onshore early production facilities. This kind of output would suggest that a large discovery of at least 600Million barrels of oil is proven and that flow assurance dynamics have been determined to support it. AOGR believes that this statement is highly speculative. You can’t be talking about <100KBPD output in the same statement in which you are reporting the signature of a PSA agreement for a new block that you haven’t taken charge of.
The country’s PSA structure includes a 65% cost‑recovery clause for shallow‑water blocks. In Cybele’s view, this “enhances the block’s commercial viability”.
The block lies 50 kilometres from ExxonMobil’s Liza projects and is estimated to hold 400Million barrels of recoverable oil, Cybele claims. Drilling of the first exploration well is due within 12 months of the PSA’s effective date.
Cybele Energy’s technical partners include Norway‑based Well Expertise, which describes itself as providing “a one-stop shop for projects related to exploration, appraisal, development, PP&A, CCS, including consultancy services”. Well Expertise is represented on Cybele Energy’s Executve Management by Wim Kouwe, designated as Block S7 Geoscience Advisor, Well Expertise. Kouwe has worked as Chief Geologist for (the defunct German operator) Wintershall in Libya; he was asset and exploration manager for Cairn Energy for 11years, according to his LinkedIn. Cybele Energy’s Vice President for Geology & Geophysics is Segun Jebutu, who was, until March 2022, Regional Manager for Baker Hughes in the Gulf of Mexico, United States.
All of these indicate technical manpower, but Cybele has to raise the finance for operations.
The PSA on S7 was signed in Georgetown at a government‑hosted ceremony, supported by legal advisor Africa Legal Associates (ALA), local media reported. ALA advised Cybele Energy through a three‑year licensing and negotiation process.
