Ghana has announced its first successful hydrocarbon discovery in a carbonate reservoir system, opening a new frontier for oil and gas exploration as the country seeks to replenish declining reserves and attract fresh investment into its petroleum industry.
President John Dramani Mahama announced the discovery on Nov. 10 at the opening of the 2026 Local Content Conference and Exhibition in Takoradi, in the country’s Western Region.
The discovery was made at the Nya Gyidie-1X exploration well in the Deepwater Cape Three Points (DWCTP) Block, approximately 148 kilometres offshore Ghana.
The well, operated by Planet One Oil & Gas in partnership with GOIL Upstream Limited and the Ghana National Petroleum Corporation (GNPC), was drilled in water depths of approximately 2,289 metres.
According to GNPC, hydrocarbons were encountered in carbonate rock formations between 3,364 and 3,499 metres measured depth along the wellbore.
The discovery marks Ghana’s first successful test of a Cenomanian-Turonian carbonate reservoir system as a primary exploration target. Previous commercial hydrocarbon discoveries in the country have largely been associated with sandstone formations.
Mahama described the development as an important milestone for Ghana’s petroleum industry, saying it demonstrated the potential for exploration beyond the geological formations traditionally targeted by operators.
The president said the discovery reflected growing confidence in Ghana’s petroleum prospects and the government’s efforts to revitalise the upstream sector.
However, the type and volume of hydrocarbons discovered have not yet been established. Further technical assessments are required to determine the size of the resource, its characteristics and whether it can be developed commercially.
GNPC Chief Executive Kwame Ntow Amoah said the significance of the discovery extended beyond the hydrocarbons encountered, as it had established a new geological play for future exploration.
He said the corporation would work with Planet One and GOIL Upstream to evaluate the discovery and determine the next steps towards possible development.
Planet One Chief Executive Andaleeb Sehgal also said further evaluation was underway to establish the scale of the discovery and the appropriate development approach.
The Deepwater Cape Three Points Block covers approximately 1,454 square kilometres and is operated by Planet One alongside its Ghanaian partners.
The discovery comes as Ghana intensifies efforts to reverse declining oil production, replace depleted reserves and attract investment into offshore exploration.
Mahama disclosed that the government had secured $3.5 billion in new upstream investment commitments in June 2026 as part of its efforts to strengthen the petroleum industry.
He also said partners in the Jubilee oil field had committed $2 billion to new projects involving additional wells, subsea infrastructure and production facility expansion.
The president further announced plans by GNPC, through its subsidiary Exploco, to begin drilling exploration wells in the Voltaian Basin in the first quarter of 2027.
Ghana’s latest discovery could broaden the country’s exploration prospects, although its contribution to future production and energy revenues will depend on the outcome of further technical and commercial assessments.
The government has said it wants petroleum investments to generate employment, strengthen local businesses, promote technology transfer and improve the country’s long-term energy security.
