The Ghana National Petroleum Corporation (GNPC) has announced that it will commence drilling its first exploration well in the Voltaian Basin in 2025.
The announcement was made by Michael Aryeetey, GNPC’s Manager for Exploration and Appraisal, during the 2024 Local Content Conference and Exhibition (LCCE) in Takoradi. This marks a significant shift in Ghana’s energy exploration strategy, as the focus expands from the country’s traditional offshore oil fields to its vast onshore potential.
“For years, the focus has been on offshore exploration, particularly in areas like the Tano Basin, which has yielded significant discoveries,” Mr. Aryeetey said during his presentation. “But now, we are shifting our gaze inland, to the Voltaian Basin, which could be Ghana’s next big thing in oil and gas exploration.”
Mr. Aryeetey highlighted the importance of the Voltaian Basin, describing it as a potential “game changer” for Ghana’s energy sector. He emphasized that the basin, which spans over 100,000 square kilometers, holds immense geological promise.
While it remains largely unexplored, the area has the potential to unlock significant oil and gas reserves, which could dramatically transform the country’s energy landscape.
The Voltaian Basin, located in the eastern and central parts of Ghana, is a vast, underexplored onshore area that surpasses the size of the country’s offshore blocks. Offshore areas, such as the Tano Basin, which have been the focal points of Ghana’s oil production, cover less than 70,000 square kilometers in total.
The basin’s potential has long been recognized, but it has remained largely untapped for decades. Initial exploration efforts in the area date back to the 1960s when the Ghanaian government partnered with the former USSR to conduct preliminary geological surveys.
However, interest in the Voltaian Basin waned until 2005, when a resurgence of activity began with the support of the European Union and the Minerals Commission.
Since then, GNPC has invested heavily in the exploration of the basin, committing over $160 million to seismic data acquisition. These efforts have provided crucial insights into the geological structures of the Voltaian Basin and confirmed the presence of essential elements for a working petroleum system.
According to Mr. Aryeetey, this includes organic-rich shales and significant sedimentary thickness, both of which are promising indicators for the presence of oil and gas reserves.
Strategic Shift Toward Onshore Exploration
The decision to prioritize the Voltaian Basin represents a strategic shift for Ghana, which has traditionally focused on offshore oil production. Offshore fields such as the Jubilee and TEN fields, located in the Tano Basin, have been instrumental in establishing Ghana as a key player in the oil industry.
“Offshore blocks have yielded considerable success, but onshore exploration is the next frontier for Ghana’s oil and gas industry.
“The Voltaian Basin offers an opportunity for large-scale exploration that could redefine the energy landscape for our country.”

GNPC’s plan to drill the first exploration well by 2025 signals a significant step toward unlocking the potential of this onshore basin. The corporation has taken the lead in the exploration phase to ensure thorough analysis of the basin before opening it up to international investors.
“Our next steps involve securing relevant approvals, attracting joint venture partners, and preparing for the drilling of the first well,” Mr. Aryeetey explained. “By 2025, we hope to have made significant progress toward this goal.”
The potential discovery of oil and gas in the Voltaian Basin could have far-reaching economic implications for Ghana. Mr. Aryeetey emphasized that a successful onshore discovery would not only diversify the country’s energy sources but also enhance energy security, reducing reliance on imported energy.
“A major discovery would attract significant foreign direct investment, boosting the local economy and creating jobs.
“It could also result in a significant increase in government revenue, providing resources for national development.”

The basin, which has remained underexplored for decades, could become the next big thing in the country’s oil and gas sector. With the potential to diversify Ghana’s energy sources, reduce its reliance on imports, and attract significant foreign investment, the Voltaian Basin could be a game-changer for the nation.
The success of this exploration could herald a new chapter for Ghana, positioning the country as a leader in both offshore and onshore energy production in the West African region.
