Ghana Makes First Carbonate Oil Discovery Offshore

Ghana has announced its first hydrocarbon discovery in a carbonate reservoir, a geological breakthrough that could revitalize the country’s maturing upstream sector. The find at the Nya Gyidie-1X well, located 148 kilometers (92 miles) offshore in the Deepwater Cape Three Points block, marks a strategic departure from the sandstone formations that have historically yielded Ghana’s commercial oil and gas.

Operated by Planet One Oil & Gas alongside GOIL Upstream and the Ghana National Petroleum Corporation, the deepwater well encountered hydrocarbons at a depth of 2,289 meters (7,510 feet). Commercial viability, however, remains unproven. Planet One anticipates 12 to 18 months of further evaluation to determine the discovery’s scale, composition, and optimal development strategy.

The milestone supports President John Dramani Mahama’s broader campaign to reverse declining reserves and attract foreign capital. Underscoring this ambition, Ghana recently advanced a US$28 billion expansion of its Petroleum Hub, anchored by a proposed 300,000-barrel-per-day refinery. Coupled with US$3.5 billion in recent upstream investment commitments, the strategy signals Ghana’s intent to cement its position as West Africa’s premier fuel-processing and distribution hub.
