Springfield Exploration and Production (SEP) Limited, in collaboration with the Ghana National Petroleum Corporation (GNPC) and GNPC EXPLORCO, has successfully completed an appraisal well test for the Afina discovery, marking a significant milestone in Ghana’s energy sector.
Highlights of the Afina-1x Well Test
- The appraisal test, conducted through a re-entry of the Afina-1x well, confirmed promising hydrocarbon potential.
- The Cenomanian sandstone flowed at a maximum rate of 4,500 barrels of oil per day, indicating strong reservoir productivity.
- A mini-Drill Stem Test (DST) in the Turonian sandstone confirmed the presence of gas/condensate, with an estimated potential flow rate of up to 12,000 barrels of oil equivalent per day (boepd).
- Pressure analysis showed consistent readings with 2019 data for the Turonian reservoir but noted reservoir pressure depletion in the Cenomanian.
Background of the Afina-1x Discovery
- Location: Water depth of 1,030 meters and total depth of 4,085 meters.
- Hydrocarbon Encounter:
- Light oil with a gross thickness of 65 meters, including 50 meters of net oil pay in Cenomanian sandstones.
- Gas/condensate in Turonian sands with 10 meters of hydrocarbon-bearing layers.
- The Afina-1 well discoveries in 2019 doubled Springfield’s contingent resources to 1.5 billion barrels of oil and added almost 1 trillion cubic feet (TCF) of gas.
Operational Excellence and Next Steps
Springfield’s CEO, Kevin Okyere, expressed pride in the team’s achievements and confidence in further operational strategies to maximize production.
“Afina-1x is a vertical well, and we are confident that horizontal or alternative well completions will deliver even higher production rates. This sets an incredible platform for commercial development of both Cenomanian and Turonian reservoirs,” he said.
The appraisal marks Springfield as a trailblazer, being the first independent Ghanaian and African energy company to achieve hydrocarbon discoveries in deep-water assets.

Historical and Strategic Context
Incorporated in 2008, Springfield acquired the West Cape Three Points Block 2 in 2016, becoming its operator and majority interest holder. This appraisal solidifies Springfield’s position in the West African energy landscape and boosts prospects for future development in Ghana’s oil and gas sector.
