Springfield Exploration and Production (SEP) Limited, along with its partners Ghana National Petroleum Corporation (GNPC) and GNPC EXPLORCO, has completed the appraisal well test activity for the Afina discovery.
This marks a significant milestone in the exploration and development of the Afina field, which is located offshore in Ghana’s oil-rich Deepwater Tano/Cape Three Points block. The appraisal activity is critical in assessing the commercial viability and potential of the Afina discovery, as it helps determine the quality of the reserves, flow rates, and overall productivity of the field.
The successful completion of the well test is an important step in moving toward the development phase of the Afina field. It is expected to provide valuable data that will inform decisions related to drilling plans, reservoir management, and field development strategies.
The Afina discovery has the potential to contribute significantly to Ghana’s oil and gas sector, and the successful completion of this appraisal test sets the stage for further development and production activities. SEP, GNPC, and GNPC EXPLORCO will likely continue to monitor and assess the findings from this well test to optimize future production and maximize the economic benefits of the discovery for Ghana.
Springfield Exploration and Production (SEP) Limited, in partnership with Ghana National Petroleum Corporation (GNPC) and GNPC EXPLORCO, has completed the appraisal well test for the Afina discovery. This achievement marks a critical step in the exploration and development of the Afina field, which is in the offshore Deepwater Tano/Cape Three Points block in Ghana.
The appraisal well test is essential for assessing the commercial viability of the Afina field. It provides crucial insights into the quality of the reserves, the flow rates, and the field’s overall productivity, all of which are necessary to determine whether the field can be developed profitably.
This successful completion signals progress toward the development phase of the Afina field. The data gathered from the well test will help inform decisions on drilling plans, reservoir management, and field development strategies. The findings from the test will also help guide the partners in optimizing future production, to maximize the field’s economic benefits for Ghana.
The Afina discovery holds significant promise for Ghana’s oil and gas sector, and the completion of the appraisal well test paves the way for future development and production activities. SEP, GNPC, and GNPC EXPLORCO will likely continue to assess and monitor the data to ensure the Afina field reaches its full potential, contributing to Ghana’s energy sector and broader economic growth. The recent Drill Stem Test (DST) conducted on the Cenomanian sandstone of the Afina field confirmed promising production capabilities, with a maximum flow rate of 4,500 barrels of oil per day (bopd). This result highlights the potential of the field to produce significant amounts of oil, which is an important step in confirming the commercial viability of the Afina discovery.
Additionally, pressure transient analysis revealed that there has been reservoir pressure depletion since 2019, suggesting that the reservoir has been actively producing oil. This information is vital for understanding the reservoir’s behaviour over time and will help in planning further development and optimization of the field.
The positive flow rates and the insight into the reservoir’s pressure dynamics provide confidence in the future production capabilities of the Afina field, marking a significant milestone in its development. These findings will be critical for shaping the field development strategies and drilling plans as SEP, GNPC, and GNPC EXPLORCO continue to move forward with the exploration and production phases of the project. In addition to the promising results from the Cenomanian sandstone, a mini-DST conducted on the Turonian sandstone also confirmed the presence of gas and condensate in the reservoir. The test estimated a flow rate potential of up to 12,000 barrels of oil equivalent per day (boepd), indicating the significant potential of the Turonian reservoir to contribute to the field’s overall production.
Furthermore, the pressure levels recorded during this test were consistent with those measured in 2019, which reinforces the stability and reliability of the reservoir. This stability is crucial for ensuring long-term production and optimizing reservoir management strategies, as it suggests the reservoir can maintain its performance over time.
The combination of favourable results from both the Cenomanian and Turonian sandstones positions the Afina field as a highly promising asset for Springfield Exploration and Production (SEP), GNPC, and GNPC EXPLORCO. These findings will help inform the partners’ field development and production planning as they continue to assess the full potential of the discovery. The appraisal program for the Afina discovery concluded successfully with the release of the Deepsea Bollsta rig on November 22, 2024. The rig left Ghanaian waters the following day, marking the end of the operation. This milestone marks a significant step in advancing the Afina field toward its development phase.
Kevin Okyere, CEO of Springfield Exploration and Production (SEP), expressed his satisfaction with the results of the appraisal program, highlighting the program’s success in validating their geological, geophysical, and reservoir models. He also noted the program’s demonstration of the company’s operational capacity in executing complex field evaluations.
Okyere further shared optimism about the potential for even higher production rates, stating:
“Afina-1x is a vertical well; we are confident that a horizontal well or other well completion options that maximise reservoir exposure in the fields would deliver much higher production rates.”
This confidence in the ability to enhance production further positions the Afina field as a highly promising asset for SEP and its partners, GNPC and GNPC EXPLORCO. The successful conclusion of the appraisal phase provides critical data to inform future drilling and development strategies aimed at optimizing output and maximizing the economic benefits of the Afina field for Ghana.
Kevin Okyere, CEO of Springfield Exploration and Production (SEP), emphasized that the successful conclusion of the appraisal program provides an incredible platform for reaffirming commercial development options for both the Cenomanian and Turonian reservoirs. These results will serve as a solid foundation for further advancing the development of the Afina field, confirming its commercial potential.
Okyere also expressed gratitude to several key stakeholders involved in the operation. He thanked the Springfield team, the Northern Ocean’s Deepsea Bollsta crew, and other service partners for their collective efforts in completing the appraisal activity safely and on schedule. Their collaboration and commitment were crucial in ensuring the success of the program.
This achievement highlights Springfield’s ongoing dedication to pioneering advancements in Ghana’s energy sector and further strengthens its position as a key player in the country’s growing hydrocarbon industry. The successful appraisal of the Afina field underscores Springfield’s ability to contribute significantly to the nation’s oil and gas sector, positioning the company for continued success as it moves toward commercializing its discoveries and maximizing its economic impact.
