Springfield Exploration and Production completes Afina Well Appraisal

Springfield Exploration and Production (SEP) Limited and its Partners, Ghana National Petroleum Corporation (GNPC) and GNPC EXPLORCO have announced the successful completion of the appraisal well test activity of the Afina discovery by a re-entry of the well.

Afina-1x drilled in 2019 is located at a water depth of 1030 metres and was drilled to a total depth of 4085 metres. It encountered light oil with a gross thickness of 65 metres, with 50 metres light net oil pay in good quality Cenomanian sandstones.

A statement from the company said the secondary target drilled at the edge of the structure and contained in Turonian age sands encountered 10 metres of hydrocarbon-bearing sands consisting of gas/condensate.

The Afina-1x Drill Stem Test (DST) carried out on the Cenomanian sandstone flowed at a maximum rate of 4500 barrels of oil per day confirming good reservoir productivity on the upper end of pre-test expectations.

Pressure transient analysis also indicates reservoir pressure depletion at the reservoir level as compared to 2019 pressures indicating depletion through production.

A mini-DST conducted on the Turonian sandstone confirmed the presence of gas/condensate and indicated an estimated flow rate potential of up to 12,000 Barrels of oil equivalent per day (boepd).

Pressure transient analysis from this reservoir showed the pressures consistent with the pressures collected in 2019.

The Deepsea Bollsta was released on 22nd November 2024 at midday and it set sail from Ghanaian waters the next day at 2.30 pm.

Chief Executive Officer of Springfield, Kevin Okyere said:“We are extremely happy with the results of the appraisal programme which has further confirmed our understanding of our geological, geophysical, reservoir models and demonstrated our operational capacity.”

“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 provides an incredible platform for reaffirming commercial development options for the Cenomanian and Turonian reservoirs.

I would like to take this opportunity to thank the Springfield team and Northern Ocean’s Deepsea Bollsta crew and all service partners for conducting this activity safely and on schedule.”

“With the successful completion of this appraisal well-test activity, Springfield continues to make history as the first Independent Ghanaian and African Energy Company to operate a deep-water asset and find hydrocarbons,” he added.
