Springfield completes Afina Well appraisal; commercial viability confirmed

Springfield Exploration and Production (SEP) Limited, in partnership with the Ghana National Petroleum Corporation (GNPC) and GNPC EXPLORCO, has successfully completed the appraisal well test of the Afina discovery through a re-entry of the well.

The successful completion of this appraisal well-test reinforces Springfield’s historic role as the first independent Ghanaian and African energy company to operate a deep-water asset and achieve hydrocarbon discoveries.

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.

Moreover, 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 are consistent with the pressures collected in 2019.

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.

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

“We are extremely happy with the results of the appraisal program 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”, Chief Executive Officer of Springfield, Kevin Okyere said.

“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”, he added.

About Springfield E&P

Springfield Exploration and Production Limited was incorporated in March 2008 to pursue exploration and production opportunities in Ghana and the West African sub-region.

The process of acquiring a block began in 2012, but the Government of Ghana finally awarded it in March 2016.

The Company is currently the Operator and Majority Interest Holder of West Cape Three Points Block 2 with the Ghana National Petroleum Company and its exploration wing, GNPC-explorco holding the remaining interest.

In October 2019, the Afina-1 well made two discoveries that included gas, condensate and light oil at a water depth of 1030 metres.

The discovery more than doubled Springfield’s contingent resources on the Block to 1.5 billion barrels and added almost 1TCF of gas to the existing discoveries.
