Etu Energias has confirmed a successful appraisal result at the Espadarte 7ST2 (ESP 7ST2) well in Block 2/05, located in Angola’s Lower Congo Basin.

The result was officially confirmed by the National Agency for Petroleum, Gas and Biofuels on 12 May 2026.

The well encountered eight productive intervals with total net pay of 53 m. Stabilized test flow rates reached 2,000–2,500 bbl/d, with no water production reported. Average reservoir porosity was measured at 18%, while some zones reached up to 25%.

The Espadarte 7ST2 well is part of a broader drilling campaign on Block 2/05. The programme began in July 2025 following the arrival of the SMS ESSA jackup rig in Angolan waters.

The campaign includes development wells, exploration wells and workover operations.

Block 2/05’s production period was extended through 2040 under a production sharing agreement amendment signed in 2022. The amendment also introduced new exploration obligations for the block.
