ExxonMobil has made a fresh oil discovery offshore Angola that will be tied back to existing infrastructure.

The US supermajor has revived investments in deepwater Block 15 after years of undertaking very little fresh work and as it seeks to maintain output from what was a highly prolific asset.

According to ANPG, Angola's upstream regulator, the new discovery is called Bavuca Sul-1, with the well drilled as part of the Block 15 redevelopment project.
