Shell has made a barnstorming offshore oil discovery in Namibia’s prolific Orange basin that looks to be far bigger than its two earlier oil finds in probably the world’s top exploration play.

QatarEnergy and state-owned Namcor, Shell’s partners, today confirmed Upstream’s recent exclusive that the Jonker-1x probe had hit light oil in Block 2913A, but did not go into detail.

However, informed sources told Upstream that the Jonker discovery is jumbo-sized, fully justifying Shell’s decision to focus on a new geological play in the block as opposed to going back to drilling in the area of last year’s Graff-1x and La Rona-1x discoveries.
