The temperature is rising again in Namibia’s Orange basin, the world’s hottest new hydrocarbon hunting ground, with Upstream told that early signs from Shell’s Jonker-1 exploration probe are promising.

Northern Ocean’s semi-submersible rig Deepsea Bollsta began drilling the high-profile well in Block 2913A in mid-December.

The probe is chasing a different geological play to the Upper Cretaceous light oil discoveries made last year by Shell's Graff-1 and La Rona-1 exploration wells.
