The target Dongara Sandstone was intersected at a depth of 2756m, about 7m higher than in the original discovery well.
It took 13 days to drill Apium-2 to a total depth of 2812m.
Arc as operator is moving the CDL Rig-18 from the well to the Canning Basin, where it will begin its highly-anticipated drilling program.
Arc and Origin hold equal stakes in the L1 licence and Apium-2 well.
