In a drilling update, Origin said the Emu Apple-2 well, in the Redcap Block of ATP 470P, encountered good oil shows in the Boxvale Sandstone and the basal Evergreen Formation.
As a result, the well was cased and suspended as a future Boxvale Sandstone oil producer.
The Mitchell 152 rig then moved to the Emu Apple-2 well location, where drilling began yesterday morning.
These two appraisal wells come 18 months after the oil field was discovered with the Emu Apple-1 wildcat.
Emu Apple-2 is located 400m northwest of the discovery well, while Emu Apple-2 is 420m to the southwest.
Interests in the drilling program are Origin’s wholly owned subsidiary Angari Pty Ltd 67.5%, Origin Energy CSG Ltd 22.5% and Santos QNT Pty Ltd 10%.
