A joint venture between Origin Energy and Falcon Oil & Gas has had mixed results from two separate shale oil and gas drilling operations in the highly-fancied Beetaloo sub-basin in Australia.

The two operations were production testing at the Kyalla-117 liquids-rich gas discovery well, and an exploration well on the Velkerri-76 liquids-rich gas play.

At Kyalla-117, production testing has been completed and the well shut in. There were previously reported challenges around a potential downhole flow restriction.
