Drill stem testing of the High Cliff sandstone interval yielded 16.5 million standard cubic feet of gas per day.
Arc, with partner Origin Energy, said the setting of production casing over the gas discovery in Hovea 2 means that it will now not be possible to sidetrack from this well to test the Dongara Sandstone oil pool intersected by the Hovea 1 well.
As a result the rig will be moved to drill a new deviated well (Hovea 3) from a different surface location to test the Hovea 1 oil pool.
It is anticipated that the completion of Hovea 2 and the rig move will take approximately 10 days with a further 10 days drilling to the top of the Hovea 1 oil zone.
