To be called Churchie 1A, the new well will use the nitrogen drilling system to drill down near the current well near Surat in south eastern Queensland.

After Churchie 3 flowed 20 million cubic feet per day using nitrogen drilling, Mosaic has held great hopes for re-entering previously drilled wells using this approach which, when handled correctly, causes far less formation damage than traditional drilling muds.

The Churchie 1A drill will use the 'Century 1' drilling rig, after currently completing two nitrogen-drilled wells for another explorer on an adjacent lease.
