The drilling will firm up exactly whats there - nobody really knows the structure depths.

All targets have come in significantly higher than initially prognosed, though TD still stands at around 2500m to test the horizons. I dont believe they can go too much lower than 2500m with hunt rig 2 without downsizing the drilling pipe, though that being said, I dont think theres much below the warburton.

Theres been a few little surprises so far anyway and hopefully the tirrawarra lends itself to a significant one.

Heres some information about another well that intersected the tirrawarra a few years ago....
_________________________________________________________

The well intersected two oil saturated sandstones within the Patchawarra Formation. The deeper sandstone was penetrated towards the base of the first core cut over the basal Patchawarra/Tirrawarra interval. A recovery of 16 barrels of light oil (equivalent to 192 bopd flow rate) accompanied by 1 mmcfd gas was made from the drill stem test of the sandstone unit. The upper sandstone exhibited excellent fluorescence and gas shows from a 4 metre sandstone but was not tested. Two additional cores were cut into the Tirrawarra Sandstone/Merrimelia Formation. A second drill stem test was conducted over the Tirrawarra Sandstone and recovered 4 barrels of light oil accompanied by 0.25 mmcfd gas. The pressure charts from the test suggested formation damage inhibited hydrocarbon inflow to the well. Porosity and permeability data from the cores indicated the reservoir quality of the Tirrawarra Sandstone was similar to that encountered at Flax 1.

Wireline log analysis identified 11 metres of oil/gas pay in the Patchawarra Formation and 9 metres in the Tirrawarra Sandstone. On 13th July, the well reached a total depth of 2786 metres and was cased and suspended as a future oil producer.
