    yatchy is right. Oil is only going to flow to surface if the pressure is enough to overcome the weight of the oil column.

    Same way that most water wells don't flow to surface, they will only do so if the pressure is high enough to make them artesian wells. Yet water wells still produce water by pumping it to the surface - same with oil wells.

    So if the problem is pressure, it's not really a big deal. Fit a pump jack and the well will flow.

    If the problem is permeability, things are more complicated because it means the oil is not flowing into the well - not that the pressure is just too low to bring flowing oil to surface. But logs are pretty good at picking perm and very good at picking porosity, so I tend to think the permeability is probably alright here.

    Reservoir pressure seems more likely to be the culprit here, especially since it's so much shallower than Mereenie.

    I would love to see the DST chart. That would explain everything. If the flow rate is good, but the reservoir pressure is below the hydrostatic pressure, then this well just needs a pump.

    If the reservoir pressure is fine but there's no flow, then it's time for a frac.

    One quick look at the chart will tell CTP which it is, in fact they should have been able to release that info already. Hopefully it will come in a later announcement.

    So as I said before, the geology is fine. It's the company I'm worried about.
