The oil they are reporting is condensate .
So under reservoir conditions it is not a liquid .
The hope and risk of this well is that there is good connectivity to the down dip N sands that were oil producers .
The hope is that there is a relatively high permeability pathway from the present perforations to the downdip N sands and a good water drive in the N sands .
From the previous production in the N sands it would appear that there is a good water drive .
So gas at a depleting rate may occur for sometime to be followed by oil production once the oil/gas interface reaches the perforations as we have seen in the G1 well .
We also have to appreciate that production from the N sands is a bonus from the apparent complete failure of that zone before the sidetrack .
So the success or otherwise of this zone needs to be just measured against the extra cost of drilling the sidetrack .
The risk is there is not a good low permeability pathway to the downdip N sands and we will just have mainly depleting gas production .
However there is the still the completed upper sands behind a sliding sleeve to come .
No need to use a drilling rig to bring that zone into production after the N sand reaches the end of its production life .
So the verdict of how successful this well is , will really only be seen after it has been in production for sometime .
I am still happy with my BET .
