PoC,
The 2D wasn't that accurate, it's a known problem with the geology of the area, this is why I was calling for 3D Seismic after NT-1 and NT-2, way before 3D became a plan for the project.
For me, and AEX/ARA, the 2D isn't reliable enough and that's the whole reason they are doing 3D now.
The 2D shows maybe a couple of cross section strike lines through the target(s), but 3D gives a picture of the entire target(s), their size and shape. Because it shows the shape, it could be that drilling from a different location is preferable, which is why the RNS said that the 3D was to confirm location. If they could drill from the current pad using the 2D there would be no need to confirm the location of CH-1.
I have said already that no new pad has been built, as the spud was scheduled to still go ahead in November albeit hampered by rig availability, but that does not make the 2D reliable.
Now we have few months wait, and ARA have all of the 3D to process, they 'could' easily move the location of CH-1 if they either think it will make drilling simpler (no zig-zag directional drilling), or if it would allow them to intersect more targets with the one drill (hitting some from CH-1b as well as the one's from CH-1a). It won't make any difference to the new spud date if they choose to do that, as they have plenty of time to do it now that the spud date has been pushed back.
