And I also meant to mention that CT is suitable for sidetracking a well and can be fitted with a milling tool to cut through the casing if they set a whipstock to divert the path of the drill. As the existing hole is deviated by 30 degress then its easy to set off the CT to drill on a downwards track. You should take a look back on the EMR thread at a posting about PCLs annual report last year showing what looks like 3 different zones in the Nullara. One of them could very likely be an oil leg, and be the target for the CT. This is what I believe to be driving Arcs desire to use CT. If so they will also need to continue with swabbing.
