Target dolomite resevoir depth approx. 2540m.
At 6am they were only at 2314m.
Nullara formation deeper again at maybe 3500ish m.

"The important thing for the Ungani North prospect is that the well is intact and the target remains highly prospective. Nothing that has happened to date gives us any reason to change our pre-drill estimate of 30 million barrels of recoverable oil from Ungani North.
We have also used this time out from drilling to run a velocity survey on the well. This has confirmed our interpretation that the target reservoir is deeper than we originally estimated, mainly due to high seismic velocities in the very hard section we have been drilling through. However, the actual structure is unaffected; the whole thing is just deeper than we thought. Once we get back to drilling we think we now have about 250 metres to go to the main target."

.....or you could roll the dice.
