Shale is actually the most difficult to drill because it's water sensitive, meaning it leads to unstable holes. So I think the downhole problem they experienced was in the shale where the hole caved on them. Now they are side-tracking back down to the same area, but have not indicated that they will do anything different. I hope they use a different drilling fluid. Either way, I have to be honest that I think its really unlikely we will see TD before year end. Just look at the progress and the previous updates. Its not realistic.
