how many feet left to drill now, page-14

It took them 5 weeks to mill 105'.
I'll settle on one to two months with another couple of weeks to run the casing and cement.
The change of drill string is a cost worry.
If it has damaged the hardened connections on the drill pipes, what has it done to the casing and will they be able to run the other casing all the way. They should do a DST before they case since the casing is probably already perforated.
