I had the most wonderful surprise when I was just about to go to bed the other day. Having completed my 5th to last hitch (which mostly involved surfing the web and watching movies -- we were between drilling runs), I found out that the hole liner they had run had not sealed properly. The liner (or casing, but the differences are not germane to this story) is a series of steel collars used to protect the freshly-drilled hole from collapsing. After we finish each drilling run, the rig runs casing or liner to the new deepest point and injects cement in between the casing/liner and the earth surrounding it.
Since the liner did not seal properly, the rig has to remove the liner, go in with a milling assembly to chop up all the pieces of the failed seal that were left behind, pull that assembly out, and then finally pick up the next set of tools for our next drilling run, and this couldn't have come at a better time for me. With just a few days left on the rig, sure! I'd love to sit around and watch more movies for those few days left! The slower they go, the happier I am.
But we found out just a few hours ago that they had decided that we had to work after all. They wanted to see the pressure downhole, and the only way they can see that is with our tools. So we had to prep our backup tools (the ones we've already prepped are slightly inaccessible right now) and then we have to go through the motions of putting them together, running them in the hole, tracking the depth of the drill bit, and reading the pressures. It's going to be a lot less work than a regular drilling run, and it's probably all going to happen during the daytime, so it doesn't affect me all that much....
but...
It still means I have to do some actual work between now and Tuesday morning. Sigh.
