I’ve been pretty busy out here the last few days. Too busy to spend much time online, so haven’t been able to post.
I was busy with work.The big project was to move the rig. We finished up one well and moved the rig over to start another one. You wouldn’t believe the amount of paperwork we have to complete in order to move this ship a couple of miles!
Checklists, checklists and more checklists! It really gets crazy.
Once we get the paperwork done so we can depart, we immediately start on the paperwork so we can arrive. We didn’t actually finish the arrival paperwork until halfway through the next day.
I still haven’t caught up with everything and probably won’t any time soon. We’re only drilling a ‘tophole’ at this location. A tophole is where the drillers just start the process of drilling a well, they won’t try to drill all the way down to the oil, they only drill down a short distance. They ‘spud in’.
I still don’t know much about what they do on the drilling side here, but here’s a simple explanation of what I think is going on. They basically just stab a big pipe (casing) down into the mud, jet it down to a certain depth, run some more pipe down inside that and then cement it up. They’ll set a well head on it that sticks up from the sea floor a few meters when they’re finished. Then somebody can come back later, stick a BOP (blow out preventer) on the well head, drill through all the cement, and actually drill down through the rocks to the target reservoir (and hopefully find some oil).
We’ll be going through the whole process again in just a couple more days when we’re due to move on to the next one. Oh joy. 😦
