what's being done in the last 1 week

a few friends have commented before that I don't blog about my work at all. Well, the explanation was simple. 'Cos it's another world altogether out here, in terms of the technical words use, the little known operations, the life etc.

BUT I will attempt to try to tell you something about my work bah. Will try to keep it simple. My colleagues would be interested in what's happening to the well anyway.....

First and foremost, this is what we drill into the sea. The red thing is a blow-out preventor. THe white and blue thing is the wellhead. That's the beginning of the piping system into the reservoir. The piping system that we run into the hole after drilling is called casing. We divide the well into a few hole sections. Drilling from a big diameter into a smaller one.

This is the drilling machine that we used to drill the hole. Top-drive.

The bit that is used for drilling. There are a few types though. For the previous hole section, we used this tri-cone. For the current hole section, a polycrystalline diamond bit is used instead. Yup, the hole section gets smaller as we drill deeper and the formation gets more difficult.

The long, brown pipes is called the drill pipes. They are used for drilling into the hole. After that the bit and the pipes are pulled out and a permanent casing is runned into the hole instead.

haha.. I will back with more pictures in the next few days. They are currently drilling the high pressure section. It was pretty exciting when they were putting in (actual term: tripping in) a new drill pipe and the rotating stops. Most influx of gases occur during then. A metre cube of gas at 3km deep when coming up the hole will result in a massive blowout if not properly dealt with as early as possible due to the increasing density as it raises. Not many wells are high pressured wells in the world. Mostly in the north sea..... guess I am really lucky that I am able to witness this while training.

Since this morning, we had a 'stucked pipe' problem. The entire 3km of drill pipes are stucked in the hole. The actual reason has yet to be established though. They were jarring (pulling the string up and down) for a good 4 hours with zero results. Although half of me wished that they would be able to get the pipes back to rotation, the other half of me wished that more would go wrong so that I would be able to learn more stuff. =PpPp evil huh?

oh well... hopefully, something good comes out of this. =) time for the weekly safety meeting! hehe... 17 more days!!!!!!!
