“Rosneft” company has finished drilling works at the most distant oil field “Chaivo” in Sakhalin, Russia. Production well O-14 is 13 500 meters deep, the drain is 12 033 long. It took them 156 days to drill the well.
We are going to join blogger russos in his tour to the Okhotsk Sea to see how they pull oil from its bottom.
Our trip to the drilling platform begins!
Shallow marine shelf of the Okhotsk Sea.
Under project “Sakhalin-1” recoverable reserves 307 million tons (2,3 billion barrels) of oil and 485 billion m3 of natural gas.
All of them are located at deposits “Cahivo”, “Odoptu” and “Arkutun-Dagi”.
Service ship on duty.
We have just landed on the platform.
Drilling platform “Orlan”, service and supply ships, reinforced concrete foundation of “Orlan” easily withstands the pressure of the ice and huge hummocks (some of them are high as a six-storey building).
“Orlan” platform was built in Japan in 1983-1984.
At the site where “Orlan” was installed with all working equipment the sea is fifteen meters deep.

Safety goes first! Electronic devices are allowed to be used only in the accomodations.
We start exploring the platform from this collection point.
The canteen also serves as a protected emergency shelter.
The food served here is plain but tasty.

Cameras are not allowed on the platform, but how would we take photos then? They attach gas analyzers to bloggers, if they start making sounds, they would have to leave the place immediately.
Explaining what a drilling well is.
The guys work on a rotational basis – 28 days, 12/12 hours.
Bloggers are ready.
There are about 100 workers on the platform.

The entire process is controlled from here.
The work is mostly automated.
It’s one of the most powerful drilling rings in the world!

The drill is at a depth of 8887 meters now.
When they extract all 8,8 km of pipes they will put a casing for oil extraction into the well.

This device is called a blow out preventor.
From here oil will go to the onshore treatment facility.
Thanks to russos for the cool photos!
