No doubt, all of you have at least some notion of what Sakhalin is. A large island in the very East of Russia with bears walking along its streets and people going to work by deer and having caviar for breakfast… But all this is well-known that’s why today we decided to tell you about something that you probably don’t yet know about Sakhalin, namely how oil and gas are extracted there.
One of the two large oil projects is called “Sakhalin-1″.
The project includes the development of three oilfields: Chayvo, Odoptu and Arkutun-Dagi located on the northeast shelf of Sakhalin. The development of the first two of them is already in full swing.
The Odoptu field is located 9 km away the northeast coast of Sakhalin, near Piltun Bay.
And this is the small model of Chayvo.
The development of a field is carried out with the help of the boring rig called “Yastreb” (“Hawk”).
At the moment, “Yastreb” is the largest and most powerful in the world land-based boring rig, specially designed for the “Sakhalin-1″ by “Parker Drilling”. It was assembled in the United States in 2002, then tested, disassembled and brought to Sakhalin.
The height of this thing is about 70 m.
The offshore platform “Orlan” extracts oil as well. All year round it drills oil wells. Now there are already 21 of them. The length of the trunk of most wells is about 5-7 km.
The previous photo was made from the window of this bird. If the weather is good, it transports people to “Orlan”.
If the weather is bad, they have to shake for hours in the orange KAMAZ cars like those which can be seen at the photo.
The platform houses the minimum number of facilities intended for the preparation of the product. Only drilling and dwelling modules.
All extracted product goes to the onshore processing facility called “Chayvo”.
The purpose of this gigantic thing is to divide the product from wells into oil, gas and deposit water. The deposit water is injected back into the wells, oil and gas are stabilized and transported by the pipeline to the oil terminal.
The complex is designed to produce approximately 250 thousand barrels of oil and 22 million cubic meters of gas per day.
The storage of crude oil.
Looks very beautiful at night.
Within a radius of several kilometers from the plant it’s quite light.
From Chayvo oil goes by the underwater pipeline (about 200 km long) to the De-Kastri oil terminal (the mainland part of Russia, Khabarovsky Krai).
Storage tanks at De-Kastri.
Facilities for loading oil for its further delivery to international markets. Basically, it’s Japan and Korea.
“Sokol” (“Falcon”) is one of the world’s largest facilities for filling tankers which depart once every 3-4 days.
Special tankers with the double frame and loading capacity of about 100 thousand tons work all year round.
A few words about the future stages of the project and pictures from construction sites.
The Arkutun Dagi field is located approximately 25 km from the northeast coast of Sakhalin.
The development of this field will be carried out with help of the new offshore boring and extracting platform. Oil and gas will be transported by a new flowline to the existing onshore processing facility.
The start of operation of Arkutun Dagi is going to be held in 2014. The peak production will make up 4.5 million tonnes.
