Russian Natural Gas Extraction

Russian Natural Gas Extraction

 

How does natural gas go from fields in the far eastern island Sakhalin to the system of gas pipeline ” Sakhalin – Khabarovsk – Vladivostok “?
The deposits of the Sakhalin shelf are main resource base.The Kirinskoye field has reserves at about 162.5 billion cubic meters of gas and 19.1 million tons of gas condensate . The system of gas transportation had started to work in  October 2013 when the first portion of the test gas was injected to the gas pipeline system ” Sakhalin – Khabarovsk – Vladivostok .” The projected level of gas production is 5.5 billion cubic meters per year.
The peculiarity of this field  is under water. All equipment is located at the bottom  at a depth of 90 meters. In Russian practice this method of extraction is used for the first time . Now let’s follow the path of the gas from the field to the end user.

On the first photo you see the complex on the beach. A pipe length which streched into the Okhotsk Sea is 29 kilometers.

Russian Natural Gas ExtractionThis buildings belong to the Processing Facility

Russian Natural Gas Extraction From the onshore processing facility the gas pipeline crosses almost the entire island from east to west and reaches the compressor station, which already produces gas in the gas pipeline to Vladivostok.

Russian Natural Gas ExtractionIncredibly beautiful and difficult terrain. There is a road to the Onshore course, but it long enough. Helicopter and cross-country vehicle are the main means of transportation.

Russian Natural Gas ExtractionSevere the Okhotsk Sea. Sunny wheather doesn’t mean it is warm. A maximum air temperature plus 11-15 degrees and a cold wind is blowing often. A water temperature, on it’s peak is 10 degrees!

Russian Natural Gas ExtractionBy the way, the Coast Technical Complex is designed to work with three fields of gas.

Russian Natural Gas ExtractionOne of the most interesting and unusual structures at a pipeline from the field to the compressor station is a bridge over the river Nabil

Russian Natural Gas ExtractionNear the river is an active tectonic fault. Here pipeline comes to the surface and passes through a special bridge to the other side. The total length of the bridge overhead is about 360 meters. In total, it were made ​​more than 10 water crossings.

Russian Natural Gas ExtractionThe length of pipeline from the complex to the compressor station is 145 km.

Russian Natural Gas ExtractionThe pipeline to the Sakhalin island (it is a region with high seismic activity) has gone through four areas of active tectonic faults and also along marshland (more than 60% of the territory)

Russian Natural Gas ExtractionNevertheless all the difficulties the pipeline is built and ready to use

Here are the shortest distance (about 7.3-7.5 kilometers) between the island and the mainland. Through the Strait the gas comes to the mainland and then goes in the district of Vladivostok. In general, the pipeline route crosses more than 400 water barriers  in Sakhalin and in the mainland. All underwater areas has  backup higher strength pipe.

Russian Natural Gas ExtractionAn incoming gas would be cleaned to protect the compressor station equipment from premature wear. This is done by the cyclone.

Russian Natural Gas Extraction This equipment is designed for a 9-magnitude earthquake, on each support worth seismic sensors. Another system of monitorinig was made ​​along the route. In the case of shock it is immediately clear where and what were offset

Russian Natural Gas ExtractionNow “Sakhalin” has two gas compressor unit with a capacity of 16 MWt each – they enable the pipeline to pump 6 billion cubic  meters of gas per year.

  1. “Vladimir, we cannot blackmail with the gas anymore… you know, the nasty nazis who suround Mother Russia and sleep under our beds came with the shale gas idea.”
