With cooling to −162°C at normal atmospheric pressure, natural gas becomes a liquid and its volume is reduced by a factor of around 600 times. LNG is a clean, colourless and odourless liquid, the density of which is about half that of water.
The implementation of Phase 1 of the project began in 1996. The
The first Russian natural gas liquefaction plant was put into service in February 2009. The plant’s output is contracted for the next 20 years to customers from Japan, South Korea and North America.
Offshore wells, including development wells, water injection wells, drill cuttings
Oil and gas straight out of the well contain impurities like water and sand which need to be removed at the platform prior to sending the oil and gas via the offshore pipeline to the OPF which further processes the pre-treated feedstock, compresses it and sends it to the south.
The north of the island where oil and gas are produced has severe climatic conditions preventing access by conventional means of transport. To support operations throughout the year, crude oil and natural gas need to be taken to the south of the island. This required the construction of the TransSakhalin pipeline system to carry oil and gas across the island to Aniva Bay in the south end which remains practically ice-free in winter allowing for the year round navigation.
Production facilities at Prigorodnoye near Korsakov include an LNG plant and an oil export terminal (OET). At the LNG plant, gas received via pipelines from the north is liquefied and then stored in two high-capacity storage tanks. Oil is stored in two other specially designed storage tanks at the oil export terminal.
Gas and oil tankers are loaded at the Prigorodnoye port to carry the cargo to customers. Now the terminal handles around 160 gas and 65 oil tankers per year.
