About 30 percent of Russian oil and natural gas have been reported to be buried under Sakhalin: 2.7 billion barrels of oil in 11 oil fields, 1.261 trillion square meters of natural gas in 18 gas fields and 2.5 billion tons of coal in 52 mines as confirmed until recently, according to the Korea Trade-Investment Promotion Agency (KOTRA)’s office in Vladivostok, Russia. Such quantity of oil and natural gas can satiate demand of South Korea for three years and sixty years, respectively.

Skyrocketing oil prices since 2000 have triggered global companies to dive into the oil and natural gas fields in Sakhalin. The so-called “black rush” was initiated by Exxon Mobil which started digging up 100,000 tons of oil a day in the Sakhalin Oil Field 1 in 2005. For discovery of the “black gold,” not only major global oil companies such as Exxon Mobil, Royal Dutch Shell and BP, but also government officials from countries around the globe including China, India, Japan and Turkey are paying frequent visits to Sakhalin.
