Japan’s oil and natural gas resources

This article mainly introduces Japanese oil and natural gas resources.

Oilfields and gas fields exist in Japan, but large-scale gas fields are only for the south Kanto gas field, oil fields are for small scale, production is not large. In the 2000s, production is mainly conducted in Akita prefecture and Niigata prefecture, but it is less than 1% of domestic consumption, most of consumption is imported from the Middle East etc. Under the lessons of oil shock, oil reserves are started, stockpiling bases are being constructed and operating in various places.

In the Nihon Shoki, there is a description that “Burning water (fuel water)” was presented to Emperor Tenyo from Echigo country. It is said to have been produced from Tessai city in Niigata prefecture today. Crude oil naturally bleeding was called “odor water, herbal water (female water)”. In addition, it still remains as place name in various places including Akiwa-ku Niigata City and Agano-shi Niigata prefecture. The full use of these domestic oil fields has been on since the Meiji Period.

As the consumption of oil increased in the 20th century, securing it became a problem. The United States is the main importing country, and the oil embargo (ABCD enclosing network) therefrom contributed to the opening of the Pacific War, leading to securing oil fields to the Dutch East Indies.

After the Great War, the oil consumption has further increased, and the Middle East is the main import destination. Imports of crude oil are 99.7% and 254.6 million kiloliters of the total domestic consumption. From the top, importing partner countries account for 87% of the total from Saudi Arabia, the United Arab Emirates, Iran, Qatar, Kuwait and the Middle East region (2006). Regarding natural gas, Indonesia is No. 1 in the import destination, followed by Australia.

Since Showa 40 when Middle Eastern petroleum became available in a stable fashion, domestic oil resource development tended to be narrowing, and a small oil field was regarded as a shrinking / abandoned pit. In particular, due to the liberalization measures mentioned above, the abandonment of unprofitable oil fields became one after another, especially the small oil fields in Akita prefecture became almost destroyed (at this time, the annual output is around 250,000 kiloliters). In response to the surge in oil prices since 2004, there has been a movement to investigate and expand oil fields having stable output even on a small scale in the latter half of the 2000s, an increase of 900,000 kiloliters per year was seen every year It declined at the peak of 2008 and was about 550,000 kiloliters in 2016.

In order to suppress the influence of the international situation, it is urgent to develop “self-developed oil fields” (crude oil produced here is “self-developed crude oil”) that Japanese oil companies and trading companies acquire and develop interests abroad ing. The proportion of voluntarily developed crude oil in total crude oil imports increased to about 15% in the latter half of the 1990s, but it decreased to about 10 – 11% in the 2000s and was disclosed until 2007. It is the combined value of oil and natural gas since 2008 and it is 27.4% in 2016.

Oil Field / Gas Field
Oilfields in Japan concentrate on the Sea of ​​Japan side from Akita Prefecture to Niigata Prefecture. Currently crude oil is mined in Niigata Prefecture, the Japan Sea coast of Akita Prefecture, and Hokkaido (Yufutsu Plain) etc. Aomori Prefecture also has a crude oil spill area.

Gas field
Yufutsu oil field · gas field, Iwaki oki gas field, Mobara gas field (part of Minami Kanto gas field) etc. exist on the Pacific side. The South Kanto gas field boasts the largest natural gas reserves in Japan. Mobara gas field is a water-soluble gas field and is collected from underground water. However, due to environmental regulations, mining is not yet popular.

The gas field on the side of the Sea of ​​Japan is provided to the metropolitan area by a pipeline.

Production volume

Rank Oil field name Name of prefecture Production volume (1000 kiloliters)
1 Minami Nagaoka (Minami Nagaoka) Niigata Prefecture 180
2 Oki off Iwafune Niigata Prefecture 88
3 Yurihara (Yuriahara) Akita 68
4 Yufutsu (Yuutsu) Hokkaido 64
5 Katakai (Katakai) Niigata Prefecture 35

Oil production amounted to 979,000 kilolitres in 2007, which was the largest number in recent years, and 550,000 kiloliters in the latest 2016, which accounts for only 0.13% of the total domestic consumption.

Minami-Nagaoka Gas Field
Minami Nagaoka Gas Field (Minami Nagaoka Gas) is the largest gas field in Japan owned by INPEX. Natural gas collected from the depth of about 4,000 to 5,000 meters underground in the Koshida Hara Hill located in the southwestern part of Nagaoka City, Niigata Prefecture, is transported by pipeline to many city gas companies in Koshinetsu and the northern Kanto region It is supplied.

Teikoku Oil, the predecessor of the International Petroleum Development Teikoku, was discovered in 1979, and production began in 1984. On the southern side of the same hilly land there is a Kazaki gas field owned by oil resource development. Together with both consecutive gas fields, it is called “Nagaoka / Katakai gas field” or the name of the hilly area “Koshiro Hara gas field”.

Within the gas field mining area, there is the largest natural gas production facility in Japan “Koshiro Hara plant”, removing carbon dioxide and moisture contained in the gas and using the purified natural gas in this pipeline To Koushinetsu and Kita Kanto. The route to the Kanto is Nagaoka City – Joetsu City – Nagano City – Tojin City – Tomioka City – Konosu City – Adachi Ward. To Shizuoka branch from Togi City, Suwa City – Kofu City – Fujiyoshida City – Gotemba City – Fuji City – Shizuoka City.

In recent years, price competitiveness called “natural gas value chain”, such as supplementing shortfalls from LNG receiving base in Shizuoka and Joetsu (scheduled to start operation in 2014), due to rapidly expanding demand due to soaring price of competing energy such as petroleum Supply system is adopted. In addition, natural gas underground storage is carried out by injecting natural gas into the “Sekihara gas field” depleted in 1968 in the vicinity and responding to demand fluctuation by season and time. Since 2007, we have constructed a high-efficiency gas turbine combined cycle thermal power plant (output of approximately 55,000 kW) beside the Koshigehara plant and are doing electric wholesale supply project.

Iwafune-oki oil and gas field
Iwafune-oki oil and gas field (Iwafune ni Yukasen stain) is a marine oil and gas field located about 4 km off the west coast of Niigata prefecture. By 2014, four oil and gas fields were developed in the domestic waters of Japan, but only the Iwafune-Oki gas field has been in operation. The installation depth of the platform is about 36 meters. Petroleum resource development, Nippon Ocean Petroleum Resources Development, Mitsubishi Gas Chemical Company, Niigata Oil Development.

Yufutsu gas field
Yufuto gas field (Yufuzu gas) is the gas field in Tomakomai city, Hokkaido. Developed by Petroleum Resources Development Co., Ltd., crude oil is also produced simultaneously with natural gas (Yufutsu oil gas field). Gas is supplied to city gas companies in various places in Hokkaido such as pipeline transportation and railway freight transport, crude oil to papermaking companies, electric power companies and others. The average output per day is the data for 2004 oil: 619 kiloliters, gas: 892,000 cubic meters.

Katakai gas field
Katakai gas field (Katakana gas) is a gas field spreading all over Katakai district, Niigata Prefecture. Southern Nagaoka Gas Field spreading throughout the Nagaoka-shi Koshidan area is sometimes called “Minami Nagaoka / Katakiri gas field” due to an integral deposit with Katakai gas field.

The use of reservoirs that are mining natural gas is expanding from the initial 2,000 m underground to a large depth of around 4000 to 5,000 m. The reserves are said to be the largest in the country.

Gas flare that blows up from the top of a hill installed on the hill can also be confirmed from the Kanegoshi Expressway.
