The distribution of crude oil is extremely unbalanced in general: from the perspective of the eastern and western hemispheres, about 3/4 of the oil resources are concentrated in the eastern hemisphere, and 1/4 in the western hemisphere; from the perspective of the northern and southern hemispheres, the oil resources are mainly concentrated in the northern hemisphere; from the perspective of latitude distribution, they are mainly concentrated in the two latitudes of 20°-40° and 50°-70° north latitude. The two major oil regions of the Persian Gulf and the Gulf of Mexico and the North African oil fields are all located within the latitude of 20°-40° north, which concentrates 51.3% of the world's oil reserves; the 50°-70° latitude zone contains the famous North Sea oil fields, the Volga and Siberian oil fields in Russia, and the Alaska Gulf oil region. 1. The Middle East Persian Gulf Coast The Middle East Gulf region is located at the hub of Europe, Asia, and Africa, and is very rich in crude oil resources, known as the "world oil depot". According to the latest data from the American "Oil and Gas Magazine" in 2006, the world's proven crude oil reserves are 180.49 billion tons. Among them, the proven reserves of crude oil in the Middle East are 101.27 billion tons, accounting for about 2/3 of the world's total reserves. Among the top ten countries in the world in terms of crude oil reserves, five are Middle Eastern countries, namely Saudi Arabia, Iran, Iraq, Kuwait and the United Arab Emirates. Among them, Saudi Arabia has proven reserves of 35.59 billion tons, ranking first in the world. Iran has proven reserves of 18.67 billion tons of crude oil, ranking third in the world.

2. North America The countries with the richest crude oil reserves in North America are Canada, the United States and Mexico. Canada has proven reserves of 24.55 billion tons of crude oil, ranking second in the world. The United States has proven reserves of 2.98 billion tons of crude oil, mainly distributed along the Gulf of Mexico and the Gulf of California, with Texas and Oklahoma being the most famous. Alaska is also an important oil producing area. The United States is the world's second largest oil producer, but due to excessive consumption, it still needs to import a large amount of oil every year. Mexico has 1.69 billion tons of proven crude oil reserves, making it the third largest traditional crude oil strategic reserve country in the Western Hemisphere and the sixth largest oil producer in the world.

III. Europe and Eurasia Europe and Eurasia have 15.71 billion tons of proven crude oil reserves, accounting for about 8% of the world's total reserves. Among them, Russia has 8.22 billion tons of proven crude oil reserves, ranking eighth in the world, but Russia is the world's largest oil producer, with an oil output of 470 million tons in 2006. Kazakhstan in Central Asia is also a country with relatively rich crude oil reserves in the region, with proven reserves of 4.11 billion tons. Norway, the United Kingdom and Denmark are the three countries with the richest proven crude oil reserves in Western Europe, with 1.07 billion tons, 530 million tons and 170 million tons respectively, among which Norway is the tenth largest oil producer in the world.

IV. Africa is the region with the fastest growth in crude oil reserves and oil production in recent years, and is known as the "second Gulf region."

In 2006, Africa's total proven crude oil reserves were 15.62 billion tons, mainly distributed in the Gulf of Guinea in West Africa and North Africa. Experts predict that by 2010, the proportion of African countries' oil production in the world's total oil production is expected to rise to 20%. Libya, Nigeria, Algeria, Angola and Sudan rank in the top five in Africa's crude oil reserves. Nigeria is the largest oil producer in Africa. At present, the oil production of Nigeria, Libya, Algeria, Angola and Egypt accounts for 85% of Africa's total production.

V. Central and South America Central and South America is one of the world's important oil production and export regions, and is also one of the regions with the fastest growth in crude oil reserves and oil production in the world. Venezuela, Brazil and Ecuador are the countries with the richest crude oil reserves in the region.

In 2006, Venezuela's proven crude oil reserves were 10.96 billion tons, ranking seventh in the world.

In 2006, Brazil's proven crude oil reserves were 1.61 billion tons, second only to Venezuela. The crude oil resources in the Campos and Santos basins in the southeastern waters of Brazil are the main components of Brazil's crude oil reserves. Ecuador is located in the northwest of the South American continent and is the third largest oil producer in Central and South America. It is rich in oil resources, mainly concentrated in the eastern Amazon Basin. In addition, there are also a small number of oil fields in the western peninsula of Guayas Province and Guayaquil Bay.

Six, Asia-Pacific region The proven crude oil reserves in the Asia-Pacific region are about 4.57 billion tons, and it is also one of the regions with the fastest growth in oil production in the world. China, India, Indonesia and Malaysia are the countries with the richest proven crude oil reserves in the region, with 2.19 billion tons, 770 million tons, 580 million tons and 410 million tons respectively. Although China and India have rich crude oil reserves, they still need to import a large amount every year. Due to their superior geographical location and rapid economic development, Southeast Asian countries have become emerging oil producers in the world. Indonesia and Malaysia are the most important oil producers in the region. Vietnam also replaced Brunei in 2006 to become the third largest oil producer and exporter in Southeast Asia. Indonesia's Sumatra Island and Kalimantan Island, and Malaysia's offshore Malay Basin, Sarawak Basin and Sabah Basin are the main crude oil distribution areas. my country's oil resources are concentrated in eight basins, namely Bohai Bay, Songliao, Tarim, Ordos, Junggar, Pearl River Estuary, Qaidam and East China Sea Shelf, with recoverable resources of 1.72 billion tons, accounting for 81.13% of the country; natural gas resources are concentrated in nine basins, namely Tarim, Sichuan, Ordos, East China Sea Shelf, Qaidam, Songliao, Yinggehai, Southeast Qionghai and Bohai Bay, with recoverable resources of 18.4 trillion cubic meters, accounting for 83.64% of the country.
