China's oil resources are about 104 billion tons, and natural gas resources are about 47 trillion cubic meters. Through the analysis of oil and gas exploration in different types of basins, the law of new reserves and various methods, it is estimated that China's recoverable oil resources are 15 billion 16 billion tons, and natural gas recoverable resources are 100,000 140,000 cubic meters. According to the usual international classification standard (oil and gas enrichment), China is a country with "relatively rich" oil and gas resources among the 103 oil-producing countries in the world.
