China Petroleum & Chemical Corporation (Sinopec) has successfully completed the drilling of China's deepest geothermal exploration well, the 5200m deep Fushen-1 Well in Hainan.
The milestone has revealed the mechanism of deep geothermal formation and enrichment in South China. The new breakthrough in the exploration of hot dry rock in terms of demographic region and depth is of great significance to enhance the large-scale development and utilisation of geothermal resources in South China and aid the energy structure adjustment.
The drilling goal of Fushen-1 Well is granite dated 250 million years ago. Since the exploration was launched in August 2023, Sinopec has adopted multiple independently developed innovative technologies, including the combination of dual-drive drilling and high-pression injection, to reach the temperature limit of hot dry rock stipulated by the national energy industry standards, while forming the key technologies of detection and evaluation of deep geothermal resources.
Next, Sinopec will carry out extensive research and field tests at Fushen-1 Well to establish the first platform integrating research, education, and experimentation of deep geothermal in South China, and explore to formulate theoretical methods and technical systems applicable to the region and help China to achieve the "Dual-Carbon" goal.

According to the China's geological surveys, the hot dry rock geothermal resources within the range of 3km to 10,000m underground in China's land area are equivalent to 856 trillion tons of standard coal, and if only 2% of them are extracted, they can reach 2993 times the annual energy consumption of China in 2023.
