Sinopec achieves milestone with China’s deepest geothermal well in Hainan

China Petroleum & Chemical Corporation (HKG: 0386), commonly known as Sinopec, has successfully completed the drilling of the Fushen-1 Well in Hainan, which at a depth of 5,200 meters, is now China‘s deepest geothermal exploration well. This significant achievement not only highlights the technical advancements in geothermal energy exploration but also provides critical insights into the deep geothermal formation and enrichment processes in South China.

Unlocking the Potential of Hot Dry Rock

The Fushen-1 Well targets granite formations estimated to be 250 million years old. Since the commencement of drilling operations in August 2023, Sinopec has implemented several innovative technologies. These include dual-drive drilling and high-pressure injection techniques, which have allowed the company to reach the temperature limits required for harnessing hot dry rock energy, in accordance with national energy industry standards.

Pioneering Deep Geothermal Research in South China

Looking ahead, Sinopec plans to conduct extensive research and field tests at the Fushen-1 Well. The goal is to establish South China’s first integrated platform for deep geothermal research, education, and experimentation. This initiative is expected to foster the development of theoretical methods and technical systems tailored to the regional characteristics of South China, supporting China’s ambitious “Dual-Carbon” goals aimed at peaking carbon emissions before 2030 and achieving carbon neutrality by 2060.

Impact on Energy Structure and Environmental Benefits

Deep geothermal energy, characterized by its stability, reliability, and low environmental impact, offers promising prospects as a renewable energy source. It holds significant potential for large-scale development due to its vast reserves and widespread distribution. According to recent geological surveys, China’s underground hot dry rock resources could equate to 856 trillion tons of standard coal. Harnessing just 2% of these resources could fulfill China’s energy needs multiple times over.

Sinopec’s Role in Advancing Geothermal Energy

Sinopec has been at the forefront of developing and utilizing geothermal energy within China. With a geothermal heating capacity covering nearly 100 million square meters and several extensive heating projects in operation, the company is positioning itself as a leader in this sector. In addition to setting over 50% of the industry standards, Sinopec contributed to the creation of China’s first international geothermal association standard and hosted the 7th World Geothermal Congress (WGC2023) in Beijing.

Sinopec’s breakthrough in drilling the deepest geothermal well in China is a testament to the company’s commitment to renewable energy innovations. This venture not only enhances Sinopec’s reputation as a pioneer in geothermal technology but also significantly contributes to China’s energy sustainability efforts. The ongoing development and exploration projects will likely play a crucial role in shaping the future of energy consumption in China, steering the country towards a more sustainable and environmentally friendly energy structure.
