China National Petroleum Corp. (CNPC) has commenced drilling the Shendi Chuanke 1 Well in Sichuan province, China, with the aim of reaching a depth of 10,520 meters (approximately 6.5 miles). This marks the second time this year that China has undertaken drilling to such extreme depths, as the country seeks to explore ultra-deep reserves of natural gas.

In May, CNPC began drilling a similar-sized well in Xinjiang, which was described as the deepest ever undertaken in China. The Xinjiang project was more experimental in nature, focusing on testing drilling technologies and gathering data on the Earth's internal structure. However, the current undertaking in Sichuan has a different objective: to locate ultra-deep reserves of natural gas.

Sichuan province is renowned for its spicy cuisine, breathtaking mountain landscapes, and giant pandas. It also houses some of China's largest shale gas reserves. State-owned oil companies in China have faced challenges in fully exploiting these reserves due to difficult terrain and complex underground geology.

With a focus on enhancing fuel security, China's government has been encouraging energy companies to increase domestic production in response to power shortages, geopolitical tensions, and global price fluctuations. The search for ultra-deep natural gas reserves is part of the country's efforts to boost domestic energy production and strengthen energy security.
