A drilling project in China's Xinjiang region, known as Shenditake 1, has set a new record as the deepest well ever drilled in Asia. Located in the Taklamakan Desert within the Tarim Basin, the project is being carried out by the China National Petroleum Corporation (CNPC) and aims to reach a depth of 11,100 meters, targeting rock layers from the Cretaceous period, which date back between 65 and 145 million years. As of now, the well has reached 10,910 meters, surpassing previous records in the region. The drilling process involves navigating through multiple layers of rock under extreme temperatures, which can exceed 200 degrees Celsius, and immense pressure, over 130 megapascals. The well is situated near the Fuman oil field, an area known for its deep reserves of oil and gas.
The project started in 2023 with the goal of reaching 11,100 meters within about 457 days. However, progress has slowed in recent months, with nearly 300 days needed to drill the last 910 meters. In spring 2024, the well surpassed the 10,000-meter mark, marking a significant milestone as the first vertical well in China to reach that depth. The project has already used over 1,000 drill pipes and more than twenty drill bits, illustrating the immense difficulty of drilling through extremely hard rock at such depths.
The primary goal of Shenditake 1 is to study the Cretaceous rocks to assess their potential for hydrocarbons and to gain a better understanding of deep seismic fault behavior. Direct sampling from such extreme depths is rare, and this project provides a unique opportunity to study rock formations that are typically only inferred through indirect methods like seismic surveys. The data collected from this well could improve models used to locate potential oil and gas reserves and enhance understanding of how deep faults behave in the region.
While the Soviet Union's Kola Superdeep Borehole remains the world's deepest well at 12,262 meters, achieved between 1970 and 1989, Shenditake 1 is not primarily aimed at breaking records. Instead, it focuses on industrial and scientific exploration, targeting specific geological formations for resource assessment. The Chinese well will fall short of the Kola well's depth by over 1,000 meters, but its targeted approach reflects a shift toward practical applications rather than purely experimental drilling.
China's deep drilling efforts in Xinjiang are part of a broader strategy by major oil companies to explore deep energy resources. For example, Sinopec has already drilled 49 wells deeper than 8,000 meters in the nearby Shunbei field. This indicates that Xinjiang has become a key area for testing and advancing ultra-deep drilling technologies. These projects not only serve commercial interests but also demonstrate China's growing industrial and technological capabilities in the energy sector.
