Sinopec Achieves Record 5,300 Meters Depth in Shale Gas Well
Sinopec Breaks Record with New Well Depth Achievement
China Petroleum & Chemical Corporation (HKG: 0386, "Sinopec") has reached a groundbreaking achievement in shale gas exploration with its Project Deep Earth. This initiative, which focuses on the Sichuan and Chongqing Natural Gas Base, has produced impressive results through its Tiebei 1HF well, registering a phenomenal daily output of 314,500 cubic meters of industrial gas. The well's vertical depth has surpassed 5,300 meters, setting a new benchmark for vertical depths of shale gas wells throughout the region.
Impact on Gas Reserves and Production Efficiency
This monumental exploration endeavor is poised to significantly enhance gas reserves and production efficiency in the Puguang area. It plays a vital role in advancing the development of ultra-deep shale gas within the Sichuan Basin, where the Puguang gas and oil field holds the title of the first extra-large deep and high-sulfur gas field in the nation. Over the last two decades, this field has undergone efficient development, providing a solid foundation for future advancements.
Tackling Challenges in Ultra-deep Exploration
In pursuing a long-term strategy for stable shale gas production, Sinopec is actively exploring new resource opportunities, particularly in the Upper Permian formations. However, most of the exploitable resources reside within ultra-deep fields more than 4,500 meters below the surface, categorized as a "forbidden zone" due to rapid sedimentary velocity changes. To overcome these challenges, Sinopec has dedicated substantial resources to research and technological advancements. They have achieved a 100 percent drilling encounter rate for high-quality shale in horizontal sections, boasting precision likened to "threading a needle in the depth of the earth." This meticulous approach culminated in the successful drilling of the Tiebei 1HF well.
Innovative Fracturing Techniques
Sinopec’s self-engineered 175 MPa ultrahigh-pressure (UHP) fracturing equipment is revolutionizing the field. This technology dynamically optimizes parameters on-site, tailoring strategies to each section of the well. By creating a "man-made gas road" in the challenging high-pressure strata of 5,300 meters, Sinopec can effectively retrieve resources from the farthest depths of the gas reservoir, significantly enhancing development yields.
Future Exploration Plans
Currently, Sinopec Zhongyuan Oilfield is laying out an expansive exploration and development strategy for Upper Permian shale gas in Puguang. This plan aims to facilitate the efficient transformation of resources and bolster the company’s role in shaping the energy landscape as it continues to champion high-quality development in China’s shale gas industry.
Significance for China’s Energy Landscape
The exploration and development of shale gas holds paramount strategic significance for China’s energy sector. Sinopec has been at the forefront of this initiative since discovering the Fuling shale gas field in 2012, which catalyzed the commercial development of shale gas nationwide. The company's relentless efforts are steering the direction of the shale gas industry toward sustainable and efficient growth.
