- Yuanlu 33 Well in Bazhong City produces over 1 million cubic meters of gas daily.
- The well targets deep tight sandstone with complex structure and thin reservoir.
- Innovative techniques reduced exploration and development costs significantly.
- The project supports a 100 billion cubic meter natural gas base in Sichuan and Chongqing.
Exploration Breakthrough
Sinopec's "Deep Earth Project·Sichuan-Chongqing Natural Gas Base" has achieved a significant milestone with the Yuanlu 33 Well in Bazhong City, Sichuan Province. The well has produced a stable industrial gas flow exceeding one million cubic meters per day, marking a crucial advancement in the exploration of a new land-based area in the northern Bazhong region of the Sichuan Basin.
Technical Challenges
The target layer of the Yuanlu 33 Well is a deep tight sandstone gas reservoir characterized by a complex structure, thin reservoir, and tight lithology, which presents challenges for exploration and development. Despite these difficulties, the exploration branch company has developed innovative techniques to enhance reservoir prediction and implement high-yield zones effectively.
Cost Reduction
To address the high construction risks associated with the well's target layer, an integrated geological engineering and exploration and development team was established. This team successfully tackled drilling and testing challenges, achieving high yields through conventional perforation testing and significantly reducing exploration and development costs.
Strategic Importance
The success of the Yuanlu 33 Well further consolidates the proven resource base of 100 billion cubic meters in the Bazhong area. This achievement is vital for supporting the construction of a 100 billion cubic meter natural gas base in Sichuan and Chongqing, reinforcing the region's energy infrastructure.
