August 16, 2019: Fupage 8-1HF Well Acid Fracturing Project

The Fupage 8-1HF well is located in the southwestern part of the Dazhai Formation block in Fuling and serves as a key appraisal well within Fuling’s national-level shale gas demonstration zone. Its primary objectives are to assess the shale gas resource potential of the Lianggaoshan Formation–Dazhai Section, determine the single-well production characteristics, and systematically validate the drilling, completion, and fracturing technologies—providing critical technical support for the large-scale development of the Dazhai shale gas field in the future.

In July 2019, our company responded to the client's development and deployment requirements by efficiently organizing construction resources. We completed equipment mobilization and on-site preparations in the shortest possible time, successfully passing the client’s initial inspection during the construction readiness phase. During the critical fracturing stage—a key step in shale gas development—we fully leveraged our technical expertise, optimizing fracturing process parameters and implementing meticulous construction management to ensure the well’s successful completion and enhanced productivity.

As a pioneer in China’s shale gas development, Sichuan Host Company has consistently embraced the principles of technological innovation and lean management. Leveraging cutting-edge engineering expertise and extensive field experience, the company has continuously tackled technical challenges during the construction and development of the Fuling shale gas field, delivering significant value to its clients. The successful completion of this well not only confirms the feasibility of developing shale gas from the Daanzhai Formation but also underscores the company’s leading role in technological advancement within the shale gas industry.
