Leaders from Chongqing Shale Gas Exploration and Development Co., Ltd. visited the Yuxi Wide-Area Exploration Project Department of the Geophysical Exploration Company to inspect and provide guidance on the work.

On March 24, 2022, an inspection team consisting of six members—including Tu Zhong, Deputy General Manager of Chongqing Shale Gas Exploration and Development Co., Ltd.; Zhang Haijie, Head of the Exploration and Development Department; Lei Bin, Deputy Head of the Quality, Safety, and Environmental Protection Department—visited the Comprehensive Analysis Project Office for the Causes of Low Resistivity in the Longmaxi–Wufeng Formation at the Jiangye Tan 1 Well Area in the western Chongqing region (hereinafter referred to as the “Project Office”). This project is undertaken by Sichuan Zhongcheng Coalfield Geophysical Engineering Institute Co., Ltd. (hereinafter referred to as the “Geophysical Institute”). The working area is located in Bishan District and Jiangjin District of Chongqing Municipality. The primary task is to carry out wide-area electromagnetic surveys covering a total length of 307.9 km around the Jiangye Tan 1 Well Area, with the aim of studying the spatial distribution of low resistivity in the target shale gas strata, investigating and comprehensively analyzing the causes of low resistivity, and further refining favorable areas based on electrical parameters to provide technical support for the comprehensive evaluation and selection of such areas.

The project team inspects the site.

The inspection team listened to and reviewed the project’s construction design plan, received a briefing on the project’s progress, conducted a standardized safety inspection of the project department, carried out safety and technical quality briefings, provided on-site training and examinations on safety and technical quality, and also examined the status of the wide-area electromagnetic survey instruments and equipment as well as the preparation of materials. The inspection team unanimously concluded that the project’s construction design plan is reasonable and meets the requirements of this work; the project department has a sound organizational structure, a reasonably composed staff, a relatively complete safety standardization system, thorough preparatory work, sufficient availability of instruments, equipment, and materials, and a well-planned construction schedule—thus possessing all the basic conditions necessary to successfully complete this project.
