The Institute of Geophysical Exploration held a video conference on electromagnetic monitoring of shale gas well fracturing.
On March 26, 2022, Zhang Guangda, Secretary of the Party Branch Committee of the Geophysical Exploration Institute, Chairman of the Board, and General Manager, convened a video conference with the four wide-area electromagnetic monitoring project teams currently under construction in the field.
In recent years, the Institute of Geophysical Exploration has been collaborating closely with Hunan Jishan High-Tech Co., Ltd. The domestically unique electromagnetic monitoring technology jointly developed by the two institutions has achieved remarkable results and has received high recognition and praise from project owners. The development and application of wide-area electromagnetic monitoring technology have gone through several stages: from initial technological breakthroughs to practical implementation in actual production—in 2019, it achieved its first successful application during fracturing operations on the Wei 204H36 platform. The technology has evolved from the first-generation monitoring system to the current second-generation system, and equipment upgrades have been carried out continuously. Today, this technology can more promptly reflect the distribution of fracturing fluids, enabling effective adjustments to operational parameters and providing guidance for on-site fracturing operations. Moreover, by integrating geological data into comprehensive analyses, the technology now allows for a better evaluation of fracturing effectiveness, thereby contributing technical expertise to enhance the productivity and efficiency of shale gas extraction.
Currently, the eight wells at four platforms—Ning209H72, Ning209H42, Ning209H19, and Lu203H1—where the geophysical exploration institute is conducting wide-area electromagnetic monitoring are being implemented in an orderly manner. In the future, platforms such as Yi206 and 251 will also be equipped with wide-area electromagnetic monitoring systems.
Zhang Guangda emphasized that this year, the Geophysical Exploration Institute still has a substantial workload in fracturing electromagnetic monitoring, with numerous follow-up projects already lined up. Time is tight and tasks are heavy; therefore, everyone must deeply master fracturing monitoring technologies, ensure the quality of field monitoring data, and implement comprehensive safety measures in all aspects. At the same time, we must strengthen project management and make every effort to guarantee safe production.
