Wide-area electromagnetic fracturing monitoring technology boosts the efficient development of tight gas reservoirs.
At a critical juncture of profound transformation in the global energy system, tight gas—a strategic unconventional natural gas resource—plays an important strategic role in ensuring national energy security and advancing the achievement of the “dual carbon” goals through its efficient development.
Relying on wide-area electromagnetic fracturing monitoring technology, the fracture monitoring team of the Geophysical Exploration Institute continues to deepen its technological innovation and engineering practice in the development of tight gas reservoirs. On March 20, the team was invited to hold a special technical exchange meeting at the Fracturing Command Center in the Tongnanba Well Area of the Puguang Branch of the Zhongyuan Oilfield. At the meeting, the team systematically summarized the industrial application results of wide-area electromagnetic monitoring technology in the Tongnanba tight sandstone gas reservoir, providing a scientific basis for subsequent optimization of fracturing processes and the formulation of development plans.
This technical exchange meeting was hosted by the Tongnanba Project Department and attracted project leaders and relevant experts from numerous organizations, including the Oil Production Engineering Institute, the Geological Research Institute, the Gas Testing Team, the Fracturing Engineering Team, the Measurement and Control Technology Center, and the Continental Shelf Development Company. The fracturing monitoring team from the Geophysical Exploration Institute delivered a systematic presentation titled “Application Practice of Wide-Field Electromagnetic Method in Fracturing Monitoring of Tight Sandstone Gas Reservoirs,” covering topics such as technical principles, data acquisition methods, interpretation model development, and multi-well validation. By showcasing monitoring data and application cases from several typical wells in the Tongnanba well area, the team elaborated in detail on the technical advantages of the wide-field electromagnetic method in identifying fracture geometry, assessing reservoir stimulation volumes, and predicting fracturing effectiveness—providing innovative solutions for the precise development of “sweet spot” areas in tight gas reservoirs. The attending experts fully endorsed the advantages of wide-field electromagnetic monitoring and encouraged the team to continue their research and tackle ongoing challenges, thereby providing technical support for the efficient development of tight gas reservoirs.
The successful holding of this technical exchange meeting marks the entry of wide-area electromagnetic fracturing monitoring technology into a new stage of deepened application in the development of tight gas reservoirs. Taking this conference as an opportunity, the fracturing monitoring team at the Institute of Geophysical Exploration will focus on advancing three key technological research areas:
First, establish a dynamic prediction model for fracture propagation based on multi-physics field coupling to enhance the physical interpretability of monitoring data.
Second, develop an AI-assisted interpretation system to achieve automated and intelligent output of monitoring results.
Third, build a multi-dimensional database integrating “geology, engineering, and monitoring” to provide data support for optimizing tight gas reservoir development plans.
In the future, the team will continue to implement the “Technology-Driven Empowerment” strategy. By leveraging both technological innovation and engineering practice as twin driving forces, we will steadily enhance the intelligent level of tight gas reservoir development, thereby making new and greater contributions to ensuring national energy security and promoting the efficient exploitation of unconventional oil and gas resources.
