May 1st | Learn from role models to enhance capabilities and shine brighter on the front lines.

Today is the International Labor Day, a festival shared by all working people. On this special day, many geophysical exploration professionals are tirelessly working on the front lines, demonstrating through their hard work that labor is the most glorious endeavor.

 

May Day long holiday,

They are on the Sichuan-Western Plateau, yet they aren't captivated by the blue sky and white clouds;

They’re in Ordos, yet they’re not drawn to the scenery of the northern frontier;

They’re on the southeastern coast, yet not for sun and sandy beaches;

Their figures appear in every corner of the city.

Yet it is not for the dazzling lights or the bustling traffic.

 

Let’s follow in their footsteps, head to the front lines of the project together, and take a look at the unique scenery.

 

The geophysical exploration project for the Yagen Hydropower Station road tunnel in Yalong River, Ganzi Prefecture, is located in the lower reaches of the Yalong River and its tributary, the Lichiu River. This area belongs to the high-altitude mountainous region of western Sichuan, characterized by towering mountains and deep canyons with rugged terrain.

The project team carried out construction strictly in accordance with the design and relevant codes and standards, successfully completing the exploration task. In this geophysical survey, a total of six transient electromagnetic (equivalent inverse magnetic flux) survey lines were laid out, providing essential geophysical evidence for evaluating the geological conditions of the tunnel and selecting the appropriate engineering solution.

 

The seismic safety assessment work for the Dazang Photovoltaic Project on Plots 7, 8, and 9 in Markam has completed field geological surveys of major fault zones. During the May Day holiday, we are currently compiling regional seismic activity data, information on major regional faults and their activity levels, as well as preparing seismic geological structural profiles of the near-field area.

 

 

The fracturing projects for Well DP126S and Well Yijin 1HF in the Daniudi Gas Field, located in Ordos, Inner Mongolia, have already been smoothly launched ahead of the holiday as part of Sinopec North China Oilfield’s first batch of projects this year. The site features a diverse landscape, with interwoven lake basins, mountainous areas, residual hills, and plains. The weather is hot and dry, and the climatic conditions are extremely harsh. Despite strong winds carrying sand and scorching sunlight, the project’s technical personnel are enthusiastically conducting wide-area electromagnetic fracturing monitoring, providing robust technical support for the fracturing operations and post-fracturing evaluations of coal-rock wells, tight sandstone wells, and coal-rock interbedded wells in the North China Oilfield.

 

 

The foundation pit monitoring project in Nansha District, Guangzhou, is located on Jinguang Avenue in Nansha District. The monitoring work for this project is divided into deep foundation pit monitoring and high-formwork support monitoring. A total of six technical personnel have been assigned to the project, and eight sets of equipment—including total stations, electronic levels, water level gauges, and inclinometers—have been deployed. Currently, the foundation pit has been backfilled, construction is proceeding normally, and monitoring activities are also normal. We are now in the process of organizing and compiling the indoor data. The implementation of this project has effectively validated the design of the support structure, provided guidance for construction, and ensured safety.

 

Geological survey work is underway for the exploration of granite reserves at the Sanjianling and Xi Yi mining areas, located in Yangxi County, Guangdong Province.

 

The 2024 Cryptic Well Holographic Electromagnetic Exploration Technology Service Project is located in Changning, Yibin. The project site features complex geological conditions, including a large construction area, rugged terrain, and dense vegetation. The project team moved onto the site for preliminary surveys in March and completed field data collection in April. During the holiday period, the team shifted to the indoor processing and interpretation phase; the results obtained will provide a solid foundation for subsequent three-dimensional processing and inversion.

 

The 2024 geological anomaly detection technology service project for well sites at depths ranging from 0 to 1,000 meters in Yibin is one of the key projects undertaken by the Geophysical Exploration Institute in 2024. Based on the specific conditions of the southern Sichuan region—where shallow geological conditions are complex and there are numerous surface drinking water sources and ecological redlines—the project team has established an integrated geophysical exploration technology system tailored specifically for shale gas drilling operations, effectively addressing the challenges of engineering geological exploration in mountainous areas with complicated geological settings. Since entering the field, the team has already completed survey tasks at several well sites. The project team maintains strict quality control throughout all stages—including field data acquisition, indoor data processing, interpretation, and map generation—to ensure data accuracy and operational efficiency. The project’s outcomes will provide technical support for environmental assessments of shale gas drilling platforms, pre-drilling design, and drilling design, thereby avoiding redundant construction and controlling investment risks associated with these platforms.

 

The special investigation and mineral resource assessment project for the mined-out areas along the S26 Dazhou-Wanzhou Expressway starts at the eastern side of Shibapan Town, Dachuan District, Dazhou City, where it connects to the Shibapan interchange of the G65 Dazu-Yuanyang Expressway. The total length of the route within Sichuan Province is approximately 50 kilometers. Several coal mines are located in the vicinity of the project area. These mines are all underground, with long histories of operation. Currently, most of these mines have been shut down, though some remain in operation. All the proposed tunnels will pass through coal-bearing strata, making the issue of mined-out areas particularly prominent.

Through analysis of regional geological survey data, the project team has gained a thorough understanding of the basic geological conditions in the work area. The survey work has now been completed, and the geological survey results have been communicated with the client, laying a solid foundation for the implementation of the next phase—geophysical exploration.

 

The Sichuan West Gas Field Production Capacity Construction Project is located in Pengzhou City, Sichuan Province, and comprises multiple stations, gathering and transmission pipelines, power lines, and water supply pipelines. After receiving the commission for soil and water conservation monitoring, the Geophysical Exploration Institute promptly established a monitoring team and rigorously carried out soil and water conservation monitoring work in strict accordance with the monitoring procedures and standards. In total, the team completed 20 on-site soil and water conservation monitoring visits and prepared 16 quarterly soil and water conservation monitoring reports, providing strong support for the acceptance of soil and water conservation measures. At the same time, the institute closely supervised the construction units to ensure that they implemented soil and water conservation measures effectively, thereby reducing soil erosion and safeguarding the environment.

 

During the holiday period, the holographic electromagnetic exploration project at the Lu 203H8 platform in Rongchang District, Chongqing Municipality, resumed operations and conducted a second re-measurement of the platform. Despite challenges such as a large construction area and significant human interference, the project team overcame difficulties in transporting, deploying, and debugging instruments and equipment. They deployed 16 transmitter systems and 100 receiver systems, ensuring both the quality and efficiency of the field data collected.

This project employs holographic electromagnetic methods to effectively analyze the spatial distribution of fractures and the dynamic temporal distribution of fracturing fluids. It provides a comprehensive assessment of the utilization status of shale gas resources and further enables precise localization and detailed exploration of fracture and fracturing fluid distributions in shale gas horizontal wells following hydraulic fracturing.

 

The work area of the wide-area electromagnetic survey project for Well Areas Fu201–Fu203 in the Yuxi Block is located mostly in Tongliang District, Chongqing Municipality. The terrain is predominantly hilly, characterized by dense vegetation and steep topography, with small cliffs appearing in localized areas, posing certain challenges to construction operations. In response to the technical challenges posed by the complex and steep geological structures in this project, the project team has completed the development of the “Wide-Area Electromagnetic Method Fine Processing and Inversion System for Identifying Complex Structures and Faults, Version 1.6.2.” The next step will be to apply for software copyright protection. To date, two papers have been accepted for publication in core journals, and one invention patent application has been filed. During the May Day holiday period, field data collection is nearing completion, marking the start of the project’s final stage. The project is now preparing to undergo completion acceptance inspection by the client organization.

 

The nine shale gas platforms located in the Sichuan-Chongqing region are situated in areas with complex topography and significant elevation differences; some of these sites are even in无人 areas. Adhering to an attitude and spirit of meticulous work, responsibility toward the company, and dedicated service to the client, the project team has overcome numerous challenges and leveraged domestically exclusive core technologies to carry out wide-area electromagnetic fracturing monitoring, evaluate well productivity, and determine the reserves in the well area.

 

From south to north, from basins to plains and then to plateaus—across our country’s vast and magnificent mountains and rivers, there are countless geophysical exploration professionals who, though not specifically mentioned, remain steadfastly at their posts.

They set out for the mountains and seas of their motherland, scaling cliffs, wading through lakes, trekking through dense forests, and crossing deep ravines. With concrete actions, they are putting into practice the Sichuan Resources Group’s special initiative of “Three Transformations and Three Enhancements,” continuously driving a great liberation of thought, a significant boost in capability, a profound transformation in work style, and robust implementation of tasks. They are deeply integrating new-quality productivity with geophysical exploration, leveraging more precise and powerful core technologies to accelerate exploration processes and enhance resource-exploration efficiency. With their sweat, they embody responsibility and commitment, and they celebrate Labor Day with diligent labor.

 

A tribute to all along.

In an ordinary position

You who work diligently and strive hard.

May all your efforts take root.

In the near future, let the flowers of our dreams bloom.

Wishing everyone a happy holiday!
