First EAGE Workshop on Surface Logging

12-14 November 2025 | Paris, France

1. Fundamentals of Surface Logging

Fundamental mudlogging techniques emphasize the extensive use of instrumentation and essential technologies, playing a crucial role in modern drilling operations and providing preliminary formation evaluation data. Studies should demonstrate the value of basic mudlogging technologies across various scenarios and environments, while also addressing the limitations that advanced surface logging services aim to overcome

2. Drilling Performance

Techniques for evaluating drilling efficiency, detecting formation changes, and identifying lithological variations through surface data, with a focus on optimizing drilling performance and operational effectiveness.

3. Mud Logging Practices 

Techniques and new technologies for formation evaluation, identifying, detecting, and measuring fluids and lithology with the various basic and advanced technologies, highlighting the growing relevance in various environments from conventional to unconventional in different scenarios (O&G and new energy). How surface logging can mitigate or solve operational risks and costs, increasing the reliability and predictability of the characterization of rocks and reservoir fluids.

4. Integration of Surface Logging with Subsurface Data

Integrating surface logging data with downhole measurements to enable real-time decision-making during critical drilling operations, enhancing the speed and accuracy of responses.

5. Applications In Reservoir Evaluation & Geochemistry

Leveraging surface logging to estimate key reservoir properties such as porosity, permeability, and fluid content, improving the precision of reservoir characterization and development strategies.

6. Operational Safety and Hazard Identification 

Examining the role of surface logging in the early detection of well control issues, abnormal pressure zones, and loss circulation. By improving safety measures, surface logging mitigates operational risks and enhances overall safety.

8. Energy Transition

Exploring surface logging’s growing relevance as the industry pivots toward more sustainable and diverse energy sources.

9. Case Studies

Showcasing real-world applications of surface logging across diverse environments, including unconventional reservoirs, high-pressure high-temperature (HPHT) wells, deepwater drilling, geothermal exploration, and special gas exploration (hydrogen and helium).
