Advances in Oil and Gas Wellbore Integrity

Dear Colleagues,

Wellbore integrity is a key issue around the whole life of oil and gas drilling, production, and abandonment. Once the integrity of the wellbore is destroyed, it may cause shut-in and safety accidents, even seriously endanger the life of production wells. With the development of oil fields, well integrity plays an important role in reducing the production risk and ensuring the life of oil and gas wells. The application of real-time monitoring technology to continuously evaluate chemical and mechanical factors affecting wellbore integrity is an effective way to ensure wellbore safety in a timely manner.

This issue focuses on advanced techniques applied to well integrity testing and assessment to achieve safe and efficient production. With the development of digitalization and intelligence in the oil and gas industry, new solutions are provided for well integrity monitoring. It is one of the innovative methods of oil and gas well integrity detection to realize visualization analysis of big data through reliable signal analysis methods, such as wellbore flow parameters obtained by sensors and real-time casing monitoring.

Therefore, traditional and unconventional methods used to detect and assess well integrity are the focus of this issue. In particular, the processing method, calculation standard, and visual analysis of well-monitoring data are used in well integrity assessment. Factors may include the reliability of wellbore flow models, effective information extraction from real-time wellbore monitoring data, and coupled evaluation models involving all barrier elements of wellbore integrity. This research can be based on practical experience in the field or through detailed simulations.
