A demand for better understanding on wellbore stability and integrity is increasing in the global energy market where traditional oil and gas well practices are extending to CO2 sequestration, geothermal, and offshore. A comprehensive understanding of modeling and failure analysis of wellbore systems is critical to serve the common oil and gas wellbore as well as future activities. Wellbore Stability and Integrity: Models and Case Studies for Oil and Gas, Geothermal, and CO2 Sequestration gives today's engineers both the foundations and practical applications needed to mitigate common and future wellbore challenges. Organized into distinct parts, the authors start with problem-oriented and step-by-step instructions on how to model wellbore stability and integrity from fundamental elastic models before moving on to more advanced thermo-chemo-poro-elastic models. Dynamic loading and multiphase flow effects are also introduced. The authors then move to a comprehensive comparison between analytical methods and numerical methods in modeling wellbore stability and integrity with recommendations for field applications of specific problems. Last, the reference provides guidelines for researchers and engineers on future research developments that support the energy transition such as geothermal wellbores and CO2 storage capability. Supported by case studies throughout, Wellbore Stability and Integrity: Models and Case Studies for Oil and Gas, Geothermal, and CO2 Sequestration delivers a critical tool for engineers to solve the future of wellbores.
