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 book provides 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 as is a comprehensive comparison between analytical methods and numerical methods in modeling wellbore stability and integrity with recommendations for field applications of specific problems.
Lastly, the reference provides guidelines for researchers and engineers on future research developments that support the energy transition, such as in geothermal wellbores and CO2 storage capability. Supported by case studies throughout, this book delivers a critical tool for engineers to solve the future of wellbores.
