Webfracturing has now become one of the key methods for rock stress estimation as suggested by the International Society for Rock Mechanics (ISRM). Fairhurst was among the first to advocate the use of hydraulic fracturing for in situ stress determination. Kirsch (1989) presented solutions from which the basic Web10 apr. 2024 · Accurate stress field calculation of the casing-cement-stratum system is crucial for evaluating wellbore integrity. Previous models treated in-situ stress as boundary pressure loads, leading to unrealistic infinite displacements at infinity. This study presents a three-dimensional (3D) analytical solution for the stress field within the casing-cement …
