Evolution of Plastic Zone around Inclined Wellbores Using Finite Element Simulation with Generalized Plane Strain Model
Inclined wellbore Plastic zone Finite element Elastoplastic analysis Drucker-Prager yield criterion
2010/9/8
This paper presents a specialized finite element procedure to analyze the elastoplastic response of rock surrounding an inclined wellbore. The procedure enables this special three-dimensional problem ...
