1. NUMERICAL MODELING OF WELLBORE INSTABILITY (TENSILE FAILURE) USING FRACTURE MECHANICS APPROACH

» ABSTRACT     When a well is drilled, the equilibrium in situ stress is changed. In order to support the stress relief induced by the drilling and to prevent hydrocarbon influx into the cavity, the borehole is filled with a fluid. These operations create new stress configurations. The main point in…Continue Reading »
