Phase-field analysis of fracture in heterogeneous wellbore systems: effects of casing eccentricity and cement-formation interface strength
Tharunsarathy Sachithanantham, Wasim Niyaz Munshi, Chandrasekhar Annavarapu +1
Predicting the initiation and propagation of cracks in heterogeneous wellbore systems under complex in-situ conditions remains challenging. We present a hybrid phase-field fracture…
