Wellbore Microannulus Characterization and Seal Repair: Computational and Lab Scale Modeling
… of CCS. This research aims to characterize the microannulus region of the cement sheath-steel casing interface in terms of its compressibility and permeability, as well as understand the mechanical behavior of a flaw upon repairing it with an epoxy nanocomposite material. Numerical models are …

Emergence of Delamination Fractures around Casing and Its Stability
… In this work, the comprehensive analysis for microannulus formation is presented by utilizing axisymmetric or three-dimensional poroelastic finite element models with CZM. This dissertation investigated these aspects: 1) Two and three-dimensional analysis of cement sheath integrity around …
