Finite-element Modeling of Wellbore Integrity
Abstract
This chapter presents a staged Finite Element approach that simulates the pressure and temperature loads during wellbore operations, including drilling, cementing, completion, pressure testing, and injection processes, and the approach is designed to predict the likelihood, occurrence location, and severity of debonding failure (micro-annulus) at the casing–cement and cement–formation interfaces, shear failure at the cement, and the radial tensile failure. An example is presented in this chapter to illustrate the application of the approach, including inputting parameters obtained from the laboratory tests under downhole conditions, analyzing the simulation result, and evaluation of failure. Finally, laboratory tests and other measures that can improve the accuracy of the presented approach are discussed.
