Integrated Geomechanical Modeling of Casing Failure; From Lab to Simulation, Ph.D. Dissertation Sharif University of Technology ; Pak, Ali (Supervisor) ; Shad, Saeed (Co-Supervisor)
Abstract
Casing failure is one of the mainly problems of hydrocarbon fields that may cause wells out of service and impose heavy costs on oil companies. There exist many theories that may cause casing failure including: the plastic behavior of surrounding formations, the effects of reservoir depletion, over-pressured formations, weak cementing operations, fault activation, and local stresses applied on casing. In salt-rich formations, creep behavior can be the main cause of casing failure, too.The purpose of this study is to evaluate the causes affecting casing failure via experimental studies and numerical simulation with the focus on the conditions governing south-west Iranian oil fields, where the...
