In this paper, we illustrate an approach to underbalanced
drilling (UBD) candidate selection based on damage
assessment and characterization using dynamic reservoir
simulations. A 2-phase, 2-dimensional transient reservoir
simulator (eRes UBD) using a control volume finite element
approach is used to reflect the reservoir conditions. Because of
its unstructured grid formulation, the simulator is ideally
suited for investigating near-wellbore phenomena, such as
