The practical advantages and limitations of discretized wellbore model
ling when coupled to full field compositional and/or thermal simulatio
ns are presented in detail. The implementation of an efficient, strong
ly coupled discretized wellbore model is first discussed, with emphasi
s on wellbore hydraulic options and run-time-saving features such as p
seudo-steady state initialization. The impact of these various aspects
are shown on typical isothermal and thermal compositional field scale
processes. The traditional sink/source modelling approach to fully co
upled wells is used as a reference case in these comparisons where app
licable. By doing so, this paper presents guidelines for the simulatio
n engineer on the use and possible misuse of discretized wellbore mode
