Abstract
Oil or gas fields and associated facilities are computer simulated by solving linear algebraic equations using a Schwarz method with at least one well node included in the overlap. According to another aspect, equations for the wellbore nodes are processed to eliminate some non-pressure variables, e.g. component compositions. Other features are also provided.
