Fig. 22.15 Example from a flow model, taken from a major
North Sea field. In (a), the reservoir is filled with oil (green
colour). During production, gas from gas cap (red) will expand
and replace the oil, moving towards the well (b). In final stage
(c) the well will produce primarily gas, while the model reveals
remaining oil in the lowermost intervals, which would eventually require a new dedicated well to be produced
