There is a tendency in the reservoir modelling community to build detailed, full-field models and the bigger the computer, the bigger the model. Although individual models now run very quickly, the turn-around times for reservoir studies have not necessarily changed over recent decades, despite the huge increases in computing power and the increased sophistication of modelling and simulation software. Often these models are not fit-for-purpose, and the decision at hand could have been made via more efficient routes. We tend, in this sense, to work at a level of maximum inefficiency.
The reason is workflow. In this section we therefore look at alternative workflows which take us away from the ‘default’ of a single detailed full-field model.
