PROBLEMS

1.1 Define saturated and undersaturated reservoirs. Explain the differences
between saturated and undersaturated reservoirs.
1.2 Explain the main differences between oil and gas reservoir fluids.
1.3 Draw and label completely phase diagrams (P T diagrams) for under-
saturated oil, undersaturated gas condensate, and saturated oil
reservoirs.
1.4 What are the main assumptions of black-oil, modified black-oil (MBO),
and compositional PVT models?
1.5 What are the main differences between black-oil and MBO models?
1.6 Give example applications for compositional PVT models.
1.7 Define vaporized oil gas ratio and solution gas oil ratio.
