1. A commercial oil reservoir has its API gravity being 10 API. In your own word, which recovery technique will be well suited to optimize the recovery. 2. In your opinion, how can trapped phase be mobilized to be produced? 3. What is the difference between VGD and CGD during gas flooding? 4. With the aid of a diagram, kindly explain hysteresis of relative permeability curve. 5. Differentiate between Microscopic displacement efficiency and that of macroscopic. 6. From question 5 , which of these displacement efficiencies will result to a profound effect on the oil recovery. 7. What is the difference between capillary and viscous forces 8. Explain the effect of wettability on relative permeability. 9. Differentiate between mobility and Mobility control. 10. What is favorable mobility ratio and how can that be accomplished
