8. Use designing procedures - theoretical, laboratory tests, and field pilots.
9. Plan and implement EOR processes employing the proper empirical, analytical, and simulation tools.
10. Forecast rate-time and recovery-time behavior under various EOR methods and analyze reservoir performance.
11. Assess risks and ways to minimize their impact on project economics.
12. Monitor reservoir/well behavior.
