What you'll learn
- Distinguish primary, secondary and tertiary recovery and screen a reservoir for EOR processes using published criteria.
- Explain residual oil trapping and use the capillary number and capillary desaturation curve to judge displacement efficiency.
- Calculate mobility ratios, areal sweep and Dykstra-Parsons vertical coverage for injection projects.
- Design a waterflood using patterns, injectivity, Buckley-Leverett and Welge analysis and the classical prediction methods.
- Monitor a waterflood with Hall plots, voidage replacement, water-oil ratio diagnostics, tracers and conformance tools.
- Explain first-contact and multiple-contact miscibility and estimate and measure the minimum miscibility pressure.
- Describe CO2 EOR practice, including WAG design, CO2 supply, recycling, utilization, associated storage and incentives.
- Evaluate hydrocarbon gas, nitrogen, gravity-stable and huff-n-puff gas injection for conventional and tight oil.
- Design a polymer flood, accounting for rheology, degradation, retention and inaccessible pore volume.
- Interpret surfactant phase behavior and design surfactant, ASP and low-salinity floods.
- Place thermal and emerging EOR methods in the screening framework and judge their limits.
- Compare EOR options economically with NPV, capital efficiency, injectant cost and pilot value, and recommend a staged plan.
