Methods of Enhanced Oil Recovery (EOR)

Three primary techniques of EOR:

1. gas injection

2. thermal injection

3. chemical injection

Gas injection, which uses gases such as natural gas, nitrogen, or carbondioxide (CO₂), accounts for nearly 60 percent of EOR production inthe United States.

For Net ZeroAficionados - there’s Plenty of room in the North Sea (UKCS) for Sequestration and Injection of that "nasty" CO2

For HeavyOil Recovery there are new EOR Techniques on the horizon – Beyond Thermal Steam Stimulation(TSS) !!......

The results of solving these problems by combining thermal steam and physicochemical stimulations and using “cold” technologies involving thermotropic gel-forming and oil-displacing systems…..
