Multiple choice

What is the primary mechanism by which thermal EOR methods, such as steam injection, work?

  1. By reducing the viscosity of the oil

  2. By increasing the interfacial tension between oil and water

  3. By altering the wettability of the reservoir rock

  4. By producing gases that help displace oil
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Thermal EOR methods work by reducing the viscosity of the oil, making it easier to flow and recover from the reservoir.
