FAQ

Q: What is enhanced oil recovery?
A: Enhanced oil recovery (EOR) is a process used to extract additional oil from reservoirs.

Q: Why is enhanced oil recovery necessary?
A: Enhanced oil recovery is necessary to maximize oil production from existing reservoirs and improve overall oil recovery rates.

Q: What are the different methods of enhanced oil recovery?
A: The main methods of enhanced oil recovery include thermal methods (such as steam injection), gas injection methods (such as carbon dioxide injection), and chemical methods (such as polymer flooding).

Q: How does steam injection work in enhanced oil recovery?
A: Steam injection involves injecting steam into the reservoir to heat the oil and reduce its viscosity, making it easier to recover.

Q: What is carbon dioxide injection in enhanced oil recovery?
A: Carbon dioxide injection involves injecting carbon dioxide into the reservoir, which can help to displace and push the oil towards production wells.

Q: What is polymer flooding in enhanced oil recovery?
A: Polymer flooding involves injecting polymer solutions into the reservoir to improve the sweep efficiency and displace the oil.

Q: What are the benefits of enhanced oil recovery?
A: Enhanced oil recovery can increase an oil field's production, extend the field's life, and improve the overall recovery of oil in place.

Q: How widely used is enhanced oil recovery in North Dakota?
A: Enhanced oil recovery techniques are commonly used in North Dakota to maximize oil production from its fields.

Q: What is the role of the North Dakota Industrial Commission in enhanced oil recovery?
A: The North Dakota Industrial Commission regulates and oversees the implementation of enhanced oil recovery projects in the state.

Q: Are there any environmental concerns associated with enhanced oil recovery?
A: Some environmental concerns associated with enhanced oil recovery include the potential for groundwater contamination and carbon dioxide emissions.
