What is the primary difference between cyclic steam injection and steam flooding as thermal EOR methods?
- Cyclic steam injection involves injecting steam in cycles, while steam flooding involves continuous steam injection (correct)
- Cyclic steam injection is a type of in-situ combustion, while steam flooding is not
- Cyclic steam injection is a chemical EOR method, while steam flooding is a thermal EOR method
- Cyclic steam injection is only effective for shallow oil reservoirs, while steam flooding is effective for both shallow and deep reservoirs
What is the main purpose of in-situ combustion as a thermal EOR method?
What is the main purpose of in-situ combustion as a thermal EOR method?
- To inject chemicals into the reservoir to improve oil recovery
- To create a combustion front that heats the reservoir and reduces oil viscosity (correct)
- To inject steam into the reservoir to displace oil towards production wells
- To increase the temperature of the reservoir and reduce oil viscosity
