1. Steam injection: Injecting steam into the reservoir to heat the oil and reduce its viscosity, making it easier to flow to the surface.
2. Gas injection: Injecting gases such as carbon dioxide or nitrogen into the reservoir to displace and push the oil towards production wells.
3. Chemical injection: Injecting chemicals such as surfactants, polymers, or alkalis to alter the properties of the oil and improve its flow characteristics.
4. Microbial injection: Injecting specially designed bacteria or enzymes into the reservoir to break down and digest the oil, making it easier to extract.
5. Thermal methods: Using techniques such as in-situ combustion or electrical heating to heat the reservoir and improve oil recovery.
6. Water flooding: Injecting water into the reservoir to maintain pressure and displace the oil towards production wells.
7. CO2 flooding: Injecting carbon dioxide into the reservoir to increase pressure and improve oil recovery by reducing the oil's viscosity and swelling it.

Thermal Recovery Techniques:
- Steam flooding: Injects steam into the reservoir to heat the oil and reduce its viscosity.
- Cyclic steam stimulation: Injects and withdraws steam into the reservoir in cycles to improve oil recovery.
- In-situ combustion: Injects oxygen or air into the reservoir to create a combustion zone that heats the oil and creates gases that push the oil towards production wells.
Chemical Recovery Techniques:
- Polymer flooding: Injects polymer solutions into the reservoir to increase the viscosity of the injected water, making it more efficient in displacing oil.
- Surfactant flooding: Injects surfactants into the reservoir to reduce the surface tension between oil and water, allowing water to flow more easily through the oil-bearing zones.
- Alkaline flooding: Injects alkaline solutions into the reservoir to react with acidic components in the crude oil, generating soaps that help to emulsify the oil and reduce its viscosity.
Gas Injection Techniques:
- Carbon dioxide (CO2) flooding: Injects CO2 into the reservoir to mix with the oil, swell it, and reduce its viscosity.
- Nitrogen flooding: Injects nitrogen into the reservoir to create a miscible zone with the oil, reducing its viscosity and improving recovery.
- Hydrocarbon gas flooding: Injects methane or other hydrocarbon gases into the reservoir to enhance oil recovery.
Other Techniques:
- Microbial enhanced oil recovery (MEOR): Uses microorganisms to produce gases and acids that dissolve minerals and improve oil flow.
- Electrical heating: Injects electrical current into the reservoir to generate heat and reduce oil viscosity.
- Hydraulic fracturing: Creates fractures in the reservoir to increase permeability and facilitate oil flow.
- Steam flooding: Injects steam into the reservoir to heat the oil and reduce its viscosity.
