Scenario: You are an engineer working on a mature oil field that has been experiencing declining production. The team is considering implementing THAI to increase oil recovery.
Task:
**1. Key factors for reservoir suitability:** * **Permeability:** The reservoir needs high permeability for air to effectively move through and displace oil. * **Geological structure:** A suitable geological structure with a defined top and bottom is required for strategic toe and heel well placement. * **Oil Viscosity:** The oil's viscosity should be amenable to reduction by air injection. **2. Potential environmental challenges and mitigation strategies:** * **Greenhouse gas emissions:** Air injection can lead to the release of methane and carbon dioxide. * Mitigation: Implementing carbon capture and storage technologies, using low-emission air sources, and optimizing injection parameters to minimize emissions. * **Soil and water contamination:** Improper injection practices can contaminate surrounding soil and water resources. * Mitigation: Utilizing robust well construction techniques, conducting thorough environmental monitoring, and implementing water injection to manage pressure and minimize contamination risks. **3. THAI for heavy oil reservoirs:** * Air injection in heavy oil reservoirs reduces the oil's viscosity, making it more mobile and easier to extract. The process essentially "thins" the oil, allowing it to flow more readily towards production wells, improving overall recovery rates.
