Study Notes
Oil Recovery Operations
- Three stages of oil recovery operations: primary, secondary, and tertiary (Enhanced Oil Recovery (EOR))
Primary Recovery
- Four types: fluid and rock expansion, solution gas drive, gas cap drive, and water drive
- Relies on the natural energy of the reservoir to produce oil
Secondary Recovery
- Purpose: to displace more oil from the reservoir after primary recovery
- Gas injection is used to increase pressure and help push oil towards the production well
- Gas injection in secondary recovery is used to displace oil miscibly
Enhanced Oil Recovery (EOR)
- Third stage of oil recovery operations
- Involves various processes to extract more oil from the reservoir
- Examples of EOR processes: chemical injection, gas injection, microbial injection, and thermal injection
- EOR processes involve oil swelling, oil viscosity reduction, or favorable phase behavior
