Oil Extraction Techniques

Oil extraction involves several techniques to obtain crude oil from the Earth. The primary methods include: 1. **Traditional Pumping**: A well is drilled into an oil reservoir, and the natural pressure forces oil to the surface. Pumps often aid extraction when pressure decreases. 2. **Secondary Recovery**: Water or gas is injected into the reservoir to maintain pressure and push more oil to the surface. 3. **Enhanced Oil Recovery**: Advanced techniques, such as heating or using chemicals, are applied to extract additional oil not reachable by conventional methods. These methods ensure efficient and optimal extraction of oil resources.
