oil extraction methods

Oil extraction involves retrieving crude oil from underground reserves. The most common method is drilling a well into an oil formation. Once the well reaches the oil, natural pressure often pushes it to the surface, but sometimes additional techniques like pumping or injecting water and gases are used to increase flow. In advanced methods, enhanced recovery techniques, such as steam injection or chemical treatments, help extract more oil from reservoirs. The extracted crude is then transported for refining into fuels and other products. These methods combine traditional drilling with innovative techniques to maximize resource recovery efficiently.
