Oil Extraction Is the process of removing crude oil from underground reservoirs so it can be refined and used. It involves several steps, technologies, and equipment, typically grouped into two main phases: primary extraction and secondary/tertiary recovery. 1. Exploration and Drilling Before oil can be extracted, companies must find it: Seismic surveys (as discussed earlier) help locate potential reservoirs. Once identified, a well is drilled using rigs to reach the oil-bearing rock. If oil is

Oil and gas extraction begins with exploration techniques like seismic surveys and drilling test wells to locate potential deposits. Drilling rigs, whether onshore or offshore, penetrate deep into the earth's crust to reach reservoirs thousands of feet below. Specialized equipment extracts the resources, utilizing pumps or natural pressure. Extracted crude oil and natural gas undergo processing to remove impurities and separate water or gas before transportation to refineries. Transportation met
