In this article, I will briefly introduce the main methods of oil extraction. Oil exists in layers of porous rock (accumulators). It is in these accumulators that the oil accumulates. A second prerequisite is that the accumulators must be covered by an impermeable oil and gas seal; otherwise, the gas will evaporate and the oil will eventually turn into bitumen.
To extract oil, a well must be drilled. The well enters the oil-producing stratum, and here the fun begins—the oil must be brought to the surface somehow.
