Intensity of oil extraction in the Caspian region is growing each year. Rich resource potential of the Caspian Sea is the reason for further development of its deposits by huge oil companies. But the development of oilfields on the Caspian shelf is carried out in difficult conditions. It is ecologically sensitive zone with shallows and ice formation, high reservoir pressure (over 80 MPa) and big containing of hydrogen sulfide (over 20 %). Because of these problems extraction of the oil on the Caspian has some points, directed to the opposition to specific features of the Caspian Sea. In this article there are main and modern ways of extraction, which differ from used earlier, because they are directed on the safety of ecological situation of the sea and not polluting it.
