It is known that the keen interest in nonconventional breeds collectors to which refer the Bazhenov shale of Western Siberia, domanikovy deposits of the Volga-Ural province, breed of the base is noted now. For the first time the fields connected with breeds of the crystal base have been open in a shelf zone of the republic Vietnam that was some kind of sensation in geological science. Was considered that the breeds of the base presented by metamorphic and magmatic breeds can't contain in themselves deposits of oil and gas. Today industrial deposits of UV in magmatic and metamorphic breeds of the base are open in South and North America, Europe, Southeast Asia, China, Vietnam, shelf of the Caspian Sea. However, the share of such fields, doesn't exceed 1 %. Now from deposits of the base receive about 90 % of oil of the general production of the republic Vietnam. In recent years breeds of the base are one of perspective oil-field objects. It is connected, with opening in it new congestions of hydrocarbons, considerable on stocks, gradual exhaustion of old fields of UV connected with breeds of a sedimentary cover. Results of deep and superdeep drilling, demonstrate that the base represents not monolithic impenetrable thickness, and, contains sometimes at a considerable depth from his surface, the jointed loosened zones favorable for congestions UV.
