Joint Stock Company SEVMORNEFTEGEOFIZIKA (SMNG) traces its history from 1 January, 1979 when by the order of Ministry of the Gas Industry of the USSR Murmansk Marine Geologic-Geophysical Oil and Gas Expedition was formed to provide geological/geophysical exploration for oil and gas across the Arctic Seas of the former Soviet Union, at present it is a joint stock company SEVMORNEFTEGEOFIZIKA (SMNG). At the end of 2003, the federal state unitary enterprise SEVMORNEFTEGEOFIZIKA was transformed into a Joint Stock Company SEVMORNEFTEGEOFIZIKA (JSC SMNG). In January 2016, under the RF Presidential Decree, the shares of JSC SMNG, owned by the Russian Federation in the person of the Federal Agency for State Property Management, were transferred to the Russian State Geological Company ROSGEO. The company has been changed according to present-day requirements and acquired a high level of marine geophysical operations performance which ensures reliability, quality and efficiency of the surveys over the different water areas of the World Ocean.
