Severgeophyzika OJSC was established on 27 December 1995. As a successor to Pechorageophysics State Geophysical Company, it dates back to August 1941, when seismic surveys were launched in the Komi Autonomous Soviet Socialist Republic. Since 2006, the Company has been part of GEOTECH Holding.

Severgeophyzika has sufficient capacity to conduct high-quality 2D, 3D and 4D seismic surveys as well as complex local surveys in any geological and environmental conditions both on the land and in transition zones of the Timano-Pechora province, including specific areas such as swamps, rivers, mountain terrain, tundra, taiga, national parks and infrastructure-rich locations.

Severgeophyzika conducts integrated geophysical surveys (including local, prospecting and detailed surveys) at any exploration stage. The Company has prospected dozens of potential sites to subsequently discover many oil and gas fields, including the Yugid-Soplesskoye, Usinskoye, Verkhnevozeyskoye, Lekkerskoye, Yuzhno-Kyrtaelskoye, Zapadno-Kyrtaelskoye, Sandiveyskoye, Salyukinskoye, Zapadno-Synatyskoye, Bayandyskoye, Nizevoye, Makarielskoye, Schelyayurskoye, Verkhnevolminskoye, Severo-Baganskoye, Baganskoye, Yuzhno-Baganskoye, Makarikhinskoye, Bystrinskoye, Vostochno-Rogozinskoye, Yuzhno-Sandiveyskoye, Yuzhno-Oshskoye, and Severo-Kostyukskoye oilfields.

Severgeophyzika pushes ahead with the modernisation and development of its infrastructure. Seventy years of seismic surveys in the Far North, in particular the Timano-Pechora province, helped the Company gain extensive geophysical experience. The Company currently operates world-class field recording systems (over 15,000 channels) and the latest data processing as well as interpretation hardware and software.

Severgeophyzika comprises six field seismic crews, a geophysical data processing and interpretation department with a data processing centre, a geophysical lab, two maintenance bases (in Ukhta and a branch in Pechora), a production facility manufacturing box vans, a drilling rig repair shop, and a forge shop.

The Company keeps an archive of all raw field data acquired during surveys in the province. It also maintains an archive of over 3,200 reports on geophysical surveys conducted since 1941, and over 1,300 well logging reports. Severgeophyzika continues its research and development activities, maintains research databases, prepares design papers and cost sheets for geophysical surveys, and re-processes and re-interprets archived data with up-to-date software applications and hardware facilities. If required for interpretation, archived data can be retrieved and analysed. The special design of the databases ensures reliable storage and easy access to all archived information by different parameters.

Severgeophyzika employs approximately 1,000 people experienced in geophysical surveying in the Far North (tundra, forest-tundra and taiga areas).

The key customers of Severgeophyzika are the Ministry of Natural Resources and Environmental Protection of Komi Republic, Kosyuneft, LUKOIL-Komi, LUKOIL-Engineering, RN-Severnaya Neft, Gazprom Pererabotka, Northern Radiance Oil Company, Surgutneftegaz, Soyuz Oil Company, Nobel Oil, Zarubezhneft, Gornyi Oil, ArcticNeft, Dinielneft, So-Ga-Zo-Il, Luidor, Timan-Pechora Gas Company, InvestResurs, Delta-Nafta Oil Company, Dinyu, Arawak Geoservice, PechoraNefteGas, Yenisei, Recovery, Neftegeoservice, Asteronneft, Venlok-Neft, and others.

Severgeophyzika OJSC was formed in 1995 as a successor to the Pechorageophysics State Geophysical Company. Geophysical research of the Timano-Pechora province demonstrated the huge potential of geophysical methods applied to local geological surveys. About 350,000 km of seismic profiles have been explored since 1941, when the first seismic survey was conducted in the Timano-Pechora province. Today, Severgeophyzika focuses on further development of hydrocarbon production in the Komi Republic.

History of oil and gas exploration geophysics in the Komi Republic

1935–1936 – two geophysical crews (a geoelectric crew and a gravity survey crew) were operating in the Komi Republic. Both crews were affiliated with the Pechora Trust of the People's Commissariat for Internal Affairs. Those years are considered to be the start of geophysical exploration in the Komi Republic

1939 – a magnetic survey crew affiliated with the USSR People's Commissariat for Oil Industry launched exploration works in the Komi Republic

1940 – prospecting for oil and gas exploration in the Komi Republic

1941 – all separate geophysical crews in the Komi Republic were incorporated into the permanent Ukhta Geophysical Expedition based in Ukhta and subordinate to the Union State Geophysical Trust
