This paper presents geodynamics of the Southern Cis-Urals region. It focuses on seismicity induced by hydrocarbon production by summarizing the published case studies. Natural and man-made changes in bowels of the Earth are usually accompanied by tectonic movements and deformations of earth's surface, which is one of the important factors determining environmental changes and requiring mandatory consideration in engineering-geological surveys and exploitation of deposits. The influence of anthropogenic factors on the geodynamic state of platform areas is considered by the example of Orenburg oil and gas condensate field and Baitugan oil field.

The article raises a problem of dangerous geodynamic processes taking place in the eastern part of Orenburg region. The analysis of subsoil geodynamic state of Orenburg region is completed. Effective monitoring of geodynamic processes in the eastern part of Orenburg region using a seismological network is proposed and justified. Seismic events with a magnitude of ML> 2.0 are confidently recorded on this territory as well as subsidence of land surface reaching 50 cm per year. According to long-term monitoring of seismic events in the eastern part of the Orenburg region, a repetition schedule of seismic events was constructed. It allowed us to make a conclusion of the reason for increased geodynamic activity in this region is high technogenic load on geological environment. To study abnormally high seismic activity in the East Orenburg region, it is necessary to create a seismological network of 3-4 seismic stations in the territory of seismic activity in the Gaysky and Novooorsky districts near the cities of Orsk and Gai, Iriklinskaya State District Power Station and Iriklinskoye Reservoir. This will help to identify seismic activity causes and sources, level of danger, help to develop measures for reducing seismicity and increase the security of specific objects of society, industry and energy.
