Technogenic impact of hydrocarbon production on modern deformation processes at the Gubkinskoye gas field

Geodynamic monitoring data from Western Siberian fields attests to the fact that hydrocarbon production has significant anthropogenic impacts on the geological environment. These impacts disrupt the subsurface rocks stress-strain state, leading to various problems. Among these are: casing failures, crossflows, gas springs, pollution of aquifers, land surface subsidence with violation of stability and reliability of oil and gas infrastructure. To ensure the industrial safety and protection of the subsoil at the Gubkinskoye gas field, a geodynamic polygon was established. This form of geodynamic monitoring facilitates repeated measurements of modern deformation processes. The study authors used a system-based approach to analyze and interpret the data of geodynamic monitoring: second-class leveling, satellite observations, radar interferometry, and operating data of field development. The results demonstrate that technogenic factor is the primary conditions for the formation of current surface deformation. The authors established a correlation between conditions for the formation of a subsidence trough of the earth's surface and dynamics of accumulated gas extractions and the reduction in reservoir pressure in the main productive layer. This paper provides an assessment of modern deformation and offers recommendations for enhancing the monitoring program.
