Abstract:



Purpose.
Environmental safety evaluation and geodynamic monitoring of the Karachaganak oil and gas condensate field (KOGCF) explored on the north board of the Pre-Caspian depression in order to predict the consequences of long-term operation of this field.


Methodology.
Synthesis and system analysis of the articles and archival literature on environmental hazards and geodynamic monitoring of the complex methods, repeated levelling process, GPS-measurements, high-precision gravimetry and seismological monitoring.


Findings.
At a qualitative and quantitative level, the activation of vertical and horizontal movements of rock masses, changes in the field of local gravity anomalies, more frequent earthquakes whose hypocentres are located at depths comparable to the intervals of field development are substantiated. Trends and tendencies in the study on the relationship between the continuously changing geodynamic state of the subsoil and field-geological processes are outlined. All these manifestations in one way or another find manifestations in the environmental risks of the area of the exploited deposit. In the conclusions, it is recommended to carry out a set of measures to reduce environmental risks.


Originality.
The results of geodynamic monitoring at the KOGCF for the northern board of the Pre-Caspian depression for the first time made it possible to obtain convincing evidence in favour of noticeable seismic-deformation processes in the upper part of the earths crust under the influence of hydrocarbon production processes.


Practical value.
The conclusions obtained in the work confirm the necessity and binding of geodynamic monitoring in order to study and assess the possibility of different scenarios of geodynamic situations related to the development of hydrocarbon fields, are recommended for levelling factors of potential geodynamic risk at the KOGCF.
