Abstract. A system of geodynamic monitoring at the V. Filanovsky field is presented. The technologies of data transfer to the processing center, their decoding from the internal format of the recorders and loading into the processing system, database organization are described. The algorithm for identifying and eliminating defects of various kinds that are inevitably present in the data during geodynamic monitoring at an existing industrial facility is described in detail. The maximum recorded variations of the slopes on the platforms for a period of 1.5 years are shown, and the measured trend speed is compared with the maximum allowable. Mathematical modeling of the stress-strain state due to the development of an oil-saturated formation over a period of 1.5 years was carried out and the maximum amplitude of the seabed subsidence was calculated. The constructed monitoring system, methods for processing and analyzing the results have been successfully put into practice and can be used to solve other similar problems.

Keywords: offshore hydrocarbon deposits, geodynamic observations, monitoring, inclinometer, deformation processes, time series analysis, processing of geophysical data, modeling, stress-strain state, Caspian Sea.
