| Abstract: | The article presents the results of a detailed spatiotemporal comparative analysis of the data obtained by platform and bottom inclinometers at the V. Filanovsky field. The slope spectra obtained by the platform inclinometers fundamentally do not coincide with the data of the bottom sensors. It turned out that platform inclinometers effectively detect exogenic deformation effects and hardly identify deformations of the seabed associated with field development processes. Using the geomechanical poroelastic inclusion model, the authors mathematically modeled the spatial distribution of the seabed slopes during a period of intensive water injection into the developed reservoir. The proposed model shows that only the system of bottom inclinometers is a geodynamic monitoring element. It is concluded that sensor systems installed only on the platforms themselves (accelerometers, inclinometers, GNSS) do not pertain to geodynamic monitoring systems (geodynamic survey areas) and cannot ensure safe and rational subsurface use.
