Аnnotation: At the geodynamic test site at the ultra-viscous oil field of PJSC Tatneft in the period 2012-2018, the results of measurements of deformations of the Earth's surface were obtained using discrete geometric leveling and continuous satellite receivers (GNSS). A comparative analysis of the results made it possible to compare the vertical component of the displacements obtained by two completely different measurement methods. The analytical model of the deformed formation made it possible to simulate the subsidence of the Earth's surface over the area of the entire deposit, while showing consistency with the results of the exceedances obtained by the leveling method. The conducted spectral analysis according to GNSS data showed the presence of a huge number of different spectra, and also allowed us to calculate the trend velocity of the Earth's surface.
