Satellite radar remote sensing technology is a promising tool for monitoring changes in the Earth's surface. The actuality of this technology is due to the development of the Russian space group of radar Earth observation. Radar interferometry methods allow creating digital surface models (DSM) and calculating the velocities of earth surface displacements with millimeter accuracy. The purpose of the work is to assess the possibility of using remote sensing data obtained from radar spacecraft for production tasks at oil and gas industry facilities (by the example of monitoring changes in the Earth's surface on the territory of an oil field). Open data Sentinel-1, SNAP software and PyGMTSAR library were used in this work. Differential interferometry methods were used in the calculation, such as the Persistent Scatterers Interferometry method and the Small Baseline Subset method to detect deformation of the Earth's surface with different reflectivity. As a result, DSMs and velocity maps of vertical displacements of the Earth's surface to the area of the oil field were calculated. Perspective directions of application of satellite radar sensing data and existing limitations of data processing technology are highlighted. It is concluded that the considered methods are applicable to functioning infrastructure objects with permanent reflectors. For monitoring objects under construction this technology is applicable only when installing artificial corner reflectors. The received data should be verified by geodetic measurement methods.
