Paper describes applicability of radar data from ENVISAT (C-band, 5.6cm) and ALOS (L-band,
23cm) satellites for estimation of Earth surface deformations of oil wells in Western Siberia. Complex
analysis of temporal and spatial decorrelation depending on different wavelengths, condition and time of
acquire is done. Criteria of scene selection for digital elevation models (DEM) and displacement maps
construction are defined based on analysis and allowing getting precise results. Method allowing
detecting displacements, caused by Earth crust blocks movements as a result of oil extraction is
developed. Example of radar interferometry application for estimation of deformations of Samotlorskoe
oil well surface using results of precise leveling on Samotlorskiy geodynamic polygon during 2007-08 is
given.
Keywords: radar interferometry, DEM, displacements, geodynamic polygon, ENVISAT, ALOS
