SAR Interferometry Technique For Ground Deformation Assessment On Karazhanbas Oilfield

This paper briefly presents advantages of SAR interferometry for displacement monitoring using StaMPS/MTI software over areas of intensive hydrocarbon extraction with complicated geological conditions. The Karazhanbas field is a giant oil field in Western Kazakhstan, which was discovered over 35 years ago. The subsidence over Karazhanbas field was measured by using interferometric analysis of SAR (Synthetic Aperture Radar) archive data. The used dataset consist of 34 Envisat images acquired from 2003 to 2009. Deformation maps of the study area were produced.by using Persistent Scatterers (PS) and Small Baseline Subset (SBAS) methods In the future, the experimental results of observation will be continued with Sentinel 1A data. The archive for 2015-2016 years of Sentinel-1 mission, specifically designed for surface deformation monitoring over large areas, affords us the opportunity to further researches.
