Abstract
d measuring the performance of producing hydrocarbon reservoirs, for Enhanced Oil Recovery (EOR), Carbon Capture and Storage (CCS), Underground Gas Storage (UGS). Mapping surface displacement due to either fluid extraction/injection or fault reactivation, usually requires hundreds of measurement points to be detected per square km with millimetre-level precision, which is both time consuming and expensive to obtain from traditional monitoring techniques but can be readily obtained with InSAR. Moreover, advanced InSAR techniques, such as PSInSAR™ (Ferretti et al. 2001) and SqueeSAR™ (Ferretti et al. 2011), developed over the last decade, are capable of providing millimetre precision (comparable to optical levelling) and a high spatial density of displacement measurements over long periods of time without requiring the installation of equipment or otherwise accessing the study area. SAR measurements can be used to calibrate geo-mechanical models, thus constraining the subsurface deformation related to fluid extraction/injection from underground reservoirs. An example relevant to the Tengiz oil field (Kazakhstan) is briefly presented below.
