Abstract
Knowledge of the structure controlling the flow of fluids within a reservoir is critical in many activities, such as hydrocarbon extraction and carbon capture sequestration (CCS). To this end, surface deformation are important observations that help in relating the ground motion to flow-related processes at depth. InSAR data from satellite radar sensors are gaining increasing attention for their unique technical features and cost-effectiveness. These data provide accurate displacement measurements along the satellite line-of-sight (LOS) and high spatial density (typically exceeding 100 measurement points/sqkm) over large areas, especially when advanced InSAR technique, such as PSInSAR™ are applied. There are significant advantages in combining two or more data stacks acquired along different satellite orbits in order to estimate a 2D vectorial displacements (East-West and Vertical components). In this work we highlight the importance of using two components of displacement to better constraint an inversion for a distributed source model.
