On the potential of insar for estimating crude oil volume changes from the deformation of storage tanks

In this article, we examine the possibility of using the interferometric phase on some fixed corners of storage tanks to infer the tank fill ratio. For the study, we use floating roof tanks for which the fill ratio can be inferred from the floating roof position. We observe a correlation between the phase double difference taken at the fixed roof of neighboring tanks and the fill ratio double difference. We highlight some challenges that require further investigation and the development of adapted InSAR techniques.
