3D displacement estimates due to deep-seated hydrocarbon production in Groningen from satellite radar interferometry, 2015-2023
What's in it
This dataset provides 3D ground displacement estimates for the Groningen gas field area estimated from InSAR observations. The displacement vectors are derived using an augmented strapdown decomposition method, which estimates physically meaningful displacement components using ascending and descending InSAR Line-of-Sight (LoS) observations. The strapdown approach enables so-called “3D-global / 2D-local” solutions by incorporating minimal but meaningful contextual information about the expected physical behavior and/or spatial geometry of the deformation field [1]. The method defines a local reference system with transversal, longitudinal, and normal (TLN) directions, with motion only occurring in the transversal-normal (TN) plane. The method allows for the incorporation of a prior uncertainty in the local frame orientation, enabling the propagation of this uncertainty to the final displacement estimates. This supports cartographic visualization using vector fields with confidence ellipses, enhancing interpretability. See for a full description of the method [2].
