Synopsis

This book covers a unique combination of scientific research and the practical demand for subsidence monitoring techniques focused on the satellite radar interferometry technique (InSAR). It covers the topic in a generic way: both precision and reliability of InSAR as a measurement technique, and the estimation of earth surface deformation in the presence of multiple deformation causes are addressed. It provides a review of existing subsidence estimation methodologies using geodetic measurements, explains Persistent Scatterer InSAR (PSI), and proposes a new method for reliability assessment: multi-track datum connection. The presented methodologies are demonstrated for the entire northern part of the Netherlands and a part of Germany (covering ~15.000 km2), using multi-track SAR observations from ESA's ERS and Envisat satellites. The capability of PSI for wide-scale monitoring of subsidence rates of several millimeters per year in a rural area (which implies a low PS density) is shown. Additionally, methodologies for a better discrimination of the deformation signal of interest, subsidence due to hydrocarbon production, are assessed. Essential for operational use, the performance of PSI with respect to the leveling technique is quantified. It is shown that the high spatial and temporal observation density of PSI moreover contributes to the understanding of subsurface processes. For example, subsidence due to gas extraction and subsequent uplift due to underground gas storage is clearly detected.

About this title

Synopsis

This book investigates the applicability of satellite radar interferometry (InSAR) for deformation monitoring, in particular subsidence due to hydrocarbon extraction. It covers the subject in a generic way, from the precision and reliability of InSAR as a measurement technique to the estimation of the deformation signal of interest in the possible presence of multiple deformation regimes. This book requires a background in geosciences and is designed for both researchers and the industry, since it translates the research results into the operational use of InSAR for subsidence monitoring. It gives an overview of the Persistent Scatterer InSAR (PSI) theory, and subsequently focuses on the accuracy of the estimates. For the reliability assessment of InSAR deformation estimates, which is essential for operational use, the multi-track datum connection procedure is introduced.Moreover, methodologies to improve knowledge on the physical properties of the measurement targets (the PS) are addressed, for a potentially better discrimination of the deformation signal of interest.

The presented methodologies are demonstrated in an integrated way for the entire northern part of the Netherlands and a part of Germany (covering ~15.000 km2) using real ERS and Envisat data. The capabilities of PSI for wide-scale monitoring of subsidence rates of several millimeters per year in a rural area (which implies a low PS density) are shown. Moreover, it is demonstrated that the temporal observation density of PSI provides new insights in hydrocarbon reservoir behavior. For example, subsidence due to gas extraction and subsequent uplift due to underground gas storage is clearly detected.
