Subsidence in the Netherlands - Measuring, matching, monitoring, modelling
conference paper
Subsidence in the Netherlands is an important socio-economic problem. An integrated approach is required to assist taking policy decisions which involve subsidence. In addition, subsidence estimates can help in subsurface modelling and production optimization. We have developed an integrated approach to subsidence. First, subsidence data and metadata connected to subsidence are collected and interpolated to subsidence maps. This requires comprehensive treatment of different sources of subsidence data. Then, we can apply dedicated inversion methods to quantify the causes of this subsidence. This has been demonstrated in a field study in which three components of shallow compaction were successfully disentangled. The knowledge obtained can then be used to judge different management scenarios. This is, for instance, important for decision making in groundwater management. The integrated knowledge can also be used to optimize monitoring strategies in areas where subsidence will occur as a result of future operations. This is demonstrated with a synthetic field study. The integrated approach that we follow warrants optimal use of all the available knowledge. Inversion of subsidence to quantify its causes is also important for production optimization. Better mapping of the reservoir compaction can help in improved history matching and identification of undepleted reservoir compartments.
