The Groningen gas field in the Netherlands is Europe's largest gas field. It
has been produced since 1963 and production is expected to continue until
2080. The pressure decline in the field causes compaction in the reservoir
which is observed as subsidence at the surface. Measured subsidence is
characterized by a delay at the start of production. As linear compaction
models cannot explain this behavior, alternative compaction models (e.g.
Rate Type Compaction Model and Time Decay model) have been investigated that
may explain the measured subsidence. Although the compaction models
considered in this study give a good match to this delay, their forecasts
are significantly different. Future measurements of subsidence in this area
will indicate which type of compaction model is preferred. This will lead to
better forecasts of subsidence in future. The pattern of over- and
underestimation of the subsidence is similar for the compaction models
investigated and tested. The pattern can be explained by differences in
modeled porosity and aquifer activity illustrating the improvement of
subsurface knowledge on the reservoir using subsidence measurements
