General project description

DeepNL: Ongoing surface subsidence: how low can it go?

Extraction of fluids, like natural gas, from the Earth’s crust frequently results in surface subsidence and tremors. The cause lies in reservoir compaction, driven by the increase in effective overburden stress due to decreasing reservoir fluid pressure. However, the long-term surface impact of fluid production cannot be predicted confidently. The key barrier to obtaining appropriate models is that the physical and chemical mechanisms responsible for reservoir compaction are poorly known and quantified at realistic subsurface pressure and temperature conditions. We will quantify these mechanisms causing long-term subsidence and seismicity, to enable prediction via computer modelling.
