Hydrology and Reservoir Engineering research group

The Hydrology and Reservoir Engineering (HRE) research group is part of the Geological Survey of the Netherlands (GDN). HRE strives for a sustainable balance between the use and protection of water, energy, and resources. We perform this role for the benefit of future generations.

HRE works to improve our knowledge and understanding of the dynamics of subsurface systems. We work on the hydrogeological characterisation and modelling of subsurface flow, thermal and geochemical effects. We also develop tools for the design of storage, abstraction, and extraction activities. This enables public authorities and industry to make informed decisions about the balanced use of the subsurface.

Our expertise and areas of application

Our work and research facilitates the sustainable use of the subsurface and the protection of a healthy living environment. To fulfil this role, sharing knowledge and expertise about the shallow and deep subsurface is essential. We are able to accomplish this through our expertise and combined and integrated way of working.

HRE is made up of three teams looking at subsurface flow from different perspectives. Geochemistry investigates the chemical processes that occur during activities in the subsurface. Geohydrology is mainly concerned with groundwater flow in energy applications. The Reservoir Modelling and Optimisation team focuses on methods for managing subsurface reservoirs for energy production and storage. We work closely with our colleagues in Subsurface Modelling (SSM) and Geoscience and Technology (GST).

The main application areas of HRE are:

  • Groundwater quality and quantity.
  • Opportunities to use groundwater for multiple purposes.
  • Soil energy systems and geothermal energy.
  • Storage of thermal energy, molecular hydrogen, and carbon dioxide.
  • Hydrocarbon production.

Innovative research

Our innovative research is used, for example, to determine the age of groundwater. Tracers are used to track the flow of water or substances in water. In doing so, we have found that tracers can be effectively used to determine the age of groundwater. This knowledge helps us to better understand the groundwater system. It also gives water utilities insight into the potential risk of pumped water contamination. The results of groundwater surveys are publicly available to everyone through Groundwater Levels in View and Groundwater Quality in View.

Our research also helps energy companies develop strategies to optimise the efficiency, safety, and cost of generating and storing energy, including carbon dioxide. To this end, we co-developed the Everest open source model. Applications of this model include determining the best location for wells, while it can also help assess which observations are most useful and how much fluid can be injected.

Another aspect of our research is materials sustainability and risk management, with a focus on prevention, monitoring, and mitigation. Important aspects of this include groundwater mixing, subsidence, and the occurrence of chemical or biological reactions.
