Dispersion and Heat Conduction in a Simplified Geothermal Doublet

The goal of this study is to test out the accuracy of the upscaling approach (Jinyu Tang, 2021) for a geothermal doublet. This approach tries to simulate the physical thermal dispersion. When modeling in a geothermal reservoir it would be easy if a lot of layers can be upscaled. However, when doing upscaling one can not just take an average of...

Using beamforming to maximise the detection capability of Kwintsheul’s seismic array

To run Nature’s Heat geothermal operations (Kwintsheul, The Netherlands) in a safe and efficient manner, and with the support of the local population, it is important to mitigate potential hazards. A well known potential hazard related to geothermal operations is the occurrence of induced seismicity due to injection and extraction of fluids in...

This research is intended to create an insight into the heat exchange occurring in a well and to find ideal well conditions in which the performance of the heat exchange is maximised. For demonstrating and studying these aspects the well of Grouw-01 is analysed. The well of Grouw-01 is a depleted gas well attained from Vermilion Energy and is in...

Reservoir Simulation for Play-based Development of Low Enthalpy Geothermal Resources: Application to the Delft Sandstone

As implementation of deep geothermal energy projects in the Netherlands increases, reservoir simulation for these geothermal systems stands to play a key role in understanding how these systems will behave and how large scale projects can be optimised to save cost and reduce risk. In this thesis, an extensive simulation study has been conducted...

Pressure and Temperature Interference for Geothermal Projects in Dense Production Areas: A Case Study for the Delft Area

The main objective of this study is to quantify interference effects between production and injection wells for geothermal projects that operate within the same reservoir. The secondary objective is to study the time it takes for the reservoir unit to thermally recharge after production has stopped. Two reservoir simulators are benchmarked to...

A case study of Pb-scaling in a geothermal project in the West Netherlands Basin

This research was done in the framework of the RVO project on Development of a well impairment model for predicting geothermal clogging (DIMOPREC) .<br/>The importance of developing new energy sources with lower carbon emissions than conventional hydrocarbon based energy sources has been globally recognized (Andrews-Speed, 2016). Geothermal...

Bunter Reservoir Quality for Geothermal Applications in the Zuid Holland Area.

With the continued growth of world population comes the need for more energy resources to quench the thirst of the energy insatiable world we live in. Geothermal energy is green and is a sustainable way of providing our energy needs. Formation water at depths greater than 3,000m in the Netherlands is a potential source of energy to generate...

Fracture characterisation in carbonate reservoirs for geothermal production

Subsurface energy projects carry high risk due to the lack of data available to accurately model reservoir characteristics. There is a need for high level analysis to extrapolate subsurface data from a single point (i.e. a well). The focus of this study will be on fracture characterisation in a carbonate reservoir located within the Geneva Basin...

Proxy-model for Flow and Transport in Geothermal Reservoirs

The hot water produced from a geothermal doublet possesses energy, which once utilized, the water cools down and is re-introduced back into the same reservoir at a sufficient distance using an injector well. As cold water flows through the reservoir, it acquires thermal energy from surrounding in-situ rocks. This process recurs until a...

Design and test of a heat pipe for geothermal applications

Heat pipes are typically used in the semiconductor industry. This means that the scale of these heat pipes is typically in the order of centimeters. Zijm suggests that heat pipes could be used for geothermal applications, but literature is lacking. To further investigate the geothermal application of heat pipes, a large scale heat pipe is built....

Data assimilation for geothermal doublets using production data and electromagnetic observations: Assimilation of production and EM data
