van Hout, Ylana (author)The fluid flow in a reservoir largely depends on faults, as faults can act like conduits or barriers. The influence of three fault parameters (permeability, thickness and angle) on the temperature and pressure behaviour of a geothermal reservoir, has been investigated by modelling a faulted reservoir in 2D in MATLAB, based on the Finite Element...bachelor thesis 2018

van Rijn, Sophie (author)This research identifies and provides a relative ranking of the parameters that control the thermal breakthrough time of a geothermal doublet. The ranking is based on simulations modelled by a three-dimensional model build in COMSOL Multiphysics with a simulation duration of 50 years. The model is a nonisothermal, isotropic, cuboid consisting of...bachelor thesis 2018

van Esser, Beer (author)In 2020 TU Delft will build a geothermal well producing enough energy to power all its faculties and a number of buildings surrounding the campus. This is done to meet the climate goals the TU set itself: an energy neutral campus by 2040. Geothermal plants are designed to produce for 30 years. After this period, by 2050, the TU has to be energy...bachelor thesis 2019

Maat, Sander (author)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...bachelor thesis 2021

van Heel, Floris (author)Hot water pumped out of the ground for purposes of geothermal energy extraction cools down after it is used in a heat exchanger. The now cold water contains minerals that undergo a shift in chemical equilibrium. This may cause the minerals to come out of solution and become sediments. When pumping the cold water back into the porous ground,...bachelor thesis 2023

Hacking, T.S. (author)High temperature aquifer thermal energy storage (HT-ATES) is an energy efficient way to store heat in the subsurface, recovery efficiencies of 60-85% have been found in earlier research. The TU-Delft is step by step changing its policies into a more environmental friendly approach and a HT-ATES system could be the next step in this process by...bachelor thesis 2017

ter Meulen, Bram (author), Lottman, Tim (author)Geothermal energy is strongly dependent on the geothermal gradient; this means that with increasing depth an increase in temperature is found. The targeted formation of our research is the Hardegsen which reaches depths of around three kilometers in the West Netherlands Basin. At three kilometers depth the temperature is around 90 C˚ which is...bachelor thesis 2016

Slangen, G.L.J. (author)When an oil reservoir is underlain by an aquifer, oil production draws the water from the aquifer upward, forming a water cone, which under adverse conditions enters in the production well leading to high water cuts. An alternative option is to produce above the critical rate from the aquifer, i.e., at such a rate that the oil cone is drawn into...bachelor thesis 2012

van Rooijen, Willemijn (author)This study investigates the thermal recharge of deep geothermal reservoirs by free convection. A coupled numerical model that is built in Comsol Multiphysics is presented in order to estimate the thermal recharge during the first 30 years of production from a typical high enthalpy geothermal reservoir. A sensitivity analysis was carried out to...bachelor thesis 2017

van den Berghe, Marjolein (author)Geothermal energy can be promising to help the energy transition. Warm water is pumped up from a geothermal well and after it is cooled down, the cold water is reinjected into the hot aquifer underground. The temperature change could cause chemical balances to be disturbed and result in precipitation on the porous medium of the aquifer. This...bachelor thesis 2023

Marelis, Arjan (author)The effect of conductive heat transfer recharge originating from the surrounding conduction dominated geothermal system on the geothermal reservoir lifetime has been reviewed during its development, by studying the effect of multiple reservoir and production parameters. A two dimensional (2D) finite volume implicit coupling strategy, using a...bachelor thesis 2017

Dhauri, Sha'ief (author)Projections show that urban areas are growing at an increasing rate and produce 60% of the global greenhouse gas emissions (United Nations, n.d.). In Europe, the thermal energy sector consumes about half of the energy resources, of which 85% is produced by fossil fuel-based energy systems (Drijver, Bakema, & Oerlemans, 2019). As a result of...bachelor thesis 2021

Crooijmans, R.A. (author)In this report is written what kind of influence oil has on the injection rate in geothermal wells. The geothermal well in Pijnacker (Ammerlaan) is used as a reference and their production water and produced oil is used in the experiments. The experiment consist of a microcell filled with beach sand in which production water with different...bachelor thesis 2013

Wegman, Tess (author)High Temperature Aquifer Thermal Energy Storage (HT-ATES) systems can be implemented to store geothermal energy, residual industrial heat and solar heat. Due to the large temperature differences between the injection fluid and ambient groundwater, buoyancy flow occurs, which causes heat losses which in turn results in poor efficiency of such...bachelor thesis 2017

The majority of this consumption is projected to account from developing countries such as India, China and other third world countries since the economy is increasing rapidly.

Atiş, Ebru (author)Due to an increase of precipitation reactions in water by temperature changes, cloggings canoccur in a geothermal doublet. A consequence of the cloggings is that the process of generatinggeothermal energy becomes inefficient eventually. Our goal is to determine which minerals playan important role in the clogging process in each part of the...bachelor thesis 2020
