Draganov, D.S. (author), Naranjo, D. (author), Polychronopoulou, Katerina (author), Weemstra, C. (author)Geothermal energy is a cleaner and more sustainable source of power, which plays a key role in the transition to a low-carbon economy. Sustainable and safe exploitation of geothermal resources, however, depends on our ability to understand and manage the associated seismic risks. In 2018, Nature's Heat geothermal project began operations in...abstract 2023

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

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

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 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

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

Rajvanshi, Ullas (author)As of 2040, Energy Information Administration (EIA) expects an increase of 28% in world energy consump- tion. 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. [3]<br/>In order to overcome this fast increase, the human...bachelor thesis 2018

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

Den Boer, C.A. (author)In the “Delft Aardwarmte Project” cooled geothermal water is planned to be injected back into the producing formation. This paper describes the mechanisms occurring during injection and he prediction of the thermal breakthrough that are studied using a reservoir simulation model developed for the “Delft Aardwarmte Project” field properties....bachelor thesis 2009

Tripathi, Anushka (author)Global energy transition is crucial in mitigating climate change. Numerous initiatives are being taken globally to achieve a carbon-neutral energy system. These goals require a complete shift from non-renewable energy sources to renewable sources like geothermal energy. These renewable sources of energy have to be constantly improved in order to...bachelor thesis 2022

De Zeeuw, J.Q. (author)Recently, an amount of methane was produced with hot water in the Ammerlaan geothermal field. The presence of methane influences fluid properties and fluid flow in the well, leading to changes in the pressure and temperature drop in the producing well. This study presents a model for non-isothermal two-phase flow in geothermal wells. In this...bachelor thesis 2012

Daarnhouwer, M.F. (author)In this thesis, the feasibility of a geothermal doublet in the former Barendrecht gas field is investigated. The aim of this work is to stay as closely as possible to the original well configuration. An IMPEXS model for the movement of the cold-water and thermal front is built to calculate the possible potential of the field. Wellbore heat...bachelor thesis 2013
