Wang, Y. (author), Voskov, D.V. (author), Daniilidis, Alexandros (author), Khait, M. (author), Saeid, S. (author), Bruhn, D.F. (author)The efficient development of a geothermal field can be largely affected by the inherent geological and physical uncertainties. Besides, the uncertain operational and economic parameters can also impact the profit of a project. Systematic uncertainty quantification involving these parameters helps to determine the probability of concerning...conference paper 2020

(author), Bastesen, Eivind (author), Daniilidis, Alexandros (author), Garcia, Oscar (author), Torabi, Anita (author), Wheeler, Walter (author)Understanding fractures and fracture networks is essential for the investigation and use of subsurface reservoirs. The aim is to predict the fractures and the fracture network when there is no direct access to subsurface images available. This article presents a universal workflow to numerically compute a discrete fracture network by combining...journal article 2020

Daniilidis, Alexandros (author), Nick, H.M. (author), Bruhn, D.F. (author)As the code was actively developed during the time of publication, the published data suffer from an error with regards to the discount factor applied during the NPV calculation. The published data NPV has been calculated for periods of 100 days, while the discount rate applied was the quoted Annual Discount Rate (ADR) value of the manuscript...journal article 2020

(author)The use of the subsurface and the exploitation of subsurface resources require prior knowledge of fluid flow through fracture networks. For nuclear waste disposal, for the enhancement of hydrocarbon recovery from a field, or the development of an enhanced geothermal system (EGS), it is fundamental to constrain the fractures and the fracture...journal article 2019

Ziabakhshganji, Z. (author), Nick, H.M. (author), Bruhn, D.F. (author)Geothermal projects, as renewable energy projects, are not economically attractive in most places of the world at the current state of development; for this reason, subsidies are required by energy and environmental authorities in order to increase the interest in such projects. In this paper, we assess and model strategies for integration of...journal article 2019

Ziabakhshganji, Z. (author), Nick, H.M. (author), Donselaar, M.E. (author), Bruhn, D.F. (author)A new solution for harvesting energy simultaneously from two different sources of energy by combining geothermal energy production and thermal enhanced heavy oil recovery is introduced. Numerical simulations are employed to evaluate the feasibility of generating energy from geothermal resources, both for thermally enhanced oil recovery from a...journal article 2018

(author), van Wees, Jan Diederik (author)In this paper we present results of a global resource assessment for geothermal energy within deep aquifers for direct heat utilization. Greenhouse heating, spatial heating, and spatial cooling are considered in this assessment. We derive subsurface temperatures from geophysical data and apply a volumetric heat-in-place method to improve...review 2018

Willems, C.J.L. (author), Nick, H.M. (author), Goense, Twan (author), Bruhn, D.F. (author)This paper evaluates the impact of reduction of doublet well spacing, below the current West Netherlands Basin standard of 1000 to 1500 m, on the Net Present Value (NPV) and the life time of fluvial Hot Sedimentary Aquifer (HSA) doublets. First, a sensitivity analysis is used to show the possible advantage of such reduction on the NPV. The...journal article 2017

(author)Required distance between doublet systems in low enthalpy geothermal heat exploitation is often not fully elucidated. The required distance aims to prevent negative interference influencing the utilisation efficiency of doublet systems. Currently production licence areas are often issued based on the expected extent of the reinjected cold...journal article 2017
