Frick, Maximilian (author), Kranz, Stefan (author), Norden, Ben (author), Bruhn, D.F. (author), Fuchs, Sven (author)Mesozoic sandstone aquifers in the North German Basin offer significant potential to provide green and sustainable geothermal heat as well as largeāscale storage of heat or chill. The determination of geothermal and subsurface heat storage potentials is still afflicted with obstacles due to sparse and partly uncertain subsurface data....journal article 2022

Daniilidis, Alexandros (author), Nick, H.M. (author), Bruhn, D.F. (author)Direct Use Geothermal Systems (DUGS) are increasing their installed capacity worldwide and denser developments with multiple doublets are becoming more common. Interference between doublets therefore becomes an additional concern to subsurface uncertainties. Faults can be either barriers or conduits to flow and can affect the fluid pathways...journal article 2021

Daniilidis, Alexandros (author), Nick, H.M. (author), Bruhn, D.F. (author)Interest in direct use geothermal systems is increasing due to their ability to supply renewable, environmentally friendly heat. Such systems are mostly developed in conduction dominated geological settings where faults are often encountered. Interdependencies between physical, design and operational parameters make it difficult to assess the...journal article 2020

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
