Mansour Pour, K. (author), Voskov, D.V. (author), Bruhn, D.F. (author)The energy transition is inevitable since approximately two-thirds of the current global GHG emissions are related to energy production. Subsurface can provide a great opportunity for innovative low-carbon energy solutions such as geothermal energy production, hydrogen storage, carbon capture, and sequestration, etc. Well and borehole...journal article 2023

Suherlina, Lily (author), Bruhn, D.F. (author), O Saar, Martin (author), Brehme, Maren (author)The primary goal of this study is to build new and integrated conceptual models for a high temperature field in Indonesia. Providing new data, combining models, visualizing them in 3D is significant to refine previous 2D traditional models, which are limited for reservoir characterization and wellplacement.

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 large‐scale storage of heat or chill.

Yeates, Christopher (author), Schmidt-Hattenberger, Cornelia (author), Weinzierl, Wolfgang (author), Bruhn, D.F. (author)Designing low-cost network layouts is an essential step in planning linked infrastructure. For the case of capacitated trees, such as oil or gas pipeline networks, the cost is usually a function of both pipeline diameter (i.e. ability to carry flow or transferred capacity) and pipeline length. Even for the case of incompressible, steady flow,...journal article 2021

Kluge, C. (author), Blöcher, Guido (author), Hofmann, Hannes (author), Barnhoorn, A. (author), Schmittbuhl, Jean (author), Bruhn, D.F. (author)The hydraulic performance and mechanical stability of open fractures are crucial for several subsurface applications including fractured geothermal reservoirs or nuclear waste repositories. Their hydraulic and mechanical properties (fluid flow and fracture stiffness) are both strongly dependent on the fracture geometry. Any change in...journal article 2021

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

Wang, Y. (author), de Hoop, S. (author), Voskov, D.V. (author), Bruhn, D.F. (author), Bertotti, G. (author)Multiphase mass and heat transfer are ubiquitous in the subsurface within manifold applications. The presence of fractures over several scales and complex geometry magnifies the uncertainty of the heat transfer phenomena, which will significantly impact, or even dominate, the dynamic transport process. Capturing the details of fluid and heat...journal article 2021
