Abstract The Enhanced Geothermal System in Soultz-sous-Forêts, located in the geothermal
favorable Upper Rhine Graben, is a fracture-controlled reservoir that was highly investigated …

Abstracts This paper aims to introduce a filtering concept for evaluation and optimization of
the feasibility and energy productivity for hydrothermal doublet systems. It also provides an …

Increasing the contribution of geothermal systems to green energy generation requires
designing new innovative systems producing a significant amount of thermal power in a …

Abstract Mahallat Geothermal Region, located in the central part of Iran, is known as one of
the largest low-temperature geothermal fields. In this study, Mahallat geothermal resource …

Motivated by the unknown reasons for a kilometre-scale high-temperature overprint of 270–
300∘ C in a reservoir outcrop analogue (Piesberg quarry, northwestern Germany) …

Deep closed-loop U-shaped heat exchanger with a long horizontal extension (up to 5 km) is
a new approach to harvest heat more sustainably. This system comprises two deep vertical …

Conventional methods to estimate the static formation temperature (SFT) require borehole
temperature data measured during thermal recovery periods. This can be both economically …

The Earth's interior contains considerable unused thermal energy, far exceeding the current
global energy demand. Using shallow geothermal sources for direct heating is a historically …

Global warming profoundly impacts our environment, causing ice melting, rising sea levels,
extreme weather events, ocean acidification, and habitat destruction. These changes …

Among renewable resources, geothermal energy occupies a unique position due to its base-
load capability. When mining geothermal energy resources, one of the crucial parameters is …
