Temperature logs recorded shortly after drilling operations can be the only temperature
information from deep wells. However, these measurements are still influenced by the …

Circulation of working fluid in closed geothermal loops is an alternative environmentally
friendly approach to harvest subsurface energy compared to open hole geothermal doublet …

Subsurface temperature is a key parameter for any geothermal exploration activity. In
Germany, records of subsurface temperatures exist for approximately 11,000 wells. It is well …

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 …

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 …

Fractured aquifers are known to be very heterogeneous with complex flow path geometries.
Their characterization and monitoring remain challenging despite the importance to better …

Using cost-effective drilling microchips to collect real-time temperature distribution while
drilling is advantageous to accurately predict the variation of drilling fluid density and …

Most temperature predictions for deep geothermal applications rely on correcting bottom-
hole temperatures (BHTs) to undisturbed or static formation temperatures (SFTs). The data …

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

With some exceptions, such as fluid phase, pressure evolution, and reservoir geometry,
evaluation of CO2 retention for geological sequestration sites primarily involves well …
