Understanding NMR relaxometry of partially water-saturated rocks [PDF]

open access: yesHydrology and Earth System Sciences, 2015
Nuclear magnetic resonance (NMR) relaxometry measurements are commonly used to characterize the storage and transport properties of water-saturated rocks. Estimations of these properties are based on the direct link of the initial NMR signal amplitude to

Temperature sensor module for groundwater flow detection around borehole heat exchangers

open access: yesGeothermal Energy, 2018
We present a temperature sensor module (TSM) for detecting the groundwater flow velocity and direction in the vicinity of a borehole heat exchanger (BHE). We demonstrate the method for double U-tube BHEs, which can also be applied to coaxial BHEs.

Geothermal Energy: Tapping the Energy in the Earth's Core [PDF]

open access: yes, 2006
Key facts: - Geothermal energy comes from the heat in the Earth's core. This heat creates underground reservoirs of steam and hot water, which can be tapped to generate electricity or to heat and cool buildings directly.
