Abstract
Summary We performed a laboratory experiment that consists of monitoring the effect of temperature variations of ground water that is stored in partially saturated sands. Warm water is injected through an injection well to recreate the actual conditions of a geothermal well. The monitoring is carried out utilizing the acoustic (DAS) and resistivity (ERT) methods. We deployed both DAS and ERT methods utilizing a cross-well set-up. The measurements were performed in a time-lapse fashion with water injected at low and high temperatures. The inverted P–wave velocities and resistivities displayed noticeable changes while increasing the temperature with time. The results show that DAS and ERT can be potentially utilized for monitoring temperature changes in field scale geothermal wells.
