Abstract
Aquifer thermal energy storage (ATES) is used
for seasonal storage of large quantities of thermal energy.
Due to the increasing demand for sustainable energy, the
number of ATES systems has increased rapidly, which has
raised questions on the effect of ATES systems on their
surroundings as well as their thermal performance. Furthermore,
the increasing density of systems generates concern
regarding thermal interference between the wells of one
system and between neighboring systems. An assessment is
made of (1) the thermal storage performance, and (2) the heat
transport around the wells of an existing ATES system in the
Netherlands. Reconstruction of flow rates and injection and
extraction temperatures from hourly logs of operational data
from 2005 to 2012 show that the average thermal recovery is
82% for cold storage and 68% for heat storage. Subsurface
heat transport is monitored using distributed temperature
sensing. Although the measurements reveal unequal
distribution of flow rate over different parts of the well
screen and preferential flow due to aquifer heterogeneity,
sufficient well spacing has avoided thermal interference.
However, oversizing of well spacing may limit the number
of systems that can
