Test drilling for ATES
Where a TRT is essential to make a detailed design for a BTES system, one can also consider performing a test drilling for an Aquifer Thermal Energy Storage (ATES) system. A test drilling for ATES also consists of a borehole, but in this case equiped with a filter rack in the desired aquifer. Afterwards, we insert a pump in this borehole and let it pump continuously for at least 1 day. At the same time, we measure the flow rate and the reduction of the groundwater level in the borehole.
Test drilling provides clarity
A test borehole with a flow test is recommended when there is strong uncertainty about the geothermal performance of the aquifer.
The test borehole can provide clarity about the exact thickness of the aquifer, the transmissivity, the correct aquifer temperature ...
