In May 2021 our company had been commissioned to carry out geophysical measurements in the village of Kányád in Szeklerland for drinking water research. Together with the geologists from Total Proiect in Odorheiu Secuiesc and GeoSearch in Florești, were reviewed the geological maps and decided to look for layers with higher porosity, far from the location of the barren or saline boreholes. Using electrical resistivity tomography (ERT) measurements, we were able to delineate Pannonian-age gravel and sand layers and select drilling locations. 

The work was fruitfull, the Petecu drilling was completed first with a yield of 4 m3/hour, followed by the Daia drilling with a yield of 5 m3/hour.

For the last occasion, the Obrănești borehole was drilled, an artesian well with a yield of 5 m3/hour.
