Abstract

The aim of this study is to estimate reservoir temperature of the Continental intercalaire aquifer (CI), for possible geothermal exploitation. As CI depth increases, water increases its temperature, under the effect of geothermal gradient.The approach is based on sampling and analysis of water physico-chemical parameters, then hydrochemistry and geothermometry were performed.The results show that CI waters have got a high mineralization, high electrical conductivity values, discharge temperatures of 43 to 52°C and a SO4-Cl-Na-Ca water type that refers to the evaporate albian aquifer. After that, different geothermometers were used that allowed the estimation of the reservoir temperatures (60-80°C).
