The Reykir low-temperature geothermal area at Reykjabraut is on the edge of the Vatnsdalur extinct central volcano. Eight deep geothermal wells have been drilled in the area, with a depth of 234 to 1676 m. Wells RR-05 and RR-12 are the major production wells. Based on the consideration of fluid and mineral compositions, geothermometers, mineral-solution equilibrium, mixing, isotopes, and water-rock interaction, this paper mainly describes the chemical characteristics of the thermal fluids, their origins, and the recharge and discharge of fluids. Finally, the process of water-rock interaction was modelled with PHREEQC. Some of the results were compared to the nearby Laugarbakki field in order to discuss different formation conditions of geothermal fluids. |
