The Mačva hydrogeothermal system was discovered in 1982. when a large conductive geothermal anomaly was discovered in the Neogene sediments in Dublje, i.e. in the central part of Mačva. At that time, hydrogeothermal research began, but it has not yet been completed. Their results show that the low-temperature convective hydrogeothermal system “Mačva” is part of a large regional same system, which extends below Mačva, Semberija and Srem on about 2000 km2. The results obtained so far are very interesting.

Beneath the Neogene sediments is a karst reservoir in Triassic limestones from which intensive exploitation of geothermal energy is possible for heating settlements, food production and for use in industry. Above the reservoir in the central part of Mačva, the most intense conductive geothermal anomaly in the entire Pannonian Basin was discovered, because thermal water with a temperature of 75C was discovered in a well at a depth of 412 m. That is why Mačva represents the Yugoslav and Serbian “Red Spot”, like the Pannonian Basin in Europe. The results of preliminary tests performed in exploratory wells, as well as the results obtained by hydrogeothermal modeling show that the exploitation of geothermal energy with a thermal power of at least 150 MW is possible in Bogatić, but its use has not yet begun.
