P32 FIELD-SCALE CO2 GAS FLOODING IN SANDSTONE AND LIMESTONE RESERVOIRS Abstract 1 CO2 gas flooding in Hungary has achieved a wide range of field application based on natural Carbon-Dioxide resources. The oldest field scale application has been applied in the west part of Hungary in sandstone reservoirs of Budafa and Lovászi fields while in fractured karstic limestone and dolomite reservoirs of Nagylengyel field. After some pilot tests the first field-scale application started in the sandstone formations of Budafa field in 1972. The produced crude is of an intermediate- paraffin character its average density is 820 kg/m 3 (41 Degrees API).
