Characteristics of Hydrocarbon Fields in the Croatian Part of the Pannonian Basin

Approximately 104 x 106 m3 of oil from 39 fields, 6.93 x 106 m3 of condensate (11 fields) and 64.92 x 109 m3 of gas (52 fields) were recovered in the Croatian part of the Pannonian basin during 63 years of exploitation (1941–2004). The total production peak was attained in 1980–1989, when exploitation began in 12 new fields. The longest production period is assumed for the largest fields ; for oil it is approximately 55 years, whereas for condensate and gas 46 and 36 years of exploitation are expected, respectively. Water-flooding will probably be the dominant secondary-recovery method for increased production in the future, because CO2 injection requires transport and analysis of fluid interactions.
