Sažetak
Abstract-The Belina-1 well is located in the former NC-167 INA-Naftaplin offshore Block. Regionally, the block belongs to the Pelagian platform area in the Sabratah Basin. The geological framework of the study area is the result of complex tectonic, salt movements and sedimentation processes during different geological periods. During drilling and testing gas and oil manifestations were registered within sediments of the Metlaoui Formation and Reineshe Member of the Upper Eocene age. Oils in reservoirs are mature, light and originated from clastics source rocks, regionaly present below economical drilling depths. Oils in reservoirs showed variations in bulk and specific parameters and can be separeted in two types. Gas manifestations of different intensity were registered too. Gases in reservoir are wet, with significant content of higher homologues. Stable carbon and hydrogen isotopic ratios of methane varies in a wide range. According to Schoell (1983) the gas from Metlaoui Formation is classified as migrated, high thermogenic, condensate-associated gas. More negative carbon value shows gas from the Reineche Member. It is a lower maturity gas and can be classified as migrated, thermogenic, petroleum-associated gas. Belina gases also contain inorganic constituents including CO2, N2 and small quantity of H2S. Hydrocarbons from the Belina-1 well show aberrations in maturity and composition indicating different origin, migration pathways and hydrocarbon mixing within reservoirs.
