oa Sedimentary Characters Changes in Fractured Micritic Reservoirs - Example of the Abiod-Bou Dabbous Formations in Northern Tunisia

Fractured micritic reservoir rocks constitute in Tunisia additional hydrocarbon targets since the discovery of oil in some fields such as in Sidi el Kilani, Zinia, Belli, (Ben Ferjani et al. 1990) El Menzah etc.. In Tunisia, the main developed fractured micritic carbonates are constituted of the Campanian Abiod Formation (Burollet, 1956; Negra et al, 1994; Negra, 1998) and the Ypresian Bou Dabbous Formation (Fournié, 1978; Loocks et al, 1996).
