title of the reference :  New potential hydrocarbon source-rocks in the Lower Eocene Metlaoui Formation (Central-Northern Tunisia, Northern Africa).
Publication Date: 2007
Author : Montacer Mabrouk
Catalogue type : Livre
Catalogue reference : Vol.5, N°3 Geologica Acta Vol.5, N°3 New potential hydrocarbon source-rocks in the Lower Eocene Metlaoui Formation (Central-Northern Tunisia, Northern Africa). Significant quantities of organic matter accumulated and were preserved in central-northern Tunisia during the Ypresian (Early Eocene). The organic geochemical characterization of the organic rich facies in the Ypresian Metlaoui Formation (Ousselat and Es-Sfeia sections) shows their significant potential as source rocks and increases interest in the Central- Northern Tunisia oil play. The TOC content in these rocks ranges from 0,09 to 3,71% suggesting their petroleum potential. These values and the predominance of the hetero compounds (NSO: 2-95%) point to low organic matter maturation. The diverse maturity levels reported for these organic-rich rocks never reached the conventional oil window peak stage and resulted from their different locations within the basin. The fluctuation of the pristane/phytane ratio (0,97-2,53) records changes of the basin redox conditions, which mainly evolved around the sub-oxic range. bibliogr. matière organique ; pyrolyse ; analyse chimique ; hydrocarbure ; roche mère hydrocarbure ; Yprésien ; Formation Metlaoui ; Tunisie ; Tunisie Centrale ; J.
