The Upper Devonian-Carboniferous reservoirs correspond to new hydrocarbon plays in south western Algeria, highlighted during the recent Repsol s exploration drilling campaign (2003)(2004)(2005)(2006)(2007). Strunian and Tournaisian sandstone units produced potential gas flows from several wells essentially located in the western trend of Reggane basin. They correspond to prograding fluvial-deltaic cycles from South to North, alternating with transgressive events, prior to the global marine

Reservoir characterization is the main objective of this integrated study using chronostratigraphy and 3D modelling. Biostratigraphy and field work will complete the data base in this wide area. In terms of reservoir properties, main regional quality variations seem to be related to facies changes and diagenesis effects.
