Reservoir Geometry Characterisation Using Post Stack Seismic Inversion – Illizi Basin

P12 RESERVOIR GEOMETRY CHARACTERISATION USING POST STACK SEISMIC INVERSION ILLIZI BASIN ALGERIA Abstract 1 D. MEDJAOUD and N. DOUSSAS The Exploration Division Sonatrach Boumerdes 35000 Algeria In the Illizi basin the Cambro-Ordovician play is considered to be one of the important exploration objective not only by the proved reserves but also by prospective trap to be discover. The important Tectonics events occurred in the basin has contributed to model the incised palaeo valley geometry by controlling the material deposition and the associated fault system so it gave different seismic reflectivity response which in some areas it difficult to analyse.
