Focused on the problem that the conventional seismic inversion cannot effectively identify the reservoirs and evaluate the property of hydrocarbon-bearing of the terrigenous barrier reservoirs in barrier coast environment, an analytical prediction method is proposed with a case study of the Devonian of block B in Oued Mya Basin, Algeria. That is within the minimum sequence stratigraphic unit, with the controlling of isochronous framework of flood surfaces, using the stochastic simulation to predict the distribution of sand bodies, the lithologic indication simulation to predict the lateral distribution of oil in reservoir, combining reservoir geophysical, seismic attribute, and deposition analysis and other comprehensive reservoir prediction technology to take effective reservoir prediction of terrigenous barrier bar. The results show that the method can effectively predict the spatial distribution of terrigenous barrier reservoirs in the block B, and the actual drilling is in good agreement with the previous prediction. So, this study and the proposed method successfully explored a technical series for evaluating the effective reservoirs of terrigenous barrier bar.
