Abstarct: Stratigraphic traps will be formed by carbonate and sandstone deposition through bottom of river and sea basins. Is is supposed that there are typical stratigraphic traps, as river channels, for instance, related to Cretaceous’s period fromed by carbonate and sandstone deposition. However, yet almost all of the traps found in the southwestern part of the Dezful embayment (the Abadan plain), Azadegan oil field, are in structural type. To explore possible stratigraphic traps in the mentioned area, 3D seismic reflection data was interpreted by seismic attributes. Though there are different geometries of traps, they are often observed syncline. Seismic attributes is a method for detecting geological objects, fractures or any turbulence and subsurface geological even. Some of these attributes were classified to define the traps, such as, Amplitude Contrast, Frequency, Curvature and Variance. Each of these attributes would analyzes the subsurface turbulences by applying the desired processing to the seismic trace for oil fields identification and examination to reach the research object. In this thesis, according to the results obtained from each attribute, for improving the image resolution and achieve desired result of the selected method, stratigraphic traps interpreted within paired fusion of attributes by a method in MATLAB software called "Imfuse", and the range high resolution is displayed for exploitation.
