“…Focused fluid flow at the sediment-water interface has been studied extensively giving insights into the basin "plumbing" system, especially in regard to hydrocarbon migration dynamics (Heggland, 1998;, and also on its impact on the bio-, hydro-, and atmosphere (Hovland et al, 2005;Judd and Hovland, 2007), and as a potential geohazard (e.g. Ligtenberg and Connolly, 2003;Judd and Hovland, 2007;Cathles et al, 2010).

“…A comparison between detected fractures and gas chimney indicates the open and closed fractures, which are shown in Figure 8 (Ligtenberg, 2003;Ligtenberg and Connolly, 2003). Vertical fractures, which are able to transport hydrocarbon, were detected using gas chimney technology.…”

“…Determination of the hydrocarbon migration pattern, on the other hand, plays a key role in petroleum exploration (Ligtenberg, 2003;Ligtenberg and Connolly, 2003). Finding fractures' pathways helps reservoir engineers to simulate the petroleum reservoirs accurately and recognize the best locations for well drilling.…”

Faults/fractures role in oil exploration is invaluable. In this study, all determinative seismic attributes (with different insight to the data) were applied. To achieve an image including the results of all attributes, the geographical information system was used to integrate the resultant images of different attributes. To do this, the Laplacian filter was applied to sharpen the linear structures on computed attributes images. Then, a principal component analysis was applied to increase the clarity of fracture. Finally, comparing the result of the author's study with the output of neural network analysis proves that each method has its own advantages and their integration will fulfill the research objective.

Recognition of hydrocarbon migration is so vital for petroleum exploration. Developing intelligent systems (artificial neural network) enable experts to achieve more details from seismic data. Although detection of migration direction using seismic data is difficult, Chimney-cube analysis overcomes this problem. The authors used several filters, seismic attributes, neural network (supervised and unsupervised), and interpreters' viewpoints. In supervised method artificial and human intelligence cover their limitations and in unsupervised method the authors eliminate the experts' views. Chimney recognizes the migration direction and locates the spill points, mud volcanoes, gas seepages, sealing, and nonsealing faults and finally the origin of hydrocarbon.
