چکیده

fault detection is one of most important steps in seismic interpretation either in exploration or in development phase . There are a variety of seismic attributes enhancing fault visualization and detection already used by interpreters . The ant -tracking attribute is improved by schlumberger and is commercially available in petrel soft ware.it emulates the behavior of ant colonies in nature and how they use pheromones to mark their paths in order to optimize the search for food. what we have done is working on ant -tracking attribute which is a very powerful attribute in fault detection that can give us fault patches both automatically and manually . in this study the general workflow to get an acceptable and clear result showing exact trend and path of faults have been provided which require considerable amount of manipulation on related parameters, each of which have been discussed separately. automatic extraction of fault surfaces also has been done form ant-tracking attribute cube which not only shows very good match to those have been manually interpreted but also some minor faults which can not be detercted easily by routine interpretation, are visible on ant -tracking attribute cube.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
