The Sarvak and Ilam Formations in the Zagros sedimentary basin are known as reservoir ROCKs. Over 50 hydrocarbon fields are in the Zagros basin at the Sarvak and Ilam hydrocarbon Formations, and the Fars region is about 5%. This research identifies areas with hydrocarbon potential of the Formation of Sarvak and Ilam at Fars area parameters such as Formations outcrop, main faults, isopach maps, and volume of upper Formations sediments extracted from geology map of the area. With fuzzification of the layers and overlapping them with each other, the areas with high hydrocarbon potential were identified in the Ilam and Sarvak Formations. Regarding exploration potential in the Sarvak and Ilam Formations, the Fars region was identified as an area with poor hydrocarbon potential. Somehow 75.25% of the Fars area has inferior hydrocarbon potential, 18.5% has standard hydrocarbon potential, and only 6.25% has high hydrocarbons potential for exploration at the Sarvak and Ilam Formations. While considering to fault effect and their outcrops, the percent of areas with high hydrocarbon potential decreased to 3.6%. Also, Fuzzy logic as a multi-value logic from masters knowledge and designed inference network could identify all fields with hydrocarbons potential in the Sarvak and Ilam Formations in the Fars area and recognize those areas as a high hydrocarbons potential.
