Abstarct: South of sedimentary structures are important in Iran for accumulation of Hydrocarbon resources as a result of different methods used to detect them. According to the vital importance of groundwater resources in the economy, low cost, fast and efficient exploration methods has found a special place to advance the exploration goals. To identify hydrocarbon resources and Oil Trap such anticline, salt dome and mud volcanoes only surface information may not be reliable. Therefore, indirect methods such as geophysics to identify such structures are used. Geophysical methods in exploration of hydrocarbon resources are used and have wide experience, seismic and gravity methods, which along with other methods such as magnetometer, magneto telluric and electromagnetic can identify subsurface geological structures. However, these methods are often unable to provide a comprehensive model alone. According to achieve a unique model, we should use several methods simultaneously that all of these methods used the physical characteristics of the environment As such parts of the method do not provide a good answer; other methods could complement the results. To achieve a unique model of several methods used so that if a method is not suitable answer another method can be completed it. Researchers have long attention to the relationship between the different physical characteristics that positive results have been obtained, the purpose of this study was to investigate and identify mud volcanoes so two methods were used simultaneously. Due to the inability of seismic methods in identifying subsurface structures, the relation between speed and density is used after preparation of the Bougure anomaly, the density and velocity was prepared according to Gardner equation. The results of modeling of the velocity distribution on the basis of gravity data indicate that the detachment of the subsurface structures is acceptable. Velocities derived from gravity data were compared with Velocities derived from seismic data as if they confirm each other. According to lost cost of gravity method, useful information can be obtained with this method
