Today with regard to the population growth and industry in the world, the lack of energy resources and global warming of the earth because of using fossil, the world to search for new and renewable resources and energy , which have the least environmental damages to the earth .(Kyoto protocol) Throgh new and inexpensive energy resources, is Erath thermic (Geothermal) energy. In our country, because of existing places with high thermal gradient, some regions denoted as susceptible fields to extract this type of energy. One of those fields, id south-eastern regions of Meshkinshahr- hillslides of Sabalan Mt.- in Ardebil province. In concern with geothermal value of the region, several exploration methods has used as regional and formal steps. One of them is Magnetotelluric mehod as a geophysical exploration, which is the main topic of this project along naturalizing earth scinces and technics, the project is concerned with magnetotelluric three dimensional forward modeling , problem and strategies for performance and optimization of such modeling. First, a curt introduction about geothermals , their exolrating methods and discussion about importance of magnetotelluric and among other methods have presented. then magnetotelluric bases will exhibited voluminously, and its technics of forward modeling with their problems and advantages. Next , using some of MT data which surveyed from Sabalan geothermal fields, a simple model will presented to justificate the data. Finally , with scrutiny of the results, some proposes will be offedred to optimizing the operations to exibit a model for 3D inverse modeling
