@Gholamreza, To provide a scientific response to your query, you would need to take the following into account: Geological Surveys: In order to find potential oil and gas formations, has the area undergone any seismic or geological exploration? Closeness to Known Gas and Oil Fields: Although there aren't many large oil and gas deposits in eastern Iran, other areas and nations may have information regarding geological formations. Sedimentary Basins: These areas are frequently where oil and gas can be found. Has the area surrounding Nehbandan been examined to determine whether these basins exist?
