This study examines the effects Mixture of SDBS\SDS (1\1wt.%) for increasing stability and gas content of natural gas hydrates. For comparison, formation of natural gas hydrate (NGH) from pure water with SDBS\SDS\water system was studied. A high–pressure reactor in a laboratory–scale is used for measureing hydrate formation rate and stability. By the present of SDBS\SDS, the hydrate formation rate increased effectively. The results show that SDBS\SDS decrease the induction time (13.6%) and increase moles of trapped gas in gas hydrate crystals (38.1%). Hydrate stability tests were run at –10°C but SDBS\SDS could not stabilize the hydrate for long time<\div>

Iran''s proved natural gas reserves are the world''s second largest reserves. Mainly, because of different climate changes and different reservoirs characterizations, studying the behavior of producing outcome fluids and their transportation, is of major interest. One of the main problems occur in the gas reservoirs is related to the hydrate formation while producing from a well, either in production strings or lines (before and after choke). Effective parameters which lead to hydrate formations are: high pressure in strings, low wellhead temperature together with water presence; and hence, the high possibility of having this phenomenon in the reservoirs is quite obvious for the gas wells. Hydrate formation in production lines and facilities will also lead to different impediments such as: complete or partial closure in production lines and heat exchangers, erosion of the equipment, pressure reduction, and etc. In this research, the conditions of hydrate formation, using the experimental data from one the Iranian sour gas field that is helpful to determine the safe\unsafe zones by P–T curves, are thoroughly investigated. In addition, the results will be compared to the other presented correlations available in the literature.
