     recent seismic surveys detected thick layer of free gas underlying hydrate bearing sediments through observation of direct seismic attributes, in the area of 27,000 km2, in the makran offshore area of iran. this potential energy source should be evaluated concerning production potential which is subject to very large uncertainties. whereas, a meaningful development plan incorporating the associated uncertainty calls for large number of simulation runs, analytical models are useful tools for fast engineering calculations conducted at the beginning of the life of reservoirs. in this paper, we investigate the class in which gas hydrates on the continental slope off iran belong, as well as we propose the best production strategy which is well suited to the conditions of gas hydrates within the study area to maximize production. then, we use gerami and pooladi-darvish’s analytical model along with monte carlo simulation to capture the effect of uncertainty in hydrate and reservoir parameters on the performance of a prospect, located on the continental slope off iran. the importance of employing analytical models for quantification of uncertainty, especially in the initial stages of development of gas hydrate reservoirs; also, is discussed. the results of study indicate considerable contribution of hydrates in total produced gas, as well as high hydrate recovery. it reveals a significant economic advantage which guarantees gas production from gas hydrates in the iranian part of the oman sea using conventional technology.
