Quest for “Green Energy” has accelerated the exploration activities around the world. Unconventional resources are treated as potential energy source of the century, gas hydrate having a large amount of methane trapped in form of hydrates are widely available in Arctic region and Oceanic sediments. Efforts are required to understand the potential of these unconventional resource and ways of exploiting it in an economical way and with limited footprint. Makogon (1981), showed the capability of chemical enhancers by increase in gas production at the Messoyakha field. Sloan (1992) has also suggested the use of enhancers (inhibitors) in gas production. Our work will deal with series of experiments to determine the effect of polymer (Polyethylene Glycol, PEG) at varying molecular weight and constant mass fraction to study the effect of inhibition on gas hydrate. Through this it has been observed that the lower molecular weight of PEG (Polyethylene Glycol) will show larger inhibition than PEG of higher molecular weight (PEG 200 > PEG 400 > PEG 600). Also that polymer flooding into hydrate reservoir increases the decomposition rate over the pressure drive mechanism.
