520	3		_aGas hydrates still continue to be a problem for the oil and gas industry, due to the significant potential of plugging in both onshore and offshore oil and gas pipeline. In deepwater offshore oil fields, the risk of gas hydrate blockages in pipeline and offshore facilities is higher due to the intensified high pressure and low temperature conditions. Therefore, gas hydrates are the main issue for flow assurance, which needs to be addressed to ensure the continuous flow of fluid in oil and gas flowline and facilities. Gas hydrate formation is also another significant problem in deepwater oil and gas production, from a safety standpoint. Low temperature (from 0℃ to 12℃) with high pressures (435 psia to 1450 psia), are the ideal conditions for gas hydrate formation, conducive to crystalline structure growth, along with elevated concentrations of the gas stream and the presence of water (H2O). The energy and engineering industry need to control the production of hydrates and blockages in oil and gas pipelines. Gas hydrate blockage in pipelines can be prevented using a variety of techniques, including chemical additive injection. This research examines how Methanol (MeOH) and Polyvinylpyrrolidone (PVP) effect the formation of gas hydrates. The objective of this study is to investigate the synergistic effect of methanol (MeOH) as thermodynamic hydrates inhibitor (THI) and Poly-Vinyl Pyrrolidone (PVP) as kinetic hydrate inhibitor (KHI) on the gas hydrates formation, and to use tetrahydrofuran hydrates (THF) as a medium to assess the effect of Methanol and PVP as thermodynamic and kinetic inhibitor. The experiment is conducted by preparing the hydrates by ex-situ. The hydrates former that used in this experiment is mixed with deionized water in a 1:17 mole ratio. Methanol is added into the tetrahydrofuran hydrate solution in different concentration, which is 10 vol%, 20 vol%, and 30 vol%, and PVP added following the concentration of 0.0005 wt.% and 0.001 wt.%. This method used to observe the nucleation time of tetrahydrofuran hydrates. The analysis results show that the higher the concentration of THI, the slower the formation of tetrahydrofuran hydrates to form. The findings of this study provide important knowledge into how Methanol and PVP influence the formation of gas hydrates. This demonstrates the potential for controlling and improving hydrate-related technologies for various industrial applications, including energy storage, and the flow assurance of pipeline.
