Gas hydrate has been one the major flow assurance challenges in natural gas production, storage and delivery to the end users. The aim of this research was to conduct an experimental investigation of a locally formulated chemical for the inhibition of gas hydrates. The research entails identifying an adequate local inhibitor using an n-vinyl caprolactam (N-VCAP) as additives with pressure/temperature analysis to assess the effectiveness of the formulated local inhibitor. In this study, experiments were conducted using a mini loop with a diameter of 0.5inch and total length of 12 m. In the experiments, local materials were used to create “Sample A” a biodegradable and water-soluble hydrate inhibitor. Experiments were further carried out to establish that the local inhibitor has a high inhibitory potential as compared to traditional inhibitors, N-Vinylcaprolactam (N-VCap). Different weight percentages of these inhibitors tested were 0.01wt%, 0.02wt%, 0.03wt%, 0.04wt%, 0.05wt%, 0.06wt%, and 0.07wt%. Plots of pressure, temperature and time of the formulated and conventional inhibitors were made and the results obtained were analyzed. 0.01wt%, 0.02wt% 0.04wt%, 0.05wt%, 0.06wt%, and 0.07wt% of Sample A clearly showed better inhibitory performance than the conventional ones. Sample A is environmentally friendly, biodegradable, affordable, efficient, and water soluble. As a result, it has been approved for field testing.
