For controlling the gas hydrate formation process is important for risk management in flow assurance and the development of industrial applications of gas hydrates. The nucleation process, the initiation of the gas hydrate formation process, is a stochastic phenomenon, but its experimental approaches is rather poor. This is likely due to its high sensitivity to various factors, such as the size of the reactor, reaction temperature and pressure conditions, making it difficult to collect data, and due to the requirement for repeated experiments under identical conditions to obtain the quantitative data. The authors have been working on this research, conducting nucleation experiments on various single-gas hydrates and expanding their research into mixed-gas hydrate nucleation. In this paper, we provide an overview of our nucleation experiments on gas hydrates using methane and propane as guests, and summarize the results of experiments on the nucleation of single-gas hydrates and mixed-gas hydrates. We then propose a nucleation process based on the experimental results and discuss future challenges.
