A method that allows the effect of the fluid shear rate on the induction time of gas hydrate formation to be characterized was developed and applied to CO 2 ‐THF hydrate formation. The investigation of the effect of the application of a constant shear rate (50 to 300 s −1 ) to the liquid phase from which the hydrates are formed revealed that the mean induction time decreases significantly as the applied shear rate increases. This could primarily be attributed to a decrease in the time required for stable gas hydrate nuclei to be generated and to grow to a macroscopically detectable size. The induction time could also be significantly reduced by the application of a high shear rate (900 s −1 ) to the liquid phase for a relatively short, defined period of time.
