Hydrate former system composed of methane-propane-water was studied at different experimental conditions using a PVT cell through isochoric method. This work evaluates the effects of some factors on hydrate formation, such as sub-cooling degree, mixing, multiple cycles and initial gas phase composition. These factors were verified to affect the rate of hydrate formation, the type and proportions of hydrate structures and the thermodynamic behavior during dissociation. The main results show preferential formation of structure I when mixing the system while structure II is favored at low sub-cooling and multiple cycles. Finally, the gas phase composition determines the type of structure which prevails during hydrate formation. Thus, these factors must be considered when comparing or designing experiments analysis using PVT cells
