Abstract:
A method for determining gas hydrate formation conditions in a well fluid, comprising the following stages:taking a fluid sample, placing this sample in a calorimetry cell, performing on this sample a reference thermogram in a temperature range between T1 and T2, performing on the same sample a second thermogram in the same range and under a pressure Ph of a hydrocarbon gas, T1 being a temperature low enough to obtain the formation of hydrocarbon gas hydrates in the sample at a gas pressure Ph, T2 being high enough to obtain hydrate dissociation, identifying a peak in the second thermogram corresponding to the hydrocarbon gas hydrates dissociation zone and deducing therefrom a hydrocarbon gas hydrates dissociation temperature, determining the hydrocarbon gas hydrate formation conditions for the fluid considered.
