Abstract
A method for determining the presence of a hydrate history in a fluid involves obtaining a sample of the fluid. The sample is then cooled to determine the amount of cooling required in order to induce hydrate formation. The result is then compared to the amount of cooling required to induce hydrate formation in a sample, which has been heat treated to remove any hydrate history present, before cooling. Also provided are methods for prevention or control of hydrate formation of a fluid in a system. The degree of inhibition of hydrate formation in the fluid is monitored and then the system conditions or fluid composition are adjusted as required. Methods for carrying out monitoring of a fluid liable to form hydrates are also described.
