Abstract
The present invention is directed to a method for preventing gas hydrates formation in BOP fluids in deep water well operations that includes the step of adding at least 28% glycol by volume to a BOP fluid, whereby the hydrate phase equilibrium line shifts to the point where the operating conditions will not form a hydrate.
