Abstract:
A method of inhibiting gas hydrate formation in downhole fluids, including providing a downhole fluid and mixing the downhole fluid with an aqueous gas thermodynamic hydrate inhibitor formulation to form a downhole fluid mixture. A concentration of lithium chloride in the downhole fluid mixture is at least about 1 wt % and a density of the downhole fluid mixture is in a range of about 1.08 to 1.3 gm/cm3 at a downhole temperature of about 50° F. or less and a downhole differential pressure of about 500 psi or higher. An aqueous gas thermodynamic hydrate inhibitor formulation and oil and gas well drilling system including such a formulation are also disclosed.
