selected from the group consisting of a drilling a drill in and a completion fluid wherein said water based fluid comprises as an integral component a hydrate suppressing amount of a water soluble organic compound having a molecular weight below about 800 and said fluid has effective rheology and fluid loss control properties application_number US 81424797 A description gas hydrate suppression is needed for several types of fluids used during drilling operations drilling operations typically involve mounting a drill bit on the lower end of a drill pipe or 34 drill stem 34 and rotating the drill bit against the bottom of a hole to penetrate a formation creating a borehole a drilling mud may be circulated down through the drill pipe out the drill bit and back up to the surface through the annulus between the drill pipe and the borehole wall the drilling fluid has a number of purposes including cooling and lubricating the bit carrying the cuttings from the hole to the surface and exerting a hydrostatic pressure against the borehole wall to prevent the flow of fluids from the surrounding formation into the borehole a drilling fluid with a relatively high viscosity at high shear rates can place undesirable mechanical constraints on the drilling equipment and may even damage the reservoir higher viscosity fluids also exert higher pressures outward on the borehole which may cause mechanical damage to the formation and reduce the ability of the well.
