ABSTRACT:
A fluid injection apparatus includes a portable base frame having a pumping mechanism and fluid container mounted thereon. A conduit connects the pumping mechanism to a spacer flange which can be interconnected between a blowout preventer and a choke manifold so that fluid can be readily injected into these two types of equipment. The apparatus and its interconnection between the blowout preventer and choke manifold provide a technique by which accumulated solid deposits within the blowout preventer can be blown back toward the well to prevent their passage into the choke manifold, thereby preventing blockage of the choke manifold. The apparatus and method of the present invention also permit fluids to be injected into the blowout preventer and choke manifold for such purposes as conducting pressure tests and for preventing freezing of the components of the blowout preventer and choke manifold.
