Patent ID: 8607871

Claim:
A jetting tool to clean interior cavities of a wellhead having a landing ring therein with a landing surface and a restricted diameter throughbore, and to clean interior cavities of one of a hydraulic ram and an annular blowout preventer connected above the wellhead and having an enlarged diameter throughbore that is greater than the restricted diameter throughbore of the landing ring of the wellhead, the jetting tool comprising: a unitary body having a central throughbore and a plurality of radially outward jets each extending from the central throughbore of the body to one of an upper large diameter outer surface of the jetting tool and a lower small diameter outer surface of the jetting tool, such that the lower small diameter outer surface of the jetting tool is positioned within the restricted diameter throughbore of the landing ring and the upper large diameter outer surface of the jetting tool is positioned within the enlarged diameter throughbore of the one of a hydraulic ram and an annular blowout preventer and a plurality of circumferentially spaced and tapered landing shoulders on the body intermediate the upper large diameter outer surface of the tool and the lower small diameter outer surface of the jetting tool, the tapered landing shoulders sized and angled to engage corresponding supports of the landing surface of the landing ring of the wellhead; wherein fluid pumped into the jetting tool exits the jetting tool through the plurality of radially outward jets to impinge upon and to thereby clean debris from interior cavities along the enlarged diameter throughbore and the landing ring.
