Abstract:
1. An apparatus for deflecting a tubular having a tubular wall, comprising: an aperture in the tubular wall, and a nozzle mounted within the aperture in the tubular wall and being an integral part of the tubular wall, the nozzle for defining a converging flow path such that fluid passing through the converging flow path has a velocity that increases as the fluid passes through the converging flow path, causing the static pressure exerted by the fluid to decrease, the velocity to increase and the ram pressure to increase, the ram pressure increasing to a maximum pressure as the fluid exits the nozzle, wherein fluid moving through the tubular is directed through said nozzle, and wherein said fluid moving through said nozzle creates a jet flow with a maximum ram pressure which deflects the tubular in a direction substantially opposite the direction of the fluid flow through said nozzle.
