Abstract
A slow rotating mole apparatus for use in hydrablasting wellbores and pipelines. The apparatus generally consists of a motor section with a rotor rotatable in response to fluid flow through the motor section, a speed reducer section connected to the motor section such that an output speed of the speed reducer section is less than an output speed of the rotor, and a jetting section attached to the speed reducer section and rotated thereby at the speed reducer output speed. The speed reducer section and jetting section define a flow passage therethrough in communication with jetting ports in the jetting section so that the fluid pumped through the apparatus is jetted therefrom. The speed reducer section may include one or more gear reductions to achieve the desired rotational speed of the jetting section.
