Abstract:
1. A method, the method comprising: pumping fluid to a downhole tool to rotate and orbit a first and second sleeve around a central element to advance the downhole tool into a wellbore, the downhole tool comprising: a rotor profile disposed on the central element; the first sleeve rotatably and orbitally disposed around the central element, the first sleeve rotates around the central element responsive to fluid flowing through the downhole tool and has a stator profile disposed on the inside thereof to cooperate with the rotor profile to force the sleeve to rotate and orbit around the central element as fluid flows through the downhole tool; the second sleeve rotatably and orbitally disposed around the central element, the second sleeve has a stator profile disposed on the inside thereof to cooperate with the rotor profile to force the second sleeve to rotate and orbit around the central element as fluid flows through the downhole tool; a connecting component disposed between the first sleeve and the second sleeve; and an outlet disposed in the central element to permit fluid to flow from a passageway disposed through the central element to an annulus area disposed between the central element and the sleeves.
