Abstract

A system includes a tubular body, a pressure actuated circulation valve, a first power section, an isolation valve, and a housing. The pressure actuated circulation valve is connected to the tubular body. The first power section is configured to rotate when a fluid is pumped from the pressure actuated circulation valve. The isolation valve is connected to the first power section. The isolation valve comprises a plurality of openings each having a different area and the fluid is exposed to a plurality of different flow path areas. The housing is connected to the isolation valve and comprises a set of springs connected to a piston. The set of springs are configured to pulsate the piston in response to the fluid being pumped through the plurality of different flow path areas and pulsation of the piston creates an axial force acting on the tubular body.
