Abstract
A well system includes a work string extendable into a wellbore, and a pump that pumps a fluid into an annulus defined between the work string and the wellbore. A flow-activated motor is coupled to the work string and has a housing that receives the fluid pumped into the annulus. The flow-activated motor further includes a driveshaft rotatably positioned within the housing and a plurality of rotor vanes coupled to the driveshaft, wherein the driveshaft rotates as the fluid flows through the housing and impinges on the plurality of rotor vanes. A rotating agitator tool is coupled to the driveshaft such that rotation of the driveshaft correspondingly rotates the rotating agitator tool. The rotating agitator tool engages and loosens debris in the wellbore while rotating, and the debris is entrained in the fluid and flows through the flow-activated motor and subsequently to a surface location for processing.
