9. A system for cleaning debris from a wellbore, the system comprising:
a workstring assembly comprising:
an upper tubular portion defining an upper exterior housing of the workstring assembly;
a lower tubular portion defining a lower exterior housing of the workstring assemlby;
a fluid moving tool coupled between the upper and lower tubular portions, the fluid moving tool including a rotational portion and a stationary portion at least partially surrounding the rotational portion, wherein rotation of the upper tubular portion relative to the stationary portion rotates the rotational portion relative to the stationary portion: and
a rotational power source located at a surface of the wellbore, wherein the upper tubular portion is coupled to the rotational power source such that the rotational power source can provide rotational energy to rotate the upper tubular portion and the rotational portion of the fluid moving tool, wherein the rotational power source is one of a power swivel, a top drive drilling rig, and a rotary,
wherein the rotational portion and the stationary portion are shaped and configured such that, when the lower tubular portion is at least partially disposed in well fluid, rotation of the upper tubular portion relative to the stationary portion rotates the rotational portion relative to the stationary portion and causes movement of the well fluid such that well fluid flows into the bore of the lower tubular portion, thereby carrying debris from the wellbore into the bore of the lower tubular portion.
