Claim Text:
1. A method of fluidizing a cuttings bed, the method comprising: conveying a downhole assembly in a longitudinal direction within a wellbore, wherein the downhole assembly includes an energy-storing structure that defines at least a charged state and a discharged state, and further wherein the conveying includes generating an axial force within a portion of the downhole assembly; discharging the energy-storing structure by transitioning from the charged state to the discharged state to produce a motive force, wherein the discharging is responsive to the axial force exceeding a threshold axial force; generating a fluidizing stream in immediate proximity to the downhole assembly with the motive force; and emitting the fluidizing stream from the downhole assembly to fluidize a portion of the cuttings bed, at least a portion of the emitted fluidizing stream oriented parallel to the generated axial force.
