Abstract

Systems and methods to inhibit packoff events during downhole assembly motion within a wellbore comprise a downhole assembly that includes an energy-storing structure that defines a charged state and a discharged state and is configured to generate a motive force upon transitioning from the charged state to the discharged state. A fluidizing stream is generated with the motive force from the energy-storing structure which emits the fluidizing stream from the downhole assembly to fluidize a portion of a cuttings bed that may be within the wellbore and proximal to the downhole assembly.
