Systems and Methods to Inhibit Packoff Formation During Drilling Assembly Removal from a Wellbore

A method of removing a drilling assembly from a wellbore, wherein the drilling assembly includes a transition region between a first section including a first cross-sectional area and a second section including a second cross-sectional area, wherein the first cross-sectional area is less than the second cross-sectional area, wherein the first section is farther from a terminal end of the drilling assembly than the second section, and further wherein the drilling assembly includes a fluid conduit configured to transmit a drilling fluid stream, the method comprising:

• withdrawing at least a portion of the drilling assembly from the wellbore;
• detecting a variable associated with packoff within the wellbore;
• and
• providing a fluidizing stream to a portion of a cuttings bed proximal the transition region, wherein the fluidizing stream includes a portion of the drilling fluid stream, and further wherein the providing includes selectively providing the fluidizing stream based at least in part on the variable associated with packoff.

A drilling assembly configured to drill a wellbore, the drilling assembly comprising:

• a first section having a first cross-sectional area;
• a second section having a second cross-sectional area, wherein the first cross-sectional area is less than the second cross-sectional area, and further wherein the first section is farther from a terminal end of the drilling assembly than the second section;
• a transition region between the first section and the second section;
• a fluidizing assembly configured to fluidize a portion of a cuttings bed proximal the transition region;
• and
• a fluid drive assembly configured to receive a wellbore fluid stream from within the wellbore and to provide the wellbore fluid stream to the fluidizing assembly, wherein the fluidizing assembly is configured to provide the wellbore fluid stream to the portion of the cuttings bed as a fluidizing stream.
