Debris collection and removal from a wellbore

Abstract

Systems and methods are disclosed herein for improved debris collection within a wellbore. An example method can include inserting a tool into a wellbore, where the tool includes an input shaft, an auger shaft, and a collection chamber. The input shaft can be rotated in a first direction, causing rotation of the auger shaft. The rotation of the auger shaft conveys debris into the collection chamber. The input shaft can also be rotated in a second direction, which causes the auger shaft to retract within the collection chamber. The retraction of the auger shaft within the collection chamber prevents the debris from escaping the collection chamber. The tool can then be removed from the wellbore while preventing the collected debris from escaping the collection chamber.
