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.

Debris collection and removal from a wellbore

Systems and methods presented herein provide for cutting in a borehole or casing. A cutting device can include a first arm having a cutting blade, wherein the cutting blade has side cutting teeth and an axis of rotation that is substantially at a right angle with respect to an axis of the tool body. The cutting device can also include a second arm with a bumper. The first and second arms articulate away from the elongate body in different directions to reduce vibrations while cutting. A control device can automate the cut based on hydraulic pressure measurements. Additionally, the cutting device can also be extended or rotated on a rotary index. The cutting device can rotate around a J slot, in an example.
