Abstract: Devices, systems and methods for cutting openings in a wellbore tubular by a slot cutting assembly having an anchoring system and a slot cutting tool. The anchoring assembly anchors the slot cutting assembly within the wellbore. The slot cutting tool has an extendable cutting blade that is pushed into the wellbore tubular to cut an opening through the tubular. The slot cutting tool may have an extendable stabilizing arm to stabilize and assist with cutting by the blade. The slot cutting assembly may have azimuth and depth sensors to assist with positioning the tool at a desired position downhole. A surface system may be used to control the position of the slot cutting assembly downhole.

Abstract: 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.
