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

A mechanical service tool that may include one or more anchors, a cutter, a communication and control system, and one or more sensors, as well as methods for operating the mechanical service tool, are provided. The one or more anchors may extend radially from the mechanical service tool and the cutter may move relative to the mechanical service tool. The cutter may include a drilling bit. The communication and control system may obtain remote commands that control the cutter, the one or more anchors, or both. The one or more sensors may detect operational conditions of the mechanical service tool and may be operatively coupled to the communication and control system.

Systems and methods for downhole service tools

A downhole grabber system includes a lower tool assembly. The lower tool assembly includes a lower housing, a jaw assembly, and a plunger. The jaw assembly includes a first jaw pivotally coupled to the lower housing. The first jaw includes a first slot. The jaw assembly also includes a second jaw pivotally coupled to the lower housing. The second jaw includes a second slot. The plunger includes a protrusion that intersects the first and second slots throughout at least a portion of a stroke of the plunger.

Downhole grabber systems and methods

A method for milling and removing debris in a wellbore, comprising: moving a collecting while milling (CWM) tool downhole into the wellbore; and conducting a first operation with the CWM tool, wherein the first operation comprises: a first cycle including operating a motor of the CWM tool at a first torque and a first speed, wherein the first operation includes milling an obstruction in a wellbore; and a second cycle including operating the motor of the CWM tool at a second torque and second speed to power a centrifugal pump to circulate wellbore fluid through a bailer of the CWM tool to collect debris, wherein the first torque is greater than the second torque and the second speed is greater than the first speed.

Real time automated control method for wireline downhole debris collecting while milling operation

A system for performing a mechanical operation on a wireline is described including: a motor; a gear train coupled to the motor, the gear train including a first and a second rotational output, the first and second rotational outputs having different rotational speeds relative to each other; a fluid pump coupled to both the first and second rotational outputs, the fluid pump including: a pump housing coupled to the first rotational output, and a pump input coupled to the second rotational output; and a milling bailer coupled to the housing of the fluid pump and configured to rotate with the fluid pump housing, the milling bailer including: a bailer portion shaped to intake fluid and allow the fluid to flow through a filter and the fluid pump; and a milling face including a bit and configured to perform a milling operation while fluid is flowing through the bailer portion.

Method and system for simultaneous wireline milling and debris collection

A milling system may be used to remove the portions of a failed valve that is blocking the wellbore. When milling a partially open valve obstructing the wellbore, the target material to be removed may not be present at the central axis of the wellbore causing the target material to not fully surround the milling bit, which may cause the bit to be deflected away from the target during milling reducing milling efficiency. The disclosed milling system may be used to mill out and capture the coupon for any downhole obstruction that does not have any material near the center axis of the wellbore. A first embodiment of the milling system may be configured to fully mill out material within the wellbore while a second embodiment may be used to mill out material within the wellbore and further catch the milled material or coupon.

Milling and catching devices

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.

Cutting tool and controls for downhole mechanical services

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.

Slot cutter system and operations

Examples described herein include systems and methods associated with a mechanical service tool. In one example, the service tool includes a power jar, an accelerator, and a linear actuator. The accelerator can be coupled to the power jar and provide assistance to the power jar. The linear actuator can be coupled to the accelerator and configured such to pull the accelerator spring within the accelerator with a force sufficient to fire the power jar. When the power jar is in a released state, the linear actuator can also be used to push or pull the entire accelerator and power jar assembly, which in turn can push or pull the target object within the wellbore. The linear actuator can also be used to move the power jar from a released state to a set state.
