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.

A method and system for retrieving a fracturing ball in a wellbore casing. The system includes a wellbore retrieval tool comprising a tool body that is inserted into and transported along the wellbore casing. The tool is sized and configured to trap and hold the fracturing ball. When a hydraulic lock happens in the wellbore casing, the retrieval tool is lowered in a vertical section and the ball is flowed back along a horizontal section and captured by a trap in the retrieval tool. The retrieval tool may also be run in conjunction with a setting tool with a ball-in-place fracturing plug. In case of the hydraulic lock, the injection is tested following perforation with the retrieval tool still a location proximal to the ball, and the ball is immediately retrieved.

A clamp device that attaches an umbilical to a drill string incorporates a junk basket. The basket is notched to accept the umbilical and an insert piece is slipped into the notch after the umbilical is properly in position. The insert piece straddles the umbilical and is secured the balance of the basket to complete the basket. The basket can be slipped over the drill pipe and either secured directly to the outer surface of the drill pipe or against a support member that is supported off the drill pipe. One or more of such baskets can be used and they can also function as umbilical clamps. The basket can also be vertically split to allow mounting it over the drill pipe and umbilical without having to slip it over an end of the drill pipe as the drill pipe is tripped into or out of the hole.

Described is a system for milling past wellbore restrictions. The system includes multiple components axially connected to form a bottom hole assembly (BHA). The BHA includes an external coil connector, a motor head assembly (MHA), a metal-to-metal (MTM) motor, a bypass circulation valve (BCV), and a mill component.
